RESUMEN

PURPOSE: To evaluate the effectiveness of 3 different intravitreal treatments for persistent or recurrent uveitic macular edema (ME): dexamethasone implant, methotrexate, and ranibizumab. DESIGN: Single-masked, randomized controlled clinical trial. PARTICIPANTS: Patients with minimally active or inactive uveitis and persistent or recurrent uveitic ME in one or both eyes. METHODS: Patients at 33 centers were randomized 1:1:1 to receive 1 of the 3 therapies. Patients with bilateral ME received the same treatment in both eyes. MAIN OUTCOME MEASURES: The primary outcome, measured at 12 weeks, was reduction in central subfield thickness (CST) expressed as a proportion of baseline (CST per CST at baseline) assessed with spectral-domain OCT by readers masked to treatment assignment. Secondary outcomes included improvement and resolution of ME, change in best-corrected visual acuity (BCVA), and elevations in intraocular pressure (IOP). RESULTS: One hundred ninety-four participants (225 eligible eyes) were randomized to dexamethasone (n = 65 participants and 77 eyes), methotrexate (n = 65 participants and 79 eyes), or ranibizumab (n = 64 participants and 69 eyes). All received at least 1 injection of the assigned treatment. At the 12-week primary outcome point, each group showed significant reductions in CST relative to baseline: 35%, 11%, and 22% for dexamethasone, methotrexate, and ranibizumab, respectively. Reduction of ME was significantly greater in the dexamethasone group than for either methotrexate (P < 0.01) or ranibizumab (P = 0.018). Only the dexamethasone group showed a statistically significant improvement in BCVA during follow-up (4.86 letters; P < 0.001). Elevations of IOP by 10 mmHg, to 24 mmHg or more, or both were more common in the dexamethasone group; IOP spikes to 30 mmHg or more were uncommon overall and were not significantly different among groups. Reductions in BCVA of 15 letters or more were more common in the methotrexate group and typically were attributable to persistent ME. CONCLUSIONS: At 12 weeks, in eyes with minimally active or inactive uveitis, dexamethasone was significantly better at treating persistent or recurrent ME than methotrexate or ranibizumab. Risk of IOP elevation was greater with dexamethasone, but elevations to levels of 30 mmHg or more were infrequent.

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.

RESUMEN

During the coronavirus disease 2019 (COVID-19) pandemic, bioethical analyses often emphasized population health and societal benefit. Hospital policies frequently focused on reducing risk of transmitting SARS-CoV-2 by restricting visitors; requiring protective equipment; and screening staff, patients and visitors. While restrictions can be burdensome, they are often justified as essential measures to protect the whole population against a virus with high rates of transmission, morbidity and mortality. Yet communities are not monolithic, and the impacts of these restrictions affect different groups differently. An ophthalmological unit outreach program in Ethiopia serves to illustrate. Pre-operative screening policies were designed to protect as many patients as possible but had adverse impacts on underserved communities. As this case study demonstrates, creating hospital policies that truly serve the good of the society may require a more holistic review of impacts on inequitably positioned communities.

RESUMEN

PURPOSE: To evaluate the long-term outcomes of uveitic macular edema (ME). DESIGN: Longitudinal follow-up of a cohort of participants in a randomized clinical trial. PARTICIPANTS: A total of 248 eyes of 177 participants with uveitic ME enrolled in the Multicenter Uveitis Steroid Treatment (MUST) Trial and Follow-up Study. METHODS: OCT measurements, taken at baseline and annually, were graded by reading center graders masked to clinical data. Macular edema was defined as a center macular thickness (CMT) ≥240 µm on time-domain OCT or time-domain OCT equivalent. Resolution of ME was defined as normalization of macular thickness on OCT. Relapse of ME was defined as increase in macular thickness to ≥240 µm in an eye that previously had resolution. Visual acuity was measured at each visit with logarithmic visual acuity charts. MAIN OUTCOME MEASURES: Resolution and relapse of ME. Visual acuity. RESULTS: Among 227 eyes with ME followed ≥1 year, the cumulative percent of eyes with ME resolving at any point during 7 years was 94% (95% confidence interval [CI], 89-97). Epiretinal membranes on OCT were associated with a lower likelihood of ME resolution (hazard ratio [HR], 0.74; 95% CI, 0.55-1.01; P = 0.05). Among 177 eyes with resolved ME, the cumulative percent with relapse within 7 years was 43% (95% CI, 32-51). Eyes in which ME resolved gained a mean of 6.24 letters (95% CI, 4.40-8.09; P < 0.001) compared with eyes that remained free from ME during the 1-year follow-up intervals, whereas eyes in which ME did not resolve experienced no gain in vision (mean change -1.30 letters; 95% CI, -2.70 to 0.09; P = 0.065), and eyes that developed ME during the year (incident or relapsed) experienced a mean loss of -8.65 letters (95% CI, -11.5 to -5.84, P < 0.001). CONCLUSIONS: Given sufficient time and treatment, nearly all uveitic ME resolves, but episodes of relapse were common. Visual acuity results were better among eyes with resolved ME, suggesting that control of inflammation and resolution of ME might be visually relevant treatment targets.

RESUMEN

TOPIC: An international, expert-led consensus initiative organized by the Collaborative Ocular Tuberculosis Study (COTS), along with the International Ocular Inflammation Society and the International Uveitis Study Group, systematically developed evidence- and experience-based recommendations for the treatment of tubercular choroiditis. CLINICAL RELEVANCE: The diagnosis and management of tubercular uveitis (TBU) pose a significant challenge. Current guidelines and literature are insufficient to guide physicians regarding the initiation of antitubercular therapy (ATT) in patients with TBU. METHODS: An international expert steering subcommittee of the COTS group identified clinical questions and conducted a systematic review of the published literature on the use of ATT for tubercular choroiditis. Using an interactive online questionnaire, guided by background knowledge from published literature, 81 global experts (including ophthalmologists, pulmonologists, and infectious disease physicians) generated preliminary consensus statements for initiating ATT in tubercular choroiditis, using Oxford levels of medical evidence. In total, 162 statements were identified regarding when to initiate ATT in patients with tubercular serpiginous-like choroiditis, tuberculoma, and tubercular focal or multifocal choroiditis. The COTS group members met in November 2018 to refine these statements by a 2-step modified Delphi process. RESULTS: Seventy consensus statements addressed the initiation of ATT in the 3 subtypes of tubercular choroiditis, and in addition, 10 consensus statements were developed regarding the use of adjunctive therapy in tubercular choroiditis. Experts agreed on initiating ATT in tubercular choroiditis in the presence of positive results for any 1 of the positive immunologic tests along with radiologic features suggestive of tuberculosis. For tubercular serpiginous-like choroiditis and tuberculoma, positive results from even 1 positive immunologic test were considered sufficient to recommend ATT, even if there were no radiologic features suggestive of tuberculosis. DISCUSSION: Consensus guidelines were developed to guide the initiation of ATT in patients with tubercular choroiditis, based on the published literature, expert opinion, and practical experience, to bridge the gap between clinical need and available medical evidence.

RESUMEN

TOPIC: The Collaborative Ocular Tuberculosis Study (COTS), supported by the International Ocular Inflammation Society, International Uveitis Study Group, and Foster Ocular Immunological Society, set up an international, expert-led consensus project to develop evidence- and experience-based guidelines for the management of tubercular uveitis (TBU). CLINICAL RELEVANCE: The absence of international agreement on the use of antitubercular therapy (ATT) in patients with TBU contributes to a significant heterogeneity in the approach to the management of this condition. METHODS: Consensus statements for the initiation of ATT in TBU were generated using a 2-step modified Delphi technique. In Delphi step 1, a smart web-based survey based on background evidence from published literature was prepared to collect the opinion of 81 international experts on the use of ATT in different clinical scenarios. The survey included 324 questions related to tubercular anterior uveitis (TAU), tubercular intermediate uveitis (TIU), tubercular panuveitis (TPU), and tubercular retinal vasculitis (TRV) administered by the experts, after which the COTS group met in November 2019 for a systematic and critical discussion of the statements in accordance with the second round of the modified Delphi process. RESULTS: Forty-four consensus statements on the initiation of ATT in TAU, TIU, TPU, and TRV were obtained, based on ocular phenotypes suggestive of TBU and corroborative evidence of tuberculosis, provided by several combinations of immunologic and radiologic test results. Experts agreed on initiating ATT in recurrent TAU, TIU, TPU, and active TRV depending on the TB endemicity. In the presence of positive results for any 1 of the immunologic tests along with radiologic features suggestive of past evidence of tuberculosis infection. In patients with a first episode of TAU, consensus to initiate ATT was reached only if both immunologic and radiologic test results were positive. DISCUSSION: The COTS consensus guidelines were generated based on the evidence from published literature, specialists' opinions, and logic construction to address the initiation of ATT in TBU. The guidelines also should inform public policy by adding specific types of TBU to the list of conditions that should be treated as tuberculosis.

RESUMEN

PURPOSE: The purpose of this study is to determine if statin therapy decreases the incidence of non-infectious uveitis (NIU) using a retrospective cohort study. METHODS: Patients enrolled in a national insurance plan who initiated statin (n = 711,734, statin cohort) or other lipid-lowering therapy (n = 148,044, non-statin cohort) were observed for NIU development. Incident NIU in the primary analysis was defined as a new diagnosis code for NIU followed by a second instance of a NIU code within 120 days. For the secondary outcome definition, a corticosteroid prescription or code for an ocular corticosteroid injection within 120 days of the NIU diagnosis code was used instead of the second NIU diagnosis code. Estimation of NIU incidence used multivariable Cox proportional hazards regression. The proportional hazards assumption was satisfied by creating two time periods of analysis, ≤ 150 and > 150 days. Subanalyses were performed by anatomic subtype. RESULTS: Overall, the primary outcome occurred 541 times over 690,465 person-years in the statin cohort and 103 times over 104,301 person-years in the non-statin cohort. No associations were seen in the ≤ 150-day analyses (p > 0.20 for all comparisons). However, after 150 days, the statin cohort was less likely to develop any uveitis [hazard ratio (HR) = 0.70, 95% confidence interval (CI): 0.51-0.97, P = 0.03] in the primary outcome analysis, but did not meet significance for the secondary outcome (HR = 0.85, 95% CI: 0.63-1.15, P = 0.30). Similarly, in the anatomic subtype analysis, after 150 days, the statin cohort was less likely to develop anterior uveitis (HR = 0.67, 95% CI: 0.47-0.97, P = 0.03) in the primary analysis, but the association did not reach significance for the secondary outcome (HR = 0.82, 95% CI: 0.56-1.20, P = 0.31). CONCLUSION: Our results suggest that statin therapy for > 150 days decreases the incidence of NIU.

RESUMEN

PURPOSE: To determine if female hormonal therapy (FHT) increases the incidence of noninfectious uveitis. DESIGN: Retrospective cohort study. PARTICIPANTS: Women exposed to FHT and matched women unexposed to FHT enrolled in a national insurance plan. METHODS: Estimation of noninfectious uveitis incidence used multivariable Cox proportional hazards regression. To account for differences between the exposed and unexposed cohorts, a propensity score for being prescribed FHT was created using logistic regression, and inverse probability of treatment weighting was performed. MAIN OUTCOME MEASURES: Incidence of noninfectious uveitis. For the primary outcome, incident noninfectious uveitis was defined as a new diagnosis code for noninfectious uveitis followed by a second instance of a noninfectious uveitis code within 120 days. For the alternative outcome definition, a corticosteroid prescription or code for an ocular corticosteroid injection within 120 days of the uveitis diagnosis code was used instead of the second uveitis diagnosis code. RESULTS: There were 217 653 women exposed to FHT and 928 408 women not unexposed to FHT. For the primary outcome, the hazard ratio (HR) for incident noninfectious uveitis was not significantly different between the FHT and unexposed cohorts (HR, 0.99; 95% confidence interval [CI], 0.83-1.17; P = 0.87). With the alternative outcome definition, the FHT cohort was more likely to develop uveitis (HR, 1.21; 95% CI, 1.04-1.41; P = 0.01). When examined by anatomic subtype, for anterior uveitis there was a greater likelihood of incident uveitis in the exposed cohort (HR, 1.23; 95% CI, 1.05-1.45; P = 0.01) for the alternative outcome definition but not for the primary outcome. With age stratification, women exposed to FHT aged ≥45 years at the time of FHT prescription were more likely to develop uveitis (HR, 1.23; 95% CI, 1.03-1.47; P = 0.03) for the alternative outcome definition. A similar HR (1.22) was seen for women aged ≤44 years at the time of prescription, but this association did not meet statistical significance (P = 0.20). CONCLUSIONS: Exposure to FHT increases the rate of incident noninfectious uveitis when uveitis is defined on the basis of both diagnostic codes and documentation of corticosteroid treatment. However, the risk is modest and FHT is likely safe with regard to noninfectious uveitis risk in the majority of patients exposed to these drugs.

RESUMEN

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.

RESUMEN

PURPOSE: To evaluate the comparative effectiveness of 3 regional corticosteroid injections for uveitic macular edema (ME): periocular triamcinolone acetonide (PTA), intravitreal triamcinolone acetonide (ITA), and the intravitreal dexamethasone implant (IDI). DESIGN: Multicenter, randomized clinical trial. PARTICIPANTS: Patients with uveitic ME. METHODS: Patients were randomized 1:1:1 to receive 1 of the 3 therapies. Patients with bilateral ME were assigned the same treatment for both eyes. MAIN OUTCOME MEASURES: The primary outcome was the proportion of baseline (PropBL) central subfield thickness (CST) at 8 weeks (CST at 8 weeks/CST at baseline) assessed with OCT by masked readers. Secondary outcomes included ≥20% improvement and resolution of ME, best-corrected visual acuity (BCVA), and intraocular pressure (IOP) events over 24 weeks. RESULTS: All treatment groups demonstrated improved CST during follow-up. At 8 weeks, each group had clinically meaningful reductions in CST relative to baseline (PropBL: 0.77, 0.61, and 0.54, respectively, which translates to reductions of 23%, 39%, and 46% for PTA, ITA, and IDI, respectively). Intravitreal triamcinolone acetonide (PropBL ITA/PropBL PTA, hazard ratio [HR], 0.79; 99.87% confidence interval [CI], 0.65-0.96) and IDI (PropBL IDI/PropBL PTA, HR, 0.69; 99.87% CI, 0.56-0.86) had larger reductions in CST than PTA (P < 0.0001). Intravitreal dexamethasone implant was noninferior to ITA at 8 weeks (PropBL IDI/PropBL ITA, HR, 0.88; 99.87% CI, 0.71-1.08). Both ITA and IDI treatments also were superior to PTA treatment in improving and resolving uveitic ME. All treatment groups demonstrated BCVA improvement throughout follow-up. Both ITA and IDI groups had improvements in BCVA that was 5 letters greater than in the PTA group at 8 weeks (P < 0.004). The risk of having IOP ≥24 mmHg was higher in the intravitreal treatment groups compared with the periocular group (HR, 1.83; 95% CI, 0.91-3.65 and HR, 2.52; 95% CI, 1.29-4.91 for ITA and IDI, respectively); however, there was no significant difference between the 2 intravitreal treatment groups. CONCLUSIONS: Intravitreal triamcinolone acetonide and the IDI were superior to PTA for treating uveitic ME with modest increases in the risk of IOP elevation. This risk did not differ significantly between intravitreal treatments.

RESUMEN

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.

RESUMEN

IMPORTANCE: A randomized clinical trial comparing fluocinolone acetonide implant vs systemic corticosteroids and immunosuppression for treatment of severe noninfectious intermediate, posterior, and panuveitides did not result in a significant difference in visual acuity at 2 and 4.5 years; longer-term outcomes are not known. OBJECTIVE: To compare the association between intravitreous fluocinolone acetonide implant vs systemic therapy and long-term visual and other outcomes in patients with uveitis. DESIGN, SETTING, AND PARTICIPANTS: Nonprespecified 7-year observational follow-up of the Multicenter Uveitis Steroid Treatment (MUST) randomized clinical trial comparing the alternative treatments. Follow-up was conducted in tertiary uveitis subspecialty practices in the United States (21), the United Kingdom (1), and Australia (1). Of 255 patients 13 years or older with intermediate, posterior, or panuveitis (active within ≤60 days) enrolled in the MUST trial between December 6, 2005, and December 9, 2008, 215 consented to ongoing follow-up through at least 7 years postrandomization (last visit, February 10, 2016). INTERVENTIONS: Participants had been randomized to receive a surgically placed intravitreous fluocinolone acetonide implant or systemic corticosteroids supplemented by immunosuppression. When both eyes required treatment, both eyes were treated. MAIN OUTCOMES AND MEASURES: Primary outcome was change from baseline in best-corrected visual acuity in uveitic eyes (5 letters = 1 visual acuity chart line; potential range of change in letters read, -121 to +101; minimal clinically important difference, 7 letters), analyzed by treatment assignment accounting for nonindependence of eyes when patients had 2 uveitic eyes. Secondary outcomes included potential systemic toxicities of corticosteroid and immunosuppressive therapy and death. RESULTS: Seven-year data were obtained for 161 uveitic eyes (70% of 90 patients assigned to implant) and 167 uveitic eyes (71% of 90 patients assigned to systemic therapy) (77% female; median age at enrollment, 48 [interquartile range, 36-56] years). Change in mean visual acuity from baseline (implant, 61.7; systemic therapy, 65.0) through 7 years (implant, 55.8; systemic therapy, 66.2) favored systemic therapy by 7.2 (95% CI, 2.1-12) letters. Among protocol-specified, prospectively collected systemic adverse outcomes, the cumulative 7-year incidence in the implant and systemic therapy groups, respectively, was less than 10%, with the exceptions of hyperlipidemia (6.1% vs 11.2%), hypertension (9.8% vs 18.4%), osteopenia (41.5% vs 43.1%), fractures (11.3% vs 18.6%), hospitalization (47.6% vs 42.3%), and antibiotic-treated infection (57.4% vs 72.3%). CONCLUSIONS AND RELEVANCE: In 7-year extended follow-up of a randomized trial of patients with severe intermediate, posterior, or panuveitis, those randomized to receive systemic therapy had better visual acuity than those randomized to receive intravitreous fluocinolone acetonide implants. Study interpretation is limited by loss to follow-up. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00132691.

RESUMEN

PURPOSE: To assess the visual outcomes of cataract surgery in eyes that received fluocinolone acetonide implant or systemic therapy with oral corticosteroids and immunosuppression during the Multicenter Uveitis Steroid Treatment (MUST) Trial. DESIGN: Nested prospective cohort study of patients enrolled in a randomized clinical trial. PARTICIPANTS: Patients that underwent cataract surgery during the first 2 years of follow-up in the MUST Trial. METHODS: Visual outcomes of cataract surgery were evaluated 3, 6, and 9 months after surgery using logarithmic visual acuity charts. Change in visual acuity over time was assessed using a mixed-effects model. MAIN OUTCOME MEASURES: Best-corrected visual acuity. RESULTS: After excluding eyes that underwent cataract surgery simultaneously with implant surgery, among the 479 eyes in the MUST Trial, 117 eyes (28 eyes in the systemic, 89 in the implant group) in 82 patients underwent cataract surgery during the first 2 years of follow-up. Overall, visual acuity increased by 23 letters from the preoperative visit to the 3-month visit (95% confidence interval [CI], 17-29 letters; P < 0.001) and was stable through 9 months of follow-up. Eyes presumed to have a more severe cataract, as measured by inability to grade vitreous haze, gained an additional 42 letters (95% CI, 34-56 letters; P < 0.001) beyond the 13-letter gain in eyes that had gradable vitreous haze before surgery (95% CI, 9-18 letters; P < 0.001) 3 months after surgery, making up for an initial difference of -45 letters at the preoperative visit (95% CI, -56 to -34 letters; P < 0.001). Black race, longer time from uveitis onset, and hypotony were associated with worse preoperative visual acuity (P < 0.05), but did not affect postsurgical recovery (P > 0.05, test of interaction). After adjusting for other risk factors, there was no significant difference in the improvement in visual acuity between the 2 treatment groups (implant vs. systemic therapy, 2 letters; 95% CI, -10 to 15 letters; P = 0.70). CONCLUSIONS: Cataract surgery resulted in substantial, sustained, and similar visual acuity improvement in the eyes of patients with uveitis treated with the fluocinolone acetonide implant or standard systemic therapy.

RESUMEN

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.

RESUMEN

PURPOSE: To compare the benefits of fluocinolone acetonide implant therapy versus systemic corticosteroid therapy supplemented (when indicated) with immunosuppression for intermediate uveitis, posterior uveitis, and panuveitis. DESIGN: Additional follow-up of a randomized comparative effectiveness trial cohort. PARTICIPANTS: Two hundred fifty-five patients with intermediate uveitis, posterior uveitis, or panuveitis randomized to implant or systemic therapy. MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA), visual field mean deviation (MD), activity of uveitis, and presence of macular edema (per reading center grading) ascertained prospectively. METHODS: Trial participants were followed-up for 54 months from original randomization. RESULTS: The visual function trajectory in uveitic eyes demonstrated a similar (P = 0.73) degree of modest (not statistically significant) improvement from baseline to 54 months in both groups (mean improvement in BCVA at 54 months, 2.4 and 3.1 letters in the implant and systemic groups, respectively). Many had excellent initial visual acuity, limiting the potential for improvement. The mean automated perimetry MD score remained similar to baseline throughout 48 months of follow-up in both groups. Overall control of inflammation was superior in the implant group at every time point assessed (P < 0.016), although most eyes in the systemic therapy arm also showed substantial improvement, achieving complete control or low levels of inflammation. Although macular edema improved significantly more often with implant treatment within the first 6 months, the systemic group gradually improved over time such that the proportions with macular edema converged in the 2 groups by 36 months and overlapped thereafter (P = 0.41 at 48 months). CONCLUSIONS: Visual outcomes of fluocinolone acetonide implant and systemic treatment for intermediate uveitis, posterior uveitis, and panuveitis were similarly favorable through 54 months. The implant maintained a clear advantage in controlling inflammation through 54 months. Nevertheless, with systemic therapy, most patients also experienced greatly improved inflammatory status. Macular edema improved equally with longer follow-up. Based on cost effectiveness and side-effect considerations, systemic therapy may be indicated as the initial treatment for many bilateral uveitis cases. However, implant therapy is a reasonable alternative, especially for unilateral cases and when systemic therapy is not feasible or is not successful.

RESUMEN

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.

RESUMEN

PURPOSE: To evaluate the risk of cataract in the setting of AIDS. DESIGN: Prospective cohort study. PARTICIPANTS: Subjects with AIDS free of ocular opportunistic infections throughout catamnesis. METHODS: From 1998 through 2008, subjects 13 years of age or older were enrolled. Demographic characteristics and clinical characteristics were documented at enrollment and semiannually. MAIN OUTCOME MEASURES: Cataract was defined as high-grade lens opacity observed by biomicroscopy judged to be the cause of a best-corrected visual acuity worse than 20/40. Eyes that underwent cataract surgery during follow-up were considered to have developed cataract before the first visit when pseudophakia or aphakia was observed. RESULTS: Among 1606 participants (3212 eyes) at enrollment, 1.9% (95% confidence interval [CI]: 1.3%-2.7%) were observed to have cataract or prior cataract surgery. Among the 2812 eyes initially free of cataract and followed longitudinally (median follow-up, 4.6 years), the incidence of cataract was 0.37%/eye-year (95% CI: 0.26%-0.53%). In addition to age, significant cataract risk factors included prior cataract in the contralateral eye (adjusted hazard ratio [aHR], 21.6; 95% CI: 10.4-44.8), anterior segment inflammation (aHR, 4.40; 95% CI: 1.64-11.9), prior retinal detachment (aHR, 4.94; 95% CI: 2.21-11.0), and vitreous inflammation (aHR, 7.12; 95% CI: 2.02-25.0), each studied as a time-updated characteristic. Detectable human immunodeficiency virus RNA in peripheral blood was associated with lower risk of cataract at enrollment (adjusted odds ratio, 0.32; 95% CI: 0.12-0.80) but not of incident cataract (aHR, 1.58; 95% CI: 0.90-2.76). After adjustment for other factors, neither the then-current absolute CD4+ T-cell count nor antiretroviral therapy status showed consistent association with cataract risk, nor did an additive diagnosis of other comorbidities. Compared with the available population-based studies that used similar definitions of cataract, the age-specific prevalence of cataract in our cohort was higher than in 1 of 2 such studies, and the age-specific incidence of cataract surgery was higher. CONCLUSIONS: Our results suggest cataract may occur earlier among patients with AIDS free of ocular opportunistic infections than in the general population. Cataract risk was associated most strongly with age and with other ocular morbidity in this population. With improved survival, the burden of cataract likely will increase for persons with the human immunodeficiency virus or AIDS.

RESUMEN

PURPOSE: To evaluate the reliability of clinical grading of vitreous haze using a new 9-step ordinal scale versus the existing 6-step ordinal scale. DESIGN: Evaluation of diagnostic test (interobserver agreement study). PARTICIPANTS: A total of 119 consecutive patients (204 uveitic eyes) presenting for uveitis subspecialty care on the study day at 1 of 3 large uveitis centers. METHODS: Five pairs of uveitis specialists clinically graded vitreous haze in the same eyes, one after the other using the same equipment, using the 6- and 9-step scales. MAIN OUTCOME MEASURES: Agreement in vitreous haze grade between each pair of specialists was evaluated by the κ statistic (exact agreement and agreement within 1 or 2 grades). RESULTS: The scales correlated well (Spearman's ρ = 0.84). Exact agreement was modest using both the 6-step and 9-step scales: average κ = 0.46 (range, 0.28-0.81) and κ = 0.40 (range, 0.15-0.63), respectively. Within 1-grade agreement was slightly more favorable for the scale with fewer steps, but values were excellent for both scales: κ = 0.75 (range, 0.66-0.96) and κ = 0.62 (range, 0.38-0.87), respectively. Within 2-grade agreement for the 9-step scale also was excellent (κ = 0.85; range, 0.79-0.92). Two-fold more cases were potentially clinical trial eligible on the basis of the 9-step than the 6-step scale (P<0.001). CONCLUSIONS: Both scales are sufficiently reproducible using clinical grading for clinical and research use with the appropriate threshold (≥ 2- and ≥ 3-step differences for the 6- and 9-step scales, respectively). The results suggest that more eyes are likely to meet eligibility criteria for trials using the 9-step scale. The 9-step scale appears to have higher reproducibility with Reading Center grading than clinical grading, suggesting that Reading Center grading may be preferable for clinical trials.

RESUMEN

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.

RESUMEN

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.
