The course of the vitreoretinal relationship in 272 eyes with diabetic retinopathy was studied retrospectively in an attempt to identify the prognostic role of the vitreous. In eyes with initial nonproliferative diabetic retinopathy, the development of neovascularization had a positive correlation with eventual partial posterior vitreous detachment (PVD) and a negative correlation with complete PVD. In eyes with initial proliferative diabetic retinopathy, those with active vitreous changes had a poor prognosis and those with inactive vitreous changes, an apparently good prognosis. Photocoagulation for retinal neovascularization was successful in most eyes with stable no-PVD but less successful in eyes that progressed to partial PVD. Therefore, considering the diabetic vitreous changes from a prognostic standpoint, the data suggest that if early proliferative changes are observed, photocoagulation before partial PVD develops might be considered.
对272例糖尿病视网膜病变患者的玻璃体视网膜关系病程进行了回顾性研究，以确定玻璃体的预后作用。在初发非增殖性糖尿病视网膜病变患者中，新生血管形成与最终部分性玻璃体后脱离（PVD）呈正相关，与完全性PVD呈负相关。在初发增殖性糖尿病视网膜病变患者中，有活动性玻璃体改变者预后较差，无活动性玻璃体改变者预后明显较好。视网膜新生血管的光凝治疗在大多数无PVD稳定的眼中成功，但在进展为部分性PVD的眼中成功率较低。因此，从预后角度考虑糖尿病玻璃体改变，数据表明如果观察到早期增殖性改变，可考虑在部分性PVD发生前进行光凝治疗。
