Aims: To compare effectiveness of subconjunctival triamcinolone acetonide injections and intravitreal injections of dexamethasone 700 µg implants in reducing central macular thickness (CMT) in uveitic and postoperative macular oedema (ME)., Methods: We conducted an open-label, French multicentre randomised comparative trial with a logarithmic CMT non-inferiority margin set at 0.06. Patients were adults with non-infectious inflammatory ME, without any contraindication to the treatments. They were randomised 1:1 to receive either triamcinolone or dexamethasone. The primary endpoint was the difference in CMT among treated eyes between baseline and 2 months, measured with spectral-domain optical coherence tomography. Secondary outcomes included visual acuity, laser flare, vitreous haze, duration of action, tolerance to injections and adverse events., Results: Between January 2016 and January 2020, 106 patients were enrolled (54 in the triamcinolone group and 52 in the dexamethasone group). Subconjunctival triamcinolone injections seemed to be non-inferior to intravitreal dexamethasone injections, especially at month 3 (and nearly at month 1). Nevertheless, we could not demonstrate it, with a treatment effect at month 2 of 0.05 (0.01 ; 0.09) (p value=0.001). This was corroborated by post hoc analyses in the postoperative subgroup, for whom the non-inferiority was nearly demonstrated at month 2 with a treatment effect of 0.02 (-0.03 ; 0.08) (p=0.37). There was no significant difference in the occurrence of adverse effects., Conclusion: We could not demonstrate the non-inferiority of triamcinolone injections at month 2. Nevertheless, they showed some efficacity, particularly in treating postoperative ME, being as safe as dexamethasone injections, without any loss of chance if a therapeutic switch is necessary., Competing Interests: Competing interests: M-AV: data safety monitoring board member in Comité de Protection des Personnes—Ouest IV since september 2022.

Purpose: To describe a patient with hypertensive herpetic uveitis complicated by arterial retinal occlusions and a decompression retinopathy revealing a sickle cell trait., Study Design: Case report., Results: A 24-year-old African man presented with a hypertensive herpetic keratouveitis. A brutal lowering of the intraocular pressure (IOP) by systemic acetazolamide resulted in a ocular decompression retinopathy and multiple arterial occlusions involving the macular and the mid-periphery retina. A hemoglobin electrophoresis revealed a sickle cell trait., Conclusion: Under rare circumstances, vaso occlusive events can occur in patients with a sickle cell trait. We identified high IOP and acetazolamide to be responsible of an increased blood viscosity and a reduction of the vessels' caliber, resulting in sickling and arterial retinal occlusions. We recommend a thorough anamnesis and a sickle cell screening for patients of African or Mediterranean descent with acute elevated IOP, especially if they have to be treated with carbonic anhydrase inhibitors.

Introduction: Paediatric granulomatous uveitis (PGU) is rare. In addition, lack of awareness often leads to delayed diagnosis and poor visual outcome. Identifying the underlying cause and deciding how best to treat each patient is challenging., Objectives: To evaluate the demographics, aetiologies, complications, treatments, and visual prognosis of paediatric non-infectious granulomatous uveitis., Methods: Retrospective chart review of non-infectious PGU occurring in children before the age of 16 years recruited from the Paediatric Rheumatology Unit, Bicêtre Hospital, France, from 2001 to 2023., Results: We included 50 patients with 90 affected eyes: 29 with idiopathic uveitis, 15 with sarcoidosis, 5 with juvenile idiopathic arthritis, and one with Vogt-Koyanagi-Harada disease. Median age at diagnosis was 9.8 years (range 7.2-12.5). The sex-ratio M/F was 0.52. The most common features of PGU were: panuveitis (56%), bilateral (84%), and chronic (84%). Sarcoidosis was the most frequent diagnosis after idiopathic disease, particularly in the presence of lymphopenia and hypergammaglobulinemia. Uveomeningitis was present in 12% of cases. Upon diagnosis, ocular complications were present in 68 of 90 eyes (76%) particularly in cases of panuveitis. The most commonly used treatments were systemic corticosteroids (72%) and methotrexate (80%). Twenty-three percent of eyes were in remission at last follow-up, 68% were inactive and 4% remained active. The median duration of follow-up was 5.8 years., Conclusion: We report the largest cohort of PGU. PGU were mostly idiopathic and had a high rate of complications. Sarcoid and idiopathic panuveitis are serious illnesses in which disease-modifying therapy should be initiated at diagnosis to improve management., (© The Author(s) 2024.

Objective: To examine whether the COVID-19 pandemic was associated with an increased incidence of uveitis in children., Study Design: We performed a time-series analysis of patient records from a national, hospital-based, French surveillance system. All children hospitalized for uveitis in France between January 2012 and March 2022 were included. The incidence of newly diagnosed uveitis per 100 000 children per trimester in France was analyzed by a quasi-Poisson regression. A cohort of children diagnosed with uveitis at Robert-Debré Hospital was used to compare the characteristics of uveitis after and before the onset of the pandemic., Results: During the study period, 2492 children were hospitalized for uveitis in France. The COVID-19 pandemic, which started in March 2020, was associated with a significant increase in the occurrence of uveitis (estimated cumulative change, 44.9%; 95% CI 11.4-78.4; P < .001). The increase in the incidence of pediatric uveitis started in October 2020, while the national immunization program targeting children aged less than 18 years began in June 2021. This increase involved all forms of uveitis, regardless of location, and clincial characteristics were similar to those diagnosed before the pandemic., Conclusions: Our study evidenced a significant increase in the incidence of pediatric uveitis following the COVID-19 pandemic. This increase occurred 6 months before the implementation of the national COVID-19 vaccination program for children, suggesting that the resurgence of this rare disease is independent of COVID-19 vaccination., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2023 The Author(s).

Purpose: To report two cases of multiple evanescent white dot syndrome (MEWDS) following COVID-19 vaccination with the BNT162b2 mRNA vaccine., Methods: Two case reports. Case-1: A 40-yo Caucasian male, complained of blurred and decrease of vision in his left eye (OS) one week after the first dose of the BNT162b2 mRNA SARS-CoV-2 vaccine. Funduscopic examination OS showed multiple granular white dots with an aspect of foveal granularity. Case-2: A 23-yo woman also presented with defective and decrease of vision OS. She received her first dose of the BNT162b2 mRNA SARS-CoV-2 vaccine ten days before. Dilated fundus examination OS showed altered macular reflex with an aspect of foveal granularity., Results: Multimodal imaging showed features of MEWDS in both cases. The anomalies found resolved spontaneously after 6 weeks., Conclusion: Inflammation and immune dysregulation induced by COVID-19 mRNA vaccine or its adjuvants could be involved in ocular adverse effects.

Objective: To highlight the safety and efficacy of Tumor Necrosis Factor inhibitors (anti-TNF) in inflammatory choroidal neovascularization (CNV) in the pediatric population., Design: Retrospective case series., Participants: Three patients, < 16 years old with uveitic inflammatory CNV., Methods: Patients received systemic steroids, methotrexate (MTX), intravitreal (IVT) injections of bevacizumab, and anti-TNF (infliximab or adalimumab) in case of refractory leakage., Results: Five eyes of three pediatric patients (mean age 6 years old) presenting with CNV and put on anti-TNF were followed up for a minimum of 32 months. Four out of five eyes had improved vision, reduced fluid on clinical exam and macular spectral-domain optical coherence tomography (SD-OCT), and cessation of leakage on fundus fluorescein angiography (FFA) after introduction of anti-TNF agents. Two patients developed minor psoriasis treated topically., Conclusion: Anti-TNF agents showed efficacy and safety in a sustainable leakage control of inflammatory pediatric CNV along with improvement in vision.

To suggest a unique missense variant candidate based on long-term ophthalmological changes and associated systemic signs described in five patients from two unrelated families affected by an autosomal dominant multi-systemic disorder including Retinal dystrophy, Optic nerve oedema, Splenomegaly, Anhidrosis and migraine Headaches, called ROSAH syndrome, related to a unique missense variant in ALPK1 gene. Observational longitudinal follow-up study of unrelated families. Clinical analysis of ophthalmological and systemic examinations was performed, followed by genetic analysis, including targeted Next Generation Sequencing (NGS) and Whole-Genome Sequencing (WGS). The ophthalmological phenotype showed extensive optic nerve swelling associated with early macular oedema and vascular leakage. The main associated systemic manifestations were recurrent fever, splenomegaly, anhidrosis, mild cytopenia, anicocytosis and hypersegmented polynuclear cells. WGS, shortened in the second family by the gene candidate suggestion, revealed in all patients the heterozygous missense variant c.710C>T; p.(Thr237Met) in ALPK1. The primary morbidity in ROSAH syndrome in this cohort appeared ophthalmological. Comprehensive, detailed phenotype changes aided by the advancement in genetic testing could allow an early genetic diagnosis of ROSAH syndrome and targeted treatment. The unique missense variant may be suggested as a target of gene correction therapy., (© 2022 The Authors. Clinical Genetics published by John Wiley & Sons Ltd.)

Purpose: To compare the relapse rate of sight-threatening noninfectious uveitis (NIU) in patients treated with infliximab (IFX) or adalimumab (ADA)., Design: Observational retrospective multicenter study., Methods: A total of 330 patients (median age, 36 years; interquartile range, 27-54), 45.2% men) with sight-threatening NIU (ie, retinal vasculitis and/or macular edema) treated with anti-tumor necrosis factor [TNF]-α agents (IFX intravenously at 5 mg/kg at weeks 0, 2, 6, and every 4 to 6 weeks or ADA subcutaneously at 80 mg, then 40 mg every 2 weeks). Data were obtained retrospectively from patients' medical records. Main outcome measures were relapse rate, complete response of NIU, corticosteroid sparing effect, and safety., Results: Main etiologies of uveitis included Behçet disease (27%), idiopathic juvenile arthritis (5.8%), and sarcoidosis (5.5%). The estimated relapse rate at 6 months after introduction of biological agents was 13% (95% CI = 0.009-0.16). IFX was associated with less relapse risk than ADA (hazard ratio [HR] = 0.52, 95% CI = 0.36- 0.77, P = .001). ADA and IFX were comparable in terms of complete response rate of NIU as well as corticosteroid-sparing effect. Behçet disease was associated with higher odds of complete response (HR = 2.04, 95% CI = 1.16 -3.60, P = .01] and lower relapse rate (HR = 0.53, 95% CI = 0.33-0.85, P = .009) than other causes of NIU with anti-TNF-α agents., Conclusions: In sight-threatening NIU, IFX seems to be associated with a lower relapse rate than ADA., (Copyright © 2022 Elsevier Inc.
