Purpose:
To identify significant fluorescein angiographic (FA) characteristics associated with visual acuity (VA) in Behçet retinal vasculitis.
Materials And Methods:
Retrospective review of 86 eyes of 48 patients (age: 35.6±10.2 years) with Behçet retinal vasculitis were performed. VA and FA findings as well as correlation between them were assessed.
Results:
The mean initial VA of eyes with posterior pole-involved vasculitis (63 eyes; 73.3%) was significantly worse than that of those with peripheral vasculitis (23 eye; 26.7%) (logarithm of the minimum angle of resolution VA: 0.554±0.572 vs. 0.078±0.148; p<0.0001). Subgroup analysis revealed a more severe and diffuse pattern of vascular leakage in posterior pole-involved vasculitis compared to peripheral vasculitis (p<0.0001). Retinal vascular leakage (β=0.345; p<0.0001), optic disc hyperfluorescence (β=0.147; p=0.032), and macular leakage (β=0.107; p=0.047) were significantly associated with worse initial VA. During the follow up (mean: 33.3±17.9 months), the change of leakage showed no significant correlation with change of VA in posterior pole-involved vasculitis (τ=0.199, p=0.092).
Conclusion:
Posterior pole involvement, the degree of retinal vascular leakage, optic disc hyperfluorescence, and macular leakage are significantly associated with VA in Behçet retinal vasculitis.
