Abstract Details


To measure the vascular density (VD) and foveal avascular zone (FAZ) area in patients with Behcet's disease (BD) by using optical coherence tomography angiography (OCT-A)




VD and FAZ thickness in the deep and superficial retinal vascular networks were measured in all eyes.


Thirty BD and 31 control eyes were included in this study. The mean overall VD measured in the entire scan was lower in BD compared to control group in both the superficial (49.52±6.54vs53.57±2.87%,respectively; p=0.003) and deep (53.44±7.44vs58.41±3.01%, respectively; p= 0.002) area. The FAZ in BD patient was significantly increased at the level of the superficial (0,52±0.67vs 0.28±0,1mm2, respectively; p= 0.05) and deep (0.91±1.25vs0.39±0.14mm2,respectively; p= 0.024) area when compared to the control groups.


In the eyes of the patients with BD, OCT-A showed decreased VD in both the superficial and deep vascular
