Typical case 1. Color fundus photography (CFP) (A) and fluorescein angiography (FA) (B) were performed before treatment and showed high-risk PDR in the left eye. CFP examinations showed NV, which was confirmed by FFA (B, arrow). OCT examinations showed macular edema (C). CFP and FA examinations after a follow-up of 12 months showed that the retina had laser shots. No NV was found via either CFP or FA examinations (D, E). OCT examinations of the left eye showed the transformation from edema to full recovery of the macula (F).

Typical case 2. The patient was diagnosed with high-risk PDR in the left eye and treated with PRP. Color fundus photography (CFP) (A) and fluorescein angiography (FA) (B) before treatment showed high-risk PDR in the left eye. The CFP examinations showed vitreous hemorrhage (blue arrow, A), and the FFA examinations showed NV [yellow arrow, (B)]. OCT showed that no macular edema was present (C). CFP and FA examinations after a follow-up of 12 months showed that the retina had laser shots. The CFP examinations showed that the area of the vitreous was smaller (blue arrow, D), but the FA examinations showed NV leakage (yellow arrow, E). OCT examinations of the left eye showed that macular edema was absent (F).
