Figure 1.

The clinical images and OCTA images with different field of views (FOVs) of a 33-year-old man (patient #1) with a diagnosis of non-high risk PDR in his right eye. (A) 50-degree color fundus image; (B) 50-degree early phase of FA image; (C,D,E) typical OCTA color-coded images with a FOV of 3×3, 6×6, and 12×12 mm² scans, respectively; (F) the ultra-wide OCTA color-coded image with a FOV of approximately 100 degrees. Red indicates superficial retinal layer (SRL); Green indicates deep retinal layer (DRL); Purple indicates the vitreous retinal layer (VRL) to demonstrate neovascularization consistent with PDR. The FOVs of each image are listed in the table.
