A 36-year-old female presented to the Emergency Treatment Center (ETC) of the University of Iowa Hospitals and Clinics (UIHC) with one day of right eye pain, photophobia and decreased vision. The following day, her symptoms did not resolve and was therefore referred to the UIHC Cornea service for further evaluation. During the first ten days of treatment, all subjective symptoms resolved with the exception of mild blurring of vision. She returned for routine follow-up one month after discontinuation of topical corticosteroids. HSV keratitis can present with involvement of the corneal epithelium, stroma, or endothelium, with or without associated inflammation of the anterior chamber (Table 1).[1-4] Pathophysiologic manifestations may be related to the presence of live virus, immunological reactions to viral antigen, or secondary to previous herpetic injury ("metaherpetic"), particularly the loss of corneal sensation. The diagnosis of HSV keratitis is primarily clinical, although additional tests may be useful in providing confirmation, but never exclusion.[1-4] The Tzanck (Giemsa) smear of multinucleated epithelial cells is a quick test with high specificity but low sensitivity. HSV epithelial keratitis invariably involves active viral proliferation.[1-4] The classic epithelial dendrite is the most common presentation of epithelial disease (Figure 1). HSV stromal keratitis is associated with the highest and most severe morbidity of any ocular herpetic disease.[1-4] Although this condition frequently follows previous HSV epithelial keratitis, it can be the initial presentation of ocular herpetic disease. HSV disciform (endothelial) keratitis is a cell-mediated immune reaction to corneal endothelial tissue that presents with diffuse stromal edema.[1-4] In approximately half of cases, there is no prior history of HSV epithelial keratitis. HSV keratouveitis may occur as a separate entity or in association with herpetic epithelial, stromal, or endothelial disease.[1-4] It may be granulomatous or non-granulomatous and may, in some cases, be associated with live virus (Figure 6). Metaherpetic manifestations of HSV keratitis include neurotrophic keratopathy and microbial (i.e.
Although HSV epithelial keratitis is self-limited in most cases, the rationale for aggressive antiviral therapy is to prevent corneal nerve damage and potential future immunologic disease.[1] Prior to the advent of antiviral therapy, simple epithelial debridement was the treatment of choice.
The most common mistake in the management of HSV keratitis is premature termination of topical steroid therapy.
In our clinics, the taper for stromal keratitis and keratouveitis is only one-third complete when it has been reduced to prednisolone acetate 1.0% once daily. Our preferred steroid use and taper regimens are based upon whether or not the patient is a steroid-responder. The introduction of oral antiviral prophylaxis constituted a major advance in the management of chronic herpetic eye disease.
There are no uniformly accepted guidelines governing the use of antiviral prophylaxis in conjunction with topical corticosteroid use in situations where live viral manifestations are not present. Late surgical intervention is indicated for management of intractable corneal pain or visual impairment associated with herpetic disease.

Most cases (> 90%) are unilateral, but bilateral cases may occur, especially in atopic or immunocompromised patients.
It represents areas of epithelial breakdown due to cell destruction by proliferating virus and is best demonstrated after fluorescein staining under cobalt blue lighting.


The vast majority of cases are an immune stromal keratitis (ISK), which involves the antibody-complement cascade against retained viral antigens in the stroma.
Accordingly, acute-onset, unilateral corneal edema should be considered to be due to herpetic eye disease unless proven otherwise.
A guiding principle is that prior to the onset of immune-mediated disease, control and elimination of epithelial manifestations is the highest priority. Our experience is that the optimal initial frequency is hourly for NSK, every two hours for ISK, and every three hours for disciform keratitis.
In such cases, there is almost invariably a reappearance of corneal inflammation that is mislabeled as "recurrent" disease, when, in fact, it is actually a "pseudo-recurrence" that is merely a continuation of the same immunological reaction that has now become clinically apparent due to therapeutic withdrawal.
Due to the very high benefit-to-risk ratio associated with oral antiviral therapy, it is our preference to use these medications in every instance in which topical corticosteroids are utilized.
For painful eyes without visual potential, a Gunderson flap will reduce chronic inflammation and eliminate pain. Full dose oral antiviral followed by prophylactic oral antiviral (for 1 year up to indefinitely).
LASIK may lead to herpes simplex virus activation, resulting in sight-threatening herpes simplex keratitis lesions.Problems from Lasik?
The photo below shows the cornea of a patient who developed ectasia and herpes simplex infection after LASIK. In the reported cases of herpetic reactivation after LASIK procedures done via a microkeratome and surface laser ablations, the trauma exerted by lamellar dissection and the ultrviolet light of the excimer laser have been blamed as the potential causes. The virus travels from the skin during contact to the sensory dorsal root ganglion, where latency is established. The mouth lesions (herpetic gingivostomatitis) consist of painful vesicles on a red, swollen base that occur on the lips, gingiva, oral palate, or tongue.
However, if the pattern of the lesions is not specific to HSV, its diagnosis can be made by viral culture, PCR, serology, direct fluorescent antibody testing, or Tzanck test. In one randomized controlled trial (RCT), children receiving acyclovir had oral lesions for a shorter time than children receiving placebo (median of four versus 10 days).
In chronic cases, demonstration of decreased sensation by Cochet-Bonnet aesthesiometry can be helpful in differentiating true recurrent dendritic keratitis from pseudo-dendritic keratitis, especially that related to recurrent epithelial erosions. The presence of keratouveitis mandates a thorough funduscopic examination to exclude concomitant acute retinal necrosis. However, once immune-mediated disease has been established, management of stromal or endothelial manifestations, with their potential for irreversible visual impairment, has higher priority than control of epithelial disease. However, corneal toxicity related to the topical antivirals available in the United States led to a preference on the part of many specialists to rely exclusively on equally effective systemic therapy.
If concomitant epithelial disease is present, full systemic antiviral dosing is also required since steroid therapy exacerbates this condition. For eyes with post-herpetic scarring and good visual potential, the surgical procedure is based upon the corneal pathology. History of herpes keratitis is a contraindication for LASIK surgery, as surgical trauma may trigger reactivation. The diagnosis of an infection with herpes simplex virus type 1 is usually made by the appearance of the lesions (grouped vesicles or ulcers on an erythematous base) and patient history.
Oral HSV-1 infections reactivate from the trigeminal sensory ganglia, affecting the facial, oral, labial, oropharyngeal, and ocular mucosa.Primary infection appears two to 20 days after contact with an infected person. There was, however, patchy anterior stromal inflammation in the visual axis that did not resemble the characteristic post-dendritic "footprints" and was felt to represent early immune stromal keratitis (Figure 2). On examination, the epithelium was intact but there was mild patchy anterior stromal haze in the same distribution in the visual axis as before. Bacterial and fungal cultures, along with confocal microscopy, can be used to rule out other etiologies of microbial keratitis. Our preference is to use acyclovir 400 mg PO five times daily or valacyclovir 1000 mg PO three times daily. Phototherapeutic keratectomy may be utilized as a keratoplasty-sparing intervention for superficial corneal scarring.

However, if uncertain, the diagnosis of herpes labialis can be made by viral culture, polymerase chain reaction, serology, direct fluorescent antibody testing, or Tzanck test. The vesicle should be unroofed with a scalpel or sterile needle, and a swab should be used to soak up the fluid and to scrape the base.
Treatment was initiated with topical prednisolone acetate 1.0% QID, while maintaining antiviral and prophylactic antibiotic coverage. There are unsubstantiated concerns that this procedure may be associated with activation of immunological stromal keratitis; in any case, perioperative use of full antiviral therapy followed by a prolonged prophylactic course obviates this issue.
This condition may lead to permanent scarring with associated vision loss and need for corneal transplant.
Other nonoral herpes simplex virus type 1 infections include herpetic keratitis, herpetic whitlow, herpes gladiatorum, and herpetic sycosis of the beard area.


The swab should be sent in special viral transport media directly to the laboratory (or placed on ice if transport will be delayed).
There was no peripheral stromal vascularization, perineuritis, endothelial or anterior chamber inflammation.
Although most practitioners prefer a short course of therapy, we treat our patients for a total of 14 to 21 days to ensure complete eradication of replicating organisms. For deeper stromal scarring, penetrating or deep anterior lamellar keratoplasty are the procedures of choice. The differential diagnosis of nongenital herpes simplex virus infection includes aphthous ulcers, acute paronychia, varicellazoster virus infection, herpangina, herpes gestationis (pemphigoid gestationis), pemphigus vulgaris, and BehA┬žet syndrome. There were more aborted lesions in the valacyclovirclobetasol group compared with the placebo-placebo group (50 versus 15.8 percent). After successful treatment, therapy can be discontinued without tapering, unless long-term prophylaxis is used (see below; antiviral prophylaxis).
The prognosis for graft survival has improved dramatically over the last quarter century since the introduction of oral antiviral prophylaxis. Oral acyclovir suspension is an effective treatment for children with primary herpetic gingivostomatitis. Usatine, MDFigure 2.Primary herpetic gingivostomatitis caused by herpes simplex virus type 1 shown in (A) a four-year-old girl with lower lip ulcers and crusting on the upper lip, and (B) a two-year-old girl with ulcers on the lower lip and tongue. Direct fluorescent antibody testing may be performed from air-dried specimens, and can detect 80 percent of true HSV-positive cases compared with culture results.10 Immunoglobulin G antibodies that are type-specific to HSV develop the first several weeks after infection and persist indefinitely. This can be attributed to reduced recurrence of herpetic epithelial keratitis, a condition that is frequently associated with acute endothelial rejection episodes. Oral acyclovir, valacyclovir, and famciclovir are effective in treating acute recurrence of herpes labialis (cold sores). A Tzanck test is difficult to perform correctly without specific training in its use, but it may be done in the office setting by scraping the floor of the herpetic vesicle, staining the specimen, and looking for multinucleated giant cells. Neither ISK nor NIK is self-limited and failure to provide appropriate pharmaceutical intervention will result in progressive corneal scarring and visual impairment. In the unusual situation of corneal endothelial decompensation due to neglected or recalcitrant endothelial keratitis, endothelial keratoplasty can be performed if stromal disease has not been present.
Recurrences of herpes labialis may be diminished with daily oral acyclovir or valacyclovir. Usatine, MDIn recurrent herpes labialis, symptoms of tingling, pain, paresthesias, itching, and burning precede the lesions in 60 percent of persons.5 The lesions then appear as clusters of vesicles on the lip or vermilion border (Figure 1). They applied penciclovir cream or placebo within one hour of the first sign or symptom of a recurrence, and then every two hours while awake for four days. Topical acyclovir, penciclovir, and docosanol are optional treatments for recurrent herpes labialis, but they are less effective than oral treatment. Resolution of symptoms occurred more rapidly in the penciclovir group regardless of whether the medication was applied in the early or late stage. Nongenital herpes simplex virus type 1 (HSV-1) is a common infection that most often involves the oral mucosa or lips (herpes labialis). The primary oral infection may range from asymptomatic to very painful, leading to poor oral intake and dehydration.
Usatine, MDFigure 3.(A) Ulcers that form after the vesicles break, as shown in an adult women with herpes labialis. Common symptoms are eye pain, light sensitivity, and discharge with gritty sensation in the eye. Fluorescein stain with a ultraviolet light may show a classic dendritic ulcer on the cornea (Figure 47). Usatine, MDHerpetic whitlow is a vesicular lesion found on the hands or digits (Figures 68 and 7). It occurs in children who suck their thumbs or medical and dental workers exposed to HSV-1 while not wearing gloves. Herpes gladiatorum is often seen in athletes who wrestle, which may put them in close physical contact with an infected person. Vesicular eruptions are often seen on the torso, but can occur in any location where skin-to-skin contact has occurred. Herpetic sycosis is a follicular infection with HSV that causes vesiculopapular lesions in the beard area. Usatine, MDHSV infection is one of the most common causes of erythema multiforme (Figure 8), which some patients have with a recurrent HSV infection.
