Figure 2: Optical coherence tomography angiography (OCTA) and enface OCT images of case 1:(a-d) Initial visit: Vascular changes noted at (a) superficial retina, (b) deep retinal and (c) choriocapillary level. The dark areas are mostly due to motion and projection artefacts as seen on (d) the outer retinal enface OCT. At 3 years follow-up: perfusion defectscan be noted at (e) superficial, and (f) deep retinal level, with preservation of the (g) choriocapillaris. (h) shows enface OCT section. (i and j) Follow-up OCTA superficial retinal vascular density maps showing reduced scores |
