RESUMEN
PURPOSE: To determine the incidence of all-cause and cancer mortality (CM) in association with immunosuppression. DESIGN: Retrospective cohort study at ocular inflammatory disease (OID) subspecialty centers. We harvested exposure and covariate data retrospectively from clinic inception (earliest in 1979) through 2010 inclusive. Then we ascertained overall and cancer-specific mortalities by National Death Index linkage. We constructed separate Cox models to evaluate overall and CM for each class of immunosuppressant and for each individual immunosuppressant compared with person-time unexposed to any immunosuppression. PARTICIPANTS: Patients with noninfectious OID, excluding those with human immunodeficiency infection or preexisting cancer. METHODS: Tumor necrosis factor (TNF) inhibitors (mostly infliximab, adalimumab, and etanercept); antimetabolites (methotrexate, mycophenolate mofetil, azathioprine); calcineurin inhibitors (cyclosporine); and alkylating agents (cyclophosphamide) were given when clinically indicated in this noninterventional cohort study. MAIN OUTCOME MEASURES: Overall mortality and CM. RESULTS: Over 187 151 person-years (median follow-up 10.0 years), during which 15 938 patients were at risk for mortality, we observed 1970 deaths, 435 due to cancer. Both patients unexposed to immunosuppressants (standardized mortality ratio [SMR] = 0.95, 95% confidence interval [CI], 0.90-1.01) and those exposed to immunosuppressants but free of systemic inflammatory diseases (SIDs) (SMR = 1.04, 95% CI, 0.95-1.14) had similar mortality risk to the US population. Comparing patients exposed to TNF inhibitors, antimetabolites, calcineurin inhibitors, and alkylating agents with patients not exposed to any of these, we found that overall mortality (adjusted hazard ratio [aHR] = 0.88, 0.89, 0.90, 1.11) and CM (aHR = 1.25, 0.89, 0.86, 1.23) were not significantly increased. These results were stable in sensitivity analyses whether excluding or including patients with SID, across 0-, 3-, or 5-year lags and across quartiles of immunosuppressant dose and duration. CONCLUSIONS: Our results, in a cohort where the indication for treatment was proven unassociated with mortality risk, found that commonly used immunosuppressants-especially the antimetabolites methotrexate, mycophenolate mofetil, and azathioprine; the TNF inhibitors adalimumab and infliximab, and cyclosporine-were not associated with increased overall and CM over a median cohort follow-up of 10.0 years. These results suggest the safety of these agents with respect to overall and CM for patients treated with immunosuppression for a wide range of inflammatory diseases.

PURPOSE: To estimate the incidence of medication-free remission of chronic anterior uveitis and identify predictors thereof. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients diagnosed with anterior uveitis of longer than 3 months' duration followed up at United States tertiary uveitis care facilities. METHODS: Estimation of remission incidence and identification of associated predictors used survival analysis. MAIN OUTCOME MEASURES: Incidence of medication-free remission. For the primary analysis, remission was defined as inactive uveitis while off treatment at all visits spanning an interval of at least 90 days or-for patients who did not return for follow-up after 90 days-remaining inactive without receiving suppressive medications at all of the last visits. Association of factors potentially predictive of medication-free remission was also studied. RESULTS: Two thousand seven hundred ninety-five eyes of 1634 patients with chronic anterior uveitis were followed up over 7936 eye-years (4676 person-years). The cumulative medication-free, person-year remission incidence within 5 years was 32.7% (95% confidence interval [CI], 30.4%-35.2%). Baseline clinical factors predictive of reduced remission incidence included longer duration of uveitis at presentation (for 2 to 5 years vs. less than 6 months: adjusted hazard ratio [aHR], 0.61; 95% CI, 0.44-0.83), bilateral uveitis (aHR, 0.75; 95% CI, 0.59-0.96), prior cataract surgery (aHR, 0.70; 95% CI 0.56-0.88), and glaucoma surgery (aHR, 0.63; 95% CI, 0.45-0.90). Two time-updated characteristics were also predictive of reduced remission incidence: keratic precipitates (aHR, 0.36; 95% CI, 0.21-0.60) and synechiae (aHR, 0.62; 95% CI, 0.41-0.93). Systemic diagnosis with juvenile idiopathic arthritis and spondyloarthropathy were also associated with reduced remission incidence. Older age at presentation was associated with higher incidence of remission (for age ≥40 years vs. <40 years: aHR, 1.29; 95% CI, 1.02-1.63). CONCLUSIONS: Approximately one third of patients with chronic anterior uveitis remit within 5 years. Longer duration of uveitis, younger age, bilateral uveitis, prior cataract surgery, glaucoma surgery, presence of keratic precipitates and synechiae, and systemic diagnoses of juvenile idiopathic arthritis and spondyloarthropathy predict reduced remission incidence; patients with these factors should be managed taking into account the higher probability of a longer disease course.

PURPOSE: To describe the risk and risk factors for ocular hypertension (OHT) in adults with noninfectious uveitis. DESIGN: Retrospective, multicenter, cohort study. PARTICIPANTS: Patients aged ≥18 years with noninfectious uveitis seen between 1979 and 2007 at 5 tertiary uveitis clinics. METHODS: Demographic, ocular, and treatment data were extracted from medical records of uveitis cases. MAIN OUTCOME MEASURES: Prevalent and incident OHT with intraocular pressures (IOPs) of ≥21 mmHg, ≥30 mmHg, and increase of ≥10 mmHg from documented IOP recordings (or use of treatment for OHT). RESULTS: Among 5270 uveitic eyes of 3308 patients followed for OHT, the mean annual incidence rates for OHT ≥21 mmHg and OHT ≥30 mmHg are 14.4% (95% confidence interval [CI], 13.4-15.5) and 5.1% (95% CI, 4.7-5.6) per year, respectively. Statistically significant risk factors for incident OHT ≥30 mmHg included systemic hypertension (adjusted hazard ratio [aHR], 1.29); worse presenting visual acuity (≤20/200 vs. ≥20/40, aHR, 1.47); pars plana vitrectomy (aHR, 1.87); history of OHT in the other eye: IOP ≥21 mmHg (aHR, 2.68), ≥30 mmHg (aHR, 4.86) and prior/current use of IOP-lowering drops or surgery in the other eye (aHR, 4.17); anterior chamber cells: 1+ (aHR, 1.43) and ≥2+ (aHR, 1.59) vs. none; epiretinal membrane (aHR, 1.25); peripheral anterior synechiae (aHR, 1.81); current use of prednisone >7.5 mg/day (aHR, 1.86); periocular corticosteroids in the last 3 months (aHR, 2.23); current topical corticosteroid use [≥8×/day vs. none] (aHR, 2.58); and prior use of fluocinolone acetonide implants (aHR, 9.75). Bilateral uveitis (aHR, 0.69) and previous hypotony (aHR, 0.43) were associated with statistically significantly lower risk of OHT. CONCLUSIONS: Ocular hypertension is sufficiently common in eyes treated for uveitis that surveillance for OHT is essential at all visits for all cases. Patients with 1 or more of the several risk factors identified are at particularly high risk and must be carefully managed. Modifiable risk factors, such as use of corticosteroids, suggest opportunities to reduce OHT risk within the constraints of the overriding need to control the primary ocular inflammatory disease.

PURPOSE: To evaluate the risk of and risk factors for retinal neovascularization (NV) in cases of uveitis. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients with uveitis at 4 US academic ocular inflammation subspecialty practices. METHODS: Data were ascertained by standardized chart review. Prevalence data analysis used logistic regression. Incidence data analysis used survival analysis with time-updated covariates where appropriate. MAIN OUTCOME MEASURES: Prevalence and incidence of NV. RESULTS: Among uveitic eyes of 8931 patients presenting for initial evaluation, 106 of 13,810 eyes had NV (prevalence = 0.77%, 95% confidence interval [CI], 0.60-0.90). Eighty-eight more eyes developed NV over 26,465 eye-years (incidence, 0.33%/eye-year; 95% CI, 0.27-0.41). Factors associated with incident NV include age <35 years compared with >35 years (adjusted hazard ratio [aHR], 2.4; 95% CI, 1.5-3.9), current cigarette smoking (aHR, 1.9; 95% CI, 1.1-3.4), and systemic lupus erythematosus (aHR, 3.5, 95% CI, 1.1-11). Recent diagnosis of uveitis was associated with an increased incidence of NV (compared with patients diagnosed >5 years ago, aHR, 2.4 [95% CI, 1.1-5.0] and aHR, 2.6 [95% CI, 1.2-6.0] for diagnosis within <1 year vs. 1-5 years, respectively). Compared with anterior uveitis, intermediate uveitis (aHR, 3.1; 95% CI, 1.5-6.6), posterior uveitis (aHR, 5.2; 95% CI, 2.5-11), and panuveitis (aHR, 4.3; 95% CI, 2.0-9.3) were associated with a similar degree of increased NV incidence. Active (aHR, 2.1, 95% CI, 1.2-3.7) and slightly active (aHR, 2.4, 95% CI, 1.3-4.4) inflammation were associated with an increased incidence of NV compared with inactive inflammation. Neovascularization incidence also was increased with retinal vascular occlusions (aHR, 10, 95% CI, 3.0-33), retinal vascular sheathing (aHR, 2.6, 95% CI, 1.4-4.9), and exudative retinal detachment (aHR, 4.1, 95% CI, 1.3-13). Diabetes mellitus was associated with a somewhat increased incidence of retinal NV (aHR, 2.3, 95% CI, 1.1-4.9), and systemic hypertension (aHR 1.5, 95% CI, 0.89-2.4) was associated with nonsignificantly increased NV incidence. Results were similar in sensitivity analyses excluding the small minority of patients with diabetes mellitus. CONCLUSIONS: Retinal NV is a rare complication of uveitis, which occurs more frequently in younger patients, smokers, and those with intermediate/posterior/panuveitis, systemic vasculopathy, retinal vascular disease, or active inflammation. Inflammation and retinal NV likely are linked; additional studies are needed to further elucidate this connection.

PURPOSE: To characterize the risk and risk factors for intraocular pressure (IOP) elevation in pediatric noninfectious uveitis. DESIGN: Multicenter retrospective cohort study. PARTICIPANTS: Nine hundred sixteen children (1593 eyes) younger than 18 years at presentation with noninfectious uveitis followed up between January 1978 and December 2007 at 5 academic uveitis centers in the United States. METHODS: Medical records review by trained, certified experts. MAIN OUTCOME MEASURES: Prevalence and incidence of IOP of 21 mmHg or more and 30 mmHg or more and incidence of a rise in IOP by 10 mmHg or more. To avoid underascertainment, outcomes were counted as present when IOP-lowering therapies were in use. RESULTS: Initially, 251 (15.8%) and 46 eyes (2.9%) had IOP ≥21 mmHg and ≥30 mmHg, respectively. Factors significantly associated with presenting IOP elevation included age of 6 to 12 years (versus other pediatric ages), prior cataract surgery, pars plana vitrectomy, duration of uveitis ≥6 months, contralateral IOP elevation, presenting visual acuity worse than 20/40, and topical corticosteroid use (in a dose-response relationship). The median follow-up was 1.25 years (interquartile range, 0.4-3.66). The estimated incidence of any observed IOP elevation to ≥21 mmHg, to ≥30 mmHg, and increase in IOP by ≥10 mmHg was 33.4%, 14.8%, and 24.4%, respectively, within 2 years. Factors associated with IOP elevation included pars plana vitrectomy, contralateral IOP elevation (adjusted hazard ratio [aHR], up to 9.54; P < 0.001), and the use of topical (aHR, up to 8.77 that followed a dose-response relationship; P < 0.001), periocular (aHR, up to 7.96; P < 0.001), and intraocular (aHR, up to 19.7; P < 0.001) corticosteroids. CONCLUSIONS: Intraocular pressure elevation affects a large minority of children with noninfectious uveitis. Statistically significant risk factors include IOP elevation or use of IOP-lowering treatment in the contralateral eye and local corticosteroid use that demonstrated a dose-and route of administration-dependent relationship. In contrast, use of immunosuppressive drug therapy did not increase such risk. Pediatric eyes with noninfectious uveitis should be followed up closely for IOP elevation, especially when strong risk factors such as the use of local corticosteroids and contralateral IOP elevation are present.

PURPOSE: Among cases of visually significant uveitic macular edema (ME), to estimate the incidence of visual improvement and identify predictive factors. DESIGN: Retrospective cohort study. PARTICIPANTS: Eyes with uveitis, seen at 5 academic ocular inflammation centers in the United States, for which ME was documented to be currently present and the principal cause of reduced visual acuity (<20/40). METHODS: Data were obtained by standardized chart review. MAIN OUTCOME MEASURES: Decrease of ≥ 0.2 base 10 logarithm of visual acuity decimal fraction-equivalent; risk factors for such visual improvement. RESULTS: We identified 1510 eyes (of 1077 patients) with visual impairment to a level <20/40 attributed to ME. Most patients were female (67%) and white (76%), and had bilateral uveitis (82%). The estimated 6-month incidence of ≥ 2 lines of visual acuity improvement in affected eyes was 52% (95% confidence interval [CI], 49%-55%). Vision reduced by ME was more likely to improve by 2 lines in eyes initially with poor visual acuity (≤ 20/200; adjusted hazard ratio [HR] 1.5; 95% CI, 1.3-1.7), active uveitis (HR, 1.3; 95% CI, 1.1-1.5), and anterior uveitis as opposed to intermediate (HR, 1.2), posterior (HR, 1.3), or panuveitis (HR, 1.4; overall P = 0.02). During follow-up, reductions in anterior chamber or vitreous cellular activity or in vitreous haze each led to significant improvements in visual outcome (P <0.001 for each). Conversely, snowbanking (HR, 0.7; 95% CI, 0.4-0.99), posterior synechiae (HR, 0.8; 95% CI, 0.6-0.9), and hypotony (HR, 0.2; 95% CI, 0.06-0.5) each were associated with lower incidence of visual improvement with respect to eyes lacking each of these attributes at a given visit. CONCLUSIONS: These results suggest that many, but not all, patients with ME causing low vision in a tertiary care setting will enjoy meaningful visual recovery in response to treatment. Evidence of significant ocular damage from inflammation (posterior synechiae and hypotony) portends a lower incidence of visual recovery. Better control of anterior chamber or vitreous activity is associated with a greater incidence of visual improvement, supporting an aggressive anti-inflammatory treatment approach for ME cases with active inflammation.

PURPOSE: To identify factors predictive of remission of inflammation in new-onset anterior uveitis cases treated at tertiary uveitis care facilities. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients seeking treatment at participating academic uveitis clinics within 90 days of initial diagnosis of anterior uveitis. METHODS: Retrospective cohort study based on standardized chart review. MAIN OUTCOME MEASURES: Factors predictive of remission (no disease activity without corticosteroid or immunosuppressive treatments at all visits during a 90-day period). RESULTS: Nine hundred ninety eyes (687 patients) had a first-ever diagnosis of anterior uveitis within 90 days before initial presentation and had follow-up visits thereafter. The median follow-up time was 160 days. Systemic diagnoses with juvenile idiopathic arthritis (JIA; adjusted hazard ratio [aHR], 0.38; 95% confidence interval [CI], 0.19-0.74) and Behçet's disease (aHR, 0.10; 95% CI, 0.01-0.85) were associated with a lower incidence of uveitis remission. Cases of bilateral uveitis (aHR, 0.68; 95% CI, 0.54-0.87) and those with a history of cataract surgery before presentation (aHR, 0.51; 95% CI, 0.29-0.87) also had a lower incidence of remission. Regarding clinical findings at the initial visit, a high degree of vitreous cells at initial presentation was associated with a lower incidence of remission (for 1+ or more vs. none: aHR, 0.72; 95% CI, 0.55-0.95). An initial visual acuity of 20/200 or worse, with respect to 20/40 or better, also was predictive of a lower incidence of remission (aHR, 0.52; 95% CI, 0.32-0.86). CONCLUSIONS: Factors associated with a lower incidence of remission among new-onset anterior uveitis cases included diagnosis with JIA, Behçet's disease, bilateral uveitis, history of cataract surgery, findings of 1+ or more vitreous cells at presentation, and an initial visual acuity of 20/200 or worse. Patients with these risk factors seem to be at higher risk of persistent inflammation; reciprocally, patients lacking these factors would be more likely to experience remission. Patients with risk factors for nonremission of uveitis should be managed taking into account the higher probability of a chronic inflammatory course.

PURPOSE: To evaluate the benefits and complications of periocular depot corticosteroid injections in patients with ocular inflammatory disorders. DESIGN: Multicenter, retrospective cohort study. PARTICIPANTS: A total of 914 patients (1192 eyes) who had received ≥ 1 periocular corticosteroid injection at 5 tertiary uveitis clinics in the United States. METHODS: Patients were identified from the Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study. Demographic and clinical characteristics were obtained at every visit via medical record review by trained reviewers. MAIN OUTCOME MEASURES: Control of inflammation, improvement of visual acuity (VA) to ≥ 20/40, improvement of VA loss attributed to macular edema (ME), incident cataract affecting VA, cataract surgery, ocular hypertension, and glaucoma surgery. RESULTS: Among 914 patients (1192 eyes) who received ≥ 1 periocular injection during follow-up, 286 (31.3%) were classified as having anterior uveitis, 303 (33.3%) as intermediate uveitis, and 324 (35.4%) as posterior or panuveitis. Cumulatively by ≤ 6 months, 72.7% (95% CI, 69.1-76.3) of the eyes achieved complete control of inflammation and 49.7% (95% CI, 45.5-54.1) showed an improvement in VA from <20/40 to ≥ 20/40. Among the subset with VA <20/40 attributed to ME, 33.1% (95% CI, 25.2-42.7) improved to ≥ 20/40. By 12 months, the cumulative incidence of ≥ 1 visits with an intraocular pressure of ≥ 24 mmHg and ≥ 30 mmHg was 34.0% (95% CI, 24.8-45.4) and 15.0% (95% CI, 11.8-19.1) respectively; glaucoma surgery was performed in 2.4% of eyes (95% CI, 1.4-3.9). Within 12 months, among phakic eyes initially ≥ 20/40, the incidence of a reduction in VA to <20/40 attributed to cataract was 20.2% (95% CI, 15.9-25.6); cataract surgery was performed within 12 months in 13.8% of the initially phakic eyes (95% CI, 11.1-17.2). CONCLUSIONS: Periocular injections were effective in treating active intraocular inflammation and in improving reduced VA attributed to ME in a majority of patients. The response pattern was similar across anatomic locations of uveitis. Overall, VA improved in one half of the patients at some point within 6 months. However, cataract and ocular hypertension occurred in a substantial minority.

PURPOSE: To evaluate the incidence, remission, and relapse of post-surgical cystoid macular edema (PCME) following cataract surgery in inflammatory eye disease. METHODS: A total of 1859 eyes that had no visually significant macular edema prior to cataract surgery while under tertiary uveitis management were included. Standardized retrospective chart review was used to gather clinical data. Univariable and multivariable logistic regression models with adjustment for inter-eye correlations were performed. RESULTS: PCME causing VA 20/50 or worse was reported in 286 eyes (15%) within 6 months of surgery. Adults age 18-64 years as compared to children (adjusted odds ratio [aOR] = 2.42, for ages 18 to 44 years and aOR = 1.93 for ages 45 to 64 years, overall P = .02); concurrent use of systemic immunosuppression (conventional aOR 1.53 and biologics aOR = 2.68, overall P = .0095); preoperative VA 20/50 or worse (overall P < .0001); cataract surgery performed before 2000 (overall P = .03) and PMCE in fellow eye (aOR = 3.04, P = .0004) were associated with development of PCME within 6 months of cataract surgery. PCME resolution was seen in 81% of eyes at 12 months and 91% of eyes at 24 months. CME relapse was seen in 12% eyes at 12 months and 19% eyes at 24 months. CONCLUSIONS: PCME occurs frequently in uveitic eyes undergoing cataract surgery; however, most resolve within a year. CME recurrences likely are due to the underlying disease process and not relapses of PCME.
RESUMEN
OBJECTIVE: To evaluate the incidence of visually significant posterior capsule opacification (PCO with visual acuity ≤20/50) and the incidence of Nd:YAG laser capsulotomy in the year following cataract surgery for uveitic eyes. METHOD: Patients were identified from the Systemic Immunosuppressive Therapy for Eye Diseases (SITE) Cohort Study using a standardized chart review process. RESULTS: Among 1,855 uveitic eyes of 1,370 patients who had undergone cataract surgery, visually significant PCO occurred in 297 eyes (16%), and YAG laser capsulotomy was done in 407 eyes (22%) within the first year following surgery. Higher odds of developing 20/50 visual acuity attributed to PCO were noted in children and young adults compared with adults older than 65 years of age (overall pâ¯=â¯0.03). Poorer preoperative visual acuity (overall pâ¯=â¯0.0069) and postoperative inflammation (odds ratio [OR]â¯=â¯1.83; 95% CI, 1.37-2.45; p < 0.0001) were associated with PCO incidence. In multivariable analysis, risk factors for YAG laser capsulotomy were younger age groups compared with those older than 65 years of age at the time of surgery (adjusted OR [aOR]â¯=â¯1.90-2.24; 95% CI, 1.90-2.24; overall pâ¯=â¯0.0007), female sex (aORâ¯=â¯1.37; 95% CI, 1.03-1.82; pâ¯=â¯0.03), postoperative active inflammation (aORâ¯=â¯165; 95% CI, 1.27-2.16; overall p < 0.0001), extracapsular cataract extraction compared with phacoemulsification (aORâ¯=â¯1.70; 95% CI, 1.17-2.47; overall p < 0.0001), and insertion of an intraocular lens (aORâ¯=â¯4.60; 95% CI, -2.29-9.25; p < 0.0001). Black race was associated with lower YAG laser capsulotomy incidence than Whites (aORâ¯=â¯0.36; 95% CI, 0.24-0.52; overall p < 0.0001). CONCLUSIONS: Vision-reducing (≤20/50) PCO is common, occurring in about one sixth of uveitic eyes within 1 year of cataract surgery; a higher number (22%) of eyes underwent YAG laser capsulotomy within the first year. Age and postoperative inflammation following cataract surgery are the variables most associated with the incidence of visually significant PCO and YAG laser capsulotomy.
RESUMEN
PURPOSE: To describe the incidence of and risk factors for visual acuity (VA) loss and ocular complications in patients with juvenile idiopathic arthritis (JIA)-associated uveitis. DESIGN: Multicenter retrospective cohort study. PARTICIPANTS: A total of 327 patients (596 affected eyes) with JIA-associated uveitis managed at 5 tertiary uveitis clinics in the United States. METHODS: Participants were identified from the Systemic Immunosuppressive Therapy for Eye Diseases (SITE) cohort study. Demographic and clinical characteristics were obtained for every eye of every patient at every visit via medical record review by trained expert reviewers. MAIN OUTCOME MEASURES: Loss of VA to 20/50 or to 20/200 or worse thresholds and the development of ocular complications. RESULTS: At presentation, 240 eyes (40.3%) had a VA of ≤20/50, 144 eyes (24.2%) had a VA of ≤20/200, and 359 eyes (60.2%) had at least 1 ocular complication. The incidences of VA loss to the ≤20/50 and ≤20/200 thresholds were 0.18 and 0.09 per eye-year (EY), respectively; the incidence of developing at least 1 new ocular complication over follow-up was 0.15/EY (95% confidence interval [CI], 0.13-0.17). However, among eyes with uveitis that had no complications at presentation, the rate of developing at least 1 ocular complication during follow-up was lower (0.04/EY; 95% CI, 0.02-0.06). Posterior synechiae, active uveitis, and prior intraocular surgery were statistically significantly associated with VA to the ≤20/50 and ≤20/200 thresholds both at presentation and during follow-up. Increasing (time-updated) anterior chamber cell grade was associated with increased rates of visual loss in a dose-dependent fashion. Use of immunosuppressive drugs was associated with a reduced risk of visual loss, particularly for the ≤20/50 outcome (hazard ratio, 0.40; 95% CI, 0.21-0.75; P<0.01). CONCLUSIONS: Ocular complications and vision loss were common in our cohort. Increasing uveitis activity was associated with increased risk of vision loss, and use of immunosuppressive drugs was associated with reduced risk of vision loss, suggesting that control of inflammation and use of immunosuppression may be critical aspects in improving the outcomes of patients with JIA-related uveitis.

PURPOSE: To estimate the incidence/risk factors for cataract in noninfectious anterior uveitis. DESIGN: Retrospective multicenter cohort study (6 US tertiary uveitis sites, 1978-2010). METHODS: Data were harvested by trained expert reviewers, using protocol-driven review of experts' charts. We studied cataract incidence-newly reduced visual acuity worse than 20/40 attributed to cataract; or incident cataract surgery-in 3923 eyes of 2567 patients with anterior uveitis. RESULTS: Cataract developed in 507 eyes (54/1000 eye-years, 95% CI 49-59). Time-updated risk factors associated with cataract included older age (≥65 vs <18 years: adjusted hazard ratio [aHR] 5.04, 95% CI 3.04-8.33), higher anterior chamber cell grade (P(trend)=0.001), prior incisional glaucoma surgery (aHR 1.86, 95% CI 1.10-3.14), band keratopathy (aHR 2.23, 95% CI 1.47-3.37), posterior synechiae (aHR 3.71, 95% CI 2.83-4.87), and elevated intraocular pressure ≥30 vs 6-20 mm Hg (aHR 2.57, 95% CI 1.38-4.77). Primary acute (aHR 0.59, 95% CI 0.30-1.15) and recurrent acute (aHR 0.74, 95% CI 0.55-0.98) had lower cataract risk than chronic anterior uveitis. Higher-dose prednisolone acetate 1%-equivalent use (≥2 drops/day) was associated with >2-fold higher cataract risk in eyes with anterior chamber cell grades 0.5+ or lower but was not associated with higher cataract risk in the presence of anterior chamber cells of grade 1+ or higher. CONCLUSIONS: Cataract complicates anterior uveitis in â¼5.4/100 eye-years. Several fixed and modifiable risk factors were identified, yielding a point system to guide cataract risk minimization. Topical corticosteroids only were associated with increased cataract risk when anterior chamber cells were absent or minimally present, suggesting their use to treat active inflammation (which itself is cataractogenic) does not cause a net increase in cataract incidence.

OBJECTIVE: We sought to describe the risk and risk factors for hypotony in a noninfectious uveitis cohort. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients with noninfectious uveitis seen between 1979 and 2007 at 4 academic ocular inflammation specialty clinics. METHODS: Data were collected from medical records by trained, certified, expert reviewers. MAIN OUTCOME MEASURES: Hypotony (<5 mmHg) and low intraocular pressure (<8 mmHg), each sustained for ≥ 2 visits spanning ≥ 30 days. RESULTS: During follow-up, 126 of 6785 patients (1.86%) developed hypotony at the rate of 0.61% (95% confidence interval [CI], 0.50-0.75%) per eye-year. Cataract surgery was associated with a 7.5-fold risk (adjusted hazard ratio [aHR], 7.51; 95% CI, 3.97-14.23) of incident hypotony. Phacoemulsification, the type of cataract surgery associated with the least hypotony risk still was associated with nearly 5-fold higher hypotony incidence (aHR, 4.87; 95% CI, 2.25-10.55). Increased risk was observed in children (aHR, 2.92; 95% CI, 1.20-7.10) with respect to young adults, and duration of uveitis of >5 years (aHR, 3.08; 95% CI, 1.30-7.31) with respect to uveitis of <6 month duration. Band keratopathy, ≥ 3+ vitreous cells, exudative retinal detachment, posterior synechia, and a history of pars plana vitrectomy also were associated with greater hypotony incidence. With respect to anterior uveitis, intermediate uveitis (aHR, 0.17; 95% CI, 0.05-0.56) and posterior uveitis (aHR, 0.11; 95% CI, 0.03-0.45) were associated with lower hypotony risk, whereas panuveitis (aHR, 1.25; 95% CI, 0.67-2.35) was similar. Approximately five-sixths (84.1%) of eyes presenting with hypotony had a visual acuity of ≤ 20/200 (aOR for visual acuity ≤ 20/200, 13.85; 95% CI, 7.23-26.53). Risk factors for prevalent hypotony were similar. CONCLUSIONS: The risk of hypotony is low among eyes with noninfectious uveitis, but is more frequently observed in cases with anterior segment inflammation. Signs of present or past inflammation were associated with greater risk, suggesting excellent inflammatory control may reduce the risk of hypotony. Prior ocular surgery also was associated with higher risk; cataract surgery in particular was associated with much higher risk of hypotony. Lower risk of hypotony with phacoemulsification than with alternative cataract surgery approaches suggests the phacoemulsification approach is preferable.

OBJECTIVE: To identify the incidence and risk factors for corticosteroid-induced hyperglycemia requiring medical therapy among patients with inflammatory eye diseases. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients with ocular inflammation followed at 5 United States tertiary centers that initially were neither diabetic nor taking hypoglycemic medications. METHODS: Eligible patients who used oral corticosteroids during follow-up were identified and followed longitudinally for initiation of hypoglycemic medication over 1 year after beginning corticosteroids. The remaining eligible patients were followed for 1 year after their initial visit. Survival analysis was used to calculate the risk of hyperglycemia requiring medical therapy and to identify potential risk factors. MAIN OUTCOME MEASURES: Initiation of hypoglycemic medications. RESULTS: Among 2073 non-diabetic patients treated with oral corticosteroids, 25 (1.21%) initiated hypoglycemic therapy compared with 5 of 2666 patients (0.19%) not treated with oral corticosteroids (relative risk [RR], 4.39; 95% confidence interval [CI], 1.68-11.5). The RR tended to be higher in association with higher initial doses (for initial doses <40 mg of prednisone per day: RR, 3.23; 95% CI, 1.08-9.64; for initial prednisone dose ≥40 mg/d: RR, 5.51; 95% CI, 2.01-15.1). Other risk factors for the initiation of hypoglycemic therapy included older age (RR [per each additional 10 years], 1.46; 95% CI, 1.15-1.85; P = 0.002) and African-American race (RR, 2.94; 95% CI, 1.34-6.43; P = 0.007). CONCLUSIONS: These results suggest that the absolute risk of corticosteroid-induced hyperglycemia that is detected and treated with hypoglycemic therapy in the tertiary ocular inflammation setting is low (an excess cumulative risk on the order of 1% within 1 year), although on a relative scale it is approximately 4.4-fold higher than in patients not treated with oral corticosteroids. Older age and African-American race also were risk factors. Physicians who use systemic corticosteroids for ocular inflammatory diseases should be aware of this risk, and should consider surveillance for hyperglycemia among high-risk patients. However, given the low absolute risk, routine laboratory monitoring or referral for monitoring may not be necessary for low-risk patients.

PURPOSE: To estimate the incidence of corneal endothelial transplantation (CET) and identify risk factors among patients with noninfectious ocular inflammation. DESIGN: Retrospective cohort study. METHODS: Adult patients attending United States tertiary uveitis care facilities diagnosed with noninfectious ocular inflammation were identified from the Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study. Time-to-event analysis was used to estimate the incidence of CET, including penetrating keratoplasty, Descemet stripping endothelial keratoplasty, or Descemet membrane endothelial keratoplasty procedures. The incidence of CET was calculated. Potential risk factors for CET were also evaluated using Cox regression, accounting for correlation between eyes of the same patient. RESULTS: Overall, 14,264 eyes met eligibility criteria for this analysis, with a median follow-up of 1.8 eye-years. The Kaplan-Meier estimated incidence of CET within 10 years was 1.10% (95% CI, 0.68%-1.53%). Risk factors for CET included age >60 years vs <40 years (adjusted hazard ratio [aHR], 16.5; 95% CI, 4.70-57.9), anterior uveitis and scleritis vs other types (aHR, 2.97; 95% CI, 1.46-6.05; and aHR, 4.14; 95% CI,1.28-13.4, respectively), topical corticosteroid treatment (aHR, 2.84; 95% CI, 1.32-6.13), cataract surgery (aHR, 4.44; 95% CI, 1.73-11.4), tube shunt surgery (aHR, 11.9; 95% CI, 5.30-26.8), band keratopathy (aHR, 5.12; 95% CI, 2.34-11.2), and hypotony (aHR, 7.38; 95% CI, 3.14-17.4). Duration of uveitis, trabeculectomy, peripheral anterior synechia, and ocular hypertension had no significant association after multivariate adjustment. CONCLUSIONS: In patients with ocular inflammation, CET occurred infrequently. Tube shunt surgery, hypotony, band keratopathy, cataract surgery, and anterior segment inflammation were associated with increased risk of undergoing CET; these factors likely are associated with endothelial cell damage.

PURPOSE: To evaluate the risk of and risk factors for a second episode (relapse) among patients with remitted primary anterior uveitis. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients with primary anterior uveitis presenting to 1 of 4 academic ocular inflammation subspecialty practices achieving remission of the primary episode within 90 days of initial uveitis diagnosis. METHODS: Data were obtained by standardized chart review. MAIN OUTCOME MEASURES: Time to relapse of anterior uveitis and risk factors for relapse. RESULTS: We included 102 patients with a first episode of anterior uveitis who were seen within 90 days of first-ever uveitis onset and followed for 165 person-years after achieving remission of the initial episode. Most patients were female (60%) and white (78%). Forty patients had a recurrence of anterior uveitis. The incidence of relapse was 24% per person-year (95% confidence interval [CI], 17%-33%). At 1.5 years after remission, 61% (95% CI, 48%-71%) were still in remission. Younger adults had significantly higher relapse risk than middle-aged adults (hazard ratio [18- to 35-year-old persons vs. 35- to 55-year-old persons], 2.7; 95% CI, 1.3-6.0). CONCLUSIONS: Our results suggest that many patients with remitted primary anterior uveitis presenting for tertiary uveitis care will relapse. Age in the young adult range was associated with higher risk of relapse. Given the high relapse risk, management of patients with primary anterior uveitis should include an explicit plan for detecting and managing relapses.

PURPOSE: To assess how often non-infectious anterior scleritis remits and identify predictive factors. METHODS: Our retrospective cohort study at four ocular inflammation subspecialty centers collected data for each affected eye/patient at every visit from center inception (1978, 1978, 1984, 2005) until 2010. Remission was defined as inactivity of disease off all suppressive medications at all visits spanning at least three consecutive months or at all visits up to the last visit (to avoid censoring patients stopping follow-up after remission). Factors potentially predictive of remission were assessed using Cox regression models. RESULTS: During 1,906 years' aggregate follow-up of 832 affected eyes, remission occurred in 214 (170 of 584 patients). Median time-to-remission of scleritis = 7.8 years (95% confidence interval [CI]: 5.7, 9.5). More remissions occurred earlier than later during follow-up. Factors predictive of less scleritis remission included scleritis bilaterality (adjusted hazard ratio [aHR] = 0.46, 95% CI: 0.32-0.65); and diagnosis with any systemic inflammatory disease (aHR = 0.36, 95% CI: 0.23-0.58), or specifically with Rheumatoid Arthritis (aHR = 0.22), or Granulomatosis with Polyangiitis (aHR = 0.08). Statin treatment (aHR = 1.53, 95% CI: 1.03-2.26) within ≤90 days was associated with more remission incidence. CONCLUSIONS: Our results suggest scleritis remission occurs more slowly in anterior scleritis than in newly diagnosed anterior uveitis or chronic anterior uveitis, suggesting that attempts at tapering suppressive medications is warranted after long intervals of suppression. Remission is less frequently achieved when systemic inflammatory diseases are present. Confirmatory studies of whether adjunctive statin treatment truly can enhance scleritis remission (as suggested here) are needed.

Introduction: We evaluated visual acuity (VA) over 5 years in a subspecialty noninfectious uveitis population.Methods: Retrospective data from 5,530 noninfectious uveitis patients with anterior, intermediate, posterior or panuveitis were abstracted by expert reviewers. Mean VA was calculated using inverse probability of censoring weighting to account for losses to follow-up.Results: Patients were a median of 41 years old, 65% female, and 73% white. Initial mean VA was worse among panuveitis (20/84) than posterior (20/64), intermediate (20/47), and anterior (20/37) uveitides. On average, mean VA improved by 0.62, 0.51, 0.37, and 0.26 logMAR-equivalent lines over 2 years, respectively (each P < .001), then remained stable, except posterior uveitis mean VA worsened to initial levels.Conclusion: Mean VA of uveitic eyes improved and, typically, improvement was sustained under uveitis subspecialty care. Because VA tends to improve under tertiary care, mean VA change appears a better outcome for clinical studies than time-to-loss of VA.

INTRODUCTION: We evaluated the associations of clinical and demographic characteristics with visual acuity (VA) with over 5 years in a subspecialty noninfectious uveitis population. METHODS: Retrospective data from 5,530 noninfectious uveitis patients were abstracted by expert reviewers, and contemporaneous associations of VA with demographic and clinical factors were modeled. RESULTS: Patients were a median of 41 years old, 65% female, and 73% white. Eyes diagnosed ≥5 years prior to cohort entry had worse VA (-1.2 lines) than those diagnosed <6 months prior, and eyes with cataract surgery performed prior to entry had worse VA (-5.9 lines) than those performed during follow-up. Vitreous haze (-4.2 lines for 3+ vs quiet), hypotony (-2.5 lines for ≤5 mm Hg vs 6-23 mm Hg), and CNV (-1.8 lines) all were strongly associated with reduced VA. CONCLUSION: Factors associated with reduced VA included well-known structural complications, and lack of subspecialty care during cataract surgery.

PURPOSE: To determine the incidence of and predictive factors for cataract in intermediate uveitis. DESIGN: Retrospective cohort study. METHODS: Patients were identified from the Systemic Immunosuppressive Therapy for Eye Diseases Cohort Study, in which medical records were reviewed to determine demographic and clinical data of every eye/patient at every visit at 5 participating US tertiary care uveitis centers. The primary outcome was development of vision-compromising cataract as defined by a decrease in visual acuity to 20/40 or less, or requiring cataract surgery. Survival analysis assessed visually defined cataract to avoid bias due to timing of surgery vis-à-vis inflammatory status. RESULTS: Among 2,190 eyes of 1,302 patients with intermediate uveitis, the cumulative incidence of cataract formation was 7.6% by 1 year (95% confidence interval [CI] = 6.2%-9.1%), increasing to 36.6% by 10 years (95% CI = 31.2%-41.6%). Increased cataract risk was observed in eyes with concurrent anterior uveitis causing posterior synechiae (hazard ratio = 2.68, 95% CI = 2.00-3.59, P < .001), and in eyes with epiretinal membrane formation (hazard ratio = 1.54, 95% CI = 1.15-2.07, P = .004). Higher dose corticosteroid therapy was associated with significantly higher incidence of cataract, especially time-updated use of topical corticosteroids ≥2 times/d or ≥4 periocular corticosteroid injections. Low-dose corticosteroid medications (oral prednisone 7.5 mg daily or less, or topical corticosteroid drops <2 times/d) were not associated with increased cataract risk. CONCLUSIONS: Our study found that the incidence of clinically important cataract in intermediate uveitis is moderate. The risk is higher with markers of severity and with higher doses of corticosteroid medications, the latter being potentially modifiable.
