Figure 3: Proposed mechanism for the appearance of spotted grid pattern of hypoperfusion on vessel density map. (a) Raw optical coherence tomography angiography (OCTA) scan obtained in the y-axis. (b) Raw OCTA scan obtained in the x-axis. (c) Resultant vessel density map demonstrating spotted grid pattern of hypoperfusions. Dashed lines represent positions of hypointense flow signal bands. (d) Corresponding en face structural projection showing absence of any artifacts.
