Figure 2.

A 4.5 × 4.5 mm OCTA scan (336 × 336 pixels) was performed in the nasal quadrant of the corneal limbus (A). The region of interest is defined as 150 × 150 pixels (B) perpendicular to the corneal limbus at 9 o'clock. A binary image was obtained from adaptive threshold binarization and morphologic process to measure vessel density (C). The skeletonization was performed to obtain the total vessel length (D).
