RESUMO
PURPOSE: To report on the value of presence of pigmentation on central anterior lens capsule (PioLe) in HLA B27- associated anterior uveitis (HLA B27-AU). METHODS: 268 patients (320 eyes) with AU were reviewed. Two diagnostic models to predict probability of HLA-B27-AU were developed. The first model included 6 variables (age, gender, unilaterality, presence of non-granulomatous keratic precipitates, hypopyon, and intraocular pressure (IOP). The second model was developed to investigate the added value of PioLe into the first model. RESULTS: Unilaterality, presence of hypopyon, IOP <21 mmHg and PioLe were characteristic for HLA-B27 positive patients (P≤0.003 for all). All of 6 variables had area under receiver operating characteristic curves (AuROC) ≤ 60, but PioLe reached even higher value (65.5). Diagnostic model I and II had AuROC 76.3% (95%CI, 68.4%-84.2%) and 80.0% (95%CI, 72.6%-87.5%), respectively. CONCLUSIONS: Unilaterality, hypopyon, IOP <21 mmHg and presence of PioLe are clinical signs suggesting HLA B27- AU.

PURPOSE: To evaluate the long-term visual outcomes of patients with uveitis undergoing cataract surgery and to identify possible factors influencing the visual prognosis and the development of postoperative complications. METHODS: Retrospective study of all patients with uveitis who underwent cataract surgery between January 2015 and February 2020 in our tertiary referral center. RESULTS: A total of 78 eyes from 78 patients were included in the study. The best-corrected visual acuity (BCVA) improved in 86% of patients, and a BCVA of 0.5 or better was achieved in 57 (73%) patients. A significant correlation was shown between the preoperative and postoperative BCVA (Spearman r = 0.521, p < 0.01). Final BCVA differed between diverse anatomical uveitis entities (p = 0.047), and anterior uveitis demonstrated the best outcomes. Chronic uveitis resulted in a worse final BCVA than acute recurrent uveitis (p = 0.001). The presence of CME any time before the surgery and intermediate uveitis were associated with worse visual prognosis, while systemic therapy for uveitis before surgery and iris manipulation during surgery were not related to visual outcomes. Postoperative development of cystoid macular edema (CME) was closely associated with preexisting CME (p < 0.001) and intermediate uveitis (p = 0.01). CONCLUSIONS: Visual results of cataract surgery in patients with uveitis were beneficial, but limited visual outcomes were more frequently observed in patients with chronic uveitis and intermediate uveitis with a history of CME. In consequence, prevention, or adequate treatment of CME, especially in patients with intermediate uveitis, might result in better visual results of their cataract surgery.

Purpose: Scleritis is a severe inflammatory ocular disorder with unknown pathogenesis. We investigated healthy sclera as well as sclera affected by noninfectious scleritis for differentially expressed proteins using a mass spectrometry approach. Methods: We collected scleral samples of enucleated eyes due to severe noninfectious scleritis (n = 3), and control scleral tissues (n = 5), all exenterated eyes for eyelid carcinomas (n = 4), or choroidal melanoma (n = 1) without scleral invasion. Samples were prepared for the nano liquid-chromatography mass spectrometer (LC-MS), data were analyzed using proteomics software (Scaffold), and is available via ProteomeXchange (identifier PXD038727). Samples were also stained for immuno-histopathological evaluation. Results: Mass spectrometry identified 629 proteins within the healthy and diseased scleral tissues, whereof collagen type XII, VI, and I were the most abundantly expressed protein. Collagen type II-XII was also present. Filaggrin-2, a protein that plays a crucial role in epidermal barrier function, was found upregulated in all scleritis cases. In addition, other epithelial associated proteins were upregulated (such as keratin 33b, 34, and 85, epiplakin, transglutaminase-3, galectin 7, and caspase-14) in scleritis. Further, upregulated proteins involved in regulation of the cytoskeleton (vinculin and myosin 9), and housekeeping proteins were found (elongation factor-2 and cytoplasmic dynein 1) in our study. Upregulation of filaggrin-2 and myosin-9 was confirmed with immunohistochemistry, the latter protein showing co-localization with the endothelial cell marker ETC-related gene (ERG), indicating neovascularization in scleral tissue affected by scleritis. Conclusions: We found upregulation of filaggrin-2 and signs of neovascularization in scleral tissue of patients with noninfectious scleritis. Further research, ideally including more scleritis cases, is needed to validate our findings.

Objectives: To evaluate the associations between anatomical changes and visual outcomes in patients with idiopathic epiretinal membrane (ERM). Materials and Methods: We performed a prospective study of 130 consecutive idiopathic ERM patients and report their visual outcomes and the factors associated with visual outcome and anatomical changes. Results: Of 130 eyes of 130 patients, 87 eyes underwent surgery, while the remaining 43 eyes were observed. At 6-month follow-up, the best-corrected visual acuity (BCVA) increased in the whole population. Mean Early Treatment Diabetic Retinopathy Study letter score changed from 51 to 65 in the surgical group and from 67 to 68 in the non-surgical group. The surgical group had improvement in BCVA at all ERM stages and grades of disorganization of the retinal inner layers (DRIL) (p<0.01). In multivariable analysis of the surgical group, factors associated with BCVA of ETDRS 60 letters or more were no or mild DRIL and the absence of ellipsoid zone disruption at baseline (p=0.002 and p=0.034, respectively) and this statistically significant positive correlation was still maintained at 12-month follow-up. Conclusion: Baseline DRIL grade and presence of ellipsoid zone disruption were the most informative prognostic factors in patients with idiopathic ERMs. Patients with severe DRIL and/or advanced ERMs had improved vision after ERM removal.

OBJECTIVE: To identify the clinical characteristics and prevalence of neoplastic and nonneoplastic inflammatory masquerade syndromes (IMSs) in a tertiary center and determine the useful diagnostic tests. METHODS: A retrospective cohort study of consecutive 1906 patients diagnosed with intraocular inflammatory disease. RESULTS: Of all patients initially diagnosed with intraocular inflammatory disease, we identified 116 (6%) patients with noninflammatory causes (neoplastic IMSs in 36/116; 31% and nonneoplastic IMSs in 52/116; 45%). In addition, 26 patients (22%, 1.4% of all) had drug-induced uveitis and 2 (2%, 0.1% of all) had paraneoplastic uveitis. The large B-cell lymphoma was the most common neoplastic IMS (78%), and the major clinical features were presence of cells and floaters in the vitreous (69%) and chorioretinal lesions (33%). The causes of nonneoplastic IMSs included retinal vascular disorders (38%), hereditary retinal diseases (31%), and degenerative ocular disorders (19%). The common clinical manifestations consisted of chorioretinal scars (27%), small white-yellow retinal lesions (17%), and leaking vessels on fluorescein angiography (14%). CONCLUSION: Noninflammatory causes were determined in 6% of a large population with initial diagnosis of intraocular inflammatory disease. Although neoplastic IMS was commonly characterized by vitreous cells and opacities, most common definitive diagnoses in nonneoplastic IMS encompassed diverse retinal disorders.

Purpose: To detect circulating retina-specific autoreactive CD4+ T-cells and antiretinal antibodies (ARA) in latent tuberculosis (TB)-associated uveitis or sarcoid uveitis patients.Methods: The presence of crude retinal extract (RE) autoreactive CD4+ T-cells was determined by a highly sensitive flowcytometric-based technique examining co-expression of CD25 and CD134 (OX40) on RE stimulated PBMC. The presence of ARA in available matched serum samples was assessed by indirect immunofluorescence.Results: No autoreactive CD4+ T-cells against RE could be detected in either latent TB-associated uveitis or sarcoid uveitis patients, while ARA were detected in the serum of the majority (5/6) of latent TB-associated uveitis and all (3/3) sarcoid uveitis patients.Conclusion: Even with the use of this highly sensitive flowcytometric technique circulating retina-specific autoreactive CD4+ T-cells could not be detected. In contrast, ARA were detected in the majority of patients indicating an adaptive humoral immune response toward retinal antigens had occurred.

Purpose: To report on ocular Vogt-Koyanagi-Harada (VKH)-like syndrome under vemurafenib treatment for metastatic melanoma.Design: A case report.Method: Description of clinical and imaging manifestations including fundus photography, fluorescein, and indocyanine green angiography.Results: A 46-year-old Thai female was diagnosed with metastatic melanoma of the skin and had been treated with multiple surgical excisions, radiotherapy, and vemurafenib (initial dose 480 mg orally twice daily, subsequently increased to maximum dose of 960 mg twice daily). After 6 months of vemurafenib use, she complained of bilateral redness and photophobia and was diagnosed with bilateral anterior uveitis, which was topically treated. Two weeks later, her visual acuity (VA) sharply deteriorated to 20/80 and counting fingers. Ocular examination at that stage stronly resembled acute VKH disease. She exhibited intraocular inflammation, and her fundus examination revealed bilateral optic disc swelling and serous retinal detachment. Fluorescein angiogram showed disc leakage and multiple pinpoint hyperfluorescence leakage spots and indocyanine green demonstrated multiple hypofluorescent spots. Oral prednisolone 30 mg/day was commenced while vemurafenib medication was ceased. Three weeks later, her vision improved, and serous retinal detachment subsided. However, her cutaneous melanoma recurred.Conclusions: Vemurafenib, a potential adjunct treatment for metastatic melanoma, was complicated by the development of panuveitis, papillitis, and multiple serous detachments. These ocular symptoms were similar to the presentation of acute VKH syndrome.

PURPOSE: To determine the prevalence of viral infections in patients with hypertensive anterior uveitis in Thailand from polymerase chain reaction (PCR) of aqueous humor. METHODS: Thirty-one patients with anterior uveitis with intraocular pressure (IOP) above 25 mmHg were included for PCR analysis for cytomegalovirus (CMV), herpes simplex (HSV), varicella-zoster (VZV), rubella, chikungunya and Zika virus. RESULTS: The prevalence of PCR-positive results was 32%, including 19% for CMV, 10% for HSV, and 3% for VZV; PCR for other tested viruses demonstrated negative results. PCR-positive patients exhibited satisfactory IOP control with antiviral and anti-glaucomatous treatment compared to PCR-negative patients, and more than half of PCR-negative patients required glaucoma surgery within 12 months (P = .01). CONCLUSION: PCR evidence of infection with herpes group viruses was found in one-third of patients with hypertensive anterior uveitis; CMV being the most common pathogen. The PCR-positive group generally responded well to a combination of antiviral and anti-glaucoma treatment.

PURPOSE: To assess the clinical and laboratory manifestations and vaccination status of uveitis patients positive for rubella virus (RV) in aqueous humor and investigate its relationship to Fuchs uveitis syndrome (FUS). METHODS: Retrospective study of all uveitis patients, positive for RV in aqueous humor analysis (polymerase chain reaction [PCR] and/or Goldmann-Witmer coefficient [GWC]) between January 2010 and October 2016 at the ophthalmology departments in the Erasmus Medical Center (Rotterdam) and University Medical Center Utrecht. Outcomes of aqueous analyses of FUS patients during this period were assessed. RESULTS: We included 127 patients (144 eyes) positive for RV in aqueous fluid: 23 (20%) by PCR, 120 (97%) by GWC, and 16 (13%) by both. The average age at first presentation was 37 years. Patients typically complained of blurred vision and exhibited a combination of unilateral anterior uveitis, keratic precipitates, vitritis, and absence of posterior synechiae, but the classical FUS was observed in a minority. The main cause of untreatable visual loss was glaucoma. Cystoid macular edema (CME) before intraocular surgery was not encountered. None of the unilateral cases developed involvement of the other eye. None of the patients was vaccinated against RV. All FUS patients, except 2 (5%), were positive for RV. CONCLUSION: RV-associated uveitis and FUS are not exchangeable. Chronic anterior uveitis, vitritis, early development of cataract, and the absence of posterior synechiae and CME characterize RV-associated uveitis. Almost all FUS cases had documented intraocular RV infection, but only some of the patients with RV-associated uveitis presented with FUS.

PURPOSE: Primary vitreoretinal lymphoma [(P)VRL]) is a rare malignancy of the eye localized in the retina, vitreous or choroid. Here, we aim to determine the value of the combination of innovative diagnostic methods for accurate differentiation between (P)VRL and non-(P)VRL in patients with suspect uveitis or vitritis. METHODS: Multicolour flow cytometric immunophenotyping of cells in the vitreous samples was performed using the EuroFlow small sample tube. Additionally, cytokines/chemokines and growth factors were measured in the vitreous specimens using a multiplex immunoassay. Data were evaluated in predefined clinical subgroups using omniviz unsupervised Pearson's correlation visualization and unsupervised heatmap analysis. RESULTS: A total of 53 patients were prospectively included in the period 2012-2015. In the (P)VRL subgroup (n = 10), nine cases showed aberrant surface membrane immunoglobulin (SmIg) light chain expression. In the non-(P)VRL group (n = 43) clearly skewed SmIg light chain expression was observed in two multiple sclerosis-related uveitis cases, but not in other uveitis types. Soluble mediator measurement revealed high interleukin (IL)-10/IL-6 ratios, and high IL-1RA levels in 9/10 (P)VRL cases, but not in any non-(P)VRL case. Further correlation and heatmap analysis revealed a minimal signature of cellular parameters (CD19+ B cells, aberrant SmIg light chain expression) and cytokine parameters (IL-10/IL-6 ratio >1, high IL-10, high IL-1 RA, high monocyte chemotactic protein-1, high macrophage inflammatory protein-1ß) to reliably distinguish (P)VRL from non-(P)VRL. CONCLUSION: Here, we show the power of a combined cellular and proteomics strategy for detecting (P)VRL in vitreous specimens, especially in cases with minor cellular (P)VRL infiltrates.

PURPOSE: To assess the efficacy of glaucoma drainage devices (GDD) in uveitic glaucoma and non-uveitic glaucoma, and to perform a meta-analysis of previously published results to compare with our data. METHODS: Retrospective case-control study, in which all eyes that underwent GDD surgery were included from 2015 onwards. Cases were defined as patients with uveitic glaucoma. Patients with non-uveitic glaucoma served as controls. To compare our results, a review of the literature was performed using PubMed database. RESULTS: A total of 99 eyes were included (38 with uveitic glaucoma). The preoperative IOP was 25.9 ± 7.7 mmHg and 27.9 ± 9.6 mmHg for patients with and without uveitis (p = 0.277). No significant differences were found between patients with and without uveitis in the final IOP or reduction in IOP (44.9% vs. 42.8%, respectively). Within the first year after surgery, 13.2% of cases developed macular edema (vs. 6.6%; p = 0.267) and 15.8% a transient hypotony (vs. 8.2%; p = 0.242). A meta-analysis of 24 studies showed a postoperative weighted mean difference of - 17.8 mmHg and 2.2 lower number of IOP-lowering medications in uveitic glaucoma (compared to - 13.2 mmHg and 3.5 in the current study, respectively). CONCLUSION: GDD surgery in patients with uveitis has a similar effect on IOP as in patients without uveitis. The risks of developing macular edema and hypotony were slightly higher in patients with uveitis, but the results were not statistically significant. These findings are in line with previous reports, though data on the efficacy of GDD surgery and macular edema in uveitic glaucoma is scarce.

BACKGROUND/AIMS: The diagnostic properties of conventional diagnostic tests (ACE and chest radiography) for sarcoidosis-associated uveitis are not ideal. The diagnostic value of lymphopaenia for sarcoidosis-associated uveitis is investigated. METHODS: A retrospective study of 191 consecutive patients with a first uveitis episode visiting the ophthalmology department (Erasmus Medical Center, Rotterdam, The Netherlands). Receiver operating characteristics (ROC) analysis was performed and compared with known ROC values from literature of conventional diagnostic tests for sarcoidosis-associated uveitis. An ideal cut-off was determined for lymphopaenia by calculation of the highest Youden index. RESULTS: Out of all patients with first uveitis attack, 32/191 or 17% were subsequently diagnosed with biopsy-proven or radiological diagnosis of sarcoidosis. Lymphopaenia (<1.5×109/L) was significantly more often observed in patients with sarcoidosis-associated uveitis compared with patients with non-sarcoidosis-associated uveitis (p<0.05). The sensitivity and specificity of lymphopaenia was 75 % and 77 %, respectively. The optimal cut-off for lymphopaenia for diagnosing sarcoidosis-associated uveitis was 1.47 ×109/L. Lymphopaenia resulted in a 12.0 (95% CI 4.7 to 30.5 fold risk for having sarcoidosis, corrected for sex, race and age at onset of uveitis in patients with a first uveitis attack. CONCLUSION: Lymphopaenia is a non-invasive and useful marker for diagnosing sarcoidosis-associated uveitis.

PURPOSE: To analyse intraocular cytokine levels and prevalence of intraocular antiretinal antibodies (ARAs) in patients with retinitis pigmentosa (RP), age-related macular degeneration (AMD), glaucoma and cataract, and correlate the results to clinical manifestations. METHODS: We collected intraocular fluid samples from patients with RP (n = 25), AMD (n = 12), glaucoma (n = 28) and cataract (n = 22), and serum samples paired with the intraocular fluids from patients with RP (N = 7) and cataract (n = 10). Interleukin (IL)-1ß, IL-1ra, IL-2, IL-6, IL-6rα, IL-7, IL-8, IL-10, IL-17A, IL-23, thymus- and activation-regulated chemokine (TARC), monocyte chemoattractant protein-1 (MCP-1), tumour necrosis factor-alpha (TNF-α), placental growth factor (PlGF) and vascular endothelial growth factor (VEGF) were measured using a multiplex assay. Antiretinal antibodies (ARA) detection was performed by indirect immunofluorescence. RESULTS: Increasing age was associated with increasing levels of IL-6, IL-8, TNF-α and VEGF. All patient groups exhibited distinct profiles of intraocular cytokines. Intraocular levels of IL-8 were highest in patients with AMD and glaucoma. Cataract patients exhibited high intraocular levels of IL-23. Intraocular levels of IL-2, IL-6, MCP-1 and PlGF in RP patients exceeded the levels of serum, indicating intraocular production. Intraocular ARAs were found in only one patient with AMD. CONCLUSION: Increased levels of inflammatory cytokines in intraocular fluid of patients with originally noninflammatory ocular diseases show that intraocular inflammation is involved in their pathogenesis of these entities. Moreover, we show that increasing age is associated with increasing levels of intraocular cytokines and conclude that future studies on intraocular mediators should be corrected for age of patients.

PURPOSE: The advances in medicine have led to an increased number of people living with some form of immunodeficiency. Most ocular infections in immunocompromised patients may lead to irreversible blindness. We identify the causes of uveitis in immunocompetent and immunocompromised patients. METHODS: A retrospective cohort study of 1354 consecutive patients. All patients underwent a standard work-up for uveitis. RESULTS: An immunocompromised state was identified in 171/1354 patients (13%), of whom 40 had Human immunodeficiency virus (HIV) infection, 52 received immunosuppressive medications, 28 had concurrent malignant disorder and 20 had other causes for their immunosuppression. In addition, 93/1354 patients (7%) had diabetes mellitus (DM). The prevalence of intraocular infections was much higher in immunocompromised patients than in immunocompetent patients and DM (p < 0.001). Causes of uveitis differed between the diverse immunocompromised groups. The non-HIV immunocompromised patients showed primarily intraocular herpes simplex and varicella zoster virus infections, whilst HIV-positive patients exhibited frequently cytomegalovirus (CMV) retinitis and syphilis. Patients with generalized malignancies were characterized by a lower prevalence of infections and higher prevalence of sarcoidosis. Patients with DM typically showed sarcoidosis and bacterial intraocular infections. The percentage of undetermined uveitis diagnoses was markedly lower in immunosuppressed patients (p < 0.001). CONCLUSION: In immunocompromised patients with uveitis, infections were diagnosed in 46% of cases in contrast to 12% in the immunocompetent patients. The causes of uveitis differed among the various types of immunosuppression. Immunocompromised patients with uveitis require a rapid assessment for the most expected infections.

PURPOSE: Recent insights into the pathogenesis of immune-mediated diseases proposed a new classification, which includes autoimmune and auto-inflammatory diseases. The prevalence of specific autoimmune and auto-inflammatory diseases in uveitis and/or scleritis is not yet known. In this study, we examine the presence of systemic immune-mediated diseases in patients with uveitis and/or scleritis and put a special emphasis on autoimmune disorders by reporting on their clinical manifestations and visual prognosis. METHODS: In this retrospective study, we reviewed data of 1327 patients presenting with uveitis and/or scleritis between January 2010 and July 2016 at the Erasmus Medical Center, Rotterdam, the Netherlands. All patients with noninfectious uveitis and/or scleritis were classified according to novel criteria for immune-mediated diseases. Various clinical data, including visual acuity (VA), of patients with uveitis of autoimmune origin were registered during 5-year follow-up. RESULTS: The origin of uveitis was in 5% (62/1327) autoimmune, in 15% (197/1327) auto-inflammatory and in 14% (180/1327) mixed autoimmune/auto-inflammatory. Patients with classical autoimmune connective tissue disease (N = 17) suffered mostly from rheumatoid arthritis and granulomatosis with polyangiitis and exhibited predominantly scleritis (53%). After 5 years of follow-up, none of the eyes of these patients developed legal blindness (VA of <0.1). The VA in patients with uveitis associated with autoimmune neuro-ophthalmological diseases (multiple sclerosis and neuromyelitis optica; N = 27) remained stable over time. CONCLUSION: Uveitis and scleritis of autoimmune origin were observed in 5% of the total series. The term autoimmune uveitis should not be used as a synonym for intraocular inflammation of noninfectious origin.

PURPOSE: To describe causes, visual outcomes, and prognostic factors in patients with submacular hemorrhage (SMH). DESIGN: Retrospective case review. METHODS: We performed a retrospective review of SMH with a size of at least 1 disc diameter. SMH causes were classified into 3 groups: 1) neovascular age-related macular degeneration (nAMD), 2) polypoidal choroidal vasculopathy (PCV), and 3) other miscellaneous causes. RESULTS: Ninety-eight eyes of 98 patients were included. Based on clinical presentation and indocyanine green angiography (ICGA), the diagnoses of PCV (59%), nAMD (31%), and miscellaneous other causes (10%) were made. PCV patients were younger (P = 0.005) and had larger SMH size than nAMD patients (P = 0.008). Poor visual outcome [>1.0 logarithm of the minimum angle of resolution (logMAR)] at 6 months was associated with low initial visual acuity (VA; >1.0 logMAR; P = 0.002) and with the diagnosis of nAMD (P = 0.02). In addition, limited visual outcomes were noted for patients older than 65 years and those with persistent SMH for at least 2 months. CONCLUSIONS: PCV was the most common cause of SMH in Thailand. ICGA represented a valuable tool for the diagnosis. Visual outcomes were limited for patients with nAMD and for patients who presented with poor initial VA.

RATIONALE: Although chest radiography is currently recommended for the initial evaluation of patients with new-onset uveitis, the efficacy of this diagnostic screening modality is not known. OBJECTIVES: To evaluate the diagnostic value of chest radiographs in patients with active uveitis of recent onset in a tertiary center in Western Europe. METHODS: A retrospective cross-sectional study was conducted by reviewing all chest imaging for adults with new-onset (<1 yr) uveitis of unknown origin undergoing initial evaluation in the Department of Ophthalmology at Erasmus University Medical Center (Rotterdam, the Netherlands). Radiographic findings were related to clinical and other imaging characteristics and to final diagnoses. RESULTS: Screening chest radiographs were abnormal for 30 of 200 patients (15%) included in this study. Twenty-two of the 200 patients (11%) had biopsy-confirmed sarcoidosis, and an additional 12 patients were presumed to have sarcoidosis. The finding of chest radiographic abnormalities interpreted as typical of sarcoidosis was specific (91%; 95% confidence interval, 85.9-94.4%) but not sensitive (64%; 95% confidence interval, 43.0-80.3%) for biopsy-confirmed sarcoidosis. The combination of elevated serum angiotensin-converting enzyme level and chest radiographic findings typical of sarcoidosis increased the sensitivity to 79%. Biopsy-confirmed sarcoidosis was more common in patients with panuveitis (17 of 84; 20%) compared to patients with other anatomical locations of uveitis (5 of 116, 4%; P < 0.001). One patient was diagnosed with active pulmonary and ocular tuberculosis. CONCLUSIONS: Abnormal chest radiographs were found in 15% of patients with active uveitis of unknown origin and onset within 1 year of referral to a tertiary center in the Netherlands. A majority of the abnormal chest radiographs showed findings compatible with a diagnosis of sarcoidosis.

OBJECTIVE: The aim of this study was to report on the prevalence of uveitic secondary glaucoma (USG) and ocular hypertension in patients with uveitis in Thailand, and to identify factors associated with the development of USG and its visual outcome. DESIGN: This is a retrospective cohort study. METHODS: We included 174 consecutive uveitis patients (237 affected eyes) visiting the Ophthalmology Department of Chiang Mai University Hospital, Thailand, from January 2013 to March 2013. RESULTS: The prevalence of USG was 29% (51/174) and that of ocular hypertension was 18% (32/174). The follow-up period ranged from 3 to 96 months (mean±SD=33±21 mo). Characteristics associated with the development of USG were as follows: age at onset of uveitis above 60 years and longer duration of uveitis (P=0.001). No association between location of uveitis and development of USG was observed. Clinical entities associated with the highest prevalence of USG consisted of Posner-Schlossman syndrome and herpetic uveitis. Within the anterior uveitis group, viral etiology was strongly associated with the development of USG, whereas human leukocyte antigen-B27 (HLA-B27)-associated anterior uveitis had lower prevalence of USG than did their HLA-B27-negative counterparts. The prevalence of patients with at least 1 blind eye was significantly higher in those who developed USG (21/51; 41%) than in uveitis patients without glaucoma (22/123; 18%, P=0.001). Characteristics associated with visual loss in USG included poor visual acuity at presentation (P<0.001), and undergoing glaucoma surgery (P<0.05). CONCLUSIONS: The prevalence of secondary glaucoma among Southeast Asian patients with uveitis was 29%. Blindness in at least 1 eye developed more commonly in patients with USG than in uveitis patients without USG.

PURPOSE: Although multiple serum antiretinal autoantibodies (ARAs) have been reported in patients with paraneoplastic and non-paraneoplastic autoimmune retinopathy ((n)pAIR), not all retinal antigens involved in (n)pAIR are specified. This study aims to serologically identify patients with presumed (n)pAIR through determination of both known and unknown ARAs by autoantibody profiling. METHODS: An antigen suspension bead array using 188 different antigens representing 97 ocular proteins was performed to detect ARAs in serum samples of patients with presumed (n)pAIR (n = 24), uveitis (n = 151) and cataract (n = 21). Logistic regressions were used to estimate the associations between ocular antigens and diagnosis. Validation of interphotoreceptor matrix proteoglycan 2 (IMPG2) and recoverin antigens was performed by immunohistochemistry and immunoblot, respectively. RESULTS: Samples of patients with presumed (n)pAIR exhibited a broad spectrum of ARAs. We identified retinal antigens that have already been described previously (e.g. recoverin), but also identified novel ARA targets. Most ARAs were not specific for (n)pAIR since their presence was also observed in patients with cataract or uveitis. High titers of autoantibodies directed against photoreceptor-specific nuclear receptor and retinol-binding protein 3 were more common in patients with presumed (n)pAIR compared to uveitis (p = 0.015 and p = 0.018, respectively). The presence of all other ARAs did not significantly differ between groups. In patients with presumed (n)pAIR, anti-recoverin autoantibodies were the most prevalent ARAs. Validation of bead array results by immunohistochemistry (anti-IMPG2) and immunoblot (anti-recoverin) showed concordant results in (n)pAIR patients. CONCLUSIONS: Patients with (n)pAIR are characterized by the presence of a broad spectrum of ARAs. The diagnosis of (n)pAIR cannot be based on the mere presence of serum ARAs, as these are also commonly present in uveitis as well as in age-related cataract patients.
