Figure 3.

Two pairs of poor quality (A and C) and good quality (B and D) OCTA en-face images (A1-D1, on the top row) and their respective en-face heatmaps (A2-D2, on the bottom row) are shown. The first pair shows a poor quality macular image with a large shadow artifact affecting the left upper quadrant (A1) and its corresponding influence on vessel density heatmap (A2). The corresponding good quality images are shown in B1 (en-face angiogram) and B2 (en-face heatmap) after image recapture with artifact removal that resulted in a change in macular superficial vessel density (SVD) from 41.6% to 48.9%. Similarly, another sample of a macular image with mixed defocus and eye movement artifacts are shown in C1 and C2 with their corresponding good quality images shown in D1 and D2. Image recapture with the intent to remove the artifacts resulted in a change in SVD from 35.8% to 45.7%.
