1/8. Herpesvirus hominis encephalitis and retinitis.

    A previously healthy 44-year-old man died three weeks after the simultaneous onset of encephalitis and retinitis. Fundus changes were bilateral and included papillitis, rapidly progressive central retinal vein obstruction, and massive exudative retinal detachment. A 16-fold rise in herpesvirus hominis antibodies occured between the 10th and 20th days of illness. At autopsy, the brain showed changes characteristic of herpetic encephalitis, and cultures of the brain yielded Herpesvirus hominis type I. intranuclear inclusion bodies typical of those produced by Herpesvirus were found by light microscopy in brain, optic nerves, retina, and choroid. Herpesvirus particles were found by electron microscopy in brain, optic nerve, and retina.

2/8. Ocular histopathologic findings in a case of human herpes B virus infection.

    A 37-year-old male laboratory technician who sustained a cutaneous penetrating wound from a rhesus monkey developed a progressive ascending encephalomyelitis due to culture-proven herpes B virus (Herpesvirus simiae) infection. He died 6 weeks after his injury despite acyclovir and ganciclovir treatment that was initiated after central nervous system symptoms developed. Histopathological examination of the patient's left eye revealed a multifocal necrotizing retinitis associated with a vitritis, optic neuritis, and prominent panuveitis. Herpes-type virus was identified in the involved retina by electron microscopy. Postmortem vitreous cultures taken from both eyes and retinal cultures taken from the right eye were positive for herpes B virus. Herpes B virus produces infection and destruction of retinal tissues similar to other herpesviruses. To our knowledge, this case represents the first histopathologic demonstration of herpes B virus infection in a human eye.

3/8. Bilateral acute retinal necrosis (BARN). Identification of the presumed infectious agent.

    We describe histopathologic features of an enucleated eye of a patient suffering bilateral acute retinal necrosis (BARN). Retinal tissue was found focally degenerated, and the choroid massively enlarged by lymphoid-like agranular cells. An association of the disease with a viral infection could be demonstrated by (a) the presence of virus particles of the herpesvirus type in retinal tissue, (b) the transmission of the infected principle to human embryo fibroblast cultures, and (c) the visualization of CMV-antigens by immunofluorescence microscopy in such infected cultures. Slow growth of the virus in vitro and the presence of CMV-antigens after infection indicate that the herpesvirus involved in BARN was of the type CMV. On the basis of these findings we propose a guideline for therapy.

4/8. Syphilitic retinitis. A cause of necrotizing retinitis.

    A healthy-appearing male patient presented with signs of unilateral fibrinous iritis, necrotizing retinitis, retinal vasculitis, and vitritis, suggestive of a herpesvirus retinitis or acute retinal necrosis syndrome (ARN). The patient, an active homosexual, withheld the details of his sexual history, portraying himself as exclusively heterosexual. With the exception of a positive VDRL and FTA-ABS, the workup was negative. Examination of the cerebrospinal fluid confirmed the presence of neurosyphilis. The patient was successfully treated with intravenous penicillin, which resulted in a complete visual recovery. Syphilitic retinitis must be considered in evaluating patients with necrotizing retinitis.

5/8. Progressive zonal outer retinitis.

    We examined an immunocompetent patient with uniocular acute progressive outer retinitis. The retinitis was curvilinear in shape, showed progressive enlargement, and appeared to be altered by treatment with intravenous acyclovir. When regressed, the affected area of retina appeared atrophic and, at one-year follow-up, demonstrated intraretinal pigment migration with retinal pigment epithelial atrophy and atrophy of the choriocapillaris. Although visual acuity was unaffected, a dense scotoma was recorded on field testing. The response to acyclovir implicates the herpesvirus family, and acyclovir or another antiherpetic agent should be considered for such cases.

6/8. Varicella-zoster virus retinitis in a patient with aids-related complex: case report and brief review of the acute retinal necrosis syndrome.

    retinitis reminiscent of the acute retinal necrosis syndrome was recognized in a patient with aids-related complex after he had experienced several episodes of a sacral, dermatomic zosteriform eruption. Varicella-zoster virus (VZV) was subsequently recovered from cell culture of retinal tissue. The literature on VZV retinitis, including that on acute retinal necrosis, is reviewed. Dissemination of VZV infection in AIDS is also reviewed. Features that differentiate the findings and course of VZV retinitis in patients with AIDS from those in otherwise healthy adults are noted and related to potentially different pathogenic mechanisms. This unusual and recently recognized complication of herpesvirus infection may be promoted by AIDS-related immunosuppression. Acute retinal necrosis and other more-recently described forms of VZV retinitis, which have primarily been subjects of the ophthalmologic literature, merit the attention of clinicians and investigators of infectious diseases.

7/8. central nervous system herpesvirus infection in systemic lupus erythematosus: diagnosis by endoretinal biopsy.

    A 31-year-old woman with systemic lupus erythematosus (SLE) developed meningoencephalitis, followed by transverse myelitis. The clinical picture was otherwise not consistent with a lupus flare. Extensive diagnostic evaluation was unrevealing. Acute visual loss ensued, associated with an unusual pattern of retinitis. Endoretinal biopsy established the diagnosis of herpesvirus infection. Reinstitution of antiviral therapy, and optic nerve sheath decompression, led to resolution of neurologic deficits and partial return of vision. Our report is the first that describes a patient with SLE with herpes meningoencephalitis, transverse myelitis, and rapidly progressive outer retinal necrosis, diagnosed antemortem by endoretinal biopsy, and successfully treated with acyclovir and optic nerve fenestration.

8/8. Retinal perivasculitis in an immunocompetent patient with systemic herpes simplex infection.

    PURPOSE: To describe a case of retinal perivasculitis in an immunocompetent patient with systemic herpes simplex infection. methods: polymerase chain reaction amplifications were performed for aqueous and blood samples using primers specific for the following members of the herpesvirus family: cytomegalovirus, Epstein-Barr virus, herpes simplex virus (types 1 and 2), and varicella-zoster virus. The patient was placed on intravenous acyclovir and systemic corticosteroids. RESULTS: A positive polymerase chain reaction signal was found only for herpes simplex virus type 1. Vision in the left eye improved from light perception to 20/25, and signs of retinal perivasculitis resolved. CONCLUSION: The use of molecular diagnostic modalities in clinical practice may aid in determining infectious etiologies in patients with atypical clinical manifestations.
