| Title | Comparative clinical patterns and outcomes of non-occlusive and occlusive retinal vasculitis |
| 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 = .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 = .006 and
p ≤ 10–3, respectively), and retinal hemorrhages (p = .048) and optic atrophy (p = .040) in the ORV group. |
| Conclusion | Occlusive and non-occlusive RV have distinctive clinical and etiological profile. |
