Abstract
Purpose: To characterize the presenting features of cytomegalovirus (CMV) retinitis in HIV-positive patients in a developing country in the HAART era.Methods: Retrospective chart review of all patients with CMV retinitis seen at a tertiary-care referral center between January 2006 to June 2017. Demographic and clinical data were collected to study the presenting features and risk factors for blindness.Results: Fifty-five patients with treatment-naïve CMV retinitis were enrolled; 75% were males. CD4 counts were below 50 cells/µL in 51.1%. Bilateral presentation was seen in 61.5%. Half (50.6%) of the eyes were blind at first examination. Zone 1 involvement was present in 46% of the eyes. Retinal area involvement > 25% was the only factor associated significantly with higher incidence of blindness (p = 0.016).Conclusions: There was extensive and bilateral presentation of CMV retinitis due to delayed presentation. Screening for CMV retinitis, irrespective of CD4 counts, may help in developing nations.

Abstract
PURPOSE To study the characteristics and visual outcome of cytomegalovirus retinitis in patients of a tertiary referral ophthalmology center. METHODS This retrospective cross-sectional study included 16 patients who presented with CMV retinitis between February 2014 and January 2017. Demographics, clinical signs, course of treatment, and visual and anatomical results were analyzed. RESULTS Twenty five eyes of 16 patients were included. Eleven (68.8%) were females. The mean age was 29.37 ± 17.12 (range 11-73) years. Involvement was bilateral in 9 (56.2%) cases. HIV serology was negative in all patients. Best-corrected visual acuity was 0.57 ± 0.55 logarithm of the minimal angle of resolution (LogMAR) at the time of presentation and decreased to 0.69 ± 0.55 LogMAR on final visit (P = 0.332). None of the patients participating in this study was HIV-positive. CONCLUSION CMV retinitis is a devastating complication in immunosuppressed. The visual acuity usually decreases despite aggressive appropriate treatment. This observation supports the increasing incidence of CMV infection in non-HIV patients.

Abstract
Cytomegalovirus (CMV) retinitis is a late complication of organ and hematopoietic stem cell transplant, the risk of which depends on the degree of immunosuppression. With the institution of preemptive ganciclovir therapy early after transplant, most patients survive episodes of life-threatening CMV infection during the early months (usually the first 3 months) after transplant and hence late onset of CMV disease, such as CMV retinitis, is being recognized more frequently. Direct involvement of the macula or optic head remains the leading cause of visual loss in patients with CMV retinitis, but there are few studies investigating the management of this condition. Herein, we present the case of 28-year-old man who had acute myeloid leukemia and developed CMV retinitis with bilateral cystoid macular edema and optic swelling in the right eye 6 months after bone marrow transplant. He received treatment with intravitreal methotrexate in the right eye in combination with oral valganciclovir. Visual acuity improved 1 month after four weekly injections of intravitreal methotrexate 400 µg/0.1 mL. Resolved disc swelling and regression of macular edema were also observed. By comparing binocular outcome, we present our findings and discuss the possible efficacy and safety of this treatment with respect to regression of anatomical damage and improvement in visual acuity.

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
BACKGROUND The administration of systemic immunosuppressive agents to recipients of solid organ or bone marrow transplants results in an immunocompromised status. As the number of organ recipients and their life span increase with recent progress in organ transplantation, ocular complications tend to become more diverse and serious. METHODS From 1995 to 2005, 3656 cases of organ transplantations were performed at Asan Medical Center. The medical records of 1198 of these patients who had been examined at the Department of Ophthalmology were reviewed. RESULTS Retinal complications were diagnosed in 33 of the transplant recipients; five with bone marrow transplantation, 16 with kidney transplantation, seven with liver transplantation (LT), and five with heart transplantation. Diagnoses included 11 cases of CMV (cytomegalovirus) retinitis, three of acute retinal necrosis, one of progressive outer retinal necrosis, five of fungal chorioretinitis, one of toxoplasmic retinochoroiditis, three of central retinal vein occlusion, and nine of central serous chorioretinopathy. While CMV, fungal, or toxoplasmic chorioretinitis developed frequently in association with extraocular infection or organ rejection, herpetic infection manifested only in the eye without any rejection. Most infectious cases responded well to the standard therapeutic regimen. Interestingly, central retinal vein occlusion developed exclusively following LT, possibly in relation to coagulation cascade abnormality. CONCLUSIONS To our best knowledge, this comprehensive review presents the largest series of ocular complication in organ transplant recipients. Familiarity with the potential ocular complications as well as a high index of suspicion is warranted to the practicing ophthalmologists.

Abstract
PURPOSE To describe the characteristics and outcomes of patients with cytomegalovirus (CMV) retinitis in the absence of human immunodeficiency virus (HIV) infection. DESIGN Retrospective cohort study. METHODS Consecutive patients with CMV retinitis in the absence of HIV infection were identified at a university hospital. Demographic and clinical characteristics were noted at the time of CMV retinitis. Outcomes were determined retrospectively. Main outcome measures were rates of second eye involvement, vision loss, rhegmatogenous retinal detachment (RD), immune recovery uveitis, progression of retinitis, and mortality. RESULTS The clinical characteristics of CMV retinitis in 18 patients (30 eyes) without HIV infection diagnosed between January 1, 1984, and April 13, 2003, were similar to those of patients with HIV infection. The incidences of visual loss to the levels of 20/50 or worse and of 20/200 or worse were 17% per eye-year and 14% per eye-year, respectively. The observed incidence of RD was 3.7% per eye-year, and the mortality rate was 23% per person-year. Following reduction of immunosuppression, 10 patients (56%) who discontinued anti-CMV therapy remained free of retinitis progression. The incidence of immune recovery uveitis was 13% per person-year. CONCLUSIONS In our series, CMV retinitis in patients without HIV infection had a clinical course similar to that in patients with AIDS treated with highly active antiretroviral therapy (HAART), except the incidence of RD was lower for patients without AIDS. A substantial number of patients no longer required long-term anti-CMV therapy after adjustment of immunomodulatory therapy.

Abstract
Rheumatic diseases are not commonly associated with cytomegalovirus (CMV) retinitis. We report a case of bilateral CMV retinitis in a human immunodeficiency virus-seronegative patient with systemic lupus erythematosus (SLE) who was undergoing hemodialysis for end-stage renal disease. The CMV retinitis in this patient was associated with combined azathioprine and low-dose corticosteroid therapy for lupus flare. This association may have important clinical implications because this drug combination is used routinely to treat active SLE. Our patient responded to discontinuation of azathioprine, reduction of the corticosteroid dose, and systemic administration of ganciclovir. We recommend that clinicians maintain heightened awareness of the possibility of CMV retinitis in patients with SLE and end-stage renal disease who are receiving azathioprine and low-dose corticosteroids.

Abstract
PURPOSE To review the clinical features, natural history, potential pathogenic mechanisms, differential diagnosis, and management of optic neuritis in multiple sclerosis. METHODS Relevant literature regarding optic neuritis in multiple sclerosis from 1970 to the present was reviewed. RESULTS Optic neuritis is an acute inflammatory optic neuropathy. It is the most common type of optic neuropathy causing acute visual loss in young adults (peak age at 30-40 years), especially among women. Patients usually present with an acute reduction of visual acuity, orbital pain exacerbated by eye movements, dyschromatopsia, and an afferent papillary defect, with or without swelling of the optic nerve head. Visual field testing most often reveals central defects, but others, such as centrocecal, can also occur. Magnetic resonance image (MRI) scanning of the brain should be undertaken in all cases of acute optic neuritis for diagnostic and prognostic purposes. The brain lesions of multiple sclerosis are commonly seen as T2 ovoid high-signal white matter lesions on MRI scans of the brain located in perivenular regions perpendicular to ventricles with variable enhancement. For atypical presentations of optic neuritis, additional laboratory tests, such as cerebrospinal fluid analysis, serologic tests, and visual evoked potentials, prove to be useful in the diagnosis and subsequent management of the patient. The recommended treatment for optic neuritis is intravenous steroids, as shown in the Optic Neuritis Treatment Trial (ONTT). CONCLUSION Optic neuritis is often the initial presentation of multiple sclerosis. Recent advances in the understanding of the immune basis for multiple sclerosis has led to earlier and more effective treatment of this disease.

Abstract
PURPOSE Eighty-six post-mortems of AIDS patients were reviewed microscopically and the presence of cytomegalovirus (CMV) infection in the viscera, brain and eye was recorded. METHODS Immunohistochemical stains and in situ hybridisation with a CMV probe were performed. RESULTS AND CONCLUSION CMV infection was observed in 63% of the cases. Visceral, cerebral and ocular involvement were overall 49%, 33% and 29%, respectively. The visceral form with no concomitant ocular and/or cerebral infection was the main cause of death (31%) in the 54 CMV-infected patients. Although CMV retinitis occurred mostly (20%) as a component of systemic disease, in 13% of the CMV-infected patients the eyes only were involved, while there were no cases with CMV limited to the brain. In the absence of systemic involvement, 9% of the cases showed concomitant ocular and cerebral infection, but because we failed to observe CMV optic neuritis without ocular involvement, retrograde viral spread from the brain through the optic nerve appears to be an infrequent mechanism of CMV retinitis.

Abstract
PURPOSE To report the observation that a transient vitreous inflammatory reaction may develop in the eyes of patients with acquired immunodeficiency syndrome (AIDS), cytomegalovirus retinitis, and an increased CD4+ T-lymphocyte count during treatment with antiretroviral therapy including a protease inhibitor. METHODS We reviewed the medical records of eight patients with AIDS and cytomegalovirus retinitis who developed vitreous inflammatory reactions greater than those usually seen with this disease. RESULTS Vitreous inflammatory reactions obscured the view of the posterior pole in all patients. No iris nodules, synechiae, glaucoma, or cystoid macular edema were observed. Six patients had unilateral cytomegalovirus retinitis, and, in each, the inflammation occurred only in the eye with cytomegalovirus retinitis. The vitreous inflammatory reactions were associated with clinically inactive cytomegalovirus retinitis in six patients, with disease reactivation in one patient, and were present at diagnosis of active disease in one patient. Cytomegalovirus retinitis has not recurred in any of these patients since their episodes of vitreous inflammation. Vitreous inflammation developed in all eight patients after a substantial increase in CD4+ T-lymphocyte counts caused by combination antiretroviral therapy. Five patients had CD4+ T-lymphocyte counts of greater than 100 cells per microl at the time the vitreous inflammatory reaction developed. No other causes of uveitis were found. CONCLUSIONS Patients with AIDS and cytomegalovirus retinitis may develop transient intraocular inflammation associated with combination antiretroviral therapy. We believe that this inflammation reflects an improved immune response against cytomegalovirus.

Abstract
AIM To determine the value of the polymerase chain reaction (PCR) technique and the analysis of intraocularly produced antibodies by calculating a Goldmann-Witmer quotient (GWq) as diagnostic assays in the confirmation of a clinically diagnosed cytomegalovirus (CMV) retinitis in a group of unselected AIDS patients. METHODS Eleven samples of undiluted ocular fluid, obtained from nine AIDS patients with a clinically diagnosed CMV retinitis were analysed for the presence of genomic DNA from CMV, HSV-1, VZV, and EBV by PCR. Nine of these samples were analysed for the presence of locally produced IgG antibodies against these herpesviruses by calculating a GWq. Ten samples obtained from patients with various entities of clinical non-herpetic uveitis and 17 samples of aqueous humour obtained at cataract surgery were used as controls. RESULTS In 10 out of 11 samples from AIDS patients (91%) the presence of CMV DNA was demonstrated. In four out of nine (44%) patients this was accompanied by CMV DNA in the blood indicating a CMV viraemia. In one sample, VZV DNA was detected and in another sample both CMV and VZV DNA were detected. No HSV-1 or EBV DNA could be demonstrated in these 11 samples. In contrast, simultaneous analysis of locally produced IgG antibodies against herpesviruses could not confirm the initial diagnosis of CMV retinitis. Ocular fluid samples obtained from 10 control uveitis patients were negative for DNA from CMV, VZV, and EBV by PCR. In one of 10 uveitis control samples HSV-1 DNA was detected; antibody analysis did not confirm this. In the uveitis control group, a significant GWq was calculated in one sample for HSV-1 and in another sample for VZV. The cataract control samples were all herpesvirus DNA negative by PCR. CONCLUSIONS To establish the diagnosis of CMV retinitis in AIDS patients, ophthalmoscopic examination is a sensitive method. In confirming a diagnosis in indistinctive cases, application of a PCR assay detecting CMV DNA is a more sensitive method than analysis of locally produced antibodies by calculating a GWq. In clinical non-herpetic uveitis, secondary release of HSV-1 and VZV should be considered requiring additional therapeutic anticipation.

Abstract
We prospectively studied 132 patients with acquired immunodeficiency syndrome (AIDS) to determine the cross-sectional prevalence of cytomegalovirus retinitis. All patients had serum CD4+ lymphocyte counts to determine the degree of immune dysfunction. Correlations between CD4+ counts, the presence of cytomegalovirus retinitis or human immunodeficiency virus (HIV)-related noninfectious retinal vasculopathy, and ocular symptoms were made. The study disclosed that 26 of 132 patients with AIDS (20%) had cytomegalovirus retinitis. However, subset analysis according to CD4+ count disclosed that in patients with CD4+ counts of 50 cells/mm3 or less, 26 of 87 (30%) had cytomegalovirus retinitis, whereas in patients with CD4+ counts of 50 cells/mm3 or more, none of 45 was noted to have cytomegalovirus retinitis. Similarly, 46 of 132 patients (35%) were noted to have HIV-related noninfectious retinal vasculopathy, with a trend toward increasing prevalence associated with declining CD4+ count. In patients with CD4+ counts of 50 cells/mm3 or less, 39 of 87 (45%) had HIV-related noninfectious retinal vasculopathy, whereas seven of 45 patients (16%) with CD4+ counts of 50 cells/mm3 or more were noted to have these changes. We confirmed the clinical impression that cytomegalovirus retinitis and HIV-related noninfectious retinal vasculopathy are late manifestations of AIDS, demonstrated an increased risk for patients with low CD4+ counts, and suggested a basis for coherent chemoprophylaxis and screening strategies for cytomegalovirus retinitis.

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.

Cytomegalovirus (CMV) retinitis is a common and one of the most serious ophthalmic manifestations of the acquired immunodeficiency syndrome (AIDS). Early recognition is essential in the proper management of this necrotizing and progressive infection. We discuss an unusual presentation of CMV retinitis which appeared initially only in the foveal region.

Abstract
Cytomegalovirus retinitis is a frequent and serious complication of various conditions, including diseases characterized by impaired immunity, such as the acquired immunodeficiency syndrome. Due to recent advances in the treatment of cytomegalovirus retinitis, accurate diagnosis and management have become increasingly important. In this review, the authors present the epidemiology, clinical features, diagnostic testing, treatment with complications, and prognosis of cytomegalovirus retinitis. A differential diagnosis is presented and the characteristic ocular lesions are illustrated.

Abstract
Cytomegalovirus infections are still the most important infectious complications after organ transplantation. Besides historical notes this review will deal with new aspects concerning the epidemiology of the CMV, diagnostic modalities of CMV infection, the delicate counterbalance between the immune system and the CMV, as well as the symptomatology of this infection. Furthermore, aspects like prophylaxis and new, promising therapeutic regimes for treatment of infection will be dealt with. Although this update is applicable for all types of solid organ transplantation, emphasis will be on renal transplantation.

Abstract
Retinal pigment epithelium (RPE) was isolated from the globe of a donor positive for human immunodeficiency virus (HIV) who had cytomegalovirus (CMV) retinitis secondary to acquired immunodeficiency syndrome (AIDS). In culture, the cells exhibited normal epithelioid morphology by phase contrast microscopy. After two weeks the cells developed cytomegaly and dense intranuclear and cytoplasmic inclusions and, eventually, died. Transmission electron microscopy (EM) demonstrated intranuclear nonenveloped virus particles 80-120 nm in diameter consistent with a herpes type infection. Immunofluorescence staining demonstrated the presence of CMV antigens. Conditioned medium from the infected cells caused infection in RPE cells isolated from normal donors. Hybridization assay demonstrated the presence of CMV DNA and indicated that the time course of the infection was similar, but not identical to infection in MRC-5 and HEL cells. We conclude that cultured human RPE is a permissive host for CMV.

Abstract
Cytomegalovirus (CMV) retinitis is the major cause of visual loss in acquired immune deficiency syndrome (AIDS). Thirty-one patients with active CMV retinitis were treated with the new antiviral drug, Foscarnet (trisodium phosphonoformate). After a 3-week course of induction therapy, the retinitis improved in 29 of 31 patients (93.5%). Complete resolution of the retinitis was seen in 19 cases (61.3%). Ten patients had partial resolution (32.2%) and two (6.5%) failed to respond. After induction therapy, six patients were put on a low-dose maintenance regimen. All patients without maintenance therapy relapsed within 3 weeks after discontinuation of Foscarnet. The rate of relapse on maintenance therapy was 50% (3/6) within the first 5 weeks. The three other patients of Foscarnet maintenance did not relapse after a follow-up period of 12 weeks. In contrast to ganciclovir, Foscarnet did not induce neutropenia but it produced kidney toxicity that led to reversible renal insufficiency in three cases. Thus, Foscarnet appears to be a useful alternative to ganciclovir, particularly when combined with bone marrow toxic drugs, such as zidovudine (azidothymidine).

Abstract
We examined three patients with AIDS who had large, sharply demarcated areas of thinned retina consistent with inactive cytomegalovirus retinitis and who were not treated with ganciclovir. These lesions appeared identical to clinically inactive areas of cytomegalovirus retinitis after effective antiviral treatment. All patients were receiving azidothymidine or ribavirin, or both, which have activity against the human immunodeficiency virus and which may improve immune function. All patients also received oral acyclovir at doses ineffective against cytomegalovirus retinitis.

Abstract
The eyes of an AIDS patient with cytomegalovirus (CMV) retinitis and pneumonitis who died while receiving maintenance therapy with the antiviral agent 9-[2-hydroxy-1-(hydroxymethyl) ethoxymethyl] guanine (Ganciclovir) were obtained for pathological examination. While under treatment the patient had significant improvement but not complete regression of retinitis. Electron microscopic and immunofluorescent techniques revealed cytomegalovirus particles in the retina, sclera, iris, and ciliary body. These findings are consistent with a virostatic type of inhibition of CMV by this agent. They also suggest that CMV involvement in the eye and other organs may be more widespread than is clinically apparent in AIDS patients.

Abstract
Two groups of albino rabbits received an intravitreal injection of liposome-encapsulated trifluorothymidine. One group underwent a clearance study using high-performance liquid chromatography. The results of this study demonstrated a prolonged vitreal drug level within the range of ID50 for many strains of herpesvirus and human cytomegalovirus (CMV) at 28 days after injection. The eyes of another group were evaluated with preoperative and postoperative indirect ophthalmoscopy, electroretinography, and histologic examination. No retinal toxicity was found.

Abstract
Eighteen immunocompromised patients with cytomegalovirus (CMV) retinitis were treated with ganciclovir, an investigational antiviral drug. CMV retinitis in association with acquired immune deficiency syndrome (AIDS) developed in 17 patients; CMV retinitis developed in one patient after cardiac transplantation. Fourteen patients responded to ganciclovir treatment with improvement in CMV retinitis. In 11 patients, the response was classified as complete; in three patients, the response was partial. Continued improvement in the retinitis was often seen while the patient was on maintenance treatment. Maintenance ganciclovir therapy was required; relapse occurred in five of seven patients in whom ganciclovir treatment was interrupted. The major limiting toxic side effect of ganciclovir was neutropenia, which necessitated temporary discontinuation of ganciclovir in five patients but was reversible in all cases. Ganciclovir appears to be an effective therapy for CMV retinitis, but chronic maintenance therapy is required.

Abstract
A total of 66 eyes in 41 patients were treated for cytomegalovirus (CMV) retinitis with a new acyclic nucleoside, ganciclovir (BW B759U). At the completion of the short-term therapy period of 21 days, 87.7% of eyes had stabilized or improved. Seventy-two percent of eyes stabilized or improved during long-term home maintenance therapy. Leukopenia and increased liver function abnormalities were the most common adverse drug reactions seen in this series. Ganciclovir dramatically improved the quality of life in these patients, but clinical evidence suggests that it is a virostatic medication requiring indefinite long-term maintenance therapy.

Abstract
Viral infections are a frequent occurrence following transfusion of blood products. While generally benign, these infections are capable of causing significant morbidity and mortality. Therefore, it is prudent to follow several general approaches diligently to reduce the risks of these infections in patients undergoing transfusions of blood products. These suggested measures include the following: 1. Prescribe and administer blood and blood products only when absolutely needed. 2. Use volunteer blood donors only. 3. Avoid use of pooled blood products when possible. 4. Use only blood and blood products that have been appropriately tested for HBsAg and HIV. 5. Use ALT determinations to screen blood products and eliminate those with high level. 6. Avoid the use of clotting-factor concentrates but, if necessary, use only those which have been heat-treated. 7. Limit use of leukocyte transfusion. 8. Use only CMV seronegative blood and blood products or frozen deglycerolized red cells in patients at high risk for posttransfusion CMV infection.

Abstract
Seventeen patients with the acquired immune deficiency syndrome and cytomegalovirus retinitis were treated with the antiviral drug ganciclovir (9-[1,3-dihydroxy-2-propoxy-methyl]-guanine, DHPG). Eight eyes of five patients developed rhegmatogenous retinal detachment after initiation of treatment. Multiple breaks in areas of peripheral, healed, atrophic retina accounted for the detachments. All seven eyes that underwent surgery had extensive retinal detachments that were reattached with vitrectomy and silicone oil. Retinotomy and retinal tacks were necessary in two cases that were complicated by severe proliferative vitreoretinopathy. In the fellow eye of one patient, laser treatment was used prophylactically to wall off a peripheral patch of healed retinitis. Endoretinal biopsies and culture were taken in five eyes; evidence of persistent cytomegalovirus was seen in two cases despite concurrent and clinically effective antiviral therapy.

Abstract
A 15-month prospective study of 109 patients with the acquired immune deficiency syndrome (AIDS) or AIDS-related complex (ARC) was conducted. Cytomegalovirus (CMV) retinitis developed in 18 of these patients; they were treated with ganciclovir. Five other patients with CMV retinitis who were not part of the prospective study were also treated with ganciclovir. CMV retinitis frequently involved the peripheral retina. All 23 patients treated with ganciclovir showed clinical regression of retinitis, although breakthrough recurrence of CMV retinitis occurred in seven patients (30.4%) while on maintenance therapy with ganciclovir. During treatment, neutropenia (less than 1000 leukocytes/mm3) developed in three patients (13%). Ganciclovir is an effective means of therapy for CMV retinitis, but it must be given chronically to prevent reactivation. Breakthrough recurrences while on maintenance therapy are not uncommon, but can be successfully treated with more aggressive treatment with ganciclovir. In addition, the prognosis for survival of AIDS patients being treated with ganciclovir is improved when compared with that of untreated patients.

Abstract
Ganciclovir is a new antiviral compound (also called BW B759U, DHPG, BIOLF-62, and 2'NDG) that has been used for the treatment of cytomegalovirus (CMV) retinopathy in immunocompromised patients (bone marrow recipients or acquired immune deficiency syndrome [AIDS] victims). The authors studied the eyes of three AIDS patients with CMV retinopathy who died while receiving ganciclovir chemotherapy. Gross, microscopic, and ultrastructural studies of these cases showed varying degrees of retinal scarring and active CMV lesions at the margins of the scars. CMV antigens were localized in cells at all layers of retina at the border of the lesions and in isolated cells in a perivascular location within histologically normal appearing retina. These areas probably represent sites of recrudescence when the drug is discontinued. In situ hybridization using a cloned complementary DNA (cDNA) probe of human CMV corroborated the immunocytologic localization of the virus. Ultrastructural studies showed megalic syncytial cells containing mostly capsids exclusively in the cell nucleus. The cytoplasmic electron-dense membrane-bound bodies that have characterized untreated cases of CMV retinopathy were absent in the treated cases. An attempt to isolate CMV in tissue culture from the vitreous and retina of one of the cases yielded a negative result. Our results indicate that ganciclovir does not effectively eliminate CMV from the retina nor does it suppress expression of all viral genes. Ganciclovir appears to function by limiting viral DNA synthesis and subsequent packaging of viral DNA into infectious units, thereby acting as a virostatic chemotherapeutic agent.

Abstract
We describe a 67-year-old white man with Wegener's granulomatosis who was treated with cyclophosphamide, then with azathioprine, and who subsequently developed cytomegalovirus retinitis. The patient initially improved on a course of adenine arabinosine, but his retinitis has progressed, despite discontinuation of immunosuppressive therapy. We show that cytomegalovirus retinitis does occur in patients with rheumatic diseases who receive immunosuppressive therapy.

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 studied two blind eyes enucleated during the active phase of the acute retinal necrosis syndrome. Both eyes showed similar histopathologic findings of necrotizing retinitis, retinal arteritis, and optic neuropathy. A virus morphologically consistent with a herpes group virus was found on electron microscopy and immunocytopathologic stains showed this virus to be varicella zoster in both cases. Varicella zoster virus was cultured from the vitreous of one of the eyes. We conclude that varicella zoster virus retinal infection is a cause of the acute retinal necrosis syndrome.

Abstract
Six patients (all male, five homosexual and one bisexual, 23 to 48 years old) with the acquired immune deficiency syndrome (AIDS) who had cytomegalovirus retinitis were treated with a new antiviral drug as a part of a prospective open-labeled trial for serious cytomegalovirus infections. The drug, 9-[2-hydroxy-1-(hydroxymethyl)ethoxymethyl] guanine (referred to as dihydroxy propoxymethyl guanine), a new acyclic nucleoside antiviral agent similar in structure to acyclovir, produced positive results. These patients treated with dihydroxy propoxymethyl guanine (2.5 mg/kg of body weight every eight hours) showed regression and often disappearance of the lesions of cytomegalovirus retinitis during and for several weeks after therapy, usually with concomitant resolution of viral shedding. The cytomegalovirus retinitis recurred in four patients (the other two were lost to follow-up), but retreatment usually led to remission. Adverse drug toxicity (reversible granulocytopenia) occurred in two patients.

Abstract
Autopsy findings of 133 patients who died following fungemia or with invasive fungal infection were reviewed. Common clinical factors included antibiotic therapy, chemotherapy, corticosteroid administration, hyperalimentation, malignancy, and bone marrow transplantation. Fungal infection was seldom diagnosed antemortem and fungemia was detected in only 24 patients (18%). Ocular involvement occurred in 14 patients (Candida 11, Aspergillus 2, and Cryptococcus 1). The eye was the fifth most commonly involved organ at autopsy among patients with candida infection. Ocular involvement occurred with a significantly greater frequency in patients with Candida tropicalis than with Candida albicans infections (P less than 0.05). Although only about 10% of patients with fungal infections had ocular involvement, all those with ocular lesions had widely disseminated disease. Realizing the potential toxicity of antifungal therapy, we recommend that screening ophthalmologic examinations be performed on patients with fungemia or patients at high risk for development of fungal infection. The presence of ocular lesions consistent with fungal disease, in the appropriate setting, is a strong indication for investigation of possible systemic fungal infection and therapy once a definitive diagnosis is established.

Abstract
A gross, light, and electron microscopic study of the eyes from 35 consecutive autopsy cases of the acquired immune deficiency syndrome revealed cotton-wool spots (71% of cases), retinal hemorrhage in areas without cytomegalovirus infection (40%), cytomegalovirus retinitis (34%) with associated retinal detachment, Roth's spots (23%), retinal microaneurysms (20%), papilledema (14%), conjunctival Kaposi's sarcoma (9%), cryptococcal chorioretinitis (6%), Mycobacterium avium-intracellulare in retina and in choroidal granulomas (6%), ischemic maculopathy (6%), bilateral keratitis (3%), and herpes simplex retinitis (3%). Ocular infection with candida or toxoplasmosis were not found in this autopsy series. Immunocytologic studies demonstrated deposition of immunoglobulins in arteriolar walls, consistent with immune complex mediated disease. Ultrastructural studies showed a vasculopathy in the areas near cotton-wool spots. A mechanism is proposed linking the deposition of immune complexes with subsequent small vessel lesions, ischemia, cotton-wool spots and later spread of cytomegalovirus to retina via damaged vascular endothelium.

Abstract
An immunoperoxidase technique was utilized to identify herpes simplex type I viral antigens in the retina, optic nerve and brain of an adult with herpetic retinitis and encephalitis. Viral antigens were demonstrated in all layers of retina, retinal pigment epithelium and to a lesser extent, in choroid. Oligodendroglia in the right optic nerve and neuronal and glial cells in the grey and white matter of the left frontal, inferior parietal and temporal lobes of the brain also expressed herpes simplex antigens. The sensitive immunoperoxidase method allowed detection of viral antigens in many cells without intranuclear inclusions or surrounding inflammation, and thereby added valuable information regarding the anatomic and cellular localization of herpetic infection. The clinicopathologic features that characterize herpes simplex retinitis in the adult are compared to cytomegalovirus retinopathy.

Abstract
We present a case of bilateral herpes simplex and cytomegalovirus retinitis and concurrent encephalitis following acyclovir therapy in a homosexual male with the acquired immune deficiency syndrome (AIDS). At autopsy, herpes simplex virus antigens were readily detected in all retinal layers, retinal pigment epithelium, and choriocapillaris, using an immunoperoxidase technique, whereas herpes simplex antigens in the brain were localized in restricted foci of vascular and subependymal parenchymal cells. Cytomegalovirus antigens were identified in cells in all layers of retina, in retinal pigment epithelium, and in subependymal parenchymal cells in the brain. No cytomegalovirus antigens were detected in any vascular endothelium, in choroid, or anterior to the ora serrata. The widespread expression of herpes simplex virus antigens in this patient's retinas is in marked contrast to the restricted foci of herpes simplex antigens limited to the subependymal region of the brain, and is similar to that seen in murine models of herpes simplex retinitis produced by acyclovir-resistant viral mutants.

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.
