Report of a case with retinal neovascularization developing in the setting of diabetic retinopathy despite complete posterior vitreous detachment (PVD).
A 76-year-old man had had type II diabetes mellitus for more than 30 years. Weiss' ring was detected by direct and indirect ophthalmoscopy. PVD was thus considered to be complete. On the other hand, fluorescein angiography showed two areas of hyperfluorescence at the margin of the retinal nonperfusion area.
The present case underscores the importance of periodic follow-up using fluorescein angiography, given the probability of retinal neovascularization development and proliferative changes for many years even in diabetic retinopathy associated with complete PVD.
报告一例尽管完全性玻璃体后脱离（PVD）仍在糖尿病视网膜病变背景下发生视网膜新生血管的病例。
一名76岁男性患II型糖尿病30多年。通过直接和间接检眼镜检查发现了Weiss环。因此认为PVD是完全性的。另一方面，荧光素血管造影显示在视网膜无灌注区边缘有两个高荧光区域。
本病例强调了即使在伴有完全性PVD的糖尿病视网膜病变中，多年来仍有发生视网膜新生血管和增殖性改变的可能性，因此定期使用荧光素血管造影进行随访的重要性。
