A retrospective study of the clinical presentation and outcome of herpes zoster in a tertiary dermatology outpatient referral clinic. Herpes zoster ophthalmicus in patients at risk for the acquired immune deficiency syndrome (AIDS). Natural history of herpes zoster ophthalmicus: predictors of postherpetic neuralgia and ocular involvement. Varicella zoster virus retrobulbar optic neuritis preceding retinitis in patients with acquired immune deficiency syndrome. Valaciclovir compared with acyclovir for improved therapy for herpes zoster in immunocompetent adults. Comparison of the efficacy and safety of valaciclovir and acyclovir for the treatment of herpes zoster ophthalmicus.
Herpes zoster ophthalmicus (HZO) involves the ophthalmic branch, which is the first division of the trigeminal nerve. Besides pain and rash in the affected ophthalmic dermatome other acute stage ocular involvement includes swelling and reddening of eye, ptosis with some even developing blepharitis and vesicular lesions which mostly resolves with scarring. Beside, commonly used antivirals agents for herpes zoster like acyclovir, Famciclovir, valacyclovir, and brivudin, immediate use of a single intravitreal injection of foscarnet is usually recommended to further stop viral replication and progression to retinitis especially in case of ARN or PORN [4]. Oral antivirals are the cornerstone of therapy for ocular herpetic disease, but careful diagnosis and judicious comanagement play essential roles as well. Herpes simplex is the leading cause of infectious corneal blindness in the United States.4 In its epithelial form, dendritic keratitis is the most common presentation to the primary care optometrist.
Secondarily, the clinician can be tipped to the possibility of prior herpes infection if there exists unexplained corneal scarring, corneal hypoesthesia or iris atrophy. Although poorly referenced in the literature, some practitioners believe that it’s beneficial to defer treatment the first time a patient has an episode of systemic herpes simplex. In interviewing local specialists in pediatric ophthalmology and infectious disease, I found that the no-treatment notion is disputed as dangerous because the possible manifestations of disseminated herpes outweigh the risk of a suppressed immune response.
At least one study has reported favorable results when treating herpes simplex keratitis in patients who concurrently suffer from dry eye.9 The combination of punctal cautery and Restasis (cyclosporine, Allergan) therapy reduced the recurrence rate of herpes simplex stromal keratitis in a sample of 42 patients. More importantly, it should prove reassuring that Restasis can indeed be used in patients who have suffered herpes simplex keratitis, albeit with close monitoring.
However, topical steroid use is a required element in the treatment of several forms of ocular herpes simplex. Note that the Physician’s Desk Reference indicates higher oral antiviral doses for herpes zoster than for herpes simplex.


According to several studies ophthalmic division of the trigeminal nerve are involved in about 10-25% of reported cases of herpes zoster cases.
Pseudodendrites can be caused by contact lenses and their solutions, trauma, dry eye, and other infections, especially herpes zoster. This study is interesting because it suggests that dry eye is a stressor that may contribute to stromal keratitis in the herpes patient. Since its introduction, our practice has successfully prescribed Restasis for dry eye patients who have a history of herpes simplex keratitis, provided that there are no active epithelial lesions.
In addition, opposition to optometric drug laws had painted steroid use as inappropriate, with herpetic exacerbation as the feared endpoint.
Visual outcome in her-pes simplex virus and varicella zoster virus uveitis: a clinical evaluation and comparison. Most patients with herpes zoster ophthalmicus present with a periorbital vesicular rash distributed according to the affected dermatome.
Zoster ophthalmicus is estimated to occur approximately in 10% of zoster patients under the age of 10 years and about 30% of patients aged 80-year-old and older. Eyelid and ocular adnexal involvement is most commonly seen in patients with herpes zoster ophthalmicus followed by conjunctivitis, corneal complication, uveitis and PHN. This course explains how to identify and treat cases of ocular herpetic disease, and when to refer patients for further care. Herpetic iritis is also treated with aggressive steroid use, including hourly prednisolone acetate and cycloplegia as cornerstone therapies. Study shows that, Brivudin [5] had an 11% lower PHN rate than acyclovir and was as seen as effective as famciclovir to reduce zoster associated pain.
Similarly, Posner-Schlossman syndrome, with its elevated IOP and mild anterior chamber reaction, benefits from steroid treatment even though it may be herpetic in etiology. Permanent sequelae of ophthalmic zoster infection may include chronic ocular inflammation, loss of vision, and debilitating pain.
The rash of ophthalmic zoster may extend from the level of the eye to the vertex of the skull and does not cross the midline of the forehead. Involvement of the nasociliary branch of the ophthalmic nerve which is evidenced by a zosteric rash on the tip and side of the nose (Hutchinson’s sign) is seen in about one-third of patients HZO and is usually accompanied by ocular symptoms. VZV-DNA was detected in conjunctival swabs of some cases of acute ophthalmic zoster disease [2].
Optic neuritis has been noted in about one in 400 cases and may precede retinal disease or follow acute herpes zoster ophthalmicus infection (Figure 6).17,19,20The rightsholder did not grant rights to reproduce this item in electronic media.


Oral acyclovir may be beneficial as an adjunct to topical antivirals and topical steroids in severe cases of zoster keratouveitis.
Thus, when ophthalmic zoster affects the side and the tip of the nose, careful attention must be given to the condition of the eye and immediate ophthalmologic consultation is necessary in order to prevent complications of the eye and central nerve system Zoster Infection. All the patients who develop herpes zoster adjacent to eye do not develop ocular involvement, but in those that do, there can be a wide variety of manifestations. Timely diagnosis and management of herpes zoster ophthalmicus, with referral to an ophthalmologist when ophthalmic involvement is present, are critical in limiting visual morbidity. It is a member of the same family (Herpesviridae) as herpes simplex virus, Epstein-Barr virus, and cytomegalovirus. Reactivation of the latent virus in neurosensory ganglia produces the characteristic manifestations of herpes zoster, commonly known as shingles. A vast majority of patients will have vesicular lesions on the eyelids that resolve with minimal scarring.Conjunctivitis is one of the most common complications of herpes zoster ophthalmicus.
Normal aging, poor nutrition, and immunocompromised status correlate with outbreaks of herpes zoster, and certain factors such as physical or emotional stress and fatigue may precipitate an episode.Herpes zoster ophthalmicus occurs when reactivation of the latent virus in the trigeminal ganglia involves the ophthalmic division of the nerve. Corneal complications occur in approximately 65 percent of cases of herpes zoster ophthalmicus.7Epithelial Keratitis. Punctate epithelial keratitis may present as early as one or two days after the initial skin rash, while dendrites often present at four to six days but can appear many weeks later.11Herpes zoster virus dendrites appear as elevated plaques and consist of swollen epithelial cells. The earliest finding of corneal stromal involvement presents during the second week of disease, occurring in 25 to 30 percent of patients with herpes zoster ophthalmicus.13 The condition, known as anterior stromal keratitis or nummular keratitis, is characterized by multiple fine granular infiltrates in the anterior corneal stroma below the epithelial layer (Figure 3).
Neurotrophic keratitis is the end result of decreased corneal sensation from herpes zoster virus-mediated destruction, including susceptibility to mechanical trauma, decreased lacrimation, and delayed epithelial healing.7 Corneal thinning is a serious complication that may lead to corneal perforation.
Using preservative-free lubricating drops and ointment can prevent the development of epithelial defects.UVEITISAnterior uveitis, which is diagnosed by slit lamp examination, refers to inflammation of the iris and ciliary body and occurs frequently with herpes zoster ophthalmicus. Both conditions may be accompanied by localized stromal keratitis.ACUTE RETINAL NECROSIS AND PROGRESSIVE OUTER RETINAL NECROSIS SYNDROMESHerpes zoster virus is considered the offending agent in most cases of acute retinal necrosis and progressive outer retinal necrosis syndromes.
