PurposeTo evaluate the retinal vascular plexus and choriocapillaris structures in patients with non-ocular Behcet's disease (BD) using optical coherence tomography angiography (OCTA).MethodsThe study included 42 eyes of non-ocular BD patients (study group) and 40 eyes of 20 healthy subjects (control group). Flow area (mm(2)), mean vascular density (VD) (%) and foveal avascular zone (FAZ) (mm(2)) were measured using OCTA (Optovue Inc., Fremont, CA, USA). Subfoveal choroidal thickness (CT) (mu m) and central macular thickness (CMT) (mu m) measurements were also performed.ResultsThe mean superficial capillary plexus, deep capillary plexus and choriocapillaris flow area values were found to be significantly lower in the study group than in the control group (p
