Can Simvastatin Reduce the Need for Immunomodulatory Drugs to Treat Uveitis?: A Prospective, Randomized, Placebo-Controlled Trial.

Objective: To assess the efficacy of simvastatin 80 mg/day versus placebo in patients with noninfectious nonanterior uveitis receiving prednisolone ≥ 10 mg/day. Design: Randomized, double-masked, controlled trial. Subjects: Adult patients with noninfectious nonanterior uveitis on oral prednisolone dose of ≥ 10 mg/day. Methods: Patients were randomly assigned at a 1:1 ratio to receive either simvastatin 80 mg/day or placebo. A total of 32 patients were enrolled (16 in each arm), all of whom completed the primary end point, and 21 reached the 2-year visit (secondary end points). Main Outcome Measures: The primary end point was mean reduction in the daily prednisolone dose at 12 months follow-up. Secondary end points were mean reduction in prednisolone dose at 24 months, percent of patients with a reduction in second-line immunomodulatory agents, time to disease relapse, and adverse events. Results: Our results show that simvastatin 80 mg/day did not have a significant corticosteroid-sparing effect at 12 months (estimate: 3.62; 95% confidence interval [CI]: -8.15 to 15.38; P = 0.54). There was no significant difference between the groups with regard to prednisolone dose or change in dose at 12 and 24 months. There was no difference between the 2 groups in percent of patients with reduction in second-line agent by 24 months. Among patients who achieved disease quiescence, the median time to first relapse was longer for those receiving simvastatin (38 weeks, 95% CI: 14-54) than placebo (14 weeks, 95% CI: 12-52), although this was not statistically significant. There was no significant difference in adverse events or serious adverse events between the 2 groups. Conclusions: Simvastatin 80 mg/day did not have an effect on the dose reduction of corticosteroids or conventional immunomodulatory drugs at 1 and 2 years. The results suggest that it may extend the time to disease relapse among those who achieve disease quiescence.

Uveitis in Sarcoidosis - Clinical Features and Comparison with Other Non-infectious Uveitis.

PURPOSE: Comparison of sarcoid uveitis with other non-infectious uveitis treatment and visual outcomes. METHODS: Retrospective study of 287 eyes with sarcoid uveitis and 1517 eyes with other non-infectious uveitis (15,029 eye-years follow-up). RESULTS: Sarcoid uveitis patients presented at age 43.1 ± 0.8 years, and 66.2% were female. Panuveitis was the most frequent presentation (48.3%), and 90.1% were bilateral. Moderate visual loss (≤20/50) developed in 19 eyes (6.6%), and severe visual loss (≤20/200) in 13 eyes (4.5%). Sarcoid uveitis had better visual outcomes than other non-infectious uveitis (10-year BCVA anterior uveitis 0.06 vs 0.24 p = .002; posterior disease 0.17 vs 0.38 p = .001). Oral corticosteroid use was more common with sarcoid uveitis (anterior uveitis 45.9% vs 16.4% p < .0005; posterior disease 64.0% vs 61.7% p = .635), but second-line immunosuppression was required less frequently (p = .008). CONCLUSIONS: Compared to other non-infectious uveitis, sarcoid uveitis has better visual acuity outcomes and is less likely to require second-line immunosuppression.

Emerging Antibiotic Resistance Patterns Affect Visual Outcome Treating Acute Endophthalmitis.

Background: Examining the effect of antibiotic resistance, use of intravitreal antibiotics and systemic corticosteroids on visual outcome of eyes with acute endophthalmitis. Methods: We included 226 eyes with acute endophthalmitis, treated using a standardized protocol. Visual outcome up to 12 months was assessed related to biopsy results, antibiotics resistance and treatment regimens. Results: Vitreous biopsies were more likely to be culture-positive (41.1%) than anterior chamber biopsies (21.6%, p < 0.0001). Antibiotic resistance for amikacin was found in 19 eyes (24.7%), vancomycin in 29 eyes (31.5%) and moxiflocacin in 14 eyes (16.1%). At presentation 91.53% of eyes had BCVA < 20/40, reducing by 1 month to 69.94% (p < 0.0001) and remaining stable at 12 months. There was no difference in visual outcome for those receiving early systemic corticosteroids. Endophthalmitis following cataract surgery (OR 1.66, 1.04−2.66 95% CI, p = 0.03) and receiving intravitreal vancomycin (OR 3.15, 1.18−8.42 95% CI, p = 0.02) were associated with a greater chance of final BCVA ≥ 20/40. Conclusion: Using vitreous taps with intravitreal antibiotics, despite an increase in resistance to both vancomycin and moxifloxacin, results in a final BCVA > 20/200 in half of eyes and ≥20/40 in a third. Early treatment with intravitreal antibiotics should not be delayed.

Prospective study of morphologic and functional parameter changes post intravitreal therapy for macular edema.

PURPOSE: Retinal sensitivity (RS) can be a valuable indicator of retinal function in response to intravitreal steroid or anti-VEGF treatment in the eyes with diabetic macular edema (DME), macular edema post retinal vein occlusion (RVO), or uveitis. METHODS: This prospective longitudinal study included 68 patients (96 eyes) with macular edema (ME) secondary to diabetes mellitus (42 eyes), uveitis (36 eyes), or RVO (18 eyes). In addition to best corrected visual acuity (BCVA) and retinal thickness, Nidek MP1 microperimetry was used to quantify RS at baseline visit and to look at the mean difference (MD) at 3-6 months and 1-2 years post intravitreal therapy with corticosteroids or anti-VEGF. RESULTS: There was a significant negative correlation between the central RS and BCVA (r = - 0.47, p < 0.001), including DME (r = - 0.42, p = 0.006) and uveitis (r = - 0.60, p < 0.001), but not RVO (r = - 0.37, p = 0.12). At 2-year follow-up, the overall CST was reduced from baseline (MD - 147 µm, 95% C.I - 192 to - 102, p < 0.001) with improved BCVA (MD - 0.12 LogMAR, 95% C.I - 0.23 to - 0.01, p = 0.01), but no improvement in the RS in any of the disorders. Both anti-VEFG and steroid groups showed significant improvement in CST at 2 years from baseline (MD - 101 µm, p = 0.001 and - 167 µm, p < 0.001, respectively) with only improvement in BCVA among anti-VEGF group (MD - 0.16 LogMAR, 95% C.I - 0.26 to - 0.07, p = 0.008). CONCLUSION: The long-term follow-up of ME cases did not show a significant improvement in RS following treatment even with reduced macular thickness at 2-year follow-up.

Outcome and risk of ocular complications of managing children with chronic anterior uveitis with topical rimexolone 1.

PURPOSE: To investigate the efficacy and safety of 1% rimexolone ophthalmic suspension in children with chronic anterior uveitis under real-life conditions in a tertiary center. METHODS: This is a retrospective longitudinal study. Medical records were analyzed at baseline, 1, 3, 6 and 12 months before and after switching to rimexolone for best-corrected visual acuity (BCVA), oral steroid use, number of flares, IOP and anti-glaucoma management. RESULTS: Twenty-four patients (41 eyes) diagnosed with either anterior uveitis (n = 25, 60.0%) or panuveitis (n = 16, 40%) were enrolled. The mean age was 10.5 years (4-16 years). The number of patients requiring oral prednisolone reduced from 8 patients (32.0%) at baseline to 3 patients (20.0%) at 12 months (P < 0.001). Following baseline, the median number of uveitis flares reduced from 2.0 (inter-quartile range (IQR) 1.0-2.75) to 1.0 (IQR 0.0-1.0) compared to the 12 months before baseline (P < 0.001). The mean IOP reduced from baseline (22.0 ± 7.3 mmHg) to 1 month (18.8 ± 8.7 mmHg, P = 0.01) and remained stable up to 12 months (15.9 ± 5.0 mmHg, P < 0.001). Average BCVA, dose of oral prednisolone and anti-glaucoma treatments did not change compared to the baseline. The development for IOP ≥ 30 mmHg was associated with a known corticosteroid response [odds ratio (OR) 6.8, P = 0.003] and a dose > 7.5 mg/day oral prednisolone (OR 4.4, P = 0.033). CONCLUSIONS: Rimexolone 1% ophthalmic suspension is an effective and safe topical steroid for pediatric anterior uveitis.

Differentiating Multifocal Choroiditis and Punctate Inner Choroidopathy: A Cluster Analysis Approach.

PURPOSE: To develop a robust approach to clinical phenotyping of multifocal choroiditis (MFC) and punctate inner choroidopathy (PIC). DESIGN: Cross-sectional and longitudinal observational study. METHODS: This multicenter study included sites in the United Kingdom and Israel. The study population included 343 eyes of 185 subjects with hospital record diagnoses of MFC or PIC. Eyes were observed over a period of 5 years for clinically relevant characteristics, including demographics and multimodal imaging features, by observers masked to the original diagnoses. Multivariate 2-step cluster analysis was used to identify clusters of eyes in the database with similar clinical phenotypes, which were then analyzed for between-group differences. The primary outcome measure was the difference between clinical phenotype clusters identified using clinical criteria from the multivariate cluster analysis. RESULTS: Subjects ranged from 11 to 89 years of age, with a baseline best-corrected visual acuity of 2.3 to -0.2 logarithm of minimal angle of resolution. Eighty-two percent of eyes were from females, 74% were myopic with a refractive error of +3.00 to -17.00 diopters (spherical equivalent). Cluster analysis prioritized clinical criteria of chorioretinal lesion location and intraocular inflammation and identified 2 distinct phenotype clusters resembling the original descriptions of MFC and PIC. During the 5-year period of observation, the initial clinical diagnosis remained stable for most eyes and only 1 eye (0.3%) changed diagnosis from PIC to MFC because of newly developed peripheral lesions. There were significant between-group differences in clinical characteristics, for example, in choroidal neovascular membrane development and treatment received. CONCLUSIONS: Cluster analysis of this large cohort of eyes identified peripheral lesions and intraocular inflammation as distinct clinical phenotypes of MFC and PIC. The initial diagnosis remained stable for most eyes. This methodology could be useful for future uveitis classification and management.

Long-Term Outcomes of Treatment with Biological Agents in Eyes with Refractory, Active, Noninfectious Intermediate Uveitis, Posterior Uveitis, or Panuveitis.

PURPOSE: To examine a large cohort of patients treated with biologic agents for active noninfectious intermediate uveitis, posterior uveitis, or panuveitis (NIPPU) and to compare their efficacy and long-term effect. DESIGN: Retrospective, longitudinal study. PARTICIPANTS: Eighty-two patients (156 eyes) with active NIPPU after failure of treatment with corticosteroids and a second-line immunosuppression drug and treated with biologic agents who were treated at Moorfields Eye Hospital between 2001 and 2016. METHODS: Information was gathered from the clinical notes of all patients. MAIN OUTCOME MEASURES: Time to first disease flare, rate of treatment failure, best-corrected visual acuity, and risk factors for treatment failure. RESULTS: Patients were followed on average for 4.7±0.4 years (724 eye-years). All patients demonstrated active uveitis at baseline, and 34 patients (41.5%) demonstrated a coexisting active systemic disease. Control of ocular inflammation was achieved in 136 eyes (87.2%). The average oral prednisolone dose at baseline was 16.4±1.7 mg/day, and by 6 months reduced to 6.5±0.7 mg/day (P < 0.0001), remaining stable for up to 5 years follow-up. Best-corrected visual acuity at baseline was 0.5±0.1 logarithm of the minimum angle of resolution (logMAR), improved to 0.4±0.1 logMAR (P = 0.008) at 3 months, and remained stable during follow-up. After baseline, 42.3% of eyes experienced flares, and the average number of flares reduced from 1.8±0.1 flares/year to 0.6±0.1 flares/year (P < 0.0001). Median time to first flare was 5.4 years (95% confidence interval [CI], 2.2-5.4 years) with a 5-year survival rate of 58.7%. Treatment failed in 37 eyes (23.7%), with a 5-year survival rate of 68.0% and an estimated time to 75% survival of 2.9 years (95% CI, 2.1-4.4 years). The risk for treatment failure was lower when treatment used adalimumab (odds ratio, 0.4; 95% CI, 0.2-0.9; P = 0.03) but was greater when systemic disease also was active at baseline (odds ratio, 3.2; 95% CI, 1.5-7.1; P = 0.004). CONCLUSIONS: Overall, eyes treated with biologic agents after failure of treatment with corticosteroids and a second-line immunosuppression drug experienced satisfactory disease control (87.2%), reduced use of systemic immunosuppression, stable visual acuity, and a 23.7% risk of disease relapse. After multivariate adjustment, older age, treatment with adalimumab (versus infliximab), and inactive concomitant systemic disease were associated with a lower risk of treatment failure.

Long-term effect of cataract phacoemulsification on the inflammation control and clinical outcome in uveitis patients.

IMPORTANCE: Cataract is one of the most common complications associated with uveitis, and is the leading cause of vision loss in these patients. BACKGROUND: The study aimed to evaluate the effect of phacoemulsification on the long-term clinical outcome and inflammation control in uveitis patients. DESIGN: Longitudinal study. PARTICIPANTS: Of 1907 eyes with uveitis, 309 eyes underwent phacoemulsification were compared to a control group of 300 phakic eyes with uveitis. METHOD: The risk of vision loss and macular oedema in pseudophakic eyes were compared to the phakic group. The rates of corticosteroids administration and uveitis relapse were also measured in pseudophakic eyes and compared to preoperative period. MAIN OUTCOME MEASURES: Change in uveitis activity post phacoemulsification by measuring rate of uveitis relapse and use of topical and systemic steroids. Also, to measure the risk of vision loss and macular oedema post surgery. RESULTS: Over a median follow-up time of 6.7 years or 2249 eye-years (EY), pseudophakic eyes had a greater risk of vision loss (hazard ratio [HR] 2.4, CI 1.4 to 4.0; P < 0.001) and macular oedema (HR 2.2, CI 1.4 to 3.4, P < 0.001) compared to the phakic uveitis group. Over 5 years post-surgery, the annual rate of uveitis relapses was less than the same period pre surgery (-1.2, 95% CI -2.0 to -0.2, P = 0.012) with no significant change in the annual rate of using topical and systemic prednisolone >7.5 mg/day. CONCLUSIONS AND RELEVANCE: There was no significant increase in uveitis relapse rate post-phacoemulsification with the use of current prophylactic inflammation control measures.

Clinical Outcome of Retinal Vasculitis and Predictors for Prognosis of Ischemic Retinal Vasculitis.

PURPOSE: To determine factors affecting the visual outcome in eyes with retinal vasculitis and the rate of neovascularization relapse in ischemic vasculitis. DESIGN: Retrospective cohort study. METHODS: We reviewed 1169 uveitis patients from Moorfields Eye Hospital, London, UK. Retinal vasculitis was observed in 236 eyes (121 ischemic, 115 nonischemic) that were compared with a control group (1022 eyes) with no retinal vasculitis. Ultra-widefield fluorescein angiography images were obtained in 63 eyes with ischemic vasculitis to quantify area of nonperfusion measured as ischemic index. RESULTS: The risk of vision loss was significantly more in the retinal vasculitis compared with the non-vasculitis group (hazard ratio [HR] 1.67, 95% confidence interval [CI] 1.24-2.25, P = .001). Retinal vasculitis had twice the risk of macular edema compared to the non-vasculitis group. Macular ischemia increased the risk of vision loss in vasculitis eyes by 4.4 times. The use of systemic prednisolone in eyes with vasculitis was associated with a reduced risk of vision loss (HR 0.36, 95% CI 0.15-0.82, P = .01). Laser photocoagulation was administered in 75 eyes (62.0%), out of which 29 (38.1%) had new vessel relapse and required additional laser treatment. The median ischemic index was 25.8% (interquartile range 10.2%-46%). Ischemia involving ≥2 quadrants was associated with increased risk of new vessel formation (HR 2.7, 95% CI 1.3-5.5, P = .003). CONCLUSIONS: Retinal vasculitis is associated with an increased risk of vision loss, mainly secondary to macular ischemia, and has a higher risk of macular edema compared to eyes with no vasculitis. Ischemia involving ≥2 quadrants is a risk factor for new vessel formation.

Risk Factors for the Development of Cataract in Children with Uveitis.

PURPOSE: To determine the risk factors for the development of cataract in children with uveitis of any etiology. DESIGN: Cohort study. METHODS: Two hundred forty-seven eyes of 140 children with uveitis were evaluated for the development of vision-affecting cataract. Demographic, clinical, and treatment data were collected between the time of presentation and the first instance cataract was recorded or findings at final follow-up. Main outcome measures included the prevalence of cataract and distribution by type of uveitis, incidence of new onset cataract time to cataract development, and risk factors for the development of cataract. RESULTS: The prevalence of cataract in our cohort was 44.2% and was highest among eyes with panuveitis (77.1%), chronic anterior uveitis (48.3%), and intermediate uveitis (48.0%). The overall incidence of newly diagnosed cataract was 0.09 per eye-year, with an estimated 69% to develop uveitis-related cataract with time. The main factors related with cataract development were the number of uveitis flares per year (hazard ratio [HR] = 3.06 [95% confidence interval {CI}, 2.15-4.35], P < .001), cystoid macular edema (HR = 2.87 [95% CI, 1.41-5.82], P = .004), posterior synechia at presentation (HR = 2.85 [95% CI, 1.53-5.30], P = .001), and use of local injections of corticosteroids (HR = 2.37 [95% CI, 1.18-4.75], P = .02). Treatments with systemic and topical corticosteroids were not significant risk factors. CONCLUSIONS: In this study, we found that development of cataract is common among pediatric eyes with uveitis and is most strongly related to the extent of inflammation recurrences and ocular complications. We suggest that controlling the inflammation, even using higher doses of systemic and topical corticosteroids, is of importance in preventing ocular complications, such as cataract.

Predictors of Long-Term Visual Outcome in Intermediate Uveitis.

PURPOSE: To describe factors that predict visual loss and complications in intermediate uveitis. DESIGN: Cross-sectional study. PARTICIPANTS: Subjects with intermediate uveitis were identified from a database of 1254 uveitis patients seen in the clinic of a single consultant (S.L.L.) between 2011 and 2013. METHODS: Information was gathered from the clinical notes of all subjects examined in clinic. MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA), moderate visual loss (MVL; ≤20/50), severe visual loss (SVL; ≤20/200). RESULTS: Three hundred and five subjects (550 eyes) were included in the study, comprising 24.3% of subjects seen in clinic. Mean (± standard deviation) age at diagnosis was 40.9±16.9 years, and 64.6% of subjects were female. Median follow-up was 8.2 years (mean, 9.7 years, 5452 eye-years). Systemic diagnosis was made in 36.1% of patients, with sarcoidosis (22.6%) and multiple sclerosis (4.6%) the most frequent systemic associations. Median BCVA was 20/30 (mean logarithm of the minimum angle of resolution [logMAR] 0.26±0.38, n = 550 eyes) at presentation, 20/30 (mean logMAR 0.22±0.42, n = 430) at 5 years, and 20/30 (mean logMAR 0.23±0.46, n = 260) at 10 years. Macular edema was observed in 224 eyes (40.7%) and was associated with idiopathic disease (P = 0.001) and diabetes (P = 0.001). Topical therapy was used in 82.7%, and 34.2% received local injections of corticosteroids. A total of 50.5% required oral steroids and 13.8% required second-line immunosuppression. Subjects with a diagnosis of sarcoidosis were less likely to require a second-line agent (4.3% vs. 16.2%, P = 0.011). On multivariate analysis, visual acuity at referral, retinal pigment epithelial atrophy, and macular scarring were associated with increased risk of MVL; and visual acuity at referral, local therapy, macular scarring, retinal detachment, and hypotony and phthisis were associated with increased risk of SVL. CONCLUSIONS: Intermediate uveitis has a long disease course with frequent complications and often requires systemic treatment. Despite this, most subjects are still able to achieve good long-term visual outcomes.
