Abstract
BACKGROUND/PURPOSE The purpose of this study was to describe a case of severe occlusive vasculitis that led to a diagnosis of AIDS in a previously healthy middle-aged man. METHODS Multimodal imaging including widefield fundus photography, spectral domain optical coherence tomography, and widefield fluorescein angiography was performed. RESULTS A healthy 46-year-old man presented with sudden onset vision loss in his left eye with an afferent pupillary defect. His examination revealed signs of retinal vascular disease in both eyes, with an ophthalmic artery occlusion in his affected left eye and a hemiretinal vein occlusion in his asymptomatic right eye. An extensive medical workup was significant for HIV positivity; he was ultimately diagnosed with AIDS, and ocular findings were attributed to an associated occlusive vasculitis. He developed anterior segment neovascularization in the left eye for which he received intravitreal bevacizumab and panretinal photocoagulation. He ultimately required cyclophotocoagulation in the left eye for poorly controlled intraocular pressure in the setting of neovascular glaucoma. CONCLUSION Although HIV is most classically associated with a retinal microangiopathy, testing should be considered in cases of occlusive retinal vasculitis because it is a rare cause of such findings.

Retinal Involvement in COVID-19: Results From a Prospective Retina Screening Program in the Acute and Convalescent Phase. Front Med (Lausanne) 2021; 8:681942. [PMID: 34249972 PMCID: PMC8264127 DOI: 10.3389/fmed.2021.681942] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Accepted: 05/14/2021] [Indexed: 12/23/2022] Open
Abstract
Objective: To detect retinal involvement in coronavirus disease 2019 (COVID-19) patients in acute and convalescent phase by their fundus screening. Methods: In a prospective, cross-sectional, observational study (July–November 2020), 235 patients (142 acute and 93 convalescent phase) underwent fundus screening in a tertiary care center in North India. For convalescent phase, “hospitalized” patients (73) were screened at least 2 weeks after hospital discharge, and “home-isolated” patients (20) were screened 17 days after symptom onset/COVID-19 testing. Results: None in acute phase showed any retinal lesion that could be attributed exclusively to COVID-19. Five patients (5.38%) in convalescent phase had cotton wool spots (CWSs) with/without retinal hemorrhage, with no other retinal finding, and no visual symptoms, seen at a median of 30 days from COVID-19 diagnosis. Conclusions: CWSs (and retinal hemorrhages) were an incidental finding in COVID-19, detected only in the convalescent phase. These patients were much older (median age = 69 years) than the average age of our sample and had systemic comorbidities (diabetes mellitus, hypertension, etc.). We propose the term “COVID-19 retinopathy” to denote the presence of CWSs at the posterior pole, occasionally associated with intraretinal hemorrhages, in the absence of ocular inflammation in patients with a history of COVID-19 disease.

Abstract
Purpose: Overview of the evolving epidemiology of human immunodeficiency virus (HIV)-related ocular disease over time. Method: Narrative review. Results: HIV enhances susceptibility to opportunistic eye infections, has direct pathogenic effects, and places patients at risk of immune recovery inflammatory syndromes in previously infected eyes after starting highly-active antiretroviral therapy (HAART). Widespread availability of HAART has resulted in a decrease of infectious ocular conditions such as cytomegalovirus retinitis, toxoplasmic retinitis, squamous cell carcinoma of the conjunctiva, and microvascular retinopathy. However, large coexisting burdens of tuberculosis, herpesvirus infection and syphilis (among others) continue to contribute to the burden of ocular disease, especially in low-resource settings. Growing risks of cataract, retinopathy and retinal nerve fiber thinning can affect patients with chronic HIV on HAART; thought due to chronic inflammation and immune activation. Conclusion: The changing epidemic of ocular disease in HIV-infected patients warrants close monitoring and identification of interventions that can help reduce the imminent burden of disease.

Abstract
The relationship between retinal microangiopathy and some features of human immunodeficiency virus (HIV) infection such as HIV antigenemia, antibodies to the viral proteins, T lymphocyte subsets, were studied in 71 patients with acquired immunodeficiency syndrome (AIDS). The absence of antibodies to the HIV p24 protein was significantly related to retinal microangiopathy (p = 0.0051) and more closely to retinal cotton-wool spots (p = 0.0007); the combination of positive antigenemia with the absence of antibodies to p24, which is typical of the later phases of HIV infection, was found in a larger percentage of patients with cotton-wool spots (p = 0.0013) than in subjects with every sign of microangiopathy (p = 0.0546). T-helper (CD4+) cells count below 200 cells/mm3 was also detected in a higher percentage of patients with HIV-related retinal microangiopathy (p = 0.009). These findings suggest that retinal microangiopathy and especially retinal cotton-wool spots are related to the progression of immunodeficiency.

Abstract
In Portugal, the prevalence of human immunodeficiency virus type 2 (HIV-2) seropositivity is higher than in other European countries or North America. Recent literature data points out a possible difference on the pathogenic potential and on the natural history of HIV-1 and HIV-2, suggesting a lower virulence of HIV-2. Facing these hypothesis and the increasing number of HIV-2 cases, we analysed two infected groups HIV-1 and HIV-2, trying to correlate the ophthalmologic lesions present in both populations and searching for a difference in the clinical presentation of the ocular disorder. We studied prospectively 214 patients with HIV infection at several stages, 83% HIV-1 and 17% HIV-2. Ocular manifestations were present in both populations with a significant prevalence in HIV-1 (48%), compared to HIV-2 (19%) (p<0.005). The ophthalmologic pathology found, particularly noninfectious retinopathy, infectious retinitis and neuro-ophthalmic disorders, were considered important for the disease's diagnosis and prognosis. All these ophthalmic findings were present in the HIV-1 population. In the HIV-2 group the most frequent lesion was noninfectious retinopathy. Within each group, HIV-1 and HIV-2, the comparison of the survival between AIDS patients with and without ocular lesions, revealed a significant shorter survival time in those with ocular pathology (p<0.001 and p<0.05). There seems to exist a certain analogy in clinical expression in both groups, although it is possible to admit a lower severity in ocular involvement in patients infected by HIV-2.

Abstract
AIM To compare the clinical manifestation of cytomegalovirus (CMV) retinitis and microvascular retinopathy (MVR) in patients with acquired immunodeficiency syndrome (AIDS) in China. METHODS A total of 93 consecutive patients with AIDS, including 41 cases of CMV retinitis and 52 cases of MVR were retrospectively reviewed. Highly active antiretroviral therapy (HAART) status was recorded. HIV and CMV immunoassay were also tested. CD4+ T-lymphocyte count and blood CMV-DNA test were performed in all patients. Aqueous humor CMV-DNA test was completed in 39 patients. Ophthalmological examinations including best corrected visual acuity (BCVA, by International Standard Vision Chart), intraocular pressure (IOP), slit-lamp biomicroscopy, indirect ophthalmoscopy were performed. RESULTS In MVR group, the anterior segment examination was normal in all patients with a mean BCVA of 0.93±0.13. Blood CMV-DNA was 0 (0, 269 000) and 42 patients (80.77%) did not receive HAART. In CMV retinitis group, 13 patients (31.71%) had anterior segment abnormality. The mean BCVA was 0.64±0.35 and blood CMV-DNA was 3470 (0, 1 450 000). Nineteen patients (46.34%) had not received HAART. MVR group and CMV retinitis group the positive rates of aqueous CMV-DNA were 0 and 50%, respectively. Two patients with MVR progressed to CMV retinitis during the follow-up period. CONCLUSION In comparison of CMV, patients with MVR have relatively mild visual function impairment. Careful ophthalmological examination and close follow-up are mandatory, especially for patients who have systemic complications, positive CMV-DNA test and without received HAART.

Abstract
We report a case of peripheral retinal neovascularization and vitreous hemorrhage in the setting of HIV retinopathy that can serve to extend the clinical spectrum of this condition. A 53-year-old African-American woman with AIDS was referred for decreased vision in the left eye and was found to have peripheral retinal neovascularization and vitreous hemorrhage. She had a workup that was negative for etiologies of retinal ischemia. Peripheral laser photocoagulation was used to treat areas of nonperfusion. To our knowledge, this is the first reported case of peripheral retinal neovascularization and vitreous hemorrhage in the setting of HIV retinopathy, and it can serve to extend the clinical spectrum of this condition.

Abstract
PURPOSE The purpose of this study was to determine the cytokine-related pathogenesis of human immunodeficiency virus retinopathy in human autopsy eyes. METHODS Fresh autopsy eyes were procured from clinically diagnosed patients with acquired immunodeficiency syndrome who had died as a result of disease-related complications; eyes were immediately immersed in RNAlater. Clean 2-mm trephines were used to punch individual pathologic retina in areas of cotton-wool spots and control punches. Total RNA was extracted using the TRIzol extraction protocol, and the optimal density of the RNA was measured at an optical density of 260 nm. [Delta]Ct (cytokine) values were calculated using the comparative cytokine analysis method. The results are expressed as a mean fold modulation and as a statistical comparison of Ct values controlling for retinal areas without a lesion in the same eye. RESULTS The fold modulations and the statistical comparisons of the cytokines studied in tissues from cotton-wool spots and control retina, respectively, regulated on activation normal T cell expressed and secreted (RANTES), macrophage inflammatory protein 1beta, macrophage inflammatory protein 1alpha (5.32x, P = 0.04), and Bcl-2-associated X protein (1.24x, P = 0.05) had a marked elevation of fold modulation and were statistically significant compared with control tissue. Interleukin-8 (1.09x, P = 0.18), interleukin-4, and interleukin-10 (2.7x, P = 0.30) were not significantly expressed in cotton-wool spots. CONCLUSION Certain inflammatory human immunodeficiency virus-associated and apoptotic cytokines are expressed in cotton-wool spots in eyes with human immunodeficiency virus retinopathy.

Abstract
PURPOSE Patients infected with the human immunodeficiency virus (HIV) develop noninfectious retinopathy characterized by retinal cotton wool spots (CWS) and microvascular abnormalities. Ophthalmoscopically, CWS fade with time. We hypothesized that structural changes should be permanent and possibly visible well after ophthalmoscopic resolution. We used simultaneous spectral domain optical coherence tomography (SD-OCT)/scanning laser ophthalmoscope (SLO) to allow colocalization of the lesions and determine the extent and location of residual damage after ophthalmoscopic resolution of the lesions. DESIGN Retrospective, noninterventional case series. PARTICIPANTS Eight eyes of 7 HIV patients with 19 resolved retinal CWS. METHODS Nineteen retinal CWS were imaged between 2 and 16 years (median, 7.84) after the acute lesions using simultaneous SD-OCT and SLO examinations. The areas of the previous CWS were scanned by overlaying the color retinal image over the SLO image and scanning at high resolution in the horizontal plane through the resolved lesion. Each CWS lesion had a control area taken from the same eye within 2 disc diameters of the lesion. The thickness of each of the retinal layers was compared between lesions and control areas using a paired t-test with multitest correction. MAIN OUTCOME MEASURES Thickness of the retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), and outer nuclear layer (ONL). RESULTS The greatest loss of thickness was seen in the retinal GCL with a 43% reduction in thickness. There was a statistically significant thinning of the RNFL, GCL, IPL, INL, and OPL. The median thickness differences ranged from 5 to 7 microns. This difference was highly significant. Another striking finding was the displacement of the ONL toward the retinal surface resulting in an apparent increase in thickness of the ONL by >15% (median difference, 12 microns). CONCLUSIONS Our data, using ultrahigh resolution and high-speed SD-OCT/SLO, show and quantify the presence of permanent retinal destruction associated with retinal CWS in HIV disease.

Abstract
PURPOSE The widespread use of highly active antiretroviral therapy (HAART) has changed the clinical picture of HIV-associated eye disease. We evaluated the incidence of ocular manifestations of HIV infection since the introduction of HAART. METHODS Between January 1996 and December 2002, we examined 539 HIV-infected patients in our hospital. Follow-up of the patients was performed in case of ophthalmologic symptoms, regardless of current immunologic status, or for screening. RESULTS A total of 217 patients (40.3%) had HIV-associated eye disease. Of these patients, 42.0% had no eye symptoms. Fifty-eight (10.8%) of the 539 patients had cytomegalovirus (CMV) retinitis, most of whom had CMV retinitis before receiving HAART. Four patients developed immune-recovery uveitis. A total of 145 patients (26.9%) had HIV-related microangiopathy and 96 (17.8%) had dry-eye syndrome. CONCLUSION The introduction of HAART had a major impact on the medical history of patients with HIV-related eye disease with improved survival time and decreased morbidity.

Abstract
PURPOSE To evaluate the prevalence and risk factors for vision loss in patients with clinical or immunologic AIDS without infectious retinitis. DESIGN A prospective, multicenter cohort study of patients with AIDS. METHODS One thousand three hundred and fifty-one patients (2,671 eyes) at 19 clinical trials centers diagnosed with AIDS but without major ocular complications of HIV. Standardized measurements of visual acuity, automated perimetry, and contrast sensitivity were analyzed and correlated with measurements of patients' health and medical data relating to HIV infection. We evaluated correlations between vision function testing and HIV-related risk factors and medical testing. RESULTS There were significant (P<.05) associations between measures of decreasing vision function and indices of increasing disease severity, including Karnofsky score and hemoglobin. A significant relationship was seen between low-contrast sensitivity and decreasing levels of CD4+ T-cell count. Three percent of eyes had a visual acuity worse than 20/40 Snellen equivalents, which was significantly associated with a history of opportunistic infections and low Karnofsky score. When compared with external groups with normal vision, 39% of eyes had abnormal mean deviation on automated perimetry, 33% had abnormal pattern standard deviation, and 12% of eyes had low contrast sensitivity. CONCLUSIONS This study confirms that visual dysfunction is common in patients with AIDS but without retinitis. The most prevalent visual dysfunction is loss of visual field; nearly 40% of patients have some abnormal visual field. There is an association between general disease severity and less access to care and vision loss. The pathophysiology of this vision loss is unknown but is consistent with retinovascular disease or optic nerve disease.

Abstract
PURPOSE To assess the retinal nerve fiber layer thickness in children with human immunodeficiency virus disease without cytomegalovirus retinitis or visual symptoms. METHODS Thirty-eight eyes of 19 human immunodeficiency virus-positive children (group A) with visual acuity of 20/20 or better, normal color vision testing and no ophthalmoscopically detectable disorders were prospectively examined. All subjects of group A had no history of cytomegalovirus retinitis and CD4 counts consistently above 100. Patients in group B (40 eyes of 21 patients) were human immunodeficiency virus-negative age-matched control subjects. Thickness of retinal nerve fiber layer along a 3.4-mm-diameter circle centered on the optic nerve head was evaluated using third-generation optical coherence tomography. CD8 T-lymphocyte count, presence of systemic infection, hemoglobin, hematocrit and serum beta-microglobulin levels were also recorded. RESULTS The mean overall retinal nerve fiber layer thickness in groups A and B were 89.2 +/- 24.01 microm and 102.82 +/- 29.168 microm (SD) respectively. The difference was considered extremely significant (P < 0.0001). Group A had significantly thinner average nerve fiber layer in temporal, nasal, superior and inferior retinal areas. CONCLUSIONS Significant retinal nerve fiber layer thinning occurs in human immunodeficiency virus-positive children with no visual impairment or ophthalmologic evidence or retinitis.

Abstract
PURPOSE Confocal laser scanning ophthalmoscopy (HRT; Heidelberg retinal tomograph II) and scanning laser polarimetry (GDx-variable corneal compensator [VCC]) were used to investigate whether early indicators of retinal nerve fiber layer (RNFL) thickness loss could be observed in patients infected with the human immunodeficiency virus (HIV) that had no associated retinopathy or optic neuropathy and were concomitantly receiving antiretroviral medications. METHODS HRT and GDx-VCC parameters obtained from a group of 13 HIV-positive subjects (n=26 eyes) on antiretroviral therapy examined with HRT, with a subgroup of six subjects (n=12 eyes) examined with both HRT and GDx-VCC, were compared with those of a matched HIV-negative control cohort (13 subjects, n=26 eyes) examined with HRT, with a subgroup of five subjects (n=10 eyes) examined with both HRT and GDx-VCC. We employed generalized estimating equations for statistical analysis. RESULTS Reduced mean values for the HRT height variation contour (p<0.045) and HRT mean RNFL thickness (p<0.023) were observed in HIV-positive subjects controlling for age, sex, and race. A significantly reduced mean value corresponding to the GDx-VCC superior maximum (p<0.014) and inferior maximum (p<0.016) were also observed for the HIV-positive cohort analyzed controlling for age, sex, and race. CONCLUSION HRT and GDx-VCC indicators of RNFL thickness appear to be significantly reduced in HIV-positive subjects without retinopathy or optic nerve disease using antiretroviral medication, suggesting RNFL loss occurs in this population of HIV-positive patients. The lack of correlation between CD4 counts, viral load, number of antiretroviral medications used, or years from diagnosis of HIV and RNFL thinning, suggests that possibly other factors associated with HIV infection may contribute to the apparent RNFL thickness loss.

Abstract
PURPOSE To describe the prevalence and incidence of reduced visual acuity in eyes of patients with AIDS and without cytomegalovirus (CMV) retinitis at enrollment and estimate the proportion of incident vision loss attributable to new-onset CMV retinitis in this cohort. DESIGN Multicenter prospective observational study. PARTICIPANTS Three thousand fourteen eyes of 1507 patients with AIDS and without CMV retinitis at enrollment. METHODS Medical history, ophthalmologic examination, and laboratory testing collected at enrollment and at follow-up visits every 6 months thereafter. MAIN OUTCOME MEASURES Loss of visual acuity across the < or =20/50 and < or =20/200 thresholds and doubling of the visual angle; potential causes of this vision loss. RESULTS For eyes of patients without CMV retinitis at enrollment, the proportions with best-corrected visual acuity of < or =20/50 and of < or =20/200 were 3.9% and 1.8%, respectively. The incidence rates of vision loss to < or =20/50, < or =20/200, and to a doubling of the visual angle were 1.5/100 eye-year (EY), 0.8/100 EY, and 2.1/100 EY, respectively. Approximately 40% of the incident vision loss was attributable to CMV retinitis diagnosed during the follow-up period, and approximately 25% was attributable to cataract. CONCLUSIONS Although the development of CMV retinitis was the most common reason for visual acuity loss in eyes of our patients with AIDS, it accounted for less than half of the vision loss in our population (approximately 40%). Newly diagnosed cataract during the follow-up period accounted for a substantial amount of incident vision loss as well.

Abstract
BACKGROUND Cytomegalovirus (CMV) retinitis was a much-feared visual complication of late-stage acquired immunodeficiency syndrome (AIDS) in the past. Its incidence has waned significantly owing to the benefits of potent antiretroviral combination therapy, which for many individuals has provided some degree of immune reconstitution and avoidance of opportunistic infections, particularly this blinding disease. CASE REPORT A 45-year-old white man with long-standing, multidrug-resistant human immunodeficiency virus (HIV) infection and severe immunodeficiency despite multiple antiretroviral drug regimens, presented to the eye clinic reporting decreased vision and spider web patterns in his left eye for the past week. Best-corrected visual acuity was 20/20 in the right (O.D.) and 20/25 in the left eye (O.S.). Dilated funduscopic examination of the left eye found vasculitis of the midperipheral inferonasal arcade in the midperiphery, with surrounding intraretinal hemorrhage and granular retinal necrosis. Diagnosis of cytomegalovirus retinitis was made, and the patient began induction therapy with oral valganciclovir 900 mg twice a day for 3 weeks. Maintenance therapy after retinitis stabilization was 900 mg every day until any observed recurrence of infection. Three months after complete resolution of the active retinitis, the patient returned to the clinic reporting new floaters of recent onset. A reactivation of the CMV retinitis warranted a reinduction with valganciclovir 900 mg orally twice a day for 3 weeks. CONCLUSION This case is illustrative of the efficacy and relative ease of administration of valganciclovir, the newest medication approved for treatment and maintenance of CMV retinitis. Despite his severe immunodeficiency, our patient tolerated the induction and maintenance therapy of oral valganciclovir well, and the CMV retinitis was stabilized and resolved with full recovery of visual acuity.

Abstract
BACKGROUND The aim of this article is to review the potential ocular and renal disorders in infectious diseases to which humans are susceptible and to determine prevalence of these diseases. METHODS Published cases of oculo-renal disorders associated with various infectious diseases were collected from the international literature by searching the MEDLINE database (PUBMED 1970-2004) for original reports and review articles published in English. Citations from papers retrieved were screened and retrieved papers were evaluated. RESULTS Based on the screened data, we propose a practical, structure-oriented checklist of such lesions divided into bacterial, viral, parasital, and fugal infections. CONCLUSION The oculorenal manifestations of infectious diseases may be flagrant or subtle. Awareness of the signs and symptoms of infections allows early recognition and prompt, appropriate management. The clinical presentation and relative frequency of those manifestations are reviewed.

Abstract
PURPOSE To describe the clinical features of retinal vascular occlusions (macrovasculopathy) and the proportion of affected patients with human immunodeficiency virus (HIV) infection. METHODS Retrospective chart review of all HIV-infected individuals with retinal vascular occlusions seen at a single tertiary care clinic between November 1983 and May 1998. RESULTS Retinal vascular occlusion was found in 38 eyes of 33 (1.3%) of the 2,484 consecutive patients examined. Of the 33 patients, 16 (48.5%) had central retinal vein occlusion, 9 (27.3%) had branch retinal vein occlusion, 4 (12.1%) had hemiretinal vein occlusion, and 1 each (3.0%) had central retinal arterial occlusion, branch retinal arterial occlusion, and combined hemiretinal vein occlusion and branch retinal artery occlusion. One patient (3.0%) had Purtscher-like retinopathy in one eye. Multiple regression analysis revealed that macrovasculopathy was associated with the presence of noninfectious retinal microvasculopathy (odds ratio, 5.76; 95% confidence interval, 2.59-12.80). Vision at the time of diagnosis ranged between 20/20 and no light perception. Twenty-five (75.8%) of the 33 patients had follow-up examinations for a mean period of 9.1 months. Ocular findings during follow-up included capillary dropout in 3 patients (11.5%), posterior pole neovascularization in 4 (15.4%), vitreous hemorrhage in 4 (15.4%), and optic atrophy in 6 (23.1%). Vision at the last eye examination ranged between 20/20 and no light perception and was 20/200 or worse in 15 (39.5%) of 38 eyes. CONCLUSIONS Patients with HIV infection have a small risk of retinal vascular occlusion, but complications and visual loss are common in affected patients. There is a strong association between noninfectious retinal microvasculopathy and retinal vein occlusions.

Abstract
Ocular involvement is a common complication of HIV infection. Since the late 1990s, widespread use of highly active antiretroviral therapy (HAART) has altered the spectrum, and reduced the incidence of ocular involvement in developed countries. The incidence of the most common ocular opportunistic infection, cytomegalovirus retinitis, has decreased tremendously. However, immune recovery uveitis secondary to HAART has emerged as a frequent visually threatening condition. Early diagnosis and treatment with periocular steroids is helpful in minimizing visual loss. Clinicians should also be aware that certain antimicrobial agents used to treat opportunistic infections in HIV-positive patients are associated with potentially serious ocular side effects. In developing countries, where most of the world's 40 million HIV-positive patients live, the spectrum and incidence of ocular involvement differ from those in developed countries. The lack of HAART availability is among the many causes of these differences, which may include nutritional factors, basic medical care availability and the levels of exposure to different infectious agents. These factors add to the already challenging task of treating ocular complications and preventing blindness in HIV-positive patients in developing countries.

Abstract
PURPOSE To assess retinal nerve fiber layer (RNFL) thickness in patients with human immunodeficiency virus (HIV) disease without cytomegalovirus retinitis (CMV). DESIGN A case-control study. METHODS The study included 113 eyes of 65 patients in one center. Thickness of RNFL along a 3.4-mm-diameter circle centered on the optic nerve head was evaluated using third-generation optical coherence tomography. Patients in group A (39 eyes of 22 patients) were human immunodeficiency virus-negative control subjects. Group B (36 eyes of 18 patients) was composed of HIV patients with no history of CMV retinitis and CD4 counts consistently above 100. Group C (38 eyes of 25 patients) comprised HIV patients with no history of CMV retinitis but a history of CD4 count less than 100 at some point lasting for at least 6 months. RESULTS The average RNFL thicknesses in groups A, B, and C were 103.33 +/- 8.50 microm, 103.30 +/- 9.28 microm, and 90.10 +/- 12.50 microm, respectively. Group C had significantly thinner overall RNFL than either of the groups A and B (Tukey-Kramer). This difference was most prominent in temporal, superior, and inferior retinal areas. No difference was in nasal retinal area, nor between groups A and B in any of the areas. CONCLUSIONS Significant RNFL thinning occurs in HIV patients without CMV retinitis and with low CD4 counts compared with the same subgroup of patients with CD4 count increased to above 100 and HIV-negative control subjects. Third-generation OCT may be useful in diagnosis of early subclinical HIV-associated visual functional loss.

Abstract
The ocular posterior segment manifestations of AIDS may be divided into four categories: retinal vasculopathy, unusual malignancies, neuro-ophthalmologic abnormalities, and opportunistic infections. Microvasculopathy is the most common manifestation. Opportunistic infections, particularly cytomegalovirus retinitis and progressive outer retinal necrosis, are the most likely to result in visual loss due to infection or subsequent retinal detachment. Diagnosis and treatment are guided by the particular conditions and immune status of the patient.

Abstract
PURPOSE To determine the relationship between AIDS retinal cotton wool spots (CWS) and neuropsychological impairment in HIV-positive individuals in the pre-HAART (highly active anti-retroviral therapy) era and the association between AIDS-related retinal CWS and neuropsychological impairment in HIV-positive patients not treated with HAART. METHODS A case-control analysis of prospectively acquired data in HIV-infected individuals who underwent prospective and longitudinal evaluations of retinal findings as well as neuropsychological testing was performed. Individuals underwent prospective retinal ophthalmic examinations with fundus photography of any retinal lesions. They also underwent periodic neuropsychological testing. The occurrence of retinal CWS was analyzed in relationship to neuropsychological impairment. RESULTS Thirty individuals with CWS were compared to 6o matched control AIDS patients. There was no association between either global clinical neuropsychological impairment or impairment in any of the five major domains tested and retinal CWS. There was an association between beta-2 microglobulin and CWS as well as an association between low CD4 T-cell count and the presence of retinal CWS. CONCLUSIONS We found no association between retinovascular disease and neurocognitive impairment in this case-control study. Retinal CWS in HIV disease are related to higher serum beta-2 microglobulin levels and lower CD4 T-cell counts, suggesting that these lesions are related to HIV disease progression but may be caused by a pathological process independent of CNS disease.

Abstract
Invasive bacterial and candidal infections are known to involve the retina, but the natural history of the retinal lesions and the utility of ophthalmologic consultation in the critical care setting as a diagnostic tool are not well understood. We 1) performed weekly funduscopic examinations on 77 medical and surgical patients in intensive care units (ICUs), 2) analyzed results of serial ocular examinations in 180 non-neutropenic patients with candidemia, and 3) reviewed the English literature on the association of retinal lesions with disseminated bacterial or candidal infection (DBCI). We found that 15 (19%) of the ICU patients had retinal lesions consistent with DBCI. Of these 15, 1 had clearly sepsis-related retinal lesions, while 13 (87%) had 1 or more systemic disease that could have explained their retinal findings (6 diabetic retinopathy; 2 human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) retinopathy; 2 hypertensive retinopathy; 1 hemolytic uremic syndrome, and 1 leukemia). Multivariate analysis revealed that systemic disease (odds ratio 8.37, 95% confidence intervals: 3.24-21.56) independently correlated with the presence of retinal lesions while DBCI, trauma, hyperalimentation, and transfusion of blood products were not independently predictive in any analysis. Twenty of the 180 (15%) candidemic patients had retinal lesions. Two (1%) had classic 3-dimensional white lesions with vitreal extension, and 5 (2.7%) had chorioretinal lesions without vitreal haziness. Notably, 10% of patients had superficial retinal hemorrhages and/or cotton wool spots that could have been due to either candidemia or a systemic disease (diabetes, hypertension, renal failure, closed head trauma). Concurrent bacteremia occurred in 3 of the 27 patients with eye lesions. Retinal lesions resolved in a mean of 33 days. None of the patients had symptoms at the time of the retinal finding. We found 3 studies that prospectively assessed retinal lesions in bacteremic patients. The frequency of retinal lesions in these series varied from 12% to 26%, with the most common lesions being cotton wool spots followed by superficial retinal hemorrhages. White-centered hemorrhages were seen in about 15% +/- 2 of bacteremic patients. Five studies prospectively evaluated candidemic patients for Candida endophthalmitis. These studies observed rates from 0% to 78% for lesions consistent with candidal endophthalmitis. Most studies performed recently found that nonspecific lesions such as cotton wool spots or superficial retinal hemorrhages occurred with a frequency of 11% to 20%. The availability of less toxic antifungal agents, more frequent use of empirical therapy, and the trend to early treatment may be altering the frequency of this complication. Observation of a classic 3-dimensional retina-based vitreal inflammatory process is virtually diagnostic of endogenous endophthalmitis due to Candida spp., but such lesions are relatively uncommon. Conversely, nonspecific lesions that could be due to bacterial or candidal endophthalmitis (cotton wool spots, retinal hemorrhages, and Roth spots) are seen frequently. These lesions are most often due to an underlying systemic disease rather than an infection. Serial examinations provide the best evidence that a given lesion is due to an intercurrent infection. The current low rate of vitreal extension of retinal process appears to be due to the high rate of empirical or therapeutic use of antifungal agents in high-risk patient groups. Ophthalmoscopy should be performed in patients with known candidemia. However, ophthalmoscopic examination seems to have little value in assisting with the discovery of occult disseminated candidiasis or bacterial infection.

Abstract
PURPOSE To evaluate the prevalence of retinal microangiopathy in human immunodeficiency virus (HIV)-1-infected patients and its association with virologic, immunologic, and sociodemographic parameters. DESIGN Single-center cross-sectional study. PARTICIPANTS One hundred eighty-eight HIV-1-positive individuals from a single outpatient clinic. METHODS Human immunodeficiency virus-positive patients were screened for signs of HIV-associated retinal angiopathy. Plasma HIV-1 RNA and CD4-positive cell counts were monitored within 3 months of the ophthalmologic assessment. The absence or presence of angiopathy or of opportunistic viral retinitis was then correlated to data respecting CD4-positive cell count, plasma viral load of HIV-1, and sociodemographic parameters. MAIN OUTCOME MEASURES Association between CD4-positive cell count, HIV-1 plasma viral load, sociodemographic parameters, and the manifestation of retinal microangiopathy. RESULTS At the baseline consultation, 130 (69%) patients exhibited no retinal pathologic features, 45 (24%) manifested retinal angiopathy, and 13 (7%) had opportunistic viral retinitis. In univariate analysis, retinal angiopathy was associated with lower CD4-positive cell count and higher HIV-1 plasma viral load. In a multivariate logistic model, the presence of retinal microangiopathy was associated with higher age (P = 0.02) and higher viral load of HIV-1 (P < 0.005), but not with lower CD4 cell counts (P > 0.05). CONCLUSIONS Human immunodeficiency virus-associated retinal microangiopathy is likely a multifactorial condition. Its presence is associated with higher age and higher replication of HIV-1 as measured by plasma HIV-1 RNA levels. In contrast to opportunistic infectious retinitis, the degree of immunodeficiency does not seem to be independently correlated with retinal angiopathy.

Abstract
This survey reviews selected medical disorders in which the ophthalmologist has a unique opportunity of anticipating the existence of asymptomatic, life-threatening disease simply by recognizing that certain benign conditions involving the eye or adnexa represent clues to occult non-ocular cancer and other neoplasias. Having knowledge that these clues are associated with specific types of neoplasia, the ophthalmologist can then initiate a goal-directed oncologic investigation designed to identify the underlying neoplasm with the hope of providing potentially life-saving therapy. The survey is organized to feature each clue separately. The clinical characteristics of the clue are described and illustrated with color photographs when possible. A discussion reviews associated malignancies and other important medical features. The survey begins with clues expressed anteriorly in the lids, progressively reviewing those clues located more posteriorly, concluding with clues involving the retinal pigment epithelium and choroid.

Abstract
PURPOSE To describe the characteristics of ischemic maculopathy in patients with human immunodeficiency virus (HIV) infection, as a means of understanding this uncommon disorder more fully. METHODS This is a multicenter, retrospective review of clinical data available for five HIV-infected patients who were given the diagnosis of ischemic maculopathy. RESULTS All cases had been diagnosed on the basis of fluorescein angiograms obtained after patients complained of vision loss. Four of the five patients had bilateral macular disease. Visual acuity at presentation in the nine affected eyes ranged from 20/20 to count fingers. Vision loss was gradual in both eyes of one patient and was abrupt in onset in seven eyes. Each of the seven eyes with abrupt vision loss had opacification of the superficial retina and/or intraretinal hemorrhages near the fovea. Fluorescein angiography revealed enlargement of the foveal avascular zone and mild staining of the juxtafoveal vessels in affected eyes. Six eyes had active or clinically inactive cytomegalovirus retinitis at presentation, and a seventh eye developed cytomegalovirus retinitis 2 weeks later. All patients were receiving anticytomegalovirus drugs when they developed visual symptoms. Visual acuity remained stable in five eyes, became worse in two eyes, and improved in two eyes; final visual acuity ranged from 20/25 to count fingers. CONCLUSIONS Ischemic maculopathy may cause profound and permanent vision loss in HIV-infected individuals. Fluorescein angiography should be considered in all HIV-infected patients with unexplained loss of vision. The pathogenesis of ischemic maculopathy remains unknown.

Abstract
PURPOSE Alterations of ocular blood flow may play a role in the pathophysiology of human immunodeficiency virus (HIV) related retinal microvasculopathy. In this study ocular blood flow was investigated in patients with HIV infection. DESIGN In a prospective, cross-sectional study ocular blood flow was measured in 37 eyes of consecutive HIV- infected persons and compared with the data of age-matched healthy controls. This sample size was calculated based on an alpha-error of 0.5 and a beta-error of 0.8. METHODS Macular white blood cell flow, fundus pulsation amplitude, and blood flow velocities in the retrobulbar vessels were measured with blue field entoptic technique, laser interferometry, and Doppler sonography, respectively. Immunologic and ophthalmologic status was evaluated from each patient. RESULTS Mean CD4+ cell count of the HIV-infected persons was 206.8 +/- 145.6 cells/mm(3). In five patients HIV-related retinopathy was observed. A significant reduction in leukocyte density was seen in HIV infected persons (82.2 +/- 23.4) as compared with the control group (102.0 +/- 28.4; P =.019). The resistive index in the central retinal artery was higher in HIV infected patients (0.77 +/- 0.05) as compared with the controls (0.74 +/- 0.04; P =.04). The other hemodynamic parameters were not different between groups. No correlation of flow parameters and CD4+ cell count or HIV-related retinopathy was observed. CONCLUSIONS Decreased macular leukocyte density was detected in HIV infected persons. Our study suggests that abnormal retinal hemodynamics in individuals infected with HIV may be involved in the pathogenesis of HIV-related microvasculopathy.

Abstract
BACKGROUND Retinal cotton wool spots (CWS) have long been associated with many systemic diseases, including diabetes mellitus and infection with the human immunodeficiency virus (HIV). The pathogenesis of the diabetic CWS has been well established but is not clear in HIV disease. This study documents a morphological difference between cotton wool spots observed in diabetes mellitus and HIV infection. METHODS Electronic images of 47 diabetic CWS and 38 HIV CWS were compared in terms of eccentricity. Each CWS was enlarged, and its major and minor axes were determined. Eccentricity was determined by use of a simple ratio of major vs. minor axis. The eccentricity of these diabetic and HIV CWS were compared by use of the Mann-Whitney rank sum test to check for significance. RESULTS The HIV CWS was significantly more eccentric (p < or = 0.001), thus suggesting a different morphology than its diabetic counterpart. CONCLUSIONS There seems to be a significant difference in the morphology of the cotton wool spots observed in diabetes mellitus compared with those observed in HIV infection. This difference suggests that, at some level, the pathogeneses of these two CWS are not the same. Clinically, the practitioner should strongly suspect HIV disease in a patient with boomerang-shaped cotton wool spots.

Abstract
Ophthalmic manifestations of FeLV or FIV infection can occur in all ocular tissues and may be manifestations of direct viral effects or secondary to viral-related malignant transformation. Additionally, the manifestations of common feline ophthalmic pathogens may be more severe and poorly responsive to therapy because of the immunosuppressive effects of FeLV or FIV infection. Prompt diagnosis of underlying viral infection in cats with ophthalmic disease is paramount for accurate diagnosis and prognosis and is required for appropriate therapeutic decision making.

Abstract
PURPOSE To report the ocular findings in HIV-1 seropositive individuals and HIV-negative controls in a population-based cohort in rural Uganda. METHODS Participants were examined by an ophthalmologist, who was unaware of their HIV-status. RESULTS 238 participants were examined, 43 were HIV-1 prevalent cases (infected prior to 1990); 62 were HIV-1 incident cases and 133 were HIV-negative controls. Eleven of the HIV-positive participants had AIDS, and a further 8 had a CD4 count of less than 200 cells/mm3. Bilateral low vision was recorded in 9 participants and cataracts were the main cause of bilateral low vision. The mean intra-ocular pressure (IOP) was 12.6 mm Hg, and no association was found between IOP and CD4 lymphocyte count. Although significantly more HIV positives had some sign of intraocular inflammation compared to the negatives (p = 0.02) there was no significant linear trend in the HIV positives with decreasing CD4 count. Overall, 11 (26%) prevalent, 6 (10%) incident cases and 8 (6%) HIV-negatives controls had some evidence of intraocular inflammation, however, only one person had reduced visual acuity attributable to these lesions. Punctate epithelial erosions and keratic precipitates in the anterior chamber were seen significantly more frequently in HIV-positives compared to the HIV-negative controls. Cotton wool spots were not seen. CONCLUSIONS A substantial proportion of HIV-infected persons had ocular findings which may have been attributable to their infection, however in only one case did this result in reduced visual acuity. Although the ocular complications of AIDS seem to comprise a large extra element in the work load of tertiary care hospitals dealing with eye problems, on a population basis such cases are infrequent.

Abstract
AIMS To determine the prevalence of ocular manifestations in AIDS patients hospitalised in Bujumbura, Burundi, according to their CD4+ lymphocyte count, serological status for CMV and VZV, and general health status. METHODS Prospective study of 154 consecutive patients who underwent general and ophthalmological examinations, including dilated fundus examination. AIDS was diagnosed on the basis of Bangui criteria and HIV-1 seropositivity. CD4+ lymphocyte counts were determined by the Capcellia method. CMV and VZV antibodies were detected with ELISA methods. RESULTS The mean age was 37 (SD 9) years and 65% of the patients were male. Active tuberculosis was the most frequent underlying disease (61%). Almost all the patients (99%) were seropositive for CMV and VZV. Among the 115 patients for whom CD4+ lymphocyte counts were available, 86 (75%) had more than 100 cells x 10(6)/l. Ocular involvement comprised 16 cases of microangiopathy, six of opalescence of the anterior chamber, five of retinal perivasculitis, two of zoster ophthalmicus, two of viral retinitis, and one of opalescence of the vitreous. CONCLUSION In Africa, the prevalence of ocular involvement in HIV infection is far lower than in Europe and the United States, possibly because most African patients die before ocular opportunistic infections occur.

Abstract
PURPOSE To report two cases of retinal peripheral lesions in vertically HIV-infected children. METHODS Complete ophthalmological examinations were performed in both cases over a period of four years. RESULTS We found retinal peripheral lesions in four eyes of two patients who were referred to us for routine examination. Both cases showed focal, segmental and white patches around the vessel wall in the far periphery and at the equator. These findings hardly changed after 3.5 and 2.5 years of follow-up, respectively. We suppose the cause of these lesions is an immune-mediated reaction. CONCLUSIONS Even although there is a low incidence of retinal alterations in pediatric patients infected by HIV, we believe that complete and systematic ophthalmic examinations should be performed in these children.

Abstract
BACKGROUND Clinical reports suggest that ocular disease in infants and children vertically infected with human immunodeficiency virus (HIV) is different from that in adults. Pediatric patients with acquired immunodeficiency syndrome (AIDS) and HIV infection are being treated more aggressively and are living longer, but current literature on the incidence of AIDS-related ocular disease in vertically acquired HIV infection is limited. METHODS Thirty-three children with culture-positive, vertically acquired HIV infections were prospectively followed with ophthalmic examinations between September 1991 and August 1996 at the University of Massachusetts. Patients were categorized as having symptomatic or asymptomatic HIV disease according to the U.S. Centers for Disease Control and Prevention guidelines. Absolute CD4 counts and other measures of immune function were obtained. RESULTS The average length of follow-up was 30 months, and the average number of ophthalmic examinations per patient was 4.8. Ten patients developed ophthalmic findings. Nine of 18 (50%) patients with symptomatic AIDS disease developed ophthalmic findings. One of 15 asymptomatic HIV-infected patients developed ocular findings. Two patients with absolute CD4 counts less than 10 developed cytomegalovirus retinitis. CONCLUSIONS These results suggest that AIDS-related ophthalmic disease is less common in vertically infected children than in adult AIDS patients. It also supports intensified clinical surveillance for cytomegalovirus retinitis in children with end-stage disease and very low CD4 counts.

Abstract
OBJECTIVE The purpose of the study was to examine the incidence of ocular opportunistic infections among patients who are human immunodeficiency virus (HIV) positive compared to patients who are HIV negative. DESIGN The study design was a retrospective cohort study. PARTICIPANTS All patients were recruited from 1984 until 1995 at the San Francisco General Hospital. INTERVENTION Incidences for numerous diagnoses were compared among the exposure group (HIV positive) and nonexposed control group (HIV negative). MAIN OUTCOME MEASURES The diagnoses studied were cytomegalovirus (CMV) retinitis, herpes zoster ophthalmicus, Pneumocystis carinii choroidopathy, herpes simplex keratitis, Toxoplasma retinitis, fungal retinitis, ocular syphilis, and ocular lymphoma. RESULTS Among the HIV-positive pool, there were 1800 patient visits with a total of 5200 person-years of follow-up. Among the HIV-negative control pool, there were 48,200 patient visits with a total of 30,100 person-years of follow-up. Incidence rates were calculated using the product-limit method, and risk ratios were calculated using the Cox proportional hazards model. Incidence rate differences were calculated using the incidence density method. Among the outcomes studied, only CMV retinitis, herpes zoster ophthalmicus, and, to a lesser extent, Toxoplasma retinitis showed both an elevated risk ratio and rate difference among patients who were HIV positive compared to patients who were HIV negative. Of the other outcomes studied, either the risk ratio, rate difference, or both were similar among patients who were HIV positive compared to patients who were HIV negative. CONCLUSIONS Not all ocular infections seen in patients who are HIV positive should be considered opportunistic, because many occur with similar incidence among patients who are HIV negative. The biologic reasons for this will require further study.

Abstract
PURPOSE To report macular ischemia as a cause of decreased vision in a patient with acquired immunodeficiency syndrome (AIDS). METHODS A 50-year-old man with AIDS who had previously diagnosed human immunodeficiency virus retinopathy and peripheral cytomegalovirus retinitis was initially examined with decreased vision in both eyes. He underwent complete systemic and ocular evaluation, fundus photography, and fluorescein angiography. RESULT Fluorescein angiography disclosed irregular enlargement of the foveal avascular zone in both eyes. CONCLUSIONS Macular ischemia may cause decreased vision in patients with AIDS and can be detected by fluorescein angiography.

Abstract
HIV retinopathy, a noninfectious microangiopathy, is the most common ocular manifestation of HIV infection. Opportunistic infections, neoplasms, neuro-ophthalmic lesions, and drug-induced lesions may also cause ocular problems. Opportunistic ocular infections, particularly CMV retinitis, are a major cause of morbidity in patients with AIDS. Because of the underlying chronic and progressive immune dysfunction, the ocular symptoms, signs, clinical course, and treatment are often atypical and severe, requiring protracted medical therapy.

Abstract
PURPOSE To determine the extent of vision loss in a cross-sectional study of HIV-positive individuals who had no infectious retinopathy. METHODS Visual field loss was determined by computerized achromatic automated perimetry and short-wavelength automated perimetry in both eyes in 65 HIV-positive individuals without infectious retinopathy and in one randomly selected eye each in 57 age-matched normal controls. Results were analyzed using the global index of mean defect and the Glaucoma Hemifield Test, and significance was determined through analysis of variance, chi-square, and Tukey-Kramer tests. RESULTS We found that HIV-positive patients, compared with age-matched HIV-negative controls, demonstrated significant (at least P < .01) localized defects as well as an increased mean defect. The HIV-positive patients also had a significantly greater number of defective points, especially on short-wavelength automated perimetry, even while ophthalmoscopic examination and fundus photographs suggested that the retinas were normal. CONCLUSIONS There is a significant loss of visual function in HIV-positive individuals that is not the result of infectious retinopathies. The finding by short-wavelength perimetry of more severe defects suggests that the vision defects are not caused by attentional or other suprachiasmatic problems because the neurologic difficulty of both achromatic and short-wavelength perimetry is similar. The effects of this vision loss on the daily living and occupational tasks of this population require further study.

Abstract
AIMS/BACKGROUND Abnormal blood flow dynamics are believed to contribute to the development of retinal microvascular disease in patients infected with human immunodeficiency virus (HIV). In this study, the scanning laser ophthalmoscope (SLO) was used, combined with fluorescein angiography, to measure retinal blood flow indices in HIV seropositive patients. METHODS Arteriovenous passage time (AVP) and perifoveal capillary blood flow velocity (CFV) were measured in 23 HIV infected patients and 23 control subjects with SLO fluorescein angiography. RESULTS No significant difference in AVP was found between the two groups. However, CFV was significantly reduced in HIV infected patients (p = 0.013). CONCLUSION Patients infected with HIV show abnormal haemodynamics at the level of the perifoveal capillaries.

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.
