OCT-angiography (OCT-A) was found to be more successful than fluorescein angiography (FA) in evaluating perifoveal microvascular changes in patients with active Behçet disease. In the study of Khairallah et al. including 44 eyes with active Behçet’s disease, it was shown that OCT-A is superior to fluorescein angiography (FA) in evaluating the perifoveal microvascular structure. Perifoveal microvascular structure was observed significantly more clearly in OCT-A than FA. In addition impairment of the perifoveal capillary network, retinal capillary nonperfusion areas and perifoveal capillary anomalies were detected more frequently with OCT-A. It was stressed that the foveal avascular area was significantly larger in the group with Behçet’s uveitis compared to the control group, and that OCT-A was superior to FA in evaluating the foveal vascular structure in Behçet’s disease.
