Abstract
Our article aims to report the ocular adverse effects of highly active antiretroviral therapy (HAART). In case 1, a 26-year-old male patient presented with a diminution of vision. In the absence of active cytomegalovirus (CMV) retinitis and a surge in CD4 count of more than 100 cells/µL over four months, he was diagnosed as a case of immune recovery uveitis (IRU). He responded well to topical steroids and cycloplegics. In case 2, while dry eye is a common adverse effect of HAART, our 53-year-old female patient progressed to a visually distressing stage of keratoconjunctivitis sicca. She responded to lubricants and continues to be on the same. In case 3, a 14-year-old female patient's vision succumbed to Stevens-Johnson syndrome due to nevirapine in the absence of timely intervention. Though uncommon, debilitating ocular adverse effects may be seen with HAART. Further studies and reporting are required for an increased awareness among physicians and patients.

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

Abstract
Intraocular inflammation in patients with human immunodeficiency virus (HIV) infection is commonly due to infectious uveitis. Ocular lesions due to opportunistic infections (OI) are the most common and have been described extensively in the pre highly active antiretroviral therapy (HAART) era. Many eye lesions were classified as acquired immunodeficiency syndrome (AIDS) defining illnesses. HAART-associated improvement in immunity of the individual has changed the pattern of incidence of these hitherto reported known lesions leading to a marked reduction in the occurrence of ocular OI. Newer ocular lesions and newer ocular manifestations of known agents have been noted. Immune recovery uveitis (IRU), the new menace, which occurs as part of immune recovery inflammatory syndrome (IRIS) in the eye, can present with significant ocular inflammation and can pose a diagnostic and therapeutic challenge. Balancing the treatment of inflammation with the risk of reactivation of OI is a task by itself. Ocular involvement in the HAART era can be due to the adverse effects of some systemic drugs used in the management of HIV/AIDS. Drug-associated retinal toxicity and other ocular side effects are being increasingly reported. In this review, we discuss the ocular manifestations in HIV patients and its varied presentations following the introduction of HAART, drug-associated lesions, and the current treatment guidelines.

Aggressive conjunctival Kaposi sarcoma as the initial manifestation of acquired immunodeficiency syndrome. Am J Ophthalmol Case Rep 2020; 19:100832. [PMID: 32715160 PMCID: PMC7376940 DOI: 10.1016/j.ajoc.2020.100832] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2018] [Revised: 06/04/2020] [Accepted: 07/10/2020] [Indexed: 12/04/2022] Open
Abstract
Purpose To report a case of Kaposi sarcoma in a patient with previously undiagnosed Human Immunodeficiency Virus (HIV) infection. Observations A 23-year-old male patient presented to the eye clinic with complaints of redness of his left eye for the past month. The patient had been seen one day prior to presentation in the emergency department for a neck mass and pneumonia. Exam was notable for a left hemorrhagic, nodular, bulbar conjunctival mass, a right hemorrhagic conjunctival lesion, and violaceous facial skin lesions. Due to suspicion for conjunctival Kaposi sarcoma, HIV and Acquired Immune Deficiency Syndrome (AIDS) serologies were obtained which returned positive. Biopsies of the ocular mass and axillary lymph nodes confirmed Kaposi sarcoma. The patient was started on anti-retroviral therapy and Doxorubicin. The left conjunctival mass initially progressed to cover most of his cornea but eventually regressed by 6 months. Conclusions and Importance Ocular involvement of Kaposi sarcoma as the initial manifestation of HIV/AIDS is rare with only a few reported cases. Since the advent of highly active antiretroviral therapy, conjunctival or adnexal Kaposi sarcoma is not commonly encountered by healthcare providers. Concern for Kaposi sarcoma of the conjunctiva in this patient led to the evaluation for HIV/AIDS. It is vital for all healthcare providers to have Kaposi sarcoma in the differential diagnosis of a hemorrhagic conjunctival or adnexal mass and be familiar with its association with HIV/AIDS. If suspected, appropriate counseling and testing should be performed.

Abstract
AIM To characterize anterior eye health and tear film characteristics in individuals with human immunodeficiency virus (HIV) undergoing anti-retroviral therapy. METHODS This cross-sectional study involved 35 adults, categorized as healthy controls (n = 18) or as HIV-positive patients (n = 17), with no history of opportunistic infection or current ocular fundus abnormalities. Participants underwent a comprehensive anterior eye assessment. Primary outcome measures were dry eye symptoms (Ocular Surface Disease Index survey), tear film osmolarity, and extent of meibomian gland dropout. Secondary outcomes measures were ocular redness, tear film stability, and ocular surface staining. Levels of 36 cytokines were assayed from basal tears using a multiplex bead array. RESULTS The HIV-positive group showed more extensive meibomian gland dropout relative to controls (mean ± SD, controls: 29.6 ± 5.8 versus 37.0 ± 13.9%, p = 0.045). The extent of meibomian gland dropout was negatively correlated with blood CD4 T-cell count (a marker of immunodeficiency) at diagnosis (r = -0.69, p = 0.006). All other tests of anterior ocular health, including dry eye symptom levels, were not significantly different between the groups. There were no significant inter-group differences for the 36 cytokines assayed in the tear film. CONCLUSIONS We find greater meibomian gland dropout in HIV-positive individuals that is related to disease severity at diagnosis. Given this feature predisposes to dry eye disease, it suggests the need for long-term studies of anterior eye health in people with HIV.

Abstract
The purpose of the study was to investigate the association between infectious agents and the development of cancer in the ocular adnexa. A comprehensive literary study was carried out, reviewing and summarizing previous reports on the topic. A broad range of malignancies of the ocular adnexa are associated with infectious agents. A strong association and possible causal relationship between the infectious agent and the development of ocular adnexal cancer are seen in Merkel cell carcinoma (Merkel cell polyomavirus), Burkitt lymphoma (Epstein-Barr virus) and Kaposi sarcoma (human herpesvirus 8). Infection with Chlamydia psittaci has been associated with the development of extranodal marginal zone B-cell lymphoma in Italy. Human papillomavirus infection has been associated with the development of squamous cell carcinomas of the ocular adnexa, although with a highly variable reported prevalence. By exploring the role of infectious agents in the ocular adnexa and the mechanism by which they contribute to oncogenesis, the diagnostics, management and prevention of these malignancies may also improve. Antibiotic treatment and vaccines against infectious agents may be valuable in future treatment. Additionally, the presence of infectious agents within the tumours may have a prognostic or predictive value.

Abstract
OBJECTIVES To evaluate corneal and anterior chamber morphology as measured by Pentacam HR in human immunodeficiency virus (HIV)-infected patients without opportunistic infections and to search for signs of accelerated aging. METHODS This prospective study included 41 eyes of 41 HIV-1-infected patients (study group) and 50 eyes of 50 healthy subjects (control group). Specular microscope and Pentacam HR were used for corneal and anterior chamber morphology evaluation. Corneal endothelial cell density (CECD), hexagonal cell ratio, coefficient of variation, corneal thickness, density and volume, maximum keratometry, anterior chamber volume (ACV), and anterior chamber depth (ACD) measurements were recorded for analysis. RESULTS The mean CD4 count was 428.3±231.9 (36-950) cells/mL, and the time since diagnosis was 27.5±34.1 months in the study group. The difference in anterior segment parameters was not significantly different between the study and the control groups (P>0.05). Age significantly correlated with CECD (r=-0.436, P=0.004), ACV (r=-0.570, P<0.001), ACD (r=-0.471, P=0.002), and corneal density (r=0.424, P=0.006) in the study group, whereas it did not show a significant correlation with any ocular parameters in the control group (Pearson correlation). CONCLUSION Corneal density, CECD, ACV, and ACD showed significant correlation with age in HIV-1-infected patients. Further studies are needed to show whether ocular parameters may serve as useful tools to monitor HIV-related accelerated aging.

Abstract
The structure and function of exocrine glands are negatively affected by human immunodeficiency virus (HIV) infection and its co-morbidities, including innate and adaptive immune responses. At the same time, exocrine function may also be influenced by pharmacotherapies directed at the infectious agents. Here, we briefly review the role of the salivary glands and lacrimal glands in normal physiology and exocrine pathogenesis within the context of HIV infection and acquired immune deficiency syndrome (AIDS), including the contribution of antiretroviral therapies on both. Subsequently, we discuss the impact of HIV infection and the types of antiretroviral therapy on disease management and therapy development efforts.

Abstract
Human immunodeficiency virus infection (HIV) is associated with a reduced T-helper (Th) 1 response, and vernal keratoconjunctivitis (VKC) occurs secondary to a heightened Th2 response. VKC has been reported to occur in patients with HIV. In all probability, a Th1–Th2 shift occurs in the immune response in progressive HIV patients with a decreasing CD4 count. This shift could be the probable cause for the initiation and gradual worsening of the VKC in our patient that corresponded to the dropping CD4 counts. VKC resolved only after a change in antiretroviral therapy for HIV that caused a demonstrable increase in the CD4 counts possibly by reversing the shift.

Abstract
Ocular surface squamous neoplasia (OSSN) refers to a spectrum of conjunctival and corneal epithelial tumors including dysplasia, carcinoma in situ, and invasive carcinoma. In this article, we discuss the current perspectives of OSSN associated with HIV infection, focusing mainly on the epidemiology, pathophysiology, clinical manifestations, diagnosis, and treatment of these tumors in patients with HIV. Upsurge in the incidence of OSSN with the HIV pandemic most severely affected sub-Saharan Africa, due to associated risk factors, such as human papilloma virus and solar ultraviolet exposure. OSSN has been reported as the first presenting sign of HIV/AIDS in 26%-86% cases, and seropositivity is noted in 38%-92% OSSN patients. Mean age at presentation of OSSN has dropped to the third to fourth decade in HIV-positive patients in developing countries. HIV-infected patients reveal large aggressive tumors, higher-grade malignancy, higher incidence of corneal, scleral, and orbital invasion, advanced-stage T4 tumors, higher need for extended enucleation/exenteration, and increased risk of tumor recurrence. Current management of OSSN in HIV-positive individuals is based on standard treatment guidelines described for OSSN in the general population, as there is little information available about various treatment modalities or their outcomes in patients with HIV. OSSN can occur at any time in the disease course of HIV/AIDS, and no significant trend has been discovered between CD4 count and grade of OSSN. Furthermore, the effect of highly active antiretroviral therapy on OSSN is controversial. The current recommendation is to conduct HIV screening in all cases presenting with OSSN to rule out undiagnosed HIV infection. Patient counseling is crucial, with emphasis on regular follow-up to address high recurrence rates and early presentation to an ophthalmologist for of any symptoms in the unaffected eye. Effective evidence-based interventions are needed to allow early diagnosis and treatment, as well as prevention of the disease.

Abstract
Human immunodeficiency virus (HIV) causes impairment to the human immune system which leads to immunocompromised conditions, including ocular complications. Several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae organ such as dry eye, blepharitis which reduce quality of life of patients. In present, potent antiretroviral therapies HAART (highly active antiretroviral therapy) has improved the length and quality of life which may lead to an increased prevalence of anterior segment ocular disorders. Hence, this study has been undertaken to identify the prevalence and associated factors of anterior segment and external ocular disorder in HIV infected patients in the era of HAART. A prospective descriptive cross sectional study was carried out in HIV positive patients conducted at the Department of Ophthalmology, Chiang Mai University Hospital, from February 2014 to October 2015. Detail history and ocular examination was carried out to examine for anterior segment and external ocular disorders. A total number of 363 patients were included for this prospective cross-sectional study. From the total of 363 patients, 123 patients had an anterior segment and external ocular disorder which account as the prevalence of 33.9%. The most common anterior segment manifestations was dry eye seen in 36 patients (9.9%), followed by posterior blepharitis (Meibomian gland dysfunction) seen in 23 patients (6.3%) and anterior blepharitis seen in 12 patients (3.3%). Other ocular complications included microvasculopathy, immune recovery uveitis, conjunctivitis, papilloma, anterior uveitis, corneal ulcer, nevus, trichiasis, molluscum contangiosum, Kaposi sarcoma, interstitial keratitis, conjunctival lymphangiectasia, dacryocystitis, vernal keratoconjunctivitis and eyelid penicilosis. In this study, the prevalance of anterior segment disorders was higher than in the preHAART era. Dry eye, blepharitis and uveitis were the top three most common anterior segment disorders in the HAART era. The statistical analysis showed no association between age, sex, CD4 count, duration of infection or receiving HAART and anterior segment disorders. Anterior segment abnormalities reduce the quality of life of patients, so ophthalmologists have to be aware and complete ocular examination should be performed in all HIV infected patients.

Abstract
A 10-year-old boy presented with painless, gradually increasing mass in right upper lid without preceding trauma for the past 2 months. On examination, the mass was bluish red, soft to firm in consistency which bleeds on touch. Contrast-enhanced CT showed a well-defined heterogeneously enhancing mass lesion without any continuity with the underlying bone or the orbital cavity. Complete excision of the mass was performed under general anaesthesia, subsequent histopathological examination showed findings consistent with an acquired variant of capillary haemangioma. At the end of 1 year, patient is cosmetically fine without any recurrence/morbidity.

A meta-analysis of published prevalence data estimated the impact of age and sex. Global mapping of prevalence was undertaken. The prevalence of DED ranged from 5 to 50%. The prevalence of signs was higher and more variable than symptoms. There were limited prevalence studies in youth and in populations south of the equator. The meta-analysis confirmed that prevalence increases with age, however signs showed a greater increase per decade than symptoms. Women have a higher prevalence of DED than men, although differences become significant only with age. Risk factors were categorized as modifiable/non-modifiable, and as consistent, probable or inconclusive. Asian ethnicity was a mostly consistent risk factor. The economic burden and impact of DED on vision, quality of life, work productivity, psychological and physical impact of pain, are considerable, particularly costs due to reduced work productivity. Questionnaires used to evaluate DED vary in their utility. Future research should establish the prevalence of disease of varying severity, the incidence in different populations and potential risk factors such as youth and digital device usage. Geospatial mapping might elucidate the impact of climate, environment and socioeconomic factors. Given the limited study of the natural history of treated and untreated DED, this remains an important area for future research.

HIV-infected individuals on long-term antiretroviral therapy are at higher risk for ocular disease. Epidemiol Infect 2017; 145:2520-2529.

Abstract
Introduction of antiretroviral therapy (ART) has dramatically reduced the incidence of infectious ocular diseases in human immunodeficiency virus (HIV)-infected individuals. However, the effects of long-term ART and chronic HIV infection on the eye are ill-defined. This study determined the occurrence and severity of ocular diseases among 342 participants in a rural South African setting: HIV-naïve (n = 105), HIV-infected ART-naïve (n = 16), HIV-infected on ART for 36 months (long-term ART; n = 165). More HIV-infected participants presented with an external eye condition, in particular blepharitis, than HIV-naïve individuals (18% vs. 7%; age-adjusted odds ratio (aOR) = 2·8, P < 0·05). Anterior segment conditions (particularly keratoconjunctivitis sicca and pterygium) were also more common (50% vs. 27%; aOR = 2·4; P < 0·01). Compared with individuals on short-term ART, participants receiving long-term ART were more likely to have clinically detectable cataract (57% vs. 38%; aOR = 2·2, P = 0·01) and posterior segment diseases, especially HIV retinopathy (30% vs. 11%; aOR = 3·4, P < 0·05). Finally, long-term ART was significantly associated with presence of HIV retinopathy (P < 0·01). These data implicate that ocular disease is more common and of more diverse etiology among HIV-infected individuals, especially those on long-term ART and suggest that regular ophthalmological monitoring of HIV-infected individuals on ART is warranted.

Abstract
PURPOSE To investigate the tear cytokine profile in HIV patients with dry eye disease (DED) and study the association between the severity of ocular inflammatory complications and tear cytokines levels. We postulate that HIV-mediated inflammation may be the underlying pathogenic mechanism for HIV-associated DED. METHODS The current prospective case-control study compared tear film cytokine profiles in DED patients with HIV infection (n=34) and age/gender-matched DED patients without HIV infection [controls (n=32)]. Participants were recruited from tertiary referral eye care centre and communicable disease clinics, Singapore. Ocular surface health was documented using tear film, Schirmer's test, corneal staining, and conjunctival injection measurements. Tear samples were collected using Schirmer's strips and analysed for the levels of 41 cytokines using Luminex bead assay. Logistic regression models were performed to determine correlation and significance. RESULTS Among the 41 cytokines analysed, statistically significant differences were observed in the mean values of epithelial growth factor (EGF), growth related oncogene (GRO) and interferon gamma-induced protein 10 (IP-10). EGF and IP-10 levels were higher and GRO levels were lower in the tears of DED patients with HIV infection compared to DED patients without HIV infection. No significant association was found between varying levels of ocular surface parameters and cytokine concentrations in HIV patients with DED (p>0.05). CONCLUSIONS EGF and IP-10 were significantly elevated and GRO levels were lower in the tear profile of HIV patients with DED compared to immunocompetent patients with DED. This study suggests a novel cytokine driven paradigm for ocular inflammatory complications of HIV infection. Additional studies in large organised cohorts can validate the results.

Martin P. Interventions for molluscum contagiosum in people infected with human immunodeficiency virus: a systematic review. Int J Dermatol 2016; 55:956-66. [PMID: 26991246 DOI: 10.1111/ijd.13267] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2015] [Revised: 11/02/2015] [Accepted: 11/18/2015] [Indexed: 11/27/2022]
Abstract
BACKGROUND Molluscum contagiosum (MC) is a viral skin disease that presents with white, painless papules with central umbilication. In immunocompent individuals, MC is usually a benign infection that resolves without intervention. In HIV positive people, symptoms of MC can be more severe. OBJECTIVE The aim of this systematic review is to analyze the literature on strategies for treating MC in people concomitantly infected with HIV and subsequently make recommendations on best management strategies for these people. METHOD Searches were conducted of the following electronic databases: MEDLINE, EMBASE, Cochrane Library, PubMed, LILACS, IndMED, Global Health, ClinicalTrials.Gov, and Current Controlled Trials. Grey literature was searched via the New York Academy of Medicine Grey Literature Report and Open Grey. References cited in previous reviews and references cited in studies identified as being possibly relevant were also reviewed. No language restrictions were imposed. Papers from 1980 to present were reviewed. RESULTS & DISCUSSION Thirteen studies were included in this review. Two papers were comparative studies, one of which was randomized and neither of which were blinded. Ten papers were observational studies with heterogeneous populations. One study was a multicentre cohort study. CONCLUSION Given the poor quality of study design, wide array of outcome variables, and lack of objective evidence, no specific recommendation can be made for the treatment of MC in people infected with HIV, other than the initiation of ART. Despite the good impact ART has made on prevalence of dermatologic disease, MC remains an important cause of morbidity in HIV positive populations.

Abstract
Purpose To investigate the patterns and risk factors of the ocular manifestations of acquired immunodeficiency syndrome (AIDS) and their correlation with CD4+ count in the era of highly active antiretroviral therapy (HAART). Methods This retrospective study examined 127 AIDS patients who presented to Soonchunhyang University Hospital. Data were collected from patient interviews, clinical examinations, and laboratory investigations. Ophthalmologic examinations included the best-corrected visual acuity, intraocular pressure, anterior segment and adnexal examination, and dilated fundus examination. Results Of the 127 patients with AIDS, 118 were on HAART and 9 were not. The mean CD4+ count was 266.7 ± 209.1 cells/µL. There were ocular manifestations in 61 patients (48.0%). The incidence of anterior segment manifestations was higher than posterior segment manifestations at 28.3% and 19.7%, respectively. The mean CD4+ count was significantly (p < 0.05) lower in the patients with posterior versus anterior segment ocular manifestations. The most common ocular manifestation was retinal microvasculopathy (15.0%), followed by keratoconjunctivitis sicca (14.2%), conjunctival microvasculopathy (9.4%), cytomegalovirus retinitis (3.1%), herpes zoster ophthalmicus (2.4%), and blepharitis (1.6%). Retinal microvasculopathy and cytomegalovirus retinitis were common in patients with CD4+ counts <200 cells/µL, while keratoconjunctivitis sicca and conjunctival microvasculopathy were common in patients with CD4+ counts of 200 to 499 cells/µL. There was a significant (p < 0.05) association between ocular manifestation and CD4+ count or age. Conclusions The introduction of HAART has changed the landscape of ocular presentations in patients with AIDS. In this study, anterior segment and external ocular manifestations occurred more frequently than posterior segment manifestations. Also, the mean CD4+ count was significantly lower in patients with posterior segment ocular manifestations versus anterior segment ocular manifestations. We found that CD4+ count and age >35 years were independent risk factors for developing ocular manifestations.

Abstract
PURPOSE To describe and compare the clinical presentation, treatment outcomes, and histopathologic features of ocular surface squamous neoplasia (OSSN) based on human immunodeficiency virus (HIV) status. DESIGN Case-control study. PARTICIPANTS A total of 200 patients with OSSN, of whom 83 (41%) had positive results for HIV and were classified as cases and 117 (59%) had negative results for HIV and were classified as controls. METHODS Enzyme-linked immunosorbent assay for HIV, conjuntival excision biopsy, extended enucleation, orbital exenteration. MAIN OUTCOME MEASURES Clinical features, treatment outcomes, and histopathologic characteristics. RESULTS The mean age at presentation of OSSN in both cases and controls was 40 years (median, 40 years; range, 13-65 years) and in controls was 40 years (median, 38 years; range, 15-80 years). On comparison of cases versus controls with OSSN, HIV-positive individuals had larger (12 vs. 8 mm; P < 0.001) and thicker (3.2 vs. 2.3 mm; P = 0.041) tumors, with a higher incidence of corneal (60% vs. 40%; P = 0.007), scleral (19% vs. 9%; P = 0.044), and orbital (13% vs. 3%; P = 0.019) invasion and a higher need for extended enucleation or exenteration (27% vs. 11%; P < 0.001). The bilateral presentation (11% vs. 4%; P = 0.13), need for lamellar sclerectomy (13% vs. 8%; P = 0.29), and tumor recurrence after primary treatment (30% vs. 20%; P = 0.12) was higher in HIV-positive cases compared with HIV-negative controls. However, these features were not statistically significant. Based on American Joint Committee on Cancer classification, T1 tumor was more common in controls (13% in cases vs. 35% in controls; P = 0.0009), and T4 tumor was more common in cases (13% in cases vs. 4% in controls; P = 0.019). None of the patients demonstrated systemic metastases or died of disease during a mean follow-up period of 10 months (median, 4 months; range, <1-75 months) in cases and 9 months (median, 4 months; range, <1-99 months) in controls. CONCLUSIONS Ocular surface squamous neoplasia in HIV-positive individuals is aggressive with larger and thicker tumors and with higher incidence of corneal, scleral, and orbital invasion. These patients are associated with poor ocular prognosis with higher need for extended enucleation, exenteration, or both.

Abstract
BACKGROUND/AIMS To determine the ophthalmic manifestations of HIV in a cohort of long-term survivors of perinatally acquired HIV. METHODS Twenty-two patients with perinatally acquired HIV who were aged ≥12 years were prospectively studied at a university clinic. They underwent complete ophthalmic examinations and fundus photography. Their medical histories, medications and CD4 counts were abstracted from the medical records. To evaluate for keratoconjunctivitis sicca, both HIV patients and 44 healthy controls (matched by age, gender and contact lens wear) underwent Schirmer testing and ocular surface staining. RESULTS Nine male and 13 female HIV patients with mean age of 16.6 years (SD, 3.4) were examined. Of the 22 HIV patients, 21 had been treated with highly active antiretroviral therapy (HAART). Only one patient had a CD4 count nadir of <200 cells/µL. The mean visual acuity of the eyes of the HIV subjects was 20/22 (SD, 1.6 lines). No patient had cytomegalovirus retinitis. Four of the 22 (18%) HIV patients had strabismus. HIV subjects and controls had similar rates of abnormal Schirmer (9% and 14%, p=0.62) and ocular staining scores (p=0.29). CONCLUSIONS In the post-HAART era, long-term survivors of perinatally acquired HIV exhibited little vision-threatening disease, but had a high prevalence of strabismus.

Abstract
Introduction. HIV/AIDS is one of twenty first century's biggest global challenges to mankind with protean manifestations affecting all organs of our body, not even sparing the eyes. The purpose of this study was to determine the pattern of ocular manifestations of HIV/AIDS and their correlation with CD4-count in a rural area of India. Methods. A hospital based observational cross-sectional study was done on 40 HIV-positive patients presenting to ART center with ocular complaints. Data were collected using face-to-face interview, clinical examination, slit lamp examination, fundus examination, and laboratory investigations. Results. Out of 40 patients, 21 were males and 19 were females with mean age of 38.75 ± 13.9 years. HIV retinopathy was the most common HIV-associated ophthalmic lesion while anterior uveitis was the most common anterior segment finding. Posterior segment lesions showed significant association (P < 0.05) with low CD4-count of the patient. CMV retinitis, retinal detachment, tubercular chorioretinitis, and acute retinal necrosis were all seen in patients with CD4-count less than 100 cells/mm3. Conclusions. HIV retinopathy, CMV retinitis, herpes zoster ophthalmicus, and anterior uveitis are common ocular manifestations associated with HIV infection. Low CD4-count is a risk as well as predictor for ocular manifestations. There needs to be awareness of ocular involvement among HIV infected individuals and an increased emphasis on regular ophthalmic examination.

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

Abstract
The mechanism through which human immunodeficiency virus (HIV) infection causes retinal disease and the loss of vision in AIDS patients remains unknown. The HIV-1 transactivator protein Tat (HIV-1 Tat) plays a pivotal role in the pathogenesis of HIV-1 infection and is often described as pleiotropic at different concentrations. In a previous study, we demonstrated that the HIV-1 Tat protein can disrupt the barrier function of retinal pigment epithelium (RPE) at 100 nM without affecting cell viability. The present study was undertaken to determine if HIV-1 Tat can induce RPE cell death at different concentrations and to determine the mechanism of any observed cell death. The results demonstrated that two RPE cell lines (ARPE-19 and D407) treated with Tat at concentrations of 200 nM and above exhibited reduced growth and apoptosis in a dose- and time-dependent manner. The disruption of mitochondrial outer membrane permeabilisation, the activation of caspase-3/7 and 9, the downregulation of Bcl-2, the upregulation of Bax, and the activation of p38 MAPK, ERK and NF-κB were all observed in HIV-1 Tat-treated RPE cells. When exposed to an inhibitor or transfected with siRNA of p38 MAPK and NF-κB, the level of cell death and deregulation of the expression of the apoptotic protein were attenuated. These effects were not observed with an ERK inhibitor or siRNA. Based on these results, we suggest that the induction of apoptosis by HIV-1 Tat in RPE cells may be mediated by p38 MAPK and NF-κB activation and involve the mitochondrial pathway. Therefore, these pathways may provide clues leading to novel therapeutic approaches for the retinopathy induced by HIV infection.

Abstract
OBJECTIVE Supporting non-HIV specialist professionals in the treatment of patients with urgent diseases resulting from HIV infection. METHODS These recommendations have been agreed by an expert panel from the National AIDS Plan Secretariat, the Spanish Society of Emergency Medicine, and the AIDS Study Group. A review has been made of the safety and efficacy results of clinical trials and cohort studies published in biomedical journals (PubMed and Embase) or presented at conferences. The strength of each recommendation (A, B, C) and the level of supporting evidence (I, II, III) are based on a modification of the criteria of the Infectious Diseases Society of America. RESULTS The data to be collected from the emergency medical history in order to recognize the patient at risk of HIV infection were specified. It stressed the basic knowledge of ART principles and its importance in terms of decline in morbidity and mortality of HIV+ patients and referring to the HIV specialist for follow-up, where appropriate, including drug interactions. Management of different emergency situations that may occur in patients with HIV infection is also mentioned. CONCLUSIONS The non-HIV specialist professional, will find the necessary tools to approach HIV patients with an emergency disease.

Abstract
The purpose of the study was to determine the prevalence of ocular diseases in human immunodeficiency virus (HIV) patients in Washington, DC in the era of highly active antiretroviral therapy (HAART). This was a cross-sectional study of patients with HIV who were seen by the ophthalmology consultation service between September 2003 and May 2011 at a single academic institution in Washington, DC. Medical history and ophthalmic findings were reviewed. Patients with complete laboratory data dated within 3 months of their presenting eye examination were included. Descriptive statistics were performed. The records of 151 patients were included in the final analysis. All patients had complete laboratory data dated within 3 months of their presenting eye examination. Sixty-eight (45 %) patients and fifty-eight (50 %) of those with a diagnosis of acquired immune deficiency syndrome (AIDS) were diagnosed with an HIV-related ophthalmic disease. The leading anterior segment disease was herpes zoster ophthalmicus and the leading posterior segment disease was HIV retinopathy. Of the 151 included patients, 78 (52 %) were receiving HAART at the time of the examination. Thirty-one (42 %) of those not receiving HAART were diagnosed with an HIV-related ophthalmic disease. In this study, we find that the overall prevalence of ocular disease has decreased since the introduction of HAART. However, HIV patients continue to be predisposed to developing ophthalmic disease at higher rates than the general population. Visual dysfunction remains an important source of morbidity in HIV patients, particularly in those with AIDS. Measures for improvement include increased communication between infectious disease specialists and ophthalmologists to ensure adherence to HAART and routine eye examinations.

Abstract
During the first 15 years of the AIDS epidemic patients experienced a high incidence of blindness due to cytomegalovirus (CMV) retinitis and other severe ocular opportunistic infections. Highly active anti-retroviral therapy, introduced in 1996, dramatically decreased the incidence of CMV retinitis. Though CMV retinitis still causes 40% of vision loss in AIDS patients, other conditions such as immune reconstitution uveitis, cataracts, and a significant othercategory -which most investigators believe is directly due to HIV - comprise the majority of cases. HIV causes vascular abnormalities of the conjunctiva and retina in the majority of AIDS patients, as well as retinitis, anterior and posterior uveitis and vasculitis. HIV frequently causes an optic neuropathy and is responsible for the majority of eye movement disorders among HIV patients. Physicians need to be aware that these problems may be the initial manifestation of HIV infections or a sign of highly active anti-retroviral therapy (HAART) failure. Therefore, patients with identifiable risk factors for AIDS who present with ophthalmologic conditions of unknown etiology should be considered for HIV testing. Finally, anti-retroviral therapy has been reported to cause asymptomatic deposits as well as degenerative conditions of both the anterior and posterior segments of the eye.

Abstract
Despite the fact that the majority of eyelid tumors are benign, proper management in daily practice requires detection of the malignant ones. Several clinical criteria are usually proposed to support or reject a hypothesis of malignancy; however, most are of limited reliability. In any case of doubt, outpatient biopsy is recommended, so as to establish the correct diagnosis and formulate the most appropriate treatment plan. In all facial malignancies, the first (and absolutely mandatory) consideration is control of the cancer. Then, restoration of eyelid function can be addressed, in the following order: protection of the globe by complete dynamic eyelid closure and opening, visual function (and prevention of possible deprivation amblyopia) by insuring a clear visual axis, correction of the tear film, efficient lachrymal drainage, and only then the role of the eyelids in facial expression and esthetics. For most malignant eyelid tumors, the best assurance of complete excision is obtained by extemporaneous examination of the resection margins by frozen section (by Mohs' micrographic surgery techniques, or a variation thereof). Currently, advancement and transposition flaps, possibly in combination with tarso-conjunctival or skin grafts, are the most utilised techniques. Despite the lack of histological verification, new treatment modalities, including topical chemotherapy, photodynamic therapy and cryotherapy, may provide interesting treatment options, particularly in collaboration with the dermatologist.

Abstract
An asymptomatic, bluish-gray, movable, raised, and firm left upper eyelid mass had been present for 8 months in an 82-year-old woman. Histopathologic examination revealed a lesion restricted to the dermis and composed in part of a calcific nodule that was circumscribed by an acellular fibrous capsule. An adjacent nodule exhibited proliferating endothelial cells invading a fresh thrombus. Immunohistochemical staining revealed positivity for CD31, CD34, and CD68; D2-40 was negative, ruling out a lymphatic origin. Masson trichrome and elastic staining of deeper sections revealed recanalization of an earlier thrombus; surviving elastic fibers were discovered in the outer wall, establishing a venous source. This is the first reported case of 3 microscopically discernible events (old phlebolith, fresh intravascular endothelial hyperplasia invading a thrombus, and labyrinthine recanalization of a temporally more remote thrombus) in an eyelid varix. The clinical differential diagnosis is reviewed.

Abstract
A 3-year-old girl presented with a hemorrhagic conjunctival lesion in the right eye. The medical history revealed premature cessation of breast feeding, intolerance to the ingestion of baby foods, anorexia, and abdominal distention. Prior to her referral, endoscopic small intestinal biopsy had been carried out under general anesthesia with a possible diagnosis of Celiac Disease (CD). Her parents did not want their child to undergo general anesthesia for the second time for the excisional biopsy. We decided to follow the patient until all systemic investigations were concluded. In evaluation, the case was diagnosed with CD and the conjunctival tumor showed complete regression during gluten-free dietary treatment. The clinical fleshy appearance of the lesion with spider-like vascular extensions and subconjunctival hemorrhagic spots, possible association with an acquired immune system dysfunction due to CD, and spontaneous regression by a gluten-free diet led us to make a presumed diagnosis of conjunctival Kaposi sarcoma.

Abstract
PURPOSE To report 2 cases of severe keratopathy in patients with AIDS with delayed diagnosis of lagophthalmos. METHODS Observational case report. RESULTS The first patient presented with a corneal abscess attributed to old trauma. He responded poorly to topical treatment and suffered corneal penetration. Penetrating keratoplasty was performed, but persistent epithelial defects appeared. Finally, occult lagophthalmos was discovered. Topical ocular lubrication, eye occlusion, and lateral tarsorrhaphy were insufficient, and the graft became conjunctivalized. The second patient had corneal opacity and severe pannus in his right eye and mild punctate keratopathy in his left eye. The left cornea worsened despite treatment with lubricants. In an examination 2 weeks later, we detected a subtle lagophthalmos, which was complicated by upper eyelid retraction in the right eye. A bilateral upper blepharotomy improved the keratopathy. CONCLUSIONS Patients with AIDS with severe weight loss can present with lagophthalmos because of adipose and muscular atrophy in the so-called wasting syndrome. Lagophthalmos in patients with AIDS can be difficult to detect. Clinically significant lagophthalmos is associated with ocular surface lesions in patients with AIDS with wasting syndrome.

Abstract
INTRODUCTION This study was undertaken to document the various ocular manifestations in human immunodeficiency virus (HIV) infected individuals and to correlate such findings with CD4+ T lymphocyte levels in individuals with ocular manifestations. METHODS A total of 150 patients known to be HIV positive referred to a tertiary level army hospital were included in this cross sectional study. All patients underwent complete ophthalmic evaluation. CD4+ count was done only in patients in whom ocular lesions were noted. RESULT Most patients (54.66%) were in the 31-40 years age group. Majority of patients (84.66%) were males. Infection was sexually acquired in 91.33% by heterosexual mode. Majority of cases (34%) examined had presented within 12-18 months of being detected positive for HIV. Ocular involvement was present in 76 (50.66%) cases and the commonest ocular lesion encountered was cytomegalovirus (CMV) retinitis in 23 (30.26%) cases. CD4+ count less than 50 cells/µl was consistently associated with ocular manifestations in 36.84% of HIV positive patients. CONCLUSION This study showed the whole spectrum of ocular lesions in HIV positive cases from CMV retinitis to adnexal lesions. No case of ocular Kaposi's sarcoma was seen in this study.

Abstract
Ocular complications are known to occur as a result of human immunodeficiency virus (HIV) disease. They
can be severe leading to ocular morbidity and visual handicap. Cytomegalovirus (CMV) retinitis is the
commonest ocular opportunistic infection seen in acquired immune deficiency syndrome (AIDS). Though
posterior segment lesions can be more vision-threatening, there are varied anterior segment manifestations
which can also lead to ocular morbidity and more so can affect the quality of life of a HIV-positive person.
Effective antiretroviral therapy and improved prophylaxis and treatment of opportunistic infections have led
to an increase in the survival of an individual afflicted with AIDS. This in turn has led to an increase in the
prevalence of anterior segment and adnexal disorders. Common lesions include relatively benign conditions
such as blepharitis and dry eye, to infections such as herpes zoster ophthalmicus and molluscum contagiosum
and malignancies such as squamous cell carcinoma and Kaposi′s sarcoma. With the advent of highly active
antiretroviral therapy, a new phenomenon known as immune recovery uveitis which presents with increased
inflammation, has been noted to be on the rise. Several drugs used in the management of AIDS such as
nevirapine or indinavir can themselves lead to severe inflammation in the anterior segment and adnexa of the
eye. This article is a comprehensive update of the important anterior segment and adnexal manifestations in
HIV-positive patients with special reference to their prevalence in the Indian population.

Abstract
BACKGROUND How HIV-1 enter into the eyes remains obscure. We postulated that HIV-1 Tat protein can alter the expression of specific tight-junction proteins and disturb the blood retinal barrier, and contributes to HIV trafficking into the eyes. This study is to determine the effects of HIV-1 Tat proteins on the barrier function and tight-junction protein expression of retinal pigment epithelial cell (RPE). METHODS A human RPE cell line (D407) cultured on microporous filter-supports was used. After treating with HIV-1 Tat protein, transepithelial electrical resistance (TER) of confluent RPE cells was measured by epithelial voltmeter. The permeability of the RPE cells to sodium fluorescein was measured. The expressions of the occludin and claudins were determined by real-time polymerase chain reaction, immunofluorescence, and Western blot analysis. Activation of ERK1/2 was detected by Western blot analysis with specific antiphospho protein antibodies. NF-kappaB DNA binding activity was determined by transcription factor assay. Specific pharmacologic inhibitors directed against the MAPKs were used to analyze the signaling involved in barrier destruction of RPE cells exposed to HIV-1 Tat. RESULTS Treating cultured human retinal pigment epithelial cells with 100 nM Tat for 24 hours increased the permeability and decreased the TER of the epithelial monolayer. HIV-1 Tat also disrupted and downregulated the tight-junction proteins claudin-1, claudin-3, and claudin-4 in these cells, whereas claudin-2 was upregulated, and the expression of occludin was unaffected. HIV-1 Tat protein also induced activation of ERK1/2 and NF-kappaB. HIV-1 Tat protein induced barrier destruction, changes in expression of TJs, and activation of ERK1/2 and NF-kappaB were abrogated by inhibitor of ERK1/2 and NF-kappaB. CONCLUSION HIV-1 Tat protein causes increases in the paracellular permeability of RPE cells in vitro concomitant with changes in expression of certain transmembrane proteins associated with the tight junction. The effects of HIV-1 Tat on barrier function of the RPE may be mediated by ERK MAPK and NF-kappaB activation, which may represent potential targets for novel therapeutic approaches for the retinopathy induced by HIV infection.

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