These cases showed no significant clinical signs of diabetic retinopathy on colour fundus photos. a OCTA of a normal fundus of a diabetic eye without clinical signs. b A nonperfusion area (NPA) (asterisk) is shown in the superior nasal quadrant. c Both a NPA (asterisk) and capillary tortuosity (arrows) could be detected in the inferior nasal quadrant
