糖尿病患者体内持续的高血糖及相应的病理状态不仅会导致糖尿病视网膜病变(DR)，也会影响玻璃体代谢，导致糖尿病玻璃体病变。由于玻璃体与视网膜在解剖位置上毗邻，因此糖尿病玻璃体病变与DR在发生发展方面相互促进，特别是玻璃体后脱离(PVD)和玻璃体劈裂等玻璃体视网膜界面的改变，为纤维血管增殖膜的生长提供了支架，并与玻璃体切割术(PPV)术中操作密切相关。本文整理了糖尿病患者玻璃体结构及胶原交联产物改变、玻璃体视网膜界面改变及其与增殖性糖尿病视网膜病变(PDR)关系的相关研究，旨在深入了解糖尿病玻璃体病变，为DR的研究和治疗、PPV手术方案的制定等提供参考。

When it comes to diabetic patients, persistent hyperglycemia and associated pathological conditions will not only cause diabetic retinopathy(DR)but also have an impact on the metabolism of vitreous, leading to diabetic vitreopathy. Owing to the adjacent anatomical position between the vitreous and retina, diabetic vitreopathy and DR are mutually promoted. Changes in vitreoretinal interface such as posterior vitreous detachment(PVD)and vitreoschisis, provide a scaffold for fibrovascular proliferative membrane and are closely associated with pars plana vitrectomy(PPV). This article sorts out the variation of diabetic patients' vitreous structure and biochemical components, along with the changes in the vitreous-retinal interface, particularly for the related research on its relationship with proliferative diabetic retinopathy(PDR), aiming at providing further cognition of diabetic vitreopathy as well as references for DR treatment and formulation of PPV.
