Bacterial Infection Staphyloccocus aureus and Pseudomonas aeruginosa are two bacterial strains commonly associated with bacterial keratitis.
Viral Infection The two herpes virus strains, herpes zoster and herpes simplex, may attack the cornea, leading to herpes zoster keratitis and herpes simplex keratitis respectively. Parasitic Infection Parasitic infection in the eyes is a common cause of keratitis in people who wear unclean contact lens.
Allergic reaction Severe allergic reactions that occur when the eyes are exposed to allergens may cause inflammation of the cornea. Exposure to Intense UV Radiation Keratitis can develop when your eyes are exposed to intense ultraviolet rays. Keratitis Risk Factors Wearing Contact Lenses Contact lens wearers have a significantly higher risk of keratitis. Wearing the same contact lenses continuously, using water for cleaning and storing the lenses or wearing lenses while swimming boosts the risk of keratitis. Poor Immunity The risk of developing viral, bacterial, fungal and parasitic keratitis is higher in people with weakened immune system.
Corticosteroid Eye Drop Use Using corticosteroid eye drops for treating an eye problem increases the risk of keratitis especially when used for a prolonged period. Inadequate Eye Protection There is a higher risk of developing keratitis when the eyes are not protected properly while swimming and working in the garden, dusty sites and snowy landscapes or when working with chemicals or intense ultraviolet radiation. Symptoms of Keratitis Eye Redness Redness in the eyes is the most common symptom of keratitis. Vision Problems As a significant proportion of the optical power of the eye is controlled by the cornea, damage to the cornea due to keratitis may affect the vision. Sensitivity to Light People suffering from keratitis experience enhanced sensitivity to light.
Keratitis Treatment Removing foreign body from the eye provides prompt relief from noninfectious keratitis that occurs when an irritant or chemical has entered the eye. Corticosteroid Eye Drop Corticosteroid eye drops are frequently prescribed for reducing the inflammation of the cornea and diminishing the risk of scarring. Antibacterial Medication When a bacterial infection is associated with keratitis, antibacterial eye drops or ointments are used for treating the infection. Antiviral For treating viral infections of the cornea, in addition to antiviral eye drops you will need oral antiviral drugs.
Antifungal Medications Topical application of antifungal medication helps to cure keratitis caused by a fungal infection.
Cycloplegic Eye Drop For treating severe keratitis that increases sensitivity of the affected eye to light, cycloplegic eye drops, which help to dilate the pupil, are prescribed by doctors. Analgesic Eye pain caused by keratitis is usually treated with nonsteroidal anti-inflammatory drugs or paracetamols. A corneal infection is an infection of the cornea, the clear section in front of the eyeball that allows light into the eye (find out more about how the eye works). Corneal infections usually occur because of exposure to bacterial, viral or microbiological agents that cause the eyes to become red and swollen. Apart from contact lens related infections, infections can also occur due to existing abnormalities or disturbances of the eye surface or cornea or in cases of eye injury. Corneal infections after eye trauma can also be prevented in work site-related injuries with the appropriate use of safety googles.
Surgery for corneal infections may be indicated in very severe infections or when the infection is not responding to medical treatment i.e.
Joint Commission International (JCI) accreditation is internationally recognized as a premier credential for hospitals and other medical institutions. The Excellence for Singapore Award was set up by the Singapore Totalisator Board in 1996 to recognise and honour individuals, groups of individuals or organisations that bring credit to Singapore by being among the best in their areas of activity in Asia or in the world. ISO 9001 is the globally implemented standard for providing assurance about the ability to satisfy quality requirements and to enhance customer satisfaction in supplier-customer relationships.
The Excellent Service Award (EXSA) is a national award managed by SPRING Singapore and nine industry lead associations.
Servi-CertTM is a service certification adapted from France and introduced into Singapore by the SGS International Certification Services Singapore Pte Ltd. The Singapore HEALTH (Helping Employees Achieve Life-Time Health) Award is presented by the Health Promotion Board to give national recognition to organisations with commendable Workplace Health Promotion (WHP) programmes. As Singapore’s largest integrated healthcare provider and leading international medical group, SingHealth’s hospitals and Specialty Centres are recognised as tertiary centres.


The Ophthalmology & Visual Sciences ACP (EYE-ACP), launched jointly by SingHealth and Duke-NUS, is a cluster-wide framework for all ophthalmologists to advance in Academic Medicine with resources and funding support.
However, it should be known that both, HSV Type I and HSV Type II can cause infection of eyes.
The herpes keratitis which is caused due to affliction of herpes simplex virus shows some signs and symptoms.
Dendriotic corneal lesion, is in fact the determinant symptom of HSV infection which is usually noticed with stromal keratitis in case of advanced or severe condition. Check out Herpes Simplex Keratitis pictures to see how the eye looks under the influence of this disorder or viral infection. Herpes Keratitis virus remains dormant or inactive, dwelling in the cells of nerves in the eye, after its affliction or active phase. Incase herpes simplex virus is dwelling in eye; it normally contaminates the eyelids, cornea or conjunctiva or the eye. The herpes simplex keratitis (corneal infection or ulcer) treatment may depend on the severity of the condition.
Some health care experts suggest degrading the ulcer to eradicate cells of active virus; but this solution has not shown any faster results. The transparent part of the eye at the front, which covers the anterior chamber, the iris and the pupil, is called the cornea.
Pseudomonas aeruginosa infection, which usually occurs by wearing contact lenses contaminated with the bacteria, leads to a severe form of keratitis that causes permanent loss of vision.
Viral keratitis may also develop if the virus associated with Chlamydia invades the cornea. This infectious keratitis, also known as amoebic keratitis, is caused by microscopic parasites called acanthamoeba. Damage caused by trauma may trigger inflammation of the cornea, causing noninfectious keratitis. People who have experienced a severe eye injury that had damaged the cornea are especially susceptible to noninfectious as well as infectious keratitis.
Poor immunity could be caused by an underlying disease or medications that suppress immune function.
In case of moderate to severe bacterial infections, oral antibiotics are needed for curing the infection. Although antivirals reduce the duration of the infection and reduce the risk of complications, they may not eliminate the virus completely from the body. Severe pain that does not respond to standard analgesic medications is usually treated with opiates. The yearly incidence of infections related to contact lens wear varies between 1 in 10,000 hard contact lens users, 4 in 10,000 soft contact lens users to 22 in 10,000 extended wear contact lens wearers. In severe cases, it can cause changes to the corneal shape leading to astigmatism, opacification of the cornea from scarring or a combination of both. Avoiding contact lens wear completely in patients who have predisposing diseases of the cornea or surface of the eye may be necessary.
It is an international mark and endorsement for quality patient care and safety, and organisation management. It is an important way of honouring organisations that strive to help their employees lead healthy and vibrant lives. SingHealth institutions are equipped with highly advanced medical technology and offers pioneering treatments in a wide range of medical procedures, with outcomes comparable with the best institutions worldwide.
Key appointment holders appointed include chair, and vice chairs for education and research. The most common symptom of herpes simplex keratitis is reddened eye with varying intensity of pain or irritation. The lesions may start as an unremarkable or ordinary punctuate disease of eyes (keratopathies). In some cases the infection may also affect the internal portion of the eye; which is found in seldom cases. It is essential to seek treatment for infection immediately; herpes keratitis may penetrate and become severe. If you determine that your infection is a case of active epithelial herpes simplex virus, then you should avert use of topical steroids. It is a serious condition which can progress to adverse consequences if not treated timely.


The yearly incidence of vision loss from contact lens related infections has been estimated to be approximately 0.6 in 10,000 users in studies carried out in Australia and India.
In most cases, patients with severe corneal infections are admitted into hospital and samples from the infection are taken to identify the likely organism before the start of the treatment.
Surgery may also be indicated later on if vision is reduced due to corneal scarring from the infection. The JCI accreditation program initiated in 1999 was designed to evaluate all the functions of acute care hospitals and medical centres. SNEC has progressed from the Bronze Award in 2002 to Silver then to the Gold Award in 2005, 2006, 2008,2010 and 2012.
To ensure the healthcare outcomes are world-class, the Ophthalmology & Visual Sciences ACP will be focusing on developing a comprehensive framework of existing well-established research capabilities in SERI and the training capabilities in SNEC. This condition is also transferrable by coming in contact with active viruses and then touching your own eyes. Other common symptoms may also include photophobia as well as epistrophe; however, ocular ability may be afflicted or may be unhindered, depending on the condition of the corneal lesion.
However, the conditions may insidiously and quickly combine and alter to form a pattern with bright stain of the protein dye, Sodium fluorescein. It should be noted that Type I HVS is highly contagious and can be transmitted through direct contact between skin and infected source. One of the treatments of this infectious condition is 1% topical trifluridine give to the patient every two hours and approx nine times on daily basis.
It is studied that such viruses multiply themselves rapidly when steroids are present in the body or around the afflicted region. Hence; affected individuals should opt for herpes keratitis symptom as soon as the affliction is determined.
HSV-1 often causes sores (lesions) inside the mouth, such as cold sores (fever blisters), or infection of the eye (especially the conjunctiva and cornea).
The fungal keratitis may cause severe damage to the cornea if not treated at the early stage of infection. Treatment with intensive eye drops is administered and adjusted until the infection improves. Surgery carried out in these situations aims to remove the diseased cornea (where scarring or severe infections is present) and replace the removed cornea with a corneal graft or transplant.
Follicular conjunctivitis as well as vesicular skin lesions or rashes can be seen during the initial stage of infection. In case any of the symptoms of herpes keratitis is experienced one should seek immediate treatment; as if the condition is left untreated it may cause severe eye damages. This kind of infection usually affects during childhood, but approximately 90% of the entire population is exposed to such Type I infection.
If ignored, severe complications may develop, leading to permanent damage to the vision of the affected eye. The best way to determine appropriate dosage according to the infection is by consulting a certified doctor. According to a recent study it is determined that reoccurrence of herpes simplex keratitis is reduced significantly with help of oral acyclovir. However, a more frequently noticed symptom is uveitis which is inflammation of uvea portion of the eye. However, the dosage can be reduced to q3-4h which may gradually ebb away the lesions within 8 to 10 days. The likelihood of childhood infection is higher among those with lower socioeconomic status. Herpes simplex virus 2 (HSV-2) is usually, but not always, sexually transmitted. Sometimes, young children also can get the disease. HSV can infect a fetus and cause abnormalities.
A mother who is infected with HSV may transmit the virus to her newborn during vaginal delivery, especially if the mother has an active infection at the time of delivery. However, 60 - 80% of HSV infections acquired by newborns occur in women who do NOT have symptoms of HSV infection or a history of genital HSV infection. It's possible for the virus to be transmitted even when there are no symptoms or visible sores.
The infection may be more severe and last longer in people who have a condition that weakens the immune system. Once an infection occurs, the virus spreads to nerve cells and stays in the body for the rest of a person's life.
