Research Abstract

Purpose:

The purpose of the study was to describe macular vascular changes in patients with Behcet's disease (BD) using optical coherence tomography angiography (OCTA) and to compare these findings with those of fluorescein angiography (FA).

Patients and Methods:

This was a comparative, cross-sectional study. Patients with BD presenting with active uveitis were evaluated using FA and swept-source OCTA. 3 mm× 3 mm and 6 mm× 6 mm en-face images were reviewed and analyzed. Foveal avascular zone (FAZ) areas and vessel densities were also reported.

Results:

Twenty-five patients (39 eyes) were included. OCTA was superior to FA in showing macular microvascular changes which include areas of retinal capillary hypoperfusion, perifoveal capillary plexuses disruption and capillary abnormalities (including rarefied, dilated, or shunting vessels) were observed more frequently using OCTA than FA …
