The Retinal Society classification on proliferative vitreoretinopathy of 1983 has been updated to accommodate major progress in understanding of this disease. There are three grades describing increasing severity of the disease. Posterior and anterior location of the proliferations have been emphasized. A more detailed description of posterior and anterior contractions has been made possible by adding contraction types such as focal, diffuse, subretinal, circumferential contraction, and anterior displacement. The extent of the abnormality has been detailed by using clock hours instead of quadrants.
1983年视网膜协会关于增生性玻璃体视网膜病变的分类已更新，以适应对该疾病认识的重大进展。有三个等级描述疾病严重程度的增加。强调了增殖的后部和前部位置。通过增加如局限性、弥漫性、视网膜下、环形收缩和前部移位等收缩类型，对后部和前部收缩进行了更详细的描述。通过使用钟点数而非象限来详细说明异常的范围。
