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.

Purpose: To compare clinical findings and visual outcomes of vitreous haemorrhage (VH) associated with inflammatory ocular conditions between children and adults patients. Methods: Retrospective study including 46 patients (56 eyes) diagnosed with VH associated with inflammatory ocular conditions in Department of ophthalmology, Fattouma Bourguiba university hospital, Tunisia. Demographics, clinical findings, etiologies, treatment modalities, and visual outcomes were compared between adults and children. Mean follow‐up period was 18 months. Results: There were 10 children (12 eyes) and 36 adults (44 eyes) patients. Mean age was 9.5 years in the children group (six males and four females) and 35 years in the adult group (26 males and 10 females). Comparative study showed that VH in the paediatric group was associated with a significantly lower presenting visual acuity, more frequently vitritis and fern‐like capillaritis, whereas VH in the adult group were more associated with vascular sheathing and retinal haemorrhages. The main mechanism of bleeding was inflammatory optic disc neovessels (NV) in the children group (66.6%, p ≤ 0.001) and ischemic posterior segment NV in the adult group (81.8%, p ≤ 0.001). Idiopathic intermediate uveitis (40%) was the leading cause of VH in the children group. However, tuberculosis (41.7%), Behçet's (19.4%) disease and sarcoidosis (11.1%) were the most common etiologies in the adult group. The mean final visual acuity was significantly higher in the paediatric group (20/25) than the adult group (20/50) (p = 0.045). Conclusions: Inflammatory VH has a distinctive clinical and etiological profile between children and adults. References 1. Agarwal A, Karkhur S, Aggarwal K, Invernizzi A, Singh R, Dogra MR, et al.
