Incidence and remission of post-surgical cystoid macular edema following cataract surgery in eyes with intraocular inflammation.

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 18-44 and aOR 1.93 for ages 45-64, overall p = 0.02); concurrent use of systemic immunosuppression (conventional aOR 1.53 and biologics aOR 2.68, overall p =0.0095); pre-operative VA 20/50 or worse (overall p <0.0001); cataract surgery performed before 2000 (overall p=0.03) and PMCE in fellow eye (aOR 3.04, p=0.0004) 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.

Posterior capsular opacification and YAG laser capsulotomy in uveitis patients following cataract surgery.

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 p = 0.03). Poorer preoperative visual acuity (overall p = 0.0069) and postoperative inflammation (odds ratio [OR] = 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] = 1.90-2.24; 95% CI, 1.90-2.24; overall p = 0.0007), female sex (aOR = 1.37; 95% CI, 1.03-1.82; p = 0.03), postoperative active inflammation (aOR = 165; 95% CI, 1.27-2.16; overall p < 0.0001), extracapsular cataract extraction compared with phacoemulsification (aOR = 1.70; 95% CI, 1.17-2.47; overall p < 0.0001), and insertion of an intraocular lens (aOR = 4.60; 95% CI, -2.29-9.25; p < 0.0001). Black race was associated with lower YAG laser capsulotomy incidence than Whites (aOR = 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.

Successful Treatment of Clinically Diagnosed Cancer-Associated Retinopathy with Intravitreal Dexamethasone Implant Followed by 0.18 mg Fluocinolone Implant without Systemic Immunosuppression.

PURPOSE: To report a case of clinically diagnosed cancer-associated retinopathy (CAR) successfully treated with intravitreal corticosteroid implants without systemic immunosuppression. METHODS: Case report with multimodal imaging. RESULTS: An 80-year-old man without known systemic malignancy presented with debilitating shimmering, hemeralopia and rapidly progressive bilateral vision loss following uncomplicated cataract surgery. Mild vitritis, extensive photoreceptor loss, mottling of retinal pigmentary epithelium (RPE), and mild vascular attenuation were found in both eyes. Full field electroretinogram (ffERG) showed severe bilateral rod-cone dysfunction. Infectious etiologies and vitreoretinal lymphoma were ruled out. During cancer workup, intravitreal corticosteroid treatment was offered. Significant anatomical improvement with reconstitution of ellipsoid zone, improved RPE irregularities and functional improvement, were observed 3 weeks after bilateral intravitreal dexamethasone implants (Ozurdex). 2 months later, patient received bilateral intravitreal 0.18mg fluocinolone acetonide implants (YUTIQ). Later, a colonic adenocarcinoma was found (pathologic stage pT3 pN0). Patient recovered well from surgery and no chemotherapy was needed. 9 months since bilateral intravitreal fluocinolone acetonide implants (11 months since bilateral intravitreal dexamethasone implants), best corrected vision maintained at 20/25-2 OD, 20/20 OS without ongoing treatments. Bilateral reconstitution of ellipsoid zones and nearly resolution of RPE irregularities remained stable. Repeat ffERG demonstrated improved cone response OS and stable diminished rod response OU. Patient reports resolution of ocular symptoms. CONCLUSION: The sustained improvements with intravitreal corticosteroid monotherapy suggest potential advantages using local therapy over systemic treatment. Long term follow-up is warranted. Further research is needed to evaluate the efficacy of using 0.18mg fluocinolone implant (YUTIQ) to treat CAR.

Long-term visual acuity outcomes following cataract surgery in eyes with ocular inflammatory disease.

PURPOSE: To evaluate the long-term visual acuity (VA) outcome of cataract surgery in inflammatory eye disease. SETTING: Tertiary care academic centres. DESIGN: Multicentre retrospective cohort study. METHODS: A total of 1741 patients with non-infectious inflammatory eye disease (2382 eyes) who underwent cataract surgery while under tertiary uveitis management were included. Standardised chart review was used to gather clinical data. Multivariable logistic regression models with adjustment for intereye correlations were performed to evaluate the prognostic factors for VA outcomes. Main outcome measure was VA after cataract surgery. RESULTS: Uveitic eyes independent of anatomical location showed improved VA from baseline (mean 20/200) to within 3 months (mean 20/63) of cataract surgery and maintained through at least 5 years of follow-up (mean 20/63). Eyes that achieved 20/40 or better VA at 1 year were more likely to have scleritis (OR=1.34, p<0.0001) or anterior uveitis (OR=2.2, p<0.0001), VA 20/50 to 20/80 (OR 4.76 as compared with worse than 20/200, p<0.0001) preoperatively, inactive uveitis (OR=1.49, p=0.03), have undergone phacoemulsification (OR=1.45 as compared with extracapsular cataract extraction, p=0.04) or have had intraocular lens placement (OR=2.13, p=0.01). Adults had better VA immediately after surgery, with only 39% (57/146) paediatric eyes at 20/40 or better at 1 year. CONCLUSIONS: Our results suggest that adult and paediatric eyes with uveitis typically have improved VA following cataract surgery and remain stable thereafter for at least 5 years.

Late diagnosis of Cutibacterium acnes (formerly Proprionibacterium acnes) endophthalmitis and the importance of dual testing with bacterial culture and polymerase chain reaction.

PURPOSE: To describe two cases of C. acnes endophthalmitis that reinforce the importance of performing both bacterial culture and 16s polymerase chain reaction when the causative pathogen is unclear or difficult to culture, such as C. acnes. A case of C. acnes endophthalmitis complicated by sub-buckle scleral perforation is illustrated with intraoperative photography. METHODS: Two-case series. RESULTS: Case 1 describes a case of C. acnes endophthalmitis in a longstanding pseudophakic patient following multiple vitrectomies for recurrent retinal detachment, complicated by sub-buckle scleral perforation. Bacterial culture revealed C. acnes while 16s PCR was negative. Conversely, Case 2 demonstrates a case of chronic endophthalmitis diagnosed one year following cataract surgery. PCR (with repeat tap for confirmation) revealed C. acnes with a negative culture. CONCLUSION: When the causative pathogen of endophthalmitis is unclear, dual testing of microbial culture and C. acnes 16s PCR improves the diagnostic yield of investigations for fastidious pathogens. C. acnes can present as an indolent or virulent endophthalmitis.

Use of Immunosuppression and the Risk of Subsequent Overall or Cancer Mortality.

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.

Incidence of and Risk Factors for Cataract in Anterior 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 ∼5.4/100 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.

Risk of failing both methotrexate and mycophenolate mofetil from the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial.

BACKGROUND: The antimetabolites methotrexate (MTX) and mycophenolate mofetil (MMF) are commonly used as initial corticosteroid-sparing treatment for uveitis. There is little data examining risk factors for failing both MTX and MMF. The objective of this study is to determine risk factors for failing both MTX and MMF in patients with non-infectious uveitis. MAIN BODY: This is a sub-analysis of the First-line Antimetabolites as Steroid-sparing Treatment (FAST) uveitis trial, which was an international, multicenter, block-randomized, observer-masked, comparative effectiveness trial comparing MTX and MMF as initial treatments for non-infectious uveitis. This study was undertaken at multiple referral centers in India, the United States, Australia, Saudi Arabia and Mexico between 2013 and 2017. A total of 137 patients who completed all 12 months of follow-up from the FAST trial, were included in this study. The primary outcome was failing both antimetabolites over the 12 months of the trial. Potential predictors included: age, sex, bilateral involvement, anatomic location of the uveitis, presence of cystoid macular edema (CME) and retinal vasculitis at baseline visit, uveitis duration, and country/study sites as risk factors for failing both MTX and MMF. The presence of retinal vasculitis posterior to the equator on fluorescein angiogram was associated with failing both MTX and MMF. CONCLUSION: Retinal vasculitis may be a risk factor for failing multiple antimetabolites. Clinicians could consider more quickly advancing these patients to other medication classes, such as biologics.

Risk Factors Associated with Unexpected Refractive Outcomes in Uveitic Cataract Surgery.

OBJECTIVE: Assess refractive outcomes following uveitic cataract surgery and identify factors associated with deviations from the target refractive goal. METHODS: A multicenter retrospective chart review was performed for 216 subjects with uveitis undergoing cataract surgery. Prediction error was calculated and tested for association with demographic and clinical characteristics using single variable and multiple regression analysis. RESULTS: 39.8% of eyes deviated from the intended refractive target by at least 0.5 diopters (D). The mean prediction error was 0.56 ± 0.67 D. Younger age (p = 0.042), preoperative inflammatory corneal findings (keratic precipitates and/or band keratopathy) (p = 0.0004), and poorer postoperative visual acuity (p = 0.0054) were associated with a deviation from the intended refractive target by at least 1 D. CONCLUSIONS: A higher percentage of eyes undergoing uveitic cataract surgery deviated from the intended refractive target when compared to reported refractive outcomes in normal subjects. Younger age, preoperative inflammatory corneal sequelae, and poorer postoperative visual acuity were associated with this outcome.

Outcomes of Uveitic Macular Edema in the First-line Antimetabolites as Steroid-Sparing Treatment Uveitis Trial.

PURPOSE: To evaluate the outcomes of uveitic macular edema at 6 and 12 months in patients treated with methotrexate or mycophenolate mofetil. DESIGN: Subanalysis of a block-randomized, observer-masked, multicenter clinical trial. PARTICIPANTS: Patients were enrolled in the First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial between August 2013 and August 2017. METHODS: Patients were randomized to oral methotrexate 25 mg weekly or mycophenolate mofetil 1.5 g twice daily for 12 months, along with a corticosteroid taper. In addition to standardized clinical examination, all patients underwent spectral-domain OCT imaging at each visit. At the 6-month primary end point, patients who achieved treatment success continued the same treatment for a subsequent 6 months, and treatment failures switched to the other treatment group. MAIN OUTCOME MEASURES: Prespecified 6-month primary outcome and 12-month outcomes of central subfield thickness and visual acuity. RESULTS: Of 216 patients in the FAST Trial, 42 eyes (30 patients) in the methotrexate group and 55 eyes (41 patients) in the mycophenolate group had uveitic macular edema. Baseline median central subfield thickness was 359 µm and 342 µm in the methotrexate and mycophenolate groups, respectively. At 12 months, for those who stayed on the same treatment, macular thickness decreased from baseline by 30.5 µm (interquartile range [IQR], -132.3 to 4.0) and 54 µm (IQR, -95.5 to -4.5) in the methotrexate and mycophenolate groups, respectively (P = 0.73). In patients who switched treatment at 6 months, macular thickness decreased from baseline by 12.5 µm (IQR, -32.3 to -0.5) and 50 µm (IQR, -181.0 to -10.0) in the methotrexate and mycophenolate groups, respectively (P = 0.34). At 12 months, 7 of 19 eyes (37%) on methotrexate had resolution of macular edema compared with 15 of 25 eyes (60%) on mycophenolate (P = 0.10). For those who switched treatments, 8 of 17 eyes (47%) on methotrexate and 6 of 11 eyes (55%) on mycophenolate had resolution of macular edema (P = 0.92). CONCLUSIONS: Treatment with methotrexate or mycophenolate mofetil for uveitic macular edema results in similar improvements in macular thickness at 6 and 12 months. At 12 months, approximately half of eyes in each antimetabolite group still had persistent macular edema.

Extension study of the safety and efficacy of CLS-TA for treatment of macular oedema associated with non-infectious uveitis (MAGNOLIA).

PURPOSE: To assess the extended efficacy and safety of suprachoroidal triamcinolone acetonide injectable suspension (CLS-TA) among patients with macular oedema (ME) secondary to non-infectious uveitis (NIU). METHODS: Patients with uveitic ME were treated with suprachoroidal CLS-TA at baseline and week 12 of the Efficacy and Safety of Suprachoroidal CLS-TA for Macular Edema Secondary to Noninfectious Uveitis: Phase 3 Randomized Trial (PEACHTREE) study. Time to rescue was evaluated over 24 additional weeks for MAGNOLIA. Safety data, visual acuity and retinal central subfield thickness (CST) reduction were also evaluated. Of the 53 eligible patients (46 CLS-TA and 7 control), 33 patients were enrolled (28 CLS-TA and 5 control). RESULTS: Over the entire 48-week period for PEACHTREE and MAGNOLIA, the median time to rescue therapy was 257 days versus 55.5 days for the CLS-TA and sham-control arms, respectively. Of 28 CLS-TA treated patients who participated in MAGNOLIA, 14 (50%) did not require rescue therapy through approximately 9 months after the second treatment. Among CLS-TA patients not requiring rescue, there was a mean gain of 12.1 letters and mean CST reduction of 174.5 µm at week 48. No serious adverse events related to study treatment were observed. CONCLUSION: Approximately 50% of patients did not require additional treatment for up to 9 months following the last CLS-TA administration.

Corneal Endothelial Transplantation in Uveitis: Incidence and Risk Factors.

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.

Risk of Cataract in Intermediate Uveitis.

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.

Contemporaneous Risk Factors for Visual Acuity in Non-Infectious Uveitis.

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.

Treatment of Refractory Cystoid Macular Edema with Pegylated Interferon Alfa-2A: A Retrospective Chart Review.

Purpose: To determine the efficacy of pegylated interferon alfa-2A in the treatment of refractory inflammatory cystoid macular edema (CME)Methods: Retrospective chart reviewResults: Treatment with pegylated interferon alfa-2A led to an improvement in CME in all eyes of seven included patients, with a mean decrease in CMT from 478 µm to 310 µm (p < .05). The vision in one patient did not improve due to preexisting retinal atrophy. All other eyes showed improvement in vision, with a mean improvement in best LogMAR visual acuity from +0.59 to +0.28 (p < .05). The treatment effect was sustained with low-dose treatment every 2 weeks or less in the majority of patients. Two patients who stopped interferon treatment given flu-like symptoms and intolerable rash, respectively, showed rapid recurrence of CME.Conclusions: Weekly administration of pegylated interferon alfa-2A is an effective treatment for refractory inflammatory CME, though side effects may limit tolerability in some patients.

Remission of Non-Infectious Anterior Scleritis: Incidence and Predictive Factors.

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.

Factors Predictive of Remission of Chronic Anterior Uveitis.

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.

Inferior Corneal Haze and Inflammatory Endotheliopathy Related to Pars Planitis.

PURPOSE: To describe the finding of inferior corneal haze secondary to presumed inflammatory endothelio-10 pathy in a series of patients with pars planitis. METHODS: Single-center retrospective observational consecutive case-series. RESULTS: Seven patients with an established diagnosis of pars planitis are described in this case series including four females and three males. The ages ranged from 5 to 31 years at presentation. Pars planitis was bilateral in six patients and unilateral in one patient. Fundus examinations revealed vitreous opacities and pars plana exudates in all seven patients, cystoid macular edema in four patients, and peripheral retinal vasculitis in two patients. Corneal examination revealed opacification of the posterior cornea in an inferior location in 10 of the 13 eyes with pars planitis. Only one of these eyes had keratic precipitates. For a given patient, corneal involvement was more commonly seen in the more inflamed eye. In one patient with active inflammation, microcystic corneal edema was noted to predate the formation of inferior corneal endothelial opacification, suggesting that physical proximity to the site of inflammation at the inferior pars plana is the cause of this notable physical finding. CONCLUSIONS: Inferior posterior corneal haze related to inflammatory endotheliopathy may occur in eyes with pars planitis. As patients with pars planitis may be otherwise asymptomatic, this corneal finding shouldprompt a detailed funduscopic examination to rule out this form of uveitis.

Association of Fundus Autofluorescence Findings and Outer Retinal Lesions on Optical Coherence Tomography With Visual Acuity in Birdshot Chorioretinopathy.

PURPOSE: This article investigates the optical coherence tomography (OCT) and fundus autofluorescence imaging findings in birdshot chorioretinopathy (BSCR) and their association with visual acuity (VA). METHODS: In a retrospective, cross-sectional study, we evaluated OCT images for changes in retinal structure including cystoid macular edema (CME), epiretinal membrane, and outer retinal lesions. We assessed autofluorescence images for hypoautofluorescent and hyperautofluorescent changes and noted the distribution of the lesions. Demographic data and VA at the time of imaging were also collected. Associations between OCT and autofluorescence findings and logarithm of the minimum angle of resolution VA were tested using linear regression. RESULTS: We conducted a chart review of 80 eyes from 40 patients with BSCR. Outer retinal lesions were found on OCT in 28 of 80 eyes (35%) and disruption of the outer segment ellipsoid zone (EZ) occurred in 23 eyes (28.7%). Macular hypoautofluorescent lesions were more common than hyperautofluorescent lesions, present in 58.8% and 13% of eyes, respectively. The presence of outer retinal lesions on OCT was significantly associated with reduced VA (P = .006) as was EZ disruption (P = .003). These associations remained significant after accounting for the presence of macular edema. There was a trend toward association of macular hypoautofluorescent lesions with decreased vision, although it was not statistically significant (P = .17). CONCLUSIONS: The association of outer retinal lesions with decreased VA suggests a mechanism of central vision loss that is distinct from CME and may provide an additional objective finding to monitor disease activity in BSCR patients.

The Impact and Implication of Peripheral Vascular Leakage on Ultra-Widefield Fluorescein Angiography in Uveitis.

Purpose: To study if peripheral vascular leakage (PVL) on ultra-widefield fluorescein angiography (UWFFA) prognosticates complications of uveitis or necessitates treatment augmentation. Methods: Retrospective cohort study of uveitis patients imaged with UWFFA and ≥1 yr of follow-up. Results: We included 73 eyes of 42 patients with uveitis. There was no difference in baseline, intermediate, final visual acuity (p = 0.47-0.95) or rates of cystoid macular edema (CME) (p = 0.37-0.87) in eyes with PVL vs. those without. Eyes with PVL receiving baseline treatment augmentation were more likely to have baseline CME but were not more likely to have impaired visual acuity at final follow-up. PVL was independently associated with treatment augmentation on generalized estimating equation analysis with multivariable linear regression (OR: 4.39, p = 0.015). Conclusions: PVL did not confer an increased risk of impaired VA or CME at ≥1 yr follow-up but was possibly an independent driver of treatment augmentation.
