1/57. Typical varicella zoster (ophthalmicus) in an hiv-infected person.A typical varicella zoster (ophthalmicus) in an incidentally hiv-infected person is reported in a young man. It was characterized by tense, grouped, vesiculobullous eruptions on a brick-red base. The diagnosis was substantiated by demonstration of swollen epidermal (balloon) cells with a nucleus/several nuclei containing inclusion bodies. Reticular degeneration was apparent.- - - - - - - - - - ranking = 1keywords = varicella (Clic here for more details about this article) |
2/57. zoster sine herpete with bilateral ocular involvement.PURPOSE: To report a case of zoster sine herpete with bilateral ocular involvement. METHOD: Case report. RESULTS: A 65-year-old man showed bilateral iridocyclitis with sectoral iris atrophy and elevated intraocular pressure unresponsive to steroid treatment. No cutaneous eruption was manifest on the forehead. A target region of varicella-zoster virus dna sequence was amplified from the aqueous sample from the left eye by polymerase chain reaction. Bilateral iridocyclitis resolved promptly after initiation of systemic and topical acyclovir treatment. Secondary glaucoma was well controlled by bilateral trabeculectomy. CONCLUSIONS: zoster sine herpete should be considered and polymerase chain reaction performed on an aqueous sample to detect varicella-zoster virus dna for rapid diagnosis whenever anterior uveitis accompanies the characteristic iris atrophy, even in the case of bilateral involvement.- - - - - - - - - - ranking = 0.4keywords = varicella (Clic here for more details about this article) |
3/57. Acute retinal necrosis following contralateral herpes zoster ophthalmicus.BACKGROUND: A case report of contralateral acute retinal necrosis (ARN) following herpes zoster ophthalmicus. CASE: A 61-year-old male patient developed iridocyclitis and well-demarcated creamy-white retinal lesions at the nasal periphery in the right eye 1 month after herpes zoster ophthalmicus in the left eye. The patient had undergone surgery for primary lung cancer, and had subsequent intracranial metastasis of the tumor. OBSERVATIONS: The clinical diagnosis of ARN was supported by polymerase chain reaction investigation of the aqueous humor resulting in positive for varicella-zoster virus. Retinal lesions disappeared after systemic treatment with acyclovir, corticosteroids, and acetylsalicylate. No retinal detachment developed. CONCLUSIONS: We propose a careful ophthalmic follow-up for herpes zoster ophthalmicus patients because of the possibility of acute retinal necrosis developing in the contralateral eye.- - - - - - - - - - ranking = 0.2keywords = varicella (Clic here for more details about this article) |
4/57. optic chiasm, optic nerve, and retinal involvement secondary to varicella-zoster virus.Immunocompromised patients are known to be at risk for varicella-zoster virus reactivation, often in atypical manners. We describe a 30-year-old man with simultaneous involvement of the retina, optic chiasm, and optic nerve with varicella-zoster virus who had a bitemporal visual field defect.- - - - - - - - - - ranking = 1.2keywords = varicella (Clic here for more details about this article) |
5/57. Varicella-zoster viral antigen identified in iridocyclitis patient.BACKGROUND: The varicella-zoster virus (VZV) antigen has not been identified immunohistologically in iridocyclitis due to VZV. CASE: A 65-year-old woman diagnosed with iridocyclitis and secondary glaucoma underwent trabeculectomy. Samples of aqueous humor and juxtacanalicular and iris tissue were obtained for immunohistological and polymerase chain reaction (PCR) study. OBSERVATIONS: Slit-lamp microscopy revealed ciliary injection, corneal epithelial edema, mutton fat precipitates, flare, cells, and progressive iris atrophy in the right eye. Subsequently, scant eruptions on her right upper eyelid appeared and disappeared within a week. Although a diagnostic increase in the complement fixation antibody titer to VZV was not observed, we started medical treatment for VZV, on suspicion of iridocyclitis due to VZV. Despite medical treatment, the ratio of peripheral anterior synechia was greater than 60% and iris atrophy progressed in parallel. The intraocular pressure in the right eye remained above 30 mm Hg at 6 months after the first visit, so trabeculectomy was performed. VZV-specific dna was detected in the aqueous humor by the PCR study. Immunohistological examination demonstrated numerous VZV antigen-positive cells in the iris stroma, in particular, vascular endothelial cells. CONCLUSION: To our knowledge, this is the first report of the detection of VZV antigen in the iris of an iridocyclitis patient.- - - - - - - - - - ranking = 0.2keywords = varicella (Clic here for more details about this article) |
6/57. Aseptic meningitis and optic neuritis preceding varicella-zoster progressive outer retinal necrosis in a patient with AIDS.Varicella-Zoster Virus (VZV) is the second most common ocular pathogen in patients with hiv infection. VZV retinitis is estimated to occur in 0.6% of patients with hiv infection and may occur in one of two clinical syndromes. The first is the acute retinal necrosis syndrome, which also may be seen in immunocompetent hosts. The second clinical syndrome occurs in patients with CD4 cell counts typically < 50 x 10(6)/l and is termed progressive outer retinal necrosis. VZV retinitis has been reported to occur simultaneously with other VZV central nervous system manifestations such as encephalitis and myelitis in hiv-infected patients. In addition, VZV retrobulbar optic neuritis heralding VZV retinitis has recently been described in hiv-infected patients who had suffered a recent episode of dermatomal herpes zoster. Herein we report the case of an hiv-infected individual who presented with VZV meningitis and retrobulbar optic neuritis that preceded the onset of progressive outer retinal necrosis. We also review of the literature of seven additional reported cases of retrobulbar optic neuritis preceding the onset of VZV retinitis.- - - - - - - - - - ranking = 0.8keywords = varicella (Clic here for more details about this article) |
7/57. herpes zoster ophthalmicus: how is it identified and treated?PURPOSE: To describe herpes zoster ophthalmicus in relation to the anatomy, pathophysiology, course, diagnostic considerations, and management for the primary care provider. DATA SOURCES: Actual case study supplemented with an extensive review of current scientific and psychosocial literature. CONCLUSIONS: herpes zoster ophthalmicus (HZO) is an extension of a herpes zoster (HZ) infection involving the fifth cranial (trigeminal) nerve, which results from the reactivation of a latent varicella virus among individuals who had contracted a varicella infection sometime within their lifespan. IMPLICATIONS FOR PRACTICE: Due to the vague presenting symptomology of HZO, many patients may be misdiagnosed lessening the chance for prompt diagnosis and therapeutic intervention. Educational awareness, listening to psychosocial concerns of the patients, and immediate referral can decrease potential chronic side effects of the disorder.- - - - - - - - - - ranking = 0.4keywords = varicella (Clic here for more details about this article) |
8/57. Corneal epithelial keratitis in herpes zoster ophthalmicus: "delayed" and "sine herpete". A non-contact photomicrographic in vivo study in the human cornea.PURPOSE: To investigate the origin of corneal epithelial keratitis occurring without accompanying herpes zoster ophthalmicus (HZO) cutaneous rash. methods: Corneal epithelial lesions in seven patients (four with a history of classical HZO with cutaneous rash, one of herpes zoster oticus, and two with no history of herpes zoster, were examined with the slit lamp and photographed by non-contact in vivo photomicrography. The findings were compared with lesions in classical acute HZO. polymerase chain reaction (PCR) was done in three patients. RESULTS: Slit lamp appearance, morphology at higher magnification, and kinetics of the lesions were indistinguishable from classical acute HZO. PCR was positive for varicella-zoster virus dna in all three samples. CONCLUSIONS: The findings strongly suggest that HZO typical corneal epithelial lesions occurring in the absence of cutaneous rash are in fact recurrent episodes of virus shedding.- - - - - - - - - - ranking = 0.2keywords = varicella (Clic here for more details about this article) |
9/57. herpes zoster ophthalmicus.BACKGROUND: We examined the literature for the latest information on diagnosis and management of herpes zoster, and compiled a representative database. methods: Using search engines and library resources, we reviewed pathology, epidemiology, pathophysiology, differential diagnosis, and management. RESULTS: The varicella zoster virus is a member of the herpes virus family that produces an infection through direct contact with active skin lesions or airborne droplets. The infection resides latent in the trigeminal ganglion until reactivated, often affecting the sensory nerve, skin, eye, and adnexa. CONCLUSION: The varicella zoster virus has the potential to severely disrupt the structures of the eye. patients less than 50 years of age should be referred for systemic workup to rule out an immunocompromised state. In general, management is often palliative and/or geared toward specific sequelae.- - - - - - - - - - ranking = 0.4keywords = varicella (Clic here for more details about this article) |
10/57. Unilateral varicella zoster virus ophthalmicus and contralateral acute retinal necrosis.We report two patients who developed varicella zoster virus (VZV) ophthalmicus complicated by ipsilateral keratouveitis, and within 4 weeks developed acute retinal necrosis (ARN) in the contralateral eye. The ipsilateral retina was spared in each case. One patient had systemic lupus erythematosus (SLE) and the other Hodgkin's disease. Both patients were in remission at the time of presentation.- - - - - - - - - - ranking = 1keywords = varicella (Clic here for more details about this article) |
