Purpose: To describe the demographics and clinical characteristics of anterior scleritis associated with uveitis in a referral center in Tunisia. Methods: The charts of twenty patients (20 eyes) diagnosed with sclero‐uveitis at Fattouma Bourguiba University Hospital, Monastir, Tunisia, presented between January 2015 and April 2022, were retrospectively reviewed. Detailed ophthalmic examination and fundus photography were performed in all patients. Mean follow‐up period was 28.4 months. Patients with keratitis or posterior scleritis were excluded. Results: There were eight women and 12 males patients with a mean age of 34.8 years. All patients presented with ocular pain. Mean initial best‐corrected visual acuity (BCVA) was 20/80 (range, 20/2000–20/25).There was an associated anterior uveitis in 80% of cases and panuveitis in 20%. Clinical findings at presentation included nodular scleritis in five eyes (25%) and scleromalacia perforans in four eyes (20%). Idiopathic sclero‐uveitis accounted for almost 55%. Identified causes of sclerouveitis included rheumatoid arthritis in four eyes (20%), tuberculosis in three eyes (15%), granulomatosis with polyangiitis in two eyes (10%), sarcoidosis in one eye (5%) and then one case after mRNA 1273 vaccine (5%). Ocular complications included pupillary seclusion in 25% of cases and vision loss in 10% of patients. Mean final BCVA was 20/100 (range, 20/4000–20/32). Treatment modalities of non‐infectious scleritis included indomethacine in 14 patients (82.3%), systemic corticosteroid in seven patients (41.1%) and immunosuppressant or biological agent in five patients (29.4%). Conclusions: Our results provide useful information about the patterns and etiologies of sclerouveitis. The leading causes of sclerouveitis include mainly rheumatoid arthritis and tuberculosis. An infectious cause should be always ruled out. [ABSTRACT FROM AUTHOR]

Purpose: To compare clinical profile and visual outcomes of occlusive versus non‐occlusive retinal vasculitis (RV). Methods: A retrospective comparative study. Results: 284 patients were enrolled, including 124 patients with occlusive RV (ORV) and 160 patients with nonocclusive RV (NORV). Patients with ORV were older (p ≤ 10‐3), predominantly male (p ≤ 10‐3), with less bilateral involvement (31.5% vs. 53.4%; p ≤ 10‐3). Infectious RV was more frequently diagnosed in the ORV group than in the NORV group (48.8% vs. 32.9%, p = 0.006). Behçet disease and ocular tuberculosis were the leading causes of ORV. Idiopathic RV, Behçet disease, and sarcoidosis were the most common causes of NORV. Independent predictive factors of poor visual outcome were worse baseline visual acuity in both groups (p = 0.006 and p ≤ 10‐3, respectively), and retinal haemorrhages (p = 0.048) and optic atrophy (p = 0.040) in the ORV group. Conclusions: Occlusive and non‐occlusive RV have distinctive clinical and etiological profile. References 1. Agarwal A, Karkhur S, Aggarwal K, Invernizzi A, Singh R, Dogra MR, et al.
