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.

Phase 1 Study of JNJ-81201887 Gene Therapy in Geographic Atrophy Secondary to Age-related Macular Degeneration.

OBJECTIVE: To evaluate the safety and tolerability of a single intravitreal injection of JNJ-81201887 (JNJ-1887) in patients with geographic atrophy (GA) secondary to advanced dry age-related macular degeneration (AMD). DESIGN: Phase 1, open-label, single-center, first-in-human clinical study. SUBJECTS: Adult patients (aged ≥50 years) with GA secondary to AMD in the study-treated eye (treated eye) with a best corrected visual acuity (BCVA) Snellen equivalent of 20/200 or worse in the treated eye (20/80 or worse after the first 3 patients), a total GA lesion size between 5 and 20 mm2 (2-8 disc area), and BCVA of 20/800 or better in fellow, non-treated eye were included. METHODS: Patients (N=17) were sequentially enrolled into low (3.56×1010 viral genome [vg]/eye; n=3), intermediate (1.07×1011 vg/eye; n=3), and high (3.56×1011 vg/eye; n=11) dose cohorts without steroid prophylaxis and assessed for safety and tolerability over 24 months. MAIN OUTCOME MEASURES: Safety and tolerability outcomes included assessment of ocular and non-ocular treatment-emergent adverse events (AEs) over 24 months. Secondary outcomes included GA lesion size and growth rate. RESULTS: Baseline patient characteristics were consistent with the disease under study, and all enrolled patients had foveal center-involved GA. JNJ-1887 was well tolerated across all cohorts, with no dose-limiting AEs. There were no serious or systemic AEs related to study intervention. Overall, 5/17 (29%) patients experienced 6 events of mild ocular inflammation related to study treatment; exam findings in all resolved, and AEs resolved in 4 of 5 patients following topical steroids or observation. One unresolved vitritis event, managed with observation, occurred in a patient with an unrelated fatal AE. No endophthalmitis or new-onset choroidal neovascularization was reported. GA lesion growth rate was similar among all cohorts over 24 months. For treated eyes in the high-dose cohort, GA lesion growth rate showed continued decline through 24 months, with a reduction in mean square root lesion growth from 0.211 mm at months 0-6 to 0.056 mm at months 18-24. CONCLUSIONS: All 3 studied doses of JNJ-1887 had a manageable safety profile through 24 months of follow-up. Further investigation of JNJ-1887 for the treatment of GA is warranted.

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.

Treatment Outcomes of Intravitreal Aflibercept for Uveitic Macular Edema.

BACKGROUND/AIMS: To evaluate the efficacy of intravitreal aflibercept for UME (uveitic macular). METHODS: A retrospective review of records of patients that received aflibercept for UME from January 2017 to August 2022 was conducted. The primary outcomes were mean change in visual acuity (VA) and central subfield thickness (CST) 6 and 12 months from the start of aflibercept treatment. RESULTS: A total of 16 eyes of 12 patients were included. Indications for treatment included eyes that had previously demonstrated a history of elevated intraocular pressure secondary to a steroid response (n = 10) or a history of non-response or partial response to local corticosteroids (n = 6). Fifteen eyes (94%) demonstrated a reduction in CST after their initial injection. At 6-months, mean VA gain was 2.6 ± 7.7 letters (p = 0.24) from a mean VA of 67.8 ± 10.7 letters at baseline and mean CST improved by 97.6 ± 113.5 µm (p = 0.004) from 458.6 ± 123.1 µm at baseline. Fourteen eyes had 12-months of follow up and received a median of 4 injections over 12 visits. The mean VA at 12-months remained stable compared to baseline (mean change of -1.4 ± 12.5 letters (p = 0.87)) while the CST improved by a mean of 90.9 ± 114.6 µm (p = 0.053) compared to baseline. CONCLUSION: Intravitreal aflibercept injections resulted in reduced central subfield thickness at all time-points. It appears to be an effective treatment alternative for UME, particularly for patients who are not responsive to local corticosteroids or who have contraindications to corticosteroid treatment.

Ultrawide-field fluorescein angiography features in patients with anterior uveitis.

PURPOSE: To evaluate the utility of ultrawide-field fluorescein angiography (UWFFA) in patients with anterior uveitis by investigating the detection of retinal vascular leakage (RVL) and the subsequent implications on disease diagnosis and management. STUDY DESIGN/MATERIALS AND METHODS: Patients, who were referred to the National Eye Institute (NEI) for evaluation of anterior uveitis and underwent UWFFA imaging at the initial visit, were included in this study. The electronic medical records of eligible patients were reviewed. The UWFFA images were assessed for severity of retinal vascular leakage, presence of macular leakage, and optic disc leakage by a two-grader system, and intergrader agreement was calculated using the κ-value. Patients with altered diagnoses and management attributable to UWFFA results were noted. RESULTS: A total of 93 eyes of 63 patients were included in the study. Of 93 eyes, 31 (33.3%) eyes had RVL on UWFFA, with 26 (28.0%) eyes and 5 (5.4%) eyes showing mild and moderate-severe RVL, respectively. Twenty-five (26.9%) eyes showed macular leakage, and 7 (7.5%) eyes showed optic disc leakage. The κ-values ranged from 0.85 - 0.87 indicating excellent intergrader agreement. Of the 31 eyes with RVL, the diagnosis was changed to anterior/intermediate uveitis for 9 (29.0%) eyes and to panuveitis for 4 (12.9%) eyes. Systemic treatment was escalated in 5 patients. CONCLUSION: Our results suggest that UWFFA imaging is useful in detecting subclinical posterior involvement in patients with anterior uveitis. Moreover, UWFFA results in altered diagnosis and treatment approaches in a portion of patients.

The Infectious Uveitis Treatment Algorithm Network (TITAN) Report 1-global current practice patterns for the management of Herpes Simplex Virus and Varicella Zoster Virus anterior uveitis.

AIMS: To present current expert practice patterns and to formulate a consensus for the management of HSV and VZV AU by uveitis specialists worldwide. METHODS: A two-round online modified Delphi survey with masking of the study team was conducted. Responses were collected from 76 international uveitis experts from 21 countries. Current practices in the diagnosis and treatment of HSV and VZV AU were identified. A working group (The Infectious Uveitis Treatment Algorithm Network [TITAN]) developed data into consensus guidelines. Consensus is defined as a particular response towards a specific question meeting ≥75% of agreement or IQR ≤ 1 when a Likert scale is used. RESULTS: Unilaterality, increased intraocular pressure (IOP), decreased corneal sensation and diffuse or sectoral iris atrophy are quite specific for HSV or VZV AU from consensus opinion. Sectoral iris atrophy is characteristic of HSV AU. Treatment initiation is highly variable, but most experts preferred valacyclovir owing to simpler dosing. Topical corticosteroids and beta-blockers should be used if necessary. Resolution of inflammation and normalisation of IOP are clinical endpoints. CONCLUSIONS: Consensus was reached on several aspects of diagnosis, choice of initial treatment, and treatment endpoints for HSV and VZV AU. Treatment duration and management of recurrences varied between experts.

The Infectious Uveitis Treatment Algorithm Network (TITAN) Report 2-global current practice patterns for the management of Cytomegalovirus anterior uveitis.

AIMS: To present current practice patterns in the diagnosis and management of Cytomegalovirus anterior uveitis (CMV AU) by uveitis experts worldwide. METHODS: A two-round modified Delphi survey with masking of the study team was performed. Based on experience and expertise, 100 international uveitis specialists from 21 countries were invited to participate in the survey. Variation in the diagnostic approaches and preferred management of CMV AU was captured using an online survey platform. RESULTS: Seventy-five experts completed both surveys. Fifty-five of the 75 experts (73.3%) would always perform diagnostic aqueous tap in suspected CMV AU cases. Consensus was achieved for starting topical antiviral treatment (85% of experts). About half of the experts (48%) would only commence systemic antiviral treatment for severe, prolonged, or atypical presentation. The preferred specific route was ganciclovir gel 0.15% for topical treatment (selected by 70% of experts) and oral valganciclovir for systemic treatment (78% of experts). The majority of experts (77%) would commence treatment with topical corticosteroid four times daily for one to two weeks along with antiviral coverage, with subsequent adjustment depending on the clinical response. Prednisolone acetate 1% was the drug of choice (opted by 70% of experts). Long-term maintenance treatment (up to 12 months) can be considered for chronic course of inflammation (88% of experts) and those with at least 2 episodes of CMV AU within a year (75-88% of experts). CONCLUSIONS: Preferred management practices for CMV AU vary widely. Further research is necessary to refine diagnosis and management and provide higher-level evidence.

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.

Treatment of Intermediate Uveitis-associated Retinal Vasoproliferative Tumors: A Case Series.

PURPOSE: To report the use of combination intravitreal pharmacotherapy using anti-vascular endothelial growth factor (VEGF) and short and long-term corticosteroid implants for the treatment of retinal vasoproliferative tumors (VPT) associated with intermediate uveitis. METHODS: Retrospective chart review of patients with VPT secondary to idiopathic intermediate uveitis that underwent combination intravitreal pharmacotherapy at a single center was performed. Multimodal imaging including ultrawide field color fundus photography, ultrawide field fluorescein angiography, and optical coherence tomography obtained before and after treatment were reviewed. RESULTS: Four eyes of 4 patients were treated with multiple injections of a combination of aflibercept, dexamethasone, and fluocinolone acetonide implants for VPT associated with intermediate uveitis. All 4 patients had improvement in visual acuity, intraocular inflammation, central macular thickness, and retinal vascular leakage, as well as regression of the VPT and reduction in lesion leakage on follow-up. CONCLUSION: Combination intravitreal anti-VEGF and corticosteroid implants may be a useful approach for the treatment of intermediate uveitis-associated VPTs and can lead to both functional and structural improvement.

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.

Refractory Candida dubliniensis Retinitis in an Immunocompetent Patient.

BACKGROUND: Fungal endophthalmitis is an intraocular infection that rarely develops in immunocompetent individuals. CASE: A 35-year-old healthy, immunocompetent male presented with a 1-week history of pain and redness in the left eye. Visual acuity was 20/50. Dilated fundus examination revealed focal chorioretinitis in the posterior pole with associated vitritis, suspicious for a fungal etiology. He was started empirically on oral voriconazole and valacyclovir. A comprehensive systemic workup returned negative. Inflammation worsened and a diagnostic vitrectomy was performed which revealed Candida dubliniensis. The dose of oral voriconazole was increased, and intravitreal voriconazole and amphotericin B injections were added for refractory disease. Treatment response was gauged by fungal pillar height on optical coherence tomography. Eight months of oral voriconazole and 68 intravitreal antifungal injections were required to achieve complete regression and a final visual acuity of 20/20. CONCLUSION: Candida dubliniensis endophthalmitis can affect immunocompetent individuals and require a prolonged treatment course.

Extensive Subretinal Fibrosis Associated with Pseudoxanthoma Elasticum.

PURPOSE: To report an unusual case of pseudoxanthoma elasticum (PXE) presenting with an inflammatory phenotype associated with atypical and rapidly progressive subretinal fibrosis. METHODS: Observational case report. RESULTS: A patient with a history of pseudoxanthoma elasticum presented with rapidly progressive subretinal fibrosis, particularly in the left eye, over the course of one year. The patient was noted at presentation to have intraocular inflammation, outer retinal attenuation, multifocal choroiditis-like lesions, and intraretinal fluid (in the absence of obvious clinical or angiographic signs of exudative CNVM). An ocular inflammatory phenotype was diagnosed, and the patient was treated with a combination of local steroids and systemic corticosteroids/immunomodulatory agents. After initiation of these agents, there was demonstrated functional and structural improvement, with partial outer retinal reconstitution, decreased intraretinal fluid, and lack of further progression of subretinal fibrosis. CONCLUSION: This report describes an inflammatory phenotype of PXE associated with severe and atypical subretinal fibrosis. This case expands upon the currently known spectrum of inflammatory phenotypes associated with PXE. Treatment with corticosteroids or immunomodulatory treatment should be considered in similar cases.

Histopathology and SARS-CoV-2 Cellular Localization in Eye Tissues of COVID-19 Autopsies.

Ophthalmic manifestations and tissue tropism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported in association with coronavirus disease 2019 (COVID-19), but the pathology and cellular localization of SARS-CoV-2 are not well characterized. The objective of this study was to evaluate macroscopic and microscopic changes and investigate cellular localization of SARS-CoV-2 across ocular tissues at autopsy. Ocular tissues were obtained from 25 patients with COVID-19 at autopsy. SARS-CoV-2 nucleocapsid gene RNA was previously quantified by droplet digital PCR from one eye. Herein, contralateral eyes from 21 patients were fixed in formalin and subject to histopathologic examination. Sections of the droplet digital PCR-positive eyes from four other patients were evaluated by in situ hybridization to determine the cellular localization of SARS-CoV-2 spike gene RNA. Histopathologic abnormalities, including cytoid bodies, vascular changes, and retinal edema, with minimal or no inflammation in ocular tissues were observed in all 21 cases evaluated. In situ hybridization localized SARS-CoV-2 RNA to neuronal cells of the retinal inner and outer layers, ganglion cells, corneal epithelia, scleral fibroblasts, and oligodendrocytes of the optic nerve. In conclusion, a range of common histopathologic alterations were identified within ocular tissue, and SARS-CoV-2 RNA was localized to multiple cell types. Further studies will be required to determine whether the alterations observed were caused by SARS-CoV-2 infection, the host immune response, and/or preexisting comorbidities.

Consensus-based recommendations for optical coherence tomography angiography reporting in uveitis.

BACKGROUND/AIMS: To establish a consensus in the nomenclature for reporting optical coherence tomography angiography (OCTA findings in uveitis. METHODS: The modified Delphi process consisted of two rounds of electronic questionnaires, followed by a face-to-face meeting conducted virtually. Twenty-one items were included for discussion. The three main areas of discussion were: wide field OCTA (WF-OCTA), nomenclature of OCTA findings and OCTA signal attenuation assessment and measurement. Seventeen specialists in uveitis and retinal imaging were selected by the executive committee to constitute the OCTA nomenclature in Uveitis Delphi Study Group. The study endpoint was defined by the degree of consensus for each question: 'strong consensus' was defined as >90% agreement, 'consensus' as 85%-90% and 'near consensus' as >80% but <85%. RESULTS: There was a strong consensus to apply the term 'wide field' to OCTA images measuring over 70° of field of view, to use the terms 'flow deficit' and 'non-detectable flow signal' to describe abnormal OCTA flow signal secondary to slow flow and to vessels displacement respectively, to use the terms 'loose' and 'dense' to describe the appearance of inflammatory choroidal neovascularisation, and to use the percentage of flow signal decrease to measure OCTA ischaemia with a threshold greater than or equal to 30% as a 'large area'. CONCLUSIONS: This study sets up consensus recommendations for reporting OCTA findings in uveitis by an expert panel, which may prove suitable for use in routine clinical care and clinical trials.

Antidrug Antibodies to Tumor Necrosis Factor α Inhibitors in Patients With Noninfectious Uveitis.

Importance: Tumor necrosis factor inhibitors (TNFis) can induce antidrug antibody (ADA) formation and loss of therapeutic response. However, the utility of ADA testing and the association between ADAs and treatment response in patients with noninfectious uveitis (NIU) is not well understood. Objective: To assess the frequency of ADAs and their association with drug levels and clinical response in patients with NIU treated with adalimumab or infliximab. Design, Setting, and Participants: This retrospective cross-sectional study included patients diagnosed with NIU who received adalimumab or infliximab and underwent testing for serum drug level and ADAs at the National Eye Institute from September 2017 to July 2021. Exposures: Serum drug level testing with reflex testing for ADA levels was performed. Main Outcomes and Measures: The main outcome was the association between drug levels and ADAs, clinical response, and concurrent antimetabolite use in patients treated with TNFis for NIU. Results: Of 54 patients included in the study, 42 received adalimumab (mean [SD] age, 43.6 [19.6] years; 25 [59.5%] female) and 12 received infliximab (mean [SD] age, 42.7 [20.4] years; 7 [58.3%] male). In the adalimumab group, mean (SD) drug level was 9.72 (6.82) µg/mL, mean (SD) ADA level was 84.2 (172.9) arbitrary units/mL, and ADA frequency was 35.7% (15 of 42 patients). Mean drug level was lower in those with ADAs compared with those without ADAs (mean [SD], 2.8 [2.6] µg/mL vs 13.6 [5.2] µg/mL; difference: 10.8 µg/mL; 95% CI, 8.3-13.2 µg/mL; P < .001). There was a higher mean drug level with concurrent antimetabolite use compared with monotherapy (mean [SD], 11.0 [7.3] µg/mL vs 6.8 [4.5] µg/mL; difference: -4.2 µg/mL; 95% CI, -8.7 to 0.2 µg/mL; P = .06). Multivariable modeling showed that a 1-arbitrary unit increase in ADAs was associated with a -0.02 µg/mL (95% CI, -0.01 to -0.34 µg/mL) difference in mean drug level (P < .001). Favorable clinical response was associated with a threshold drug level above 2.7 µg/mL or an antibody level below 15.2 µg/mL. The mean (SD) drug level in the infliximab group was 27.02 (18.15) µg/mL, and no ADAs were detected. Conclusions and Relevance: In this study, 35.7% of adalimumab-treated patients with NIU had ADAs. The presence of ADAs was associated with lower drug levels, and higher ADA levels were associated with increased risk of TNFi treatment failure. Although limited by the retrospective design, our results suggest that therapeutic drug monitoring may be considered among patients experiencing therapy failure to help exclude ADAs as a potential cause of treatment failure.

Ophthalmic Manifestations of ROSAH (Retinal Dystrophy, Optic Nerve Edema, Splenomegaly, Anhidrosis, and Headache) Syndrome, an Inherited NF κB-Mediated Autoinflammatory Disease with Retinal Dystrophy.

PURPOSE: We aimed to characterize the ocular phenotype of patients with ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and headache) syndrome and their response to therapy. DESIGN: Single-center observational case study. PARTICIPANTS: Eleven patients with a diagnosis of ROSAH syndrome and mutation in ALPK1 were included. METHODS: Patients with molecularly confirmed ROSAH syndrome underwent ophthalmic evaluation, including visual acuity testing, slit-lamp and dilated examinations, color fundus and autofluorescence imaging, fluorescein angiography, OCT, and electrophysiologic testing. MAIN OUTCOME MEASURES: Visual acuity, electrophysiology, fluorescein angiography, and OCT findings. RESULTS: Eleven individuals (6 female and 5 male patients) from 7 families ranging in age from 7.3 to 60.2 years at the time of the initial evaluation were included in this study. Seven patients were followed up for a mean of 2.6 years (range, 0.33-5.0 years). Best-corrected visual acuity at baseline ranged from 20/16 to no light perception. Variable signs or sequelae of intraocular inflammation were observed in 9 patients, including keratic precipitates, band keratopathy, trace to 2+ anterior chamber cells, cystoid macular edema, and retinal vasculitis on fluorescein angiography. Ten patients were observed to show optic disc elevation and demonstrated peripapillary thickening on OCT. Seven patients showed retinal degeneration consistent with a cone-rod dystrophy, with atrophy tending to involve the posterior pole and extending peripherally. One patient with normal electroretinography findings and visual evoked potential was found to have decreased Arden ratio on electro-oculography. CONCLUSIONS: Leveraging insights from the largest single-center ROSAH cohort described to date, this study identified 3 main factors as contributing to changes in visual function of patients with ROSAH syndrome: optic nerve involvement; intraocular inflammation, including cystoid macular edema; and retinal degeneration. More work is needed to determine how to arrest the progressive vision loss associated with ROSAH syndrome.

Ocular symptoms in COVID-19 infection: a survey study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) systemic symptoms and sequelae have been studied extensively, but less is known about the characterization, duration, and long-term sequelae of ocular symptoms associated with COVID-19 infection. The purpose of this study was to analyze the frequency, spectrum, and duration of ocular symptoms in participants with COVID-19 infection treated in inpatient and outpatient settings. METHODS: A retrospective electronic survey was distributed to NIH employees and the public who reported testing positive for SARS-CoV-2. The anonymous survey collected information on demographics, past ocular history, systemic COVID-19 symptoms, and ocular symptoms. RESULTS: A total of 229 (21.9% male and 78.1% female, mean age 42.5 ± 13.9) survey responses were included. Ocular symptoms were reported by 165 participants with a mean of 2.31 ± 2.42 symptoms. The most commonly reported ocular symptoms were light sensitivity (31.0%), itchy eyes (24.9%), tearing (24.9%), eye redness (24.5%), and eye pain (24.5%). Participants with ocular symptoms had a higher number of systemic symptoms compared to participants without ocular symptoms (mean 9.17 ± 4.19 vs 6.22 ± 3.63; OR: 1.21; 95% CI: 1.11 - 1.32; p < 0.001). Ocular symptoms were more common in those who reported a past ocular history compared to those who did not (81.8% vs 67.1%; OR: 2.17; 95% CI: 1.08 - 4.37; p = 0.03). Additionally, the onset of ocular symptoms occurred most frequently at the same time as systemic symptoms (47.5%), and 21.8% reported symptoms lasting ≥ 14 days. CONCLUSIONS: Ocular surface-related symptoms are the most frequent ocular manifestations, and systemic disease severity is associated with the presence of ocular symptoms. Additionally, our results show that ocular symptoms can persist post-COVID-19 infection. Further work is needed to better understand ocular symptoms in COVID-19 and long-term sequelae.

A Network of Serum Proteins Predict the Need for Systemic Immunomodulatory Therapy at Diagnosis in Noninfectious Uveitis.

Purpose: Early identification of patients with noninfectious uveitis requiring steroid-sparing immunomodulatory therapy (IMT) is currently lacking in objective molecular biomarkers. We evaluated the proteomic signature of patients at the onset of disease and associated proteomic clusters with the need for IMT during the course of the disease. Design: Multicenter cohort study. Participants: Two hundred thirty treatment-free patients with active noninfectious uveitis. Methods: We used aptamer-based proteomics (n = 1305 proteins) and a bioinformatic pipeline as a molecular stratification tool to define the serum protein network of a Dutch discovery cohort (n = 78) of patients and healthy control participants and independently validated our results in another Dutch cohort (n = 111) and a United States cohort (n = 67). Multivariate Cox analysis was used to assess the relationship between the protein network and IMT use. Main Outcome Measures: Serum protein levels and use of IMT. Results: Network-based analyses revealed a tightly coexpressed serum cluster (n = 85 proteins) whose concentration was consistently low in healthy control participants (n = 26), but varied among patients with noninfectious uveitis (n = 52). Patients with high levels of the serum cluster at disease onset showed a significantly increased need for IMT during follow-up, independent of anatomic location of uveitis (hazard ratio, 3.42; 95% confidence interval, 1.22-9.5; P = 0.019). The enrichment of neutrophil-associated proteins in the protein cluster led to our finding that the neutrophil count could serve as a clinical proxy for this proteomic signature (correlation: r = 0.57, P = 0.006). In an independent Dutch cohort (n = 111), we confirmed that patients with relatively high neutrophil count at diagnosis (> 5.2 × 109/L) had a significantly increased chance of requiring IMT during follow-up (hazard ratio, 3.2; 95% confidence interval, 1.5-6.8; P = 0.002). We validated these findings in a third cohort of 67 United States patients. Conclusions: A serum protein signature correlating with neutrophil levels was highly predictive for IMT use in noninfectious uveitis. We developed a routinely available tool that may serve as a novel objective biomarker to aid in clinical decision-making for noninfectious uveitis.
