Assessment of Vascular Change Using Swept-Source Optical Coherence Tomography Angiography: A New Theory Explains Central Visual Loss in Behcet’s Disease

Figure 1

Multimodality imaging in the Behcet uveitis eye with 20/20 visual acuity complain about central visual loss. (a) Fundus photography shows generalized retinal artery attenuation. (b) Fluorescein angiography (FA) demonstrates hypoperfusion area measured in the early phase of FA (yellow area). (c) Superficial capillary plexus (SCP) slap in the optical coherence tomography angiography (OCTA) demonstrates hypoperfusion area in SCP (green area). (d) Deep capillary plexus (DCP) slap in the OCTA demonstrates hypoperfusion area in DCP (green area), and segmentation defect/artifact (red area) mimics hypoperfusion area caused by intraretinal cystoid change (arrow head) which corresponded with (e) structural en-face image and (f) B-scan OCT image. (e) Structural en-face image of DCP slap demonstrates intraretinal cystoid change.
