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 is reactivation of a varicella-zoster virus infection (shinglessee also Herpes Zoster) involving the eye.
Common features of herpes zoster ophthalmicus are as follows: Classic symptoms and lesions of herpes zoster. Herpes zoster ophthalmicus involves the orbit of the eye and occurs in approximately 10 to 25 of cases. Other complications of herpes zoster includeophthalmic involvement with acute or chronic ocular sequelae (herpes zoster ophthalmicus) ; Herpes zoster is an infection resulting from reactivation of the varicella-zoster virus (VZV) that affects peripheral or cranial nerves and usually occurs years after primary infection with the varicella (chickenpox) virus or receipt of the live, attenuated varicella vaccine. Valacyclovir (Valtrex) has higher bioavail-ability and has been shown to be equally safe and effective for the treatment of herpes zoster at a dosage of 1, 000 mg three times daily for seven or 14 days. Successful treatment with intravenous acyclovir has been reported in numerous cases, and this has become the recommended treatment for patients at high risk for acquiring HIV. One out of every 100 individuals will contract herpes zoster ophthalmicus during his or her lifetime. 12 Upon presentation of herpes zoster ophthalmicus, it is critical to initiate systemic treatment with oral antiviral agents (see Oral Dosing for Herpes Zoster, above).
Of 94 patients with acute herpes zoster ophthalmicus who were seen during a six-year period, 61 had corneal involvement. Complications in immunocompromised individuals with herpes zoster may be reduced with intravenous acyclovir. All patients with acute herpes zoster ophthalmicus should receive antiviral therapy with the goal of preventing ocular complications. Most patients with herpes zoster ophthalmicus present with a periorbital vesicular rash distributed according to the affected dermatome. Eye problems: Shingles that involve the eye are called ocular shingles or herpes zoster ophthalmicus. In contrast, primary varicella zoster virus infection causes the common childhood illness varicella (chickenpox) which usually manifests as a widespread vesicular rash. The corneal complications in the order of chronological clinical occurrence were punctate epithelial keratitis in 51, early pseudodendrites in 51, anterior stromal infiltrates in 41, sclerokeratitis in 1, kerato-uveitisendothelitis in 34, serpiginous ulceration in 7, delayed corneal mucous plaques in 13, disciform keratitis in 10, neurotrophic keratitis in 25, and exposure keratitis in 11.


Synonyms: herpes zoster and varicella zoster Shingles is caused by the human herpesvirus-3 (HHV-3). Neurologic complications of herpes zoster, including chronic encephalitis, occur with increased frequency in AIDS patients.
Of 86 patients with herpes zoster ophthalmicus seen at the Mayo Clinic, Rochester, Minn, from 1975 to 1980, 61 had some form of ocular involvement. A minority of patients may also develop conjunctivitis, keratitis, uveitis, and ocular cranial-nerve palsies. Treatment includes topical capsaicin cream, over-the-counter analgesics, tricyclic antidepressants, and anticonvulsants.18Cranial nerve palsies involving the third (most common), fourth, and sixth nerves may occur rarely (Figure 5). Herpes zoster is a common infection caused by the human herpesvirus 3, the same virus that causes varicella (i. Clinical Manifestations of Herpes Zoster Ophthalmicus (includes Images) Yanoff: Ophthalmology, 4th ed. Herpes zoster (shingles) is a painful rash caused by the same virus that causes chickenpox.
Complications of herpes zoster in immunocompetent patients include encephalitis, myelitis, cranial- and peripheral-nerve palsies, and a syndrome of delayed contralateral hemiparesis.
Permanent sequelae of ophthalmic zoster infection may include chronic ocular inflammation, loss of vision, and debilitating pain.
The earliest symptoms of herpes zoster, which include headache, fever, and malaise, are nonspecific, and may result in an incorrect diagnosis. All patients with zoster ophthalmicus should receive antiviral therapy even if it is delayed beyond 72 hours. 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.
Most cases of herpes zoster ophthalmicus present within a few days of skin lesions appearing, says Jay Pepose, MD, PhD, medical director of the Pepose Vision Institute and president of the Lifelong Vision Institute, St. Preventing herpes zoster with vaccination is the best way to avoid postherpetic neuralgia and other complications. 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. Sy, A population-based study of the incidence and complication rates of herpes zoster before zoster vaccine introduction, Mayo Clinic Proceedings, vol. Below is a list of common medications used to treat or reduce the symptoms of Herpes Zoster Ophthalmicus.


A form of herpes zoster in which the virus invades the gasserian ganglion, causing pain and skin eruptions along the ophthalmic branch of the fifth cranial nerve. 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. We found a similar age-specific incidence of herpes zoster in North America, Europe and Asia-Pacific; however, there is a scarcity of research from other regions.
Herpes zoster ophthalmicus: comparison of disease in patients 60 years and older versus younger than 60 years. Corneal complications occur in approximately 65 percent of cases of herpes zoster ophthalmicus.7Epithelial Keratitis.
The earliest corneal finding is punctate epithelial keratitis.10 On slit lamp examination, this appears as multiple, focal, swollen lesions that stain with rose bengal or fluorescein dye.
Herpes zoster ophthalmicus affecting the trigeminal nerve (the forehead) Herpes zoster arising after a surgical operation Close-up of blisters Image supplied by Dr T Evans Herpes zoster. Herpes zoster ophthalmicus occurs when shingles affects the ophthalmic branch of the trigeminal nerve (the 5th cranial nerve).
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).
Most of the infiltrates lie directly beneath pre-existing dendrites or areas of punctate epithelial keratitis. This later stage of stromal keratitis is relatively uncommon and typically develops three to four months after the initial acute episode, but development can range from one month to many years later.7 It is usually central and preceded by anterior stromal keratitis. The keratitis may present as a lesion consisting of a localized area of inflammation affecting all levels of the stroma, or as peripheral infiltrates that may have a surrounding immune ring. A chronic relapsing course is not unusual, especially without timely and adequate treatment.
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. As with stromal keratitis, the course of disease may be prolonged, especially without timely, adequate treatment. 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.
