Abstract
Background: Human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS) causes impairment to the immune system, which then leads to immunocompromised conditions, and allows for opportunistic infection to invade many organs of the human body. Ocular involvement is very common; the various ocular complications may be asymptomatic and they may be the initial manifestations of the underlying diseases.Aim: This study aimed to determine the prevalence and the type of ocular manifestations that occur in HIV and AIDS patients.Setting: The study was conducted on ART (antiretroviral treatment) clinic patients in the Department of Ophthalmology at the Steve Biko Academic Hospital, Pretoria.Methods: This descriptive, cross-sectional study was conducted on HIV and AIDS patients referred from the ART clinic for complete ophthalmological evaluation, irrespective of the immune system status and presence or absence of symptoms. All the participants underwent an ophthalmologic evaluation, which included case history and ocular examinations of both anterior and posterior segments.Results: Out of the 177 participants, 72.3% had visual acuity of between 6/3 to 6/18, 10% had poor vision, 7% had lost one eye to ocular complications and 5% were blind. The most common anterior segment manifestations were uveitis and dry eye, whilst HIV-related retinopathy and papilledema were the most prevalent conditions in the posterior segment. Only three participants had third cranial nerve palsy.Conclusion: The prevalence of ocular manifestations was significantly higher with lower CD4+ cell counts, which could be regarded as predictors for the occurrence of ocular morbidity in HIV and AIDS patients.

Abstract
Corneal involvement in HIV-infected individuals may be broadly classified into two categories, namely, infectious and noninfectious with the vast majority of manifestations occurring in the former. In this article, we shall focus on these two categories and strive to highlight those presentations that should alert the clinician to suspect underlying HIV infection. Infectious group mainly consists of Herpitic group of viral infections. Bacterial causes may be due to Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeroginosa, alpha hemolytic Streptococcus, Micrococcus and Bacillus. Fungalf keratitis in HIV-infected individuals depends on the geographic locations from which patient comes. Microsporidia and Acanthamoeba are common Protozoal causes. Non-infective inflammatory causes include peripheral ulcerative keratitis, keratoconjunctivitis sicca, and squamous cell carcinoma of the conjunctiva. Severity which is abnormally severe or very minimally reactive makes the clinician suspect of immunosuppression.

Abstract
Purpose To report the changing patterns of ocular manifestations in human immunodeficiency virus (HIV) seropositive patients treated with highly active antiretroviral therapy (HAART). Methods The clinical charts of HIV seropositive patients, 735 examined from 1997 to 2003 and treated with HAART for at least 2 months (Group 1), and 838 untreated examined from 1988 to 1995 (Group 2), were reviewed to assess the frequency of ocular manifestations. Results HIV- related retinal microangiopathy and opportunistic retinal infections (cytomegalovirus retinitis and toxoplasmic retinochoroiditis) were significantly higher in Group 2 than 1 (p<0.0001), while in patients treated with HAART a statistically significant increase in the frequency of chalazion (p<0.0001), diabetic and hypertensive retinopathy (p<0.0001), lipid arc of the cornea (p<0.0001), cataract and glaucoma (p<0.0001), and uveitis (p=0.026) was observed. Conclusions HAART therapy has induced a dramatic decrease in the incidence of HIV-related microangiopathy and opportunistic retinal infection and the occurrence of new lesions related both to the metabolic alterations induced by HAART and to immune reconstitution, such as uveitis.

Abstract
BACKGROUND Introduction of highly active antiretroviral therapy has altered the course of disease for persons infected with human immunodeficiency virus by elevating CD4+ T-lymphocyte levels. Changes in the spectrum of systemic diseases encountered in human immunodeficiency virus-positive individuals are reported in the general medical literature. DESIGN Retrospective case series. PARTICIPANTS Sixty-one individuals infected with human immunodeficiency virus, who presented with uveitis when the peripheral CD4+ T-lymphocyte count was over 200 cells/μL. METHODS Standardized data collection at seven tertiary-referral inflammatory eye disease clinics. MAIN OUTCOME MEASURES Standardization of Uveitis Nomenclature anatomic classification and descriptors, cause of uveitis, and visual acuity RESULTS Peripheral CD4+ T cell counts varied between 207 and 1777 (median = 421) cells/μL at the time of diagnosis of uveitis. Uveitis was classified anatomically as anterior (47.5%), intermediate (6.6%), anterior/intermediate (16.4%), posterior (14.8%) and pan (14.8%). Specific causes of uveitis included infections (34.4%), with syphilis responsible for 16.4% of all cases, and defined immunological disorders (27.0%); no cause for the inflammation was identified in 34.4% of persons. Visual acuity was better than 6/15 in 66.7% and 6/60 or worse in 11.8% of 93 eyes at presentation, and better than 6/15 in 82.4% and 6/60 or worse in 8.8% of 34 eyes at 1 year of follow-up. CONCLUSIONS Both infectious and non-infectious forms of uveitis occur in individuals who are infected with human immunodeficiency virus and have preserved or restored peripheral CD4+ T cell levels. Individuals who are human immunodeficiency virus-positive and present with uveitis should be evaluated in the same way all patients with uveitis are assessed.

Abstract
Retinal endothelial cells line the arborizing microvasculature that supplies and drains the neural retina. The anatomical and physiological characteristics of these endothelial cells are consistent with nutritional requirements and protection of a tissue critical to vision. On the one hand, the endothelium must ensure the supply of oxygen and other nutrients to the metabolically active retina, and allow access to circulating cells that maintain the vasculature or survey the retina for the presence of potential pathogens. On the other hand, the endothelium contributes to the blood-retinal barrier that protects the retina by excluding circulating molecular toxins, microorganisms, and pro-inflammatory leukocytes. Features required to fulfill these functions may also predispose to disease processes, such as retinal vascular leakage and neovascularization, and trafficking of microbes and inflammatory cells. Thus, the retinal endothelial cell is a key participant in retinal ischemic vasculopathies that include diabetic retinopathy and retinopathy of prematurity, and retinal inflammation or infection, as occurs in posterior uveitis. Using gene expression and proteomic profiling, it has been possible to explore the molecular phenotype of the human retinal endothelial cell and contribute to understanding of the pathogenesis of these diseases. In addition to providing support for the involvement of well-characterized endothelial molecules, profiling has the power to identify new players in retinal pathologies. Findings may have implications for the design of new biological therapies. Additional progress in this field is anticipated as other technologies, including epigenetic profiling methods, whole transcriptome shotgun sequencing, and metabolomics, are used to study the human retinal endothelial cell.

Abstract
PURPOSE To describe changes in the acquired immunodeficiency syndrome (AIDS) epidemic that are important to ophthalmologists, to provide an overview of issues relevant to current evaluation and treatment of human immunodeficiency virus (HIV)-related eye disease, and to identify problems related to the eye and vision that require continued study. DESIGN Literature review and commentary. METHODS Selected articles from the medical literature and the author's clinical and research experiences over 25 years were reviewed critically. RESULTS The AIDS epidemic has had a profound impact on ophthalmology since the ophthalmic manifestations of AIDS were first described in 1982. The introduction of highly active antiretroviral therapy (HAART) has markedly reduced the incidence of cytomegalovirus (CMV) retinitis, but has not eliminated new cases altogether. Treatment strategies for CMV retinitis have evolved over the past decade. Current issues of importance include choice of initial anti-CMV drugs; time at which anti-CMV drug treatment is discontinued in patients who achieve immune recovery; strategies for monitoring patients at risk for disease reactivation; and management of complications (retinal detachment, immune recovery uveitis). Attention also is being directed to the problem of visual disturbances (reduced contrast sensitivity, altered color vision, visual field abnormalities) that can occur in HIV-infected individuals without infectious retinopathies. CONCLUSIONS Ocular disorders associated with HIV disease remain important problems in the United States, despite HAART, and increasingly are important worldwide. The approach to management of CMV retinitis has evolved from short-term treatment of a preterminal infection to the long-term management of what has become a chronic disease. Many challenges remain to be addressed.

Abstract
The objective of this article is to provide evidence-based recommendations for the management of patients with herpes zoster (HZ) that take into account clinical efficacy, adverse effects, impact on quality of life, and costs of treatment. Systematic literature reviews, published randomized clinical trials, existing guidelines, and the authors' clinical and research experience relevant to the management of patients with HZ were reviewed at a consensus meeting. The results of controlled trials and the clinical experience of the authors support the use of acyclovir, brivudin (where available), famciclovir, and valacyclovir as first-line antiviral therapy for the treatment of patients with HZ. Specific recommendations for the use of these medications are provided. In addition, suggestions are made for treatments that, when used in combination with antiviral therapy, may further reduce pain and other complications of HZ.

Abstract
PURPOSE To study the patterns of uveitis in various geographic regions. METHODS A systematic literature review was performed using the MEDLINE database, from 1966 to present. Studies that satisfied our described selection criteria were analyzed to provide a global perspective on uveitis. RESULTS Twenty-two studies, which were the best available representatives of Australia, North and South America, Europe, Asia, and Africa, were included in the final analysis. The distribution of uveitis cases according to the anatomical site of inflammation in the various regions, and the causes and clinical disease associations of anterior, intermediate, posterior, and pan-uveitis were studied for each of the regions and a comparative analysis was performed. CONCLUSIONS There are similarities and distinct differences in the patterns of uveitis in the various geographic regions. Such patterns of uveitis are influenced by combinations of geographical, environmental, and genetic factors.

Abstract
Injection drug use can result in a variety of severe ocular conditions. Hematogenous dissemination of various fungi and bacteria may produce endophthalmitis with resultant severe visual loss. Retinal arterial occlusive disease may result from talc and other particulate emboli. Most commonly, life-threatening systemic diseases such as endocarditis and HIV infection secondarily affect the eye. Because many of these conditions may result in blindness if untreated, accurate diagnosis and prompt initiation of therapy are essential.

Abstract
The objective of this prospective study was to evaluate the efficacy and complications of the use of an intraocular sustained-release ganciclovir implant for the treatment of active cytomegalovirus (CMV) retinitis in AIDS patients. Thirty-nine eyes of 26 patients were submitted to ocular surgery. All patients underwent complete ocular examination before and after surgery. The surgical procedure was always done under local anesthesia using the same technique. The mean time for the surgical procedure was 20 min (range, 15 to 30 min). The average follow-up period was 3.7 months. Of all patient, only 4 presented recurrence of retinitis after 8, 8, 9 and 2 months, respectively. Three of them received a successful second implant. All 39 eyes of the 26 patients presented healing of retinitis as shown by clinical improvement evaluated by indirect binocular ophthalmoscopy and retinography. Retinitis healed within a period of 4 to 6 weeks in all patients, with clinical regression signs from the third week on. Six (15.4%) eyes developed retinal detachment. None of the patients developed CMV retinitis in the contralateral eye. The intraocular implant proved to be effective in controlling the progression of retinitis for a period of up to 8 months even in patients for whom systemic therapy with either ganciclovir or foscarnet or both had failed. The intraocular sustained-release ganciclovir implant proved to be a safe new procedure for the treatment of CMV retinitis, avoiding the systemic side effects caused by the intravenous medications and improving the quality of life of the patients.

Abstract
OBJECTIVE The authors prospectively studied visual outcome, relapse, complications, and survival of patients with acquired immune deficiency syndrome (AIDS)-related cytomegalovirus (CMV) treated with high-dose intravitreous ganciclovir (2 mg/0.1 ml) injections. The outcomes were compared with those of patients treated with standard doses of intravenous ganciclovir in the same institution. The histopathologic and electrophysiologic effects of high-dose intravitreous ganciclovir injections in rabbits also were studied. DESIGN A nonrandomized case series. PARTICIPANTS A total of 42 patients (74 eyes) were treated with intravitreous injections and 18 patients (27 eyes) were treated with intravenous ganciclovir. Five eyes of three New Zealand white rabbits were injected with ganciclovir, and the sixth eye was a control specimen. INTERVENTION Patients treated with intravitreous injections received twice-weekly doses of 2 mg/0.1 ml ganciclovir for 3 weeks, then weekly injections. Patients treated with intravenous ganciclovir received standard doses. Patients were monitored with regular examinations. Rabbit eyes were given intravitreous injections of 1 mg/0.1 ml of ganciclovir weekly for 4 weeks. MAIN OUTCOME MEASURES Assessments of vision, retinal inflammation, and survival were made. Electroretinograms were performed on the rabbit eyes, and they were processed for light and electron microscopy. RESULTS In the intravitreous group, visual acuity (VA) was stable in 64 of 74 eyes, 5 improved, and 5 deteriorated. Sixty-three (85%) of 74 eyes had final VA of 20/20 to 20/40. Relapse occurred in five eyes (7%; median time, 42 weeks). There were three cases of endophthalmitis. Median survival after diagnosis of CMV retinitis was 36 weeks. In the intravenous group, VA was stable in 18 eyes, 0 improved, and 9 deteriorated. Sixteen (59%) of 27 eyes had final VA of 20/20 to 20/40. Relapse occurred in 15 eyes (56%) at a median time of 21 weeks. Median survival was 21 weeks. The rabbit studies showed no evidence of toxicity. CONCLUSION High-dose intravitreous ganciclovir effectively suppressed CMV retinitis, preserved vision, and prevented relapse without deterioration in survival.

Abstract
OBJECTIVE Cytomegalovirus (CMV) retinitis is a relatively common opportunistic infection in late-stage HIV disease, causing significant morbidity and mortality. Prophylactic use of oral ganciclovir has recently been shown to decrease the incidence of CMV retinitis but is relatively expensive and may not be very well tolerated by many patients. We performed a decision analysis to assess the cost-effectiveness of prophylactic oral ganciclovir therapy. METHODS A decision analysis using a Markov approach compared absence of prophylaxis and prophylaxis with oral ganciclovir. Estimates of effectiveness of prophylaxis and costs of illness were obtained from published literature. Drug costs were based on national average wholesale prices. All health care costs were based on 1996 U.S. dollars. Sensitivity analyses were done over ranges of estimates of cost and effectiveness. RESULTS Using our baseline estimates of cost and effectiveness, use of oral ganciclovir prophylaxis in patients with CD4 counts <50 cells/mm3 would be associated with average lifetime health care costs of $104,746, compared with $90,985 for no prophylaxis. Using oral ganciclovir, the average quality-adjusted life-years (QALYs) would be 2.05, and the CMV retinitis-free life-years would be 1.64, compared with 1.87 and 1.27, respectively, for no prophylaxis. The incremental cost-utility of oral ganciclovir is $76,676 per year of life saved and $37,542 per year of additional CMV retinitis-free life. Oral ganciclovir would become more cost-effective relative to no prophylaxis if the probability of CMV retinitis while taking oral ganciclovir declined. Oral ganciclovir would be less cost-effective if the cost of treating CMV retinitis declines, if our estimates of quality of life are low, or if the overall incidence of CMV retinitis declines. CONCLUSIONS Oral ganciclovir is a less cost-effective approach than several other interventions used for HIV-disease prophylaxis. It would potentially become cost-effective if it is possible to target oral ganciclovir prophylaxis to patients who are most likely to benefit.

Abstract
BACKGROUND Eye disease in children infected with HIV is uncommon, but there is little information on which children require screening or surveillance and the management of those with retinitis. METHODS We examined 12 children with symptomatic HIV disease (of a cohort of 98 HIV-positive children) using indirect ophthalmoscopy. When retinitis was found it was documented photographically at the time of diagnosis and on follow-up. RESULTS Four cases of infective retinitis were diagnosed: three with probable cytomegalovirus retinitis and one with progressive outer retinal necrosis. CONCLUSION Detection of reactivation is difficult and we recommend fundus photography under general anaesthesia wherever possible. Children with other end-organ disease, symptomatic eye disease and advanced HIV disease with severe immunosuppression require ophthalmological surveillance.

Abstract
PURPOSE We describe the clinical course of 12 eyes of 10 patients in whom recurrent cytomegalovirus (CMV) retinitis exhibited a foveal-sparing pattern. METHODS We retrospectively reviewed the case records and photographic charts of 10 patients (12 eyes) with the acquired immunodeficiency syndrome (AIDS), in whom recurrent CMV retinitis exhibited a foveal-sparing pattern within 1500 mm of the foveola. RESULTS The site of primary retinitis was temporal in 10 eyes of nine patients in whom it was known. The median number of recurrences up to the observation of foveal-sparing retinitis was two (range one to eight), and five patients had active CMV retinitis despite treatment for at least two continuous months. Once established, the median rate of progression in a non-foveal vector was 2.3 times faster than toward the fovea, and the median time to reduction in acuity to < 6/30 (or death) was 11 to 14 weeks. Three eyes of three patients retained 6/30 or better acuity up to death. Foveal CMV retinitis ultimately reduced acuity to < 6/30 in five eyes. Six eyes suffered retinal detachment, involving the fovea in five, and being the primary reason for acuity of < 6/30 in four. Four patients suffered dose-limiting toxicity. CONCLUSION Foveal-sparing CMV retinitis arises in patients with recurrent CMV retinitis resistant to treatment ('clinically resistant'), particularly that which has arisen temporally. Despite its foveolar proximity, and ultimate significant loss of function, the pattern of progression allows for preservation of useful foveal vision for longer periods than would have been expected.

Abstract
BACKGROUND The AIDS database at Fairfield Hospital, Melbourne, maintains information on eye pathology as identified by the three visiting ophthalmologists. Patients underwent an eye consultation: if they had ocular symptoms; if signs were seen on direct ophthalmoscopy by physicians; or when their CD4+ve cell count fell below 50/microL. The first AIDS-associated eye signs were identified in mid-1984. In the subsequent decade, 3257 patients in Victoria tested positive for HIV, and 845 of the 1123 who developed AIDS were treated at Fairfield Hospital. METHODS We undertook a retrospective review of the Fairfield Hospital database to identify the AIDS-associated ocular problems seen. RESULTS Some 723 patients had an eye consultation. In the earliest stage of HIV infection, minor non-specific ophthalmic involvement may occur. As the disease progresses, microvasculopathy (cottonwool spots and haemorrhages) appears. External disease also occurs such as molluscum contagiosum and Kaposi's sarcoma of the conjunctiva. With more suppression of the immune system, opportunistic infections become common, and have a considerable visual morbidity. Cerebral toxoplasmosis (117 patients) is only rarely associated with ocular involvement (three patients), but cytomegalovirus (CMV) commonly causes retinitis [204 patients (24%)]. It has been the AIDS-defining illness in 26 patients. A majority had the disease confined to one eye. Mean CD4 cell count at onset is 15 +/- 5 microL and it has been associated with a viraemia in all but two patients. Late complications of CMV retinitis include relapse in 41 (20%), spread to the other eye in 24 (12%), and retinal detachment in 30 (15%). Visual impairment follows from retinal destruction, optic nerve involvement, and retinal detachment. CONCLUSION The ophthalmic workload from late ocular complications of AIDS is increasing. Newer and more effective methods of treatment are being developed. Ophthalmologists are becoming more aware of the need for universal precautions to avoid risks from this and other blood-borne infections.

Abstract
About 20%-30% of patients with AIDS will develop cytomegalovirus (CMV) retinitis when they are severely immunodeficient (CD4 cell count below 40 cells/microL). It causes extensive retinal damage with visual deficits, and relapses are frequent. Intravenous ganciclovir and foscarnet are standard therapy, but their high toxicity and long term intravenous access mean that advances in treatment, including oral prophylactic agents, intravitreal injections and surgical implants, may provide a better quality of life for patients. Prophylactic ophthalmological screening of patients with CD4 cell counts below 100 cells/microL to detect asymptomatic retinitis is needed.

Abstract
PURPOSE To investigate an association of the severity of the human immunodeficiency virus (HIV) disease with decreased tear production in a controlled setting. PATIENTS AND METHODS Seventy-two patients (144 eyes) and 30 age- and sex-matched control subjects (60 eyes) were studied prospectively. Tear production was measured using the Schirmer I test (measured in millimeters after 5 minutes). Patients were classified into three clinical groups: asymptomatic HIV infection, lymphadenopathy syndrome (LAS) or acquired immune deficiency syndrome (AIDS)-related complex (ARC), and AIDS. Additionally, patients were classified according to the CD4+ lymphocyte count. RESULTS Tear production (mean +/- standard deviation) did not differ (P = 0.32) among eyes of patients with asymptomatic HIV infection (17.1 +/- 10.8; n = 14), LAS or ARC (18.3 +/- 10.3; n = 70), and AIDS (20.7 +/- 10.3; n = 60). In addition, mean tear production was not decreased significantly when comparing each clinical group with the control subjects (17.8 +/- 4.4). However, the relative frequency of eyes with significantly decreased tear production (< 9 mm) was 23.6% in all 144 eyes. In addition, the relative frequency of significantly decreased tear production did not differ (P = 0.52) between eyes of patients with asymptomatic HIV infection (35.7%), LAS or ARC (21.4%), and AIDS (24.1%). In addition, the relative frequency of significantly decreased tear production did not differ (P = 0.30) between eyes of patients with a CD4+ count of more than 400 cells/microliters (23.1%; n = 26), 400 to 200 cells/microliters (31.3%; n = 48), 200 to 50 cells/microliters (14.3%; n = 42), and less than 50 cells/microliters (21.4%; n = 28). CONCLUSION The authors data show that decreased tear production occurs in approximately 20% to 25% of patients with HIV infection. This increased frequency of decreased tear production is not associated with the CD4+ count, or related to the severity of HIV disease, respectively. The possibility of an autoimmune-like pathogenesis of abnormalities of tear production in patients with HIV infection should be studied intensively.

Abstract
PURPOSE We sought to understand better the efficacy and risks of local therapies (direct placement of drug into the eye) for the treatment of cytomegalovirus retinopathy. This understanding can be used to design rational treatment regimens, to formulate indications for use of local therapy, and to establish criteria for assessment of future results in this area. METHODS We collected information about local therapies through a review of published literature. RESULTS Intraocular injection of ganciclovir and foscarnet and implantation of intraocular devices that slowly release ganciclovir are able to decrease the activity of cytomegalovirus retinopathy lesions and prevent their enlargement for variable periods of time. The time to disease progression (lesion enlargement) may be longer with intraocular devices than with current treatments using intravenously administered antiviral drugs. Local therapies have many advantages (for example, convenience, reduced cost, and lack of systemic toxicity), but there are potential disadvantages, including endophthalmitis, increased rates of retinal detachment, and development of nonocular cytomegalovirus disease and cytomegalovirus retinopathy in fellow, uninvolved eyes. CONCLUSIONS Local therapies are effective for the treatment of cytomegalovirus retinopathy, but their relative risks and benefits, when compared with those of intravenous drug therapy, have yet to be fully evaluated. We anticipate that local therapy will be an important treatment modality for selected patients with cytomegalovirus retinopathy. Indications include the use of local therapy as an alternative therapy for patients who are unable to receive systemic therapy (intolerance to intravenous or oral medication, or lack of intravenous access) and as supplementation in patients whose retinal disease is incompletely controlled by maximum tolerated systemic medications. The use of local therapy as sole initial treatment in lieu of systemic therapy remains controversial. Its most useful role may be in conjunction with oral forms of antiviral drugs now in development.

Abstract
Although various methods of immunosuppression have been used to enhance susceptibility of mice to murine cytomegalovirus (MCMV) retinitis, none reproduce the unique complexity of immune deficiency experienced by patients during the progression of AIDS. C57BL/6 mice are susceptible to a retrovirus-induced murine acquired immune deficiency syndrome (MAIDS), characterized by progressive immune dysfunction which shares many features with AIDS. We therefore evaluated the frequency and severity of MCMV retinitis in C57BL/6 mice with MAIDS. Following subretinal inoculation of MCMV, nearly 90% of mice with MAIDS developed a necrotizing retinitis 8 to 10 days postinfection, whereas retinitis was observed in only 8% of age-matched immunocompetent control mice. Histopathologic analysis of the retinitis that developed in mice with MAIDS revealed features similar to those found in AIDS-related CMV retinitis. Eyes from MAIDS animals also contained on average higher amounts of infectious virus when compared with eyes from control animals. We conclude that retrovirus-induced immunosuppression increases susceptibility of C57BL/6 mice to MCMV retinitis.

Abstract
A new case of AIDS-associated, small noncleaved cell (Burkitt's) lymphoma that presented as an orbital mass is described. Extraocular muscle involvement was documented by computed tomography and confirmed by orbital biopsy. Extensive abdominal involvement was subsequently diagnosed and this caused the patient's death only 15 days after the initial consultation and orbital biopsy. A literature review discloses only eight previous case reports of AIDS-associated non-Hodgkin's lymphoma (NHL) involving the orbit: two cases of Burkitt's type and six cases of large cell immunoblastic type. Three additional cases of orbital NHL can be found among larger series of AIDS cases. Affected patients are uniformly young adult males with a history of homosexuality and/or IV drug abuse. Variations in clinical presentation are discussed. Although the morphology of the histopathologic specimen in our case was consistent with a high-grade, small noncleaved cell NHL, flow cytometry revealed an atypical immunophenotype for Burkitt's lymphoma in that CD20 and immunoglobulin light chain antigens were not expressed. Morphologic classification and immunophenotypic characteristics of AIDS-associated NHLs are discussed.

Abstract
We conducted a review to investigate the prevalence of human immunodeficiency virus (HIV), or acquired immunodeficiency syndrome (AIDS), in patients with herpes zoster ophthalmicus, as well as the incidence of acute retinal necrosis after herpes zoster ophthalmicus. All charts of patients seen at our institution between 1987 and 1992 with a primary diagnosis of herpes zoster ophthalmicus were reviewed. Of 112 patients with herpes zoster ophthalmicus, 29 (26%) had HIV or AIDS. All these patients were younger than 50 years at the time of diagnosis. Five of 29 (17%) immunocompromised patients had acute retinal necrosis after herpes zoster ophthalmicus. No acute retinal necrosis was identified in the nonimmunocompromised patients after herpes zoster ophthalmicus. We recommend that all patients younger than 50 years who have herpes zoster ophthalmicus at initial examination be tested for HIV. Additionally, HIV-infected patients should be monitored closely after herpes zoster ophthalmicus for development of acute retinal necrosis. Long-term oral prophylactic as well as initial high-dose intravenous acyclovir may be appropriate in HIV-infected individuals with herpes zoster.

Abstract
PURPOSE The purposes of this study are to determine the incidence of infectious opportunistic choroiditis in patients with the acquired immune deficiency syndrome (AIDS), to study the association of these choroidal infections with systemic dissemination, and to investigate the life expectancy and cause of death in patients with infectious opportunistic choroiditis. METHODS A total of 470 eyes of 235 consecutive autopsies of patients with AIDS were examined by histopathologic methods. The clinical charts and autopsy reports of these patients were subsequently reviewed for presence of systemic dissemination of various infectious agents. RESULTS Of the 235 patients, 18 were found to have infectious choroiditis. The etiologic agents found were: Cryptococcus neoformans, Pneumocystis carinii, Mycobacterium tuberculosis, Histoplasma capsulatum, Candida, Aspergillus fumigatus, Toxoplasma gondii, and Mycobacterium avium-intracellulare. In 15 of these 18 patients, the cause of death was considered to be due to systemic dissemination of the organism causing the choroiditis. Only 4 of the 18 cases of infectious choroiditis were diagnosed during life, and the survival time of these patients after diagnosis was only 25 days. Five of the 18 patients also were found to have cytomegalovirus (CMV) infection of the retina. CONCLUSION Multifocal choroiditis due to endogenous infectious emboli in patients with AIDS reflects systemic dissemination and localization of infectious agents predominantly in the choriocapillaris. Early diagnosis and treatment are imperative and may be life-saving.

Abstract
The most common ocular complication in patients with the acquired immunodeficiency syndrome (AIDS) is cytomegalovirus retinitis. Incidence figures vary from 20 to 76%. Patients with cytomegalovirus may suffer from mild visual impairment of one or both eyes, but as the disease progresses the retinitis will almost certainly lead to blindness. Although cytomegalovirus retinitis is not a life-threatening infection, it can largely diminish the patient's quality of life. Clinical trials for the treatment of cytomegalovirus retinitis with a number of antiviral drugs have resulted in two drugs of choice, ganciclovir and foscarnet. Both drugs have an initial efficacy with induction therapy of 80-90%, but maintenance therapy is always needed to prevent a relapse. To exclude systemic side-effects of ganciclovir, intravitreal administration has been investigated with good results. Combination therapy of foscarnet and ganciclovir may be worthwhile in resistant cytomegalovirus retinitis.

Abstract
We studied the occurrence of ulcerative keratitis in five eyes of four patients who were examined at the University of Maryland Hospital ophthalmology clinic over a 12-month period. All were young women who were intravenous drug abusers, with no known predisposing factors for ulcerative keratitis. Two patients had acquired immunodeficiency syndrome (AIDS), one was human immunodeficiency virus (HIV)-positive, and the fourth refused HIV testing. One had a corneoscleral limbus to corneoscleral limbus keratitis; three had inferiorly located corneal ulcers (bilateral in one patient with AIDS). Corneal cultures disclosed Capnocytophaga species in the corneoscleral limbus to corneoscleral limbus keratitis. The remaining ulcers were polymicrobial; cultures of three grew Candida albicans, cultures of two grew alpha-hemolytic streptococci, cultures of two grew Staphylococcus aureus, and culture of one grew Pseudomonas aeruginosa. Treatment with topical fortified antibiotics and antifungal agents resulted in complete healing in all four inferiorly located ulcers. The corneal ulcer became perforated and the eye was eviscerated. Histopathologic analysis of the eviscerated specimen disclosed acute keratitis with necrosis and no microorganisms.
