title: A classification of retrolental fibroplasia to evaluate vitamin E therapy.
abstract: A refined classification of the stages of the retinopathy of prematurity (RLF) based on the experience of over 7500 examinations during the past decade is presented. We have been using the basic elements of this classification since 1972 in order to evaluate the influence of vitamin E on retrolental fibroplasia (RLF). It is our impression that it provides a more accurate clinical method of following the course of the retinopathy and a tool for assessing the factors other than prematurity and hyperoxia that may play a subtle role in the development of RLF.
