Ophthalmoscopy was performed on 483 normal newborn infants to determine the incidence of opticcup asymmetry and to compare this with glaucomatons infants. The incidence of marked optic cup asymmetry in normal newborn infants is 0.6 per cent in contrast to 89.0 per cent in monocular glaucomatous infants. The incidence of optic cups greater than 1/3 disc diameter in eyes of normal newborn infants is 2.6 per cent in contrast to 61.0 per cent in infantile glaucoma eyes. These findings underscore the importance of ophthalmoscopic evaluation of the optic discs in the congenital glaucomas.
