title: Observations on the retinopathy of prematurity.
abstract: The fourfold to fivefold increased survival rate since 1950 of premature infants with birthweights of less than 1,000 g apparently explains the increase in cases of retinopathy of prematurity in recent years. A new international classification permits standardized grading of the retinopathy of prematurity based on severity, anterior-posterior location, and the meridians involved. Previously reported clinical trials on the role of vitamin E in the prevention of retinopathy of prematurity have given conflicting results.
