International classification of retrolental fibroplasia: a proposal

Abstract

There is evidence that, owing to the increased rate of salvage of premature infants weighing less than 1500 g at birth, the incidence of both retinopathy of prematurity (acute retrolental fibroplasia) and cicatricial retrolental fibroplasia is increasing. Treatment of the acute process to prevent blindness is controversial. In order that adequate studies be conducted to settle this issue, an international classification of retrolental fibroplasia is proposed.
