Long-term progression of retinal vasculitis in Behçet patients using a fluorescein angiography scoring system

Background: To evaluate the long-time progression of retinal vasculitis in Behçet patients using the fluorescein angiography (FA) scoring system. Methods: Retrospective study was conducted for 71 eyes of 43 patients who met the study criteria. All patients completed at least 2 years of follow-up. FA was taken during the periods of active retinal vasculitis and the quiescent phase, and analyzed using a FA scoring system. Among nine categories, the four most prevalent FA signs were evaluated: optic disc hyperfluorescence (score 0-3), macular edema (score 0-4), retinal vascular staining and/or leakage (score 0-7), and capillary leakage (score 0-10). Results: Mean number of total active inflammations was 2.6±1.5 times during mean 55.0±20.0 months. Mean scores at the first active inflammation were 1.8±1.0 for optic disc hyperfluorescence, 2.4±1.0 for macular edema, 5.3±2.1 for retinal vascular staining and/or leakage, and 5.8±3.2 for capillary leakage. Mean total FA score was 17.4±6.8. Mean scores at the first quiescent phase were 0.6±0.4 for optic disc hyperfluorescence, 1.1±1.2 for macular edema, 3.8±1.9 for retinal vascular staining and/or leakage, and 3.5±3.5 for capillary leakage. Mean total FA score was 9.1±5.0. Mean scores for each active inflammation and quiescent phase were not significantly changed, and mean FA scores were significantly reduced in quiescent phase (P=0.003 for optic disc hyperfluorescence, P=0.005 for macular leakage, P=0.010 for retinal vascular staining and/or leakage, P=0.008 for capillary leakage, and P=0.018 for total FA score; paired t-test). Conclusions: Retinal vasculitis of Behçet patients did not significantly progress during long-term follow-up.
