Abstract
The eye is a common site for complications of human immunodeficiency virus (HIV) infection. Although cytomegalovirus retinitis remains the most prevalent of the blinding ocular disorders that can occur in individuals with the acquired immunodeficiency syndrome (AIDS), several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae. Some of these entities, such as Kaposi sarcoma, were well described, but uncommon, before the HIV epidemic. Others, like microsporidial keratoconjunctivitis, have presentations that differ between affected individuals with HIV disease and those from the general population who are immunocompetent. The treatment of many of these diseases is challenging because of host immunodeficiency. Survival after the diagnosis of AIDS has increased among individuals with HIV disease because of more effective antiretroviral therapies and improved prophylaxis against, and treatment of, opportunistic infections. This longer survival may lead to an increased prevalence of anterior segment and external ocular disorders. In addition, the evaluation and management of disorders such as blepharitis and dry eye, which were previously overshadowed by more severe, blinding disorders, may demand increased attention, as the general health of this population improves. Not all individuals infected with HIV receive potent antiretroviral therapy, however, because of socioeconomic or other factors, and others will be intolerant of these drugs or experience drug failure. Ophthalmologists must, therefore, still be aware of the ocular findings that develop in the setting of severe immunosuppression. This article reviews the spectrum of HIV-associated anterior segment and external ocular disorders, with recommendations for their evaluation and management.

Abstract
The diagnosis of cytomegalovirus retinitis (CMV-R) is difficult and usually based on clinical criteria or invasive diagnostic procedures. The purpose of this study was to investigate a possible association between CMV-R and specific anti-CMV antibodies in tears. Paired tear and serum samples were obtained from 96 individuals, which included 20 children with congenital CMV infection and chorioretinitis, 56 adults with retinitis with clinical signs suggestive of viral infection, and 20 healthy control subjects, and were tested for CMV antibodies using ELISA. The prevalence of anti-CMV antibodies in tears was found to be 80% (16/20) in children, 35% (20/56) in adults, and 5% (1/20) in control subjects. Furthermore, high antibody levels were detected in 35% (7/20) of children and 10.7% (6/56) of adults with retinitis, and were not found in control subjects. There was a strong association between high tear levels of anti-CMV antibodies and active ocular infection. No correlations were found between tear and serum antibodies. ELISA sensitivity was 80% and specificity 95%. Further studies are needed to compare the tear and intraocular levels of CMV-specific antibodies in patients with retinitis to find out if CMV antibody testing in tear fluid could substitute for more invasive diagnostic procedures.

Abstract
This report studies the accuracy of conjunctival swab polymerase chain reaction (CS-PCR) for the diagnosis of human cytomegalovirus retinitis (HCMV) in AIDS patients. PCR and virus culture were used for the detection of HCMV in conjunctival swab, serum, and urine specimens from 38 AIDS patients between April 1996 and April 1998. The clinical utility of the identification of HCMV retinitis by these 6 different methods was demonstrated by their prediction power to estimate AIDS patients at risk of contracting HCMV retinitis. The sensitivity, specificity, positive predictive value, and negative predictive value of CS-PCR for the detection of HCMV retinitis were 91.5%, 80.9%, 60.8%, and 92.7%, respectively; for serum PCR were 74.3%, 81.7%, 57.2%, and 90.3%; for urine PCR were 100%, 17.3%, 20.4%, and 100%; for conjunctival swab culture were 22.7%, 100%, 100%, and 86%; for serum culture were 27.3%, 98.1%, 75%, and 86.4%; and for urine culture were 90.9%, 44.2%, 25.6%, and 95.8%.

Abstract
Viruses are one of the most common causes of infections involving the posterior segment of the eye. Such infections can occur either on a congenital or an acquired basis, and may affect primarily the retina or the choroid. Congenital cytomegalovirus (CMV) and rubella infections may result in retinitis. CMV retinitis is also the most common cause of acquired viral retinitis, primarily because of the acquired immunodeficiency syndrome (AIDS). Other types of viral retinitis, such as those caused by herpes simplex or herpes zoster, can occur in immunocompromised or immunocompetent individuals. Retinitis or choroiditis caused by viruses such as measles, influenza, Epstein-Barr virus, and Rift Valley fever virus, typically occurs subsequent to an acute viral systemic illness. The systemic and ocular manifestations, as well as the histopathology, laboratory tests, differential diagnoses, and treatment regimens for each of the individual viruses are discussed in detail.

Abstract
Six patients (11 eyes) with virologically confirmed cytomegalovirus (CMV) retinitis involving the posterior pole of the eye were treated with a new drug, ganciclovir. Treatment with intravenous ganciclovir consistently halted progression of retinitis and produced improvement in measures of visual function. However, within three weeks after cessation of therapy renewed CMV activity and worsening of visual function were observed in most cases. Maintenance therapy with ganciclovir extended the period of remission from CMV retinitis.

Abstract
To investigate the risk of cytomegalovirus transmission by corneal transplantation, we quantitated anticytomegalovirus IgG levels of donor, preoperative, and postoperative serum samples. Of 118 patients, 79 (67%) were seropositive preoperatively. Twenty-five patients who were seronegative preoperatively received a graft from a positive donor and two (8%) seroconverted. Eleven patients who were seronegative preoperatively received a graft from a negative donor and one (9%) seroconverted. None of the patients who seroconverted had a febrile illness and all three grafts were clear.

Abstract
A child with bilateral cytomegalovirus (CMV) retinitis, vitritis, and exudative retinal detachments, who was in remission from stage IV neuroblastoma and status post-chemotherapy and autologous bone marrow transplantation, was treated with ganciclovir. The drug is a new acyclic nucleoside antiviral drug with potent antiCMV activity. There was bilateral retinal reattachment, clearing of vitritis and regression of retinal exudates and hemorrhages, with concomitant resolution of viral shedding in urine and blood, on ganciclovir 7.5 mg/kg per day. There was recurrence of exudative detachments, vitritis and retinitis when the dose was reduced to 2.5 mg/kg per day, and regression of these findings when the dose was again increased to 7.5 mg/kg per day. Despite continued therapy at this dose, a relapse occurred. When the dose of drug was doubled to 15 mg/kg per day, there initially was a partial therapeutic response, followed by a subsequent relapse. No further response was seen when the dose was increased to 19.5 mg/kg per day. This patient was treated with ganciclovir for a total of 192 days. No adverse reactions to ganciclovir were seen. On the last day of drug administration, there were persistent bilateral exudative retinal detachments and progressive optic nerve head involvement with optic disc pallor, despite quiescence of the retinitis.

Abstract
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.

Abstract
Two homosexual males with the "gay bowel syndrome' experienced an acute unilateral loss of vision. Both patients had white intraretinal lesions, which became confluent. One of the cases had a depressed cell-mediated immunity; both patients ultimately died after a prolonged illness. In one patient cytomegalovirus was cultured from a vitreous biopsy. Autopsy revealed disseminated cytomegalovirus in both patients. Widespread retinal necrosis was evident, with typical nuclear and cytoplasmic inclusions of cytomegalovirus. Electron microscopy showed herpes virus, while immunoperoxidase techniques showed cytomegalovirus. The altered cell-mediated response present in homosexual patients may be responsible for the clinical syndromes of Kaposi's sarcoma and opportunistic infection by Pneumocystis carinii, herpes simplex, or cytomegalovirus.

Abstract
The acute retinal necrosis syndrome is manifested by diffuse uveitis, vitritis, retinal vasculitis, and acute necrotizing retinitis (see Part 1). We studied the histopathology and electron microscopic findings of an eye enucleated from a 67-year-old man with typical acute retinal necrosis. Histology showed profound acute necrosis of the retina, retinal arteritis, and eosinophilic intranuclear inclusions in retinal cells. Electron microscopy demonstrated a herpes group virus in all layers of affected retina. The implications of these findings for antiviral and other treatments are discussed.

Abstract
A case is reported of histopathologically documented CMV retinitis. It is part of a recently appreciated syndrome in young homosexual men, in which cellular immune deficiency has been documented and in which CMV infection may play a role. This case demonstrates that CMV retinitis is not excluded by negative CMV serology or cultures.

Abstract
Six eyes in four patients with cytomegalovirus retinitis developed retinal holes and retinal detachment. Holes appeared in areas of necrosis and were typically large and round with shaggy edges. Differentiation from exudative detachment was sometimes difficult because of obscuration of the fundus by vitreous haze. Cryotherapy was successful in closing open breaks without detachment; cryotherapy and exoplant surgery were used effectively to treat the initial detachments. The occurrence of massive periretinal proliferation and late development of new areas of hole formation or retinitis complicated therapy for these detachments.

Abstract
We studied the relationship between the duration and intensity of cytomegalovirus viremia, cytomegalovirus complement fixing antibody, and cytomegalovirus retinitis in 61 renal transplant recipients. Five (8%) patients had chronic viremia which lasted more than six months. Two of the five developed typical cytomegalovirus retinitis and a severe fungal infection after intensive viremia of more than 11 months' duration. Retinitis did not develop in 22 patients with short-term viremia. Infectious cytomegalovirus was largely associated with polymorphonuclear leukocytes, but the virus was associated with monocytes during the immature granulocytic response accompanying one patient's terminal illness.

Abstract
The possibility that viruses can infect the peripheral autonomic nervous system (ANS) and cause a variety of acute, chronic or recurrent diseases, including such disorders as peptic ulcer, is proposed. By altering the functional activity of autonomic neurons or by seeding the target organs of these neurons with virus, infection of the ANS may produce a broad spectrum of clinical manifestations. Whether these manifestations are anatomically circumscribed or widespread will depend upon the route by which autonomic infection is acquired as well as the character of interaction between the virus and the infected autonomic neuron. In addition, it is proposed that autonomic ganglia may serve as reservoirs of latent viruses, insuring their preservation and intermittent transmission in the human community.

Abstract
Slow viruses produce diseases whose incubation periods range from several months to many years. Because of this long latency period, the lack of inflammation produced by these diseases and the lack of recoverable virus particles, it is only recently that the association has been made between the viruses and the diseases they cause. The detailed study of kuru, a neurologic affliction of a remote tribe of cannibals in New Guinea, was responsible for the synthesis of new and previously gathered information into a unified framework to explain not only kuru but other diseases as well. Since then, animal models, transmission experiments and histologic and biochemical studies have unveiled new links connecting viruses to previously obscure neurologic, neurophthalmic and ophthalmic entities.
