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.
