后部玻璃体脱离发生于老年人,且与许多眼病有关。它在包括裂孔源性视网膜脱离、牵引性视网膜脱离、增殖性糖尿病性视网膜病变等玻璃体视网膜疾病中起重要作用。目前对后部玻璃体脱离的发生机理仍不清楚,其原因部分是由于缺乏动物实验模型,另外一方面,玻璃体附着于内界膜的基础也不清楚。尽管人们还不了解玻璃体与视网膜的附着,但有理由认 Posterior vitreous detachment occurs in the elderly and is associated with many ocular diseases. It plays an important role in vitreoretinal diseases, including retinal detachment, traumatic retinal detachment, proliferative diabetic retinopathy and the like. The current mechanism of the posterior vitreous detachment remains unclear, partly because of the lack of animal models and, on the other hand, the basis for the attachment of the vitreous to the endocardium. Although people do not understand the vitreous and retinal attachment, but there is reason to recognize
