While the red eye is a very frequent complaint in the ED, there are no definite data on its overall prevalence.4 The most common causes of the red eye include viral, bacterial, and allergic conjunctivitis. FunduscopyFunduscopy rarely provides useful information in the red eye, as most etiologies involve processes in the anterior rather than posterior portion of the globe. BlepharitisBlepharitis is an acute or chronic inflammation of the eyelids, often accompanied by conjunctival irritation.

And covers the surface of the membrane that covers the inner side of the front of the conjunctiva of the eye structure of the tissue. Bacterial ConjunctivitisSudden onset, eye burning, stinging, redness, ocular discharge makes lashes stick. What is Conjunctivitis?The inner surface of the eyelids and covers the white part of the eye is called conjunctivitis iltahabA±na thin and transparent membrane. If your infection is bacterial, your doctor may prescribe antibiotic eye drops and the infection should go away within several days. Antiviral medications may be an option if your doctor determines that your viral conjunctivitis is caused by the herpes simplex virus.
If the irritation is allergic conjunctivitis, your doctor may prescribe one of many different types of eye drops for people with allergies.
Canine conjunctivitis is an inflammation of the conjunctiva, which is the delicate transparent layer of tissue that covers the front part of the eye, the inside of the eyelids, and your dog's third eyelid. There are many different causes of pink eye in dogs and your vet will try to work out which one he's dealing with so that he can treat it properly. If it's bacterial, the culprit is likely to be the streptococcus or staphylococcus bacterium. Neonatal conjunctivitis is caused by a bacterial infection and affects young puppies, but it can also affect newborn puppies, even though their eyes don't open until they're around 2 weeks old! If it's a bacterial infection, your pet will need an antibiotic, which may be in the form of an injection, an ointment, or tablets.
Treatment will vary depending on the condition, but the vet will treat the actual eye problem that's causing the conjunctivitis (for example, entropion or glaucoma) and, in the meanwhile, will prescribe something to soothe the symptoms of the conjunctivitis. By staying up to date with all vaccinations we can protect our pets against other canine diseases that can cause conjunctivitis, such as distemper - one less thing to worry about!

Conjunctivitis is an inflammatory process involving the surface of the eye and characterized by vascular dilation, cellular infiltration, and exudation.
Symptoms: Typical symptoms exhibited by all patients include reddened eyes and sticky eyelids in the morning due to increased secretion. Diagnostic considerations: There are many causes of conjunctivitis, and the clinical picture and symptoms can vary considerably between individual patients.
H The combination and severity of individual symptoms usually provide essential information that helps to identify the respective presenting form of conjunctivitis. If the diagnosis is uncertain or what appears to be bacterial conjunctivitis does not respond to antibiotics, a conjunctival smear (Fig.
An antibiotic that is not effective in treating what appears to be bacterial conjunctivitis should be discontinued.
While emergency physicians are capable of treating the majority of patients who complain of a red eye, it is important to differentiate benign and selflimited conditions from more serious processes.
Other aspects of the physical examination will vary depending on the clinical presentation. It may be caused by a variety of bacterial, viral, or parasitic infections as well as allergic, systemic, or dermatological diseases. Microbial causes a large amount of red and rheumy eyes conjunctivitis will discharge very rheumy eye doctor will need to apply and an indication of an infection in acute situations.
Both viral and bacterial conjunctivitis are extremely common and very contagious among children. The conjunctiva is the thin clear tissue that lies over the white part of the eye and lines the inside of the eyelid. Antibiotic eye ointment, in place of eye drops, is sometimes prescribed for treating bacterial pink eye in children. These may include antihistamines, decongestants, mast cell stabilizers, steroids and anti-inflammatory drops.
Find all you need here; symptoms, causes, diagnosis and treatment - everything you need to keep your precious Cocker Spaniel's eyes healthy! Do your best to stop this, because any rubbing could damage his eyes (more so than the actual conjunctivitis).
Clear any gunk from the corners and gently wipe around the eye area using a piece of cotton wool soaked in saline solution or an eye-cleaner recommended by your vet. Keep the dreaded pink eye at bay! Onset is abrupt and initially unilateral with inflammation of the second eye within one week.
Any conjunctivitis also causes swelling of the eyelid, which will appear partially closed (pseudoptosis). This makes it all the more important to note certain characteristic findings that permit an accurate diagnosis, such as the type of exudation, conjunctival findings, or swollen preauricular lymph nodes (Table 4.1). 4.7 Clearly visible, bright red, distended conjunctival vessels, decreasing toward the lim-bus of the cornea. The quantity and nature of the exudate (mucoid, purulent, watery, ropy, or bloody) depend on the etiology (see Table 4.1).
This may range from the absence of any conjunctival thickening to a white glassy edema and swelling of the conjunctiva projecting from the palpebral fissure (chemosis this severe occurs with bacterial and allergic conjunctivitis).
Lymphocytes in the palpebral and bulbar conjunctiva accumulate in punctate masses of lymph tissue cells that have a granular appearance. Conjunctival or vascular ingrowth between Bowman's layer and the corneal epithelium in the upper circumference. These are inflamed nodes of conjunctival stroma with circumscribed areas of reddening and vascular injection. This is performed to examine the upper and lower eyelids for the presence of follicles, papillae, membranes, and foreign bodies.
This is used to detect chlamydiae in particular and to more clearly identify the pathogen in general. 4.12 The lower eyelid is slightly everted and a smear of the conjunctival secretion is ob tained with a cotton swab. Slit lamp, ophthalmoscopy, measurement of intraocular pressure (IOP), and fluorescein staining should be considered if directed by the history or other facets of the physical examination.
Patients with bacterial conjunctivitis often give a history of morning crusting and difficulty opening the eyelids.25 While patients complain of irritation, they are spared deep orbital pain and suffer no visual loss. Blepharitis is divided into three main categories: staphylococcal or seborrheic (both of which involve the anterior eyelid) and meibomian gland dysfunction (which involves the posterior eyelid). Sometimes, even without inflammation, especially during childhood may develop allergic conjunctivitis reasons.Conjuntivitis microbial causes redness and ocular discharge the main complaints that are prominent especially in the morning. On the other hand very little burr conjunctivitis be caused by some other microbes, and the edges of the cover are seen only in the morning.
Conjunctivitis is one of the signs and symptoms of disease were observed in the first transmit the disease in the next seven to 14 days. Eyes thoroughly with boiled water or sterile saline soak petlerini eyes of the child may be deleted. Chlamydia-infected people floating in the pool floats and inadequate chlorination towel used by one of the persons or persons with chlamydial conjunctivitis can contract the pool.
Inflammation causes small blood vessels in the conjunctiva to become more prominent, which is what causes the pink or red cast to the whites of the eyes. An ointment is often easier to administer to an infant or young child than are eye drops, though the ointment may blur vision for up to 20 minutes after application. Viral conjunctivitis often begins in one eye and then infects the other eye within a few days. Foreign-body sensation, a sensation of pressure, and a burning sensation are usually present, although these symptoms may vary between individual patients. The conjunctival injection is due to increased filling of the conjunctival blood vessels, which occurs most prominently in the conjunctival fornices. Illacrimation is usually reflex lacrimation in reaction to a conjunc-tival or corneal foreign body or toxic irritation. They form from necrotic epithelial tissue and either can be easily removed without bleeding (pseudomembranes) or leave behind a bleeding surface when they are removed (membranes; Figs. Swollen lymph nodes are an important and frequently encountered diagnostic sign of viral conjunctivitis.
They can occur with systemic disorders such as tuberculosis or sarcoidosis or may be exogenous, such as postoperative suture granulomas or other foreign-body granulomas. Cotton swabs with sterile shipping tubes are commercially available; special test kits with specific cultures are available for detecting chlamydiae. Microbiological examination to identify the pathogen is indicated for any conjunctivitis in children.
These conditions may be difficult to differentiate on initial examination.Keratoconjunctivitis sicca, a condition of low tear volume, is associated with up to 50% of staphylococcalblepharitis cases. Microbes are discussed reviewing, loop again infect your child uses hand towel paper towel apart, or better yet use the child to provide the household wash their hands more often, door handles, telephone receivers, toys ellenen places as often frequent deletion of the child's other family members and to protect the eyes measures that can be taken to.One of the most important issues to be considered disorders conjunctivitis, Conjunctivitis your child is sent to school and the school is definitely the slot or warn against the possibility of epidemics. Conjunctivitis can be caused by many of the bacteria and viruses responsible for colds and other infections, including ear infections, sinus infections, and sore throats. Granulomas occur in conjunction with swollen preauricular and subman-dibular lymph nodes in disorders such as Parinaud's oculoglandular syndrome. Because the child is not yet a germ carrier state and the symptoms until it is free from a friend who might be other friends got a little.Adenoviral conjunctivitisUnlike bacterial conjunctivitis Viral conjunctivitis is contagious, and many more do not see the benefit from antibiotics.
Especially dust escaping from the bottom of the lens on the cornea can lead to bacterial infection and ulcers.Konjonktivit'te What are the risk factors?Exposure to allergic conjunctivitis allergy to a substance which, like viral or bacterial conjunctivitis is a risk of contact with someone who is infected. Follow your doctor’s instructions and use the antibiotics until your prescription runs out, to prevent recurrence of the infection. Viral conjunctivitis is often very contagious and patients should practice good hand washing and should avoid hand-eye contact. However, the visibility of the hyperemic vessels and their location and size are important criteria for differential diagnosis.
Granulomas are not a sign of conjunctivitis in the strict sense and for that reason have not been included as symptoms or findings in Table 4.1.
The lower lacrimal system should always be irrigated in the presence of inflammation that recurs or resists treatment to verify or exclude that it is the source of the inflammation. It is traditionally quantified using the Snellen chart, with the patient standing at a preset distance.
The staphylococcal variety tends to have hard, crusty deposits at the lid margins, whereas those of the seborrheic type are often oily or greasy.51 The magnitude of the findings reflects the severity and the chronicity of the disease.


In particular the so-called adenoviral conjunctivitis, viral conjunctivitis is highly contagious and can cause outbreaks. Although it develops after some adenoviral infections of upper respiratory tract infections, it is not essential.
These cases tend to happen more frequently among kids who also have other allergic conditions, such as hay fever. Dogs will be dogs and we can't wrap them in cotton wool, but we can at least try anyway, can't we? Simultaneous presence of blepharospasm suggests corneal involvement (keratoconjunctivitis). One can also distinguish conjunctivitis from other disorders such as scleritis or keratitis according to the injection (Fig. For this reason, patients with conjunctivitis wipes, towels, pillows, such as the separation of goods, frequently wash their hands, avoid girmektan pool and a handshake should avoid. Microbial and viral conjunctivitis is highly contagious and wipes, towels, pillows can be transferred through items such as. More than 60% of patients with sudden onset of both eyes, redness, tearing, eyelid swelling is seen. Conjunctivitis is one of the signs and symptoms of disease were observed in the first transmit the disease in the next seven to 14 days.Conjunctivitis Why does it occur?a€? Infections caused by viruses or bacteriaa€? Tear deficiency, caused by exposure to too much sunlight, wind, or eye drynessa€? Chemicals, fumes and smoke (chemical conjunctivitis)a€? Allergya€? Dust, hair, or foreign objects such as sand,Konjonktivit'ten How to protect yourself?To avoid inflammation of the eye disease, also known as conjunctivitis, is very important to follow the rules of basic health.
Triggers of allergic conjunctivitis include grass, ragweed pollen, animal dander, and dust mites. If the patient is illiterate or pre-verbal, use a picture chart or “tumbling E” chart (in which the patient may indicate which way the “E” is facing with his or her fingers). Cultures of the lid margins may be done for recurrent, severe inflammation or cases resistant to standard therapy. Sometimes a substance in the environment can irritate the eyes and cause conjunctivitis, such as chemicals (chlorine, soaps, etc.) or air pollutants (smoke and fumes). Because microbial agent may infect your friends.Review of all the burrs should be removed before drug instillation.
Swimming-pool maintenance should be done carefully, infected persons should not enter the pool. A lot of us merely don't have enough motivation to alter our habits all of our foul habits in a way that would really affect our life. If the patient is unable to see either chart, walk the patient one half the distance to the chart and attempt again. Instruct the patient to apply the ointment to the lid margins several times daily for one or more weeks. From your hand in front of the ear and under the chin, touched adenoviral conjunctivitis, painful lymph glands also likely to be present if you find your child. In addition, every public place (including means of transport) should be disinfected on a regular basis.
If the patient can read the chart, the numerator of the visual acuity documented will be 10 instead of 20.Another option is to ask the patient to look through a pinhole. For resistant and severe inflammation, a one- to three-week course of topical steroids is often used. This disease is not only an eye membranes, transparent layer of the eye called the cornea, eye doctor to see the affects are required for diagnosis.There is no known treatment of a drug. Many topical antibiotics (drugs given as eye drops or ointment) are effective for treating bacterial conjunctivitis.
In one series, keratitis, anterior chamber inflammation, periocular edema and tenderness, gaze restriction, and preauricular lymphadenopathy were common.31 The initial evaluation should look for evidence of corneal infiltrates or ulcerations. Most patients with blepharitis need to be counseled about the chronicity of the problem, the likelihood of recurrent flare-ups, and the need for a regular regimen of lid hygiene.
Hands and door handles, toys ellenen places as often frequent deletion of the child's family members and other measures that can be taken to protect the eyes.Allergic conjunctivitis is usually begin in childhood, and also known as hay fever. Taking a very short incubation period of the virus is the virus, the disease can occur within 24-48 hours. Your healthcare provider may prescribe antibiotic eye drops or ointment as conjunctivitis treatment, and the infection should clear within several days. An alternative to the pinhole is to have the patient use a hand-held ophthalmoscope when reading the chart. 50 Patients with keratoconjunctivitis sicca are managed initially with artificial tear supplements.Pinguecula And PterygiumPinguecula, a benign degeneration of the conjunctiva related to UV light exposure and aging, appears as a fatty-looking yellow spot, usually on the nasal aspect of the conjunctiva. Redness and itching side of the main complaints that sneezing, runny nose and itching may occur.
Artificial tears and cold compresses may be used to relieve some of the dryness and inflammation.However, mild bacterial conjunctivitis may get better without antibiotic treatment and without any severe complications. The use of antibiotics is associated with increased antibiotic resistance and increased costs, and should be a shared decision between the doctor and the patient (Crounau, 2010). It appears as a raised, yellowish, fleshy lesion, usually on the nasal aspect of the bulbar conjunctiva. It usually extends only to the peripheral cornea, seldom interfering with vision.4 Occasionally these lesions become inflamed, leading to complaints of eye irritation, foreign body sensation, pain, or tearing.
The External Eye ExaminationInspect the skin around the eyes as well as the lids and lid margins for rashes, swelling, vesicles, discoloration, and malposition of the lids.
Chlamydial conjunctivitis, a less serious disease, is caused by different serovars than trachoma. The PupilThe size of the pupil and its response to light and accommodation may help narrow the differential diagnosis. Corneal abrasions from contact lenses represent a separate category with a unique set of clinical problems.
In one study of more than 300 consecutive patients presenting to an eye clinic with a unilateral red eye, the presence of miosis (small pupil) in the affected eye was a fairly reliable indicator of iritis.8Miosis is often secondary to spasm of the ciliary muscle.
In a one-year survey of admissions to a British emergency eye clinic, corneal abrasions accounted for 10% of the visits.54Corneal abrasions are quite painful, and most people do not return to full functioning until the abrasion is healed. While miosis is a nonspecific response to inflammation or injury, it generally indicates a disease process deep to the cornea.
Patients describe immediate, sharp pain followed rapidly by tearing, photophobia, a decrease in visual acuity, and a persistent foreign body sensation. Topical anesthetic drops will often significantly improve the pain, reduce blepharospasm, and allow a full examination. To perform this test, have the patient look across the room and then quickly look at your finger held a few inches in front of their face.
Among the most important are the adenoviruses, often associated with epidemic keratoconjunctivitis.
The magnification provided by a slit lamp allows a detailed quantification of the size as well as the depth of the lesion. Transmission is most commonly from hand to eye, but other vectors include contaminated tonometers, improper hand-washing technique, and contaminated swimming pools. Subtle abnormalities or small foreign bodies involving the cornea and palpebral conjunctiva are often best visualized with the slit lamp. Epidemics may occur in densely populated habitats, such as military outposts or school dormitories.Viral conjunctivitis usually presents with diffuse conjunctival redness, lid edema, and a copious, waterydischarge. Except in the cases of abrasions associated with contact lens use, infection occurs in fewer than 1% of cases. The device provides a better assessment of corneal defects or infiltrates than ophthalmoscopy or visual inspection.Some physicians routinely have trouble using the slit lamp.
Until the mid-1990s, accepted therapy involved occlusive eye patches, antibiotic ointments (felt to be more soothing than drops), oral analgesics, and optional cycloplegics.
A preauricular lymph node, while characteristic (and also seen with chlamydial infections), is not always present. The theory behind the occlusive patches was to provide a stable corneal environment to promote rapid reepithelialization. These include maintaining the patient’s forehead against the restraining strap, using a narrow, bright light at a very oblique angle, and moving the joystick of the slit lamp forward and backward to focus on various points between the cornea and iris. Other distinctive findings may include subconjunctival hemorrhage, corneal erosions, or punctate keratitis. Large abrasions seem to enjoy improved healing if patched.56Unlike eye patching, topical NSAID drops may improve patient comfort.
Topical steroids are used only when  keratitis is present (see the subsequent section on keratitis). In one randomized, double-blind, placebo-controlled trial of 100 patients with corneal abrasions, topical ketorolac 0.5% (Acular) was shown to reduce pain and photophobia significantly at the one-day mark. In one study, two separate, blinded ophthalmologists examined 98 successive patients presenting with a red eye to an emergency ophthalmology service; their findings were recorded independently. In patients with a conjunctival membrane (membranous conjunctivitis), debridement of this casing followed by topical steroids may hasten recovery.5 While some authorities recommend topical antibiotics, ostensibly to prevent secondary bacterial infection, there is little evidence and no trials within the past 15 years to support this practice.
The ketorolac group was also able to return to function one day sooner, on average, than the placebo group. The physician limited to the ophthalmoscope was asked to indicate if a slit lamp examination was indicated (an effort to mimic the general practitioner requesting an eye consult). An incorrect diagnosis was made in four of the non-slitlamp patients (three had anterior uveitis); however, in each case, the examining physician had clinical suspicion of a potentially serious problem.
Each of these patients had findings consistent with iritis—photophobia or deep, aching pain made worse on accommodation.12Topical AnestheticsPatients with acute eye irritation may require topical anesthesia to cooperate with the examination. This needs to be taken into account when advising healthcare or daycare workers on when to return to work. They are all at increased risk of developing infected abrasions—referred to as ulcerative keratitis. Most adults who can maintain careful hygienic measures can return to work before the conjunctivitis has resolved.37 The emergency physician should be acutely aware of potential patient-tophysician (and then to another patient) transmission.
These agents facilitate lid eversion, tonometry, fluorescein staining, and examination of the patient with severe eye pain. Use disposable gloves during the examination and wash hands vigorously after touching a patient with conjunctivitis.Allergic ConjunctivitisAllergic conjunctivitis is often a seasonal phenomenon in sensitive individuals. In addition, topical anesthesia can help differentiate pain due to simple corneal injury from pain due to iritis, glaucoma, or other serious eye problems.
Vernal and atopic conjunctivitis are chronic conditions that begin in childhood and wax and  wane for decades before recurrences finally cease. The course can be fulminant, leading to permanent vision loss from corneal scarring.Do not patch corneal abrasions secondary to contact lens use. Some patients develop ocular symptoms during a generalized allergic flare, in response to a specific allergen such as cat dander, or in response to certain ophthalmic preparations (Neomycin being the classic). In 1987, Clemons et al reported six cases of Pseudomonas keratitis following pressure patching for contact-lensassociated corneal abrasions.58 The occlusive patch favors bacterial replication by raising corneal temperature and interfering in the normal protective effects of routine eye blinking, tear exchange, and tear movement.
The usual practice in this clinic was to use one bottle of anesthetic drops for each slit lamp for an entire day, after which the opened bottles were discarded. Normally, the anesthetic is instilled prior to the fluorescein, but for this study, it was instilled afterward.
On physical exam, both eyes are usually injected, and the bulbar conjunctiva is often strikingly edematous (chemosis).


Follow-up within 24 hours should be arranged, because suppuration of the abrasions can occur rapidly. In atopic conjunctivitis, the eyelids may become thickened or scarred, with loss of eyelashes. Simply ask the patient to look down while you place a small, cotton-tipped applicator at the midpoint of the upper lid—then firmly grasp the eyelashes and pull them gently over the applicator. In the case of UV keratitis, symptoms may not begin until 8-12 hours after exposure, prompting a nighttime visit to the ED. The undersurface of the lid containing the palpebral or tarsal conjunctiva can now be examined for foreign bodies or other abnormalities. In contact-lens-associated giant papillary conjunctivitis, large, square papillae (often described as cobblestones) are present on the palpebral conjunctivae, best seen by inverting the lower lid. In mild cases, removing the allergen (such as the eyedrops), if possible, using warm compresses, andavoiding eye-rubbing may be all that is needed.
It is the tonometer preferred by the AAO (A-III); however, it requires significant training in use and calibration. 6 During the past 10 years, a small, highly portable electronic device called the Tono-pen has appeared on the market. Acanthamoeba, fungi, herpes simplex virus (HSV), and herpes zoster (HZ) have also been implicated. The normal cornea is quite resistant to infection, due to the tight junctions between the top two layers of the cornea.
The Tonopen is as accurate as the Goldmann tonometer in the usual physiologic ranges (10-30 mmHg).
However, it slightly overestimates pressures in the low ranges and, more importantly, underestimates pressures in the high ranges. Parasitic, viral, or fungal infections may present in a more indolent fashion.The presence of corneal abnormalities on physical examination differentiates ulcers from uncomplicated conjunctivitis.
It is appropriate for general screening, but probably not in glaucoma clinics, where fine-tuning of pressures at the high end is needed.20,21The Schiotz tonometer is still in use in many EDs and outpatient clinics. The raised margins and crater of the ulcer can clearly be seen with the slit lamp, and the ulcer will stain intensely with fluorescein. The resultant deflection on the scale must then be converted using a supplied chart to arrive at the IOP reading. The use of Gram’s stain, culture, and scrapings from the ulcer margins remains controversial.
It is important to remember that the lower the measurement on the Schiotz, the higher the IOP. A survey of ophthalmologists in Southern California revealed that fewer than half used culture prior to initiating antibiotic therapy.
The Schiotz is somewhat cumbersome to use, can only be used in cooperative patients in the supine position, and must be cleaned thoroughly after each use. To use the Schiotz to its best advantage, it is helpful to ask the patient to look at a spot on the ceiling directly in front of their eye, taking care not to apply pressure to the globe when the eyelids are retracted.Whichever tonometer is used, be sure to disinfect the contact surface against viruses and bacteria properly if disposable tips are not used. An effective solution is sodium hypochlorite (bleach) at 500 ppm.22While tonometry is the most objective means to determine IOP, digital ballottement of the eye can provide important information.
Cultures of the patient’s contact lenses, lens case, or cleaning solution may be useful when acanthamoeba infection is suspected.62Four to six percent of ulcers do not respond to initial therapy.
Because of the high potential for complications, such as corneal scarring, decreased vision, endophthalmitis, and ultimate enucleation, an ophthalmologist should be involved early in the care of such patients. The lower lid is gently retracted, and the tip of a moistened fluorescein strip is touched to the lower conjunctival sulcus.
Specific directions for reconstituting these preparations can be found in the AAO Preferred Practice Pattern issue on bacterial keratitis.62Loading doses of any of these medications are usually begun on a 5- to 15-minute cycle followed by every hour instillation for the first 24 hours.
Alternatively, hold the strip above the eye and apply a drop of sterile irrigant to it, allowing the florescent drop to plop into the conjunctival sac.
If topical steroids were being used, they should be discontinued, or at least reduced to the minimum amount needed to control the underlying condition. Fluorescein is readily picked up by damaged superficial cells or exposed deeper cells of the cornea. The initiation of topical steroids for corneal ulcers is controversial and without conclusive scientific evidence. Nevertheless, many ophthalmologists continue to use lowdose topical steroids for corneal ulcerations in the belief that they will reduce inflammation.62Many corneal ulcers may be managed on an outpatient basis with daily re-examinations.
Will the patient actually return for next-day follow-up?Acute Anterior UveitisAcute anterior uveitis, also called iritis or iridocyclitis, is an inflammation of the anterior portions of the uvea. The majority of cases are idiopathic; however, uveitis may develop in association with viral infections, HSV, HZ, or AIDS.
Other implicated etiologies include Lyme disease, syphilis, toxoplasmosis, brucellosis, intraocular foreign bodies, and anterior segment ischemia.67Acute iritis may also develop several days after blunt trauma to the eye. Unless specifically questioned, patients may not make the connection between the trauma and their current eye pain (although a “black eye” is a powerful clue).
The eye is injected, with the most marked hyperemia adjacent to the iris (the limbus); this is called limbal injection or flush. As described in the section on the physical examination, testing for a consensual light reflex or accommodation will cause significant pain in the affected eye. The hallmarkof anterior uveitis is the presence of inflammatory cells and “flare” in the anterior chamber on slit lamp exam. The flare (“smoke”), which represents protein in the anterior chamber, is also quantified on a scale of 0-4, such that +1 = very slight, +4 = intense.
Prednisolone (PredForte) is commonly prescribed, given every 1-2 hours initially, then slowly tapered over 3-4 weeks. Intermediate- acting cycloplegics, such as homatropine or scopolamine, are used to control the pain from ciliary spasm.Sympathetic stimulants such as tropicamide (Mydriasil) are inappropriate, as they have no affect on the ciliary constrictor muscle. The cumulative risk of recurrence is estimated at 30% per year.70The most common presenting complaints are irritation, tearing, photophobia, and blurred vision. Past medical history should include questions regarding facial lesions, such as cold sores or blisters, genital lesions, previous episodes of corneal ulcers or iritis, recent topical or systemic steroids, immunosuppressive diseases, or medications.69 Corneal sensation, which may be tested using thin wisps of cotton from a sterile cotton-tipped applicator, is decreased in 80% of cases. When the herpes-infected eye is touched, the corneal reflex may be depressed or the patient may notice decreased sensation in the involved eye.The best diagnostic test in the ED involves slit lamp examination in combination with fluorescein staining. Dendrites are single or multiple masses that have linear branches that end in terminal bulbs. HSV begins as a punctate keratitis, which then progresses to dendritic lesions that then coalesce into geographic ulcerations.
Iritis with a cell or flare reaction on slit lamp exam occurs in 40% of cases.Disease confined to the epithelium responds to topical or oral antiviral agents in 90%-95% of cases. Forty percent of cases resolve spontaneously without sequelae69 (but the ED physician should still treat them). For disease limited to the epithelium, any of the topical or oral preparations are used for 10-14 days. A topical antibiotic preparation is added when ulcers are present.69 Acyclovir is the only oral agent to have been studied in ocular clinical trials.
Their beneficial effects include inhibition of white cell infiltration, scar formation, and neovascularization.
However, they may promote the spread of a superficial viral infection, increase the incidence of bacterial or fungal infections, and result in steroid-induced glaucoma or cataracts. When steroid drops are used, a prophylactic antiviral preparation is added.69 A series of clinical trials by the Herpetic Eye Disease Study (HEDS) multicenter group did not show an improvement in resolution with the addition of oral acyclovir to a topical regimen.
However, a subsequent HEDS trial showed that prophylactic oral acyclovir reduces the rate of recurrent HSV eye infections.71Herpes ZosterLike HSV, HZ is a disease of recrudescence, the virus emerging in specific nerve root distributions years after the original infection.
HZ of the ophthalmic division of the trigeminal nerve (cranial nerve V) represents 10% of total HZ infections. The corneal manifestations vary from punctate keratitis to ulcers to pseudodendrites to deeper stromal keratitis. The characteristic skin lesions accompanied by corneal anesthesia are usually enough to make the diagnosis. A Tzanck smear of vesicular lesions or epithelial scrapings may show multinucleated giant cells but will not differentiate HZ from HSV.
PCR of tear film or corneal scrapings shows promise as a rapid test in hard-to-diagnose cases.70The skin lesions may be treated with a seven- to 10-day course of acyclovir (Zovirax, 800 mg 5 times a day), famcyclovir (Famvir, 500 mg TID), or valacyclovir (Valtrex, 1 g TID). All of these preparations promote healing and reduce pain if given within 72 hours of onset—best if within 48 hours.
However, the incidence of post-herpetic neuralgia, a particular problem in the elderly, is unaffected.73 Topical antivirals have not been shown to be effective in HZ. Topical steroids should be reserved for cases of active stromal keratitis and anterior uveitis, under the direction of an ophthalmologist.70Fungal ConjunctivitisFungal conjunctivitis is initially clinically indistinguishable from bacterial infection. The diagnosis may be suggested by a history of trauma from vegetation or work on a farm or vegetable garden, but sometimes the initial trauma is so mild as to have been forgotten.
Risk factors for PACG include older age, female sex, a history of hyperopia (farsightedness), a family history of acute angle-closure glaucoma, Eskimo or Asian extraction, and a prior history of anterior uveitis.6 The pathophysiology of PACG involves obstruction of the trabecular meshwork. When the entire circumference of the anterior chamber angle is occluded, IOP increases and corneal edema occurs. There are case reports of elderly patients presenting only with nausea and vomiting and generalized headache or with abdominal pain, which results in an extensive GI work-up or even laparotomy.76 While PACG can affect both eyes, an acute attack usually presents unilaterally with a red eye, hazy cornea, and a dilated, minimally reactive pupil.
Using a slit lamp and goniometer, an ophthalmologist can demonstrate that the peripheral iris blocks the trabecular meshwork.
If a skilled observer or slit lamp is unavailable, an “oblique flashlight test” may be used. In this test, a penlight or flashlight is held off to the side and parallel to the iris with the beam shining across the anterior chamber. The initial treatment targets lowering IOP in preparation for definitive surgery.6 Call an ophthalmologist as soon as the diagnosis is made or strongly suspected. Accepted components of acute medical therapy include topical beta-blockers, a topical alphaadrenergic agent (such as apraclonidine), oral or intravenous acetazolamide, topical steroids, and low-dose pilocarpine.76 Intravenous osmotic agents, such as mannitol, are effective in lowering IOP, but they need to be used with great caution in the setting of congestive heart failure or renal insufficiency.
The miotic effect of pilocarpine is blocked at IOPs over 60 mmHg; however, the action on the ciliary muscle and the anterior movement of the lens continue, so that IOP may be paradoxically increased with aggressive use of pilocarpine.
