In the original publication, the yellow circles in Figs. 2a, 2b, 3a and 3b are placed incorrectly. The corrected Figs. 2a, b and 3a, b are given in this Erratum.

A 63-year-old man with proliferative diabetic retinopathy of the right eye. a The fundus photograph shows a red punctate spot thought to be a microaneurysm (MA; yellow circle). b The MA is seen in a 3 × 3-mm square of an en face image (yellow circle). The MA was confirmed in optical coherence tomography (OCT) B-scan images with the c vertical and d horizontal sliders aligned. A ring-shape, thought to be the MA, can be seen. The MA lumen was open and cystoid macular edema was observed in the vicinity. e A comma-like finding was observed in a 3 × 3-mm square OCT angiography (OCTA) en face image (deep plexus). This was defined as a comma-like-type MA. f The yellow circle shows hyperfluorescence in a fluorescence angiographic (FA) image (1 minute and 6 seconds) matching the OCTA en face image. g The yellow circle shows hyperfluorescence in an indocyanine green angiographic (IA) image (2 minutes and 41 seconds) matching the OCTA en face image

A 64-year-old woman with moderate nonproliferative diabetic retinopathy of the left eye. a A fundus photograph shows a red punctate spot thought to be a microaneurysm (MA; yellow circle). b The MA is seen in a 3 × 3-mm square of an en face image (yellow circle). The MA was confirmed in optical coherence tomography (OCT) B-scan images with the c vertical and d horizontal sliders aligned. A ring-shape, thought to be the MA, can be seen. The MA lumen was open and cystoid macular edema was observed in the vicinity. e An aneurysm could not be confirmed in a 3 × 3-mm square OCT angiography (OCTA) en face image (deep plexus). This was defined as an absent-type MA. f The yellow circle shows hyperfluorescence in a fluorescein angiographic (FA) image (38 seconds) matching the OCTA en face image. g The yellow circle shows hyperfluorescence in an indocyanine green angiographic (IA) image (21 seconds) matching the OCTA en face image
