Abstract
1). Regular ophthalmoscopic examination was conducted in the prematurity ward in the National Children Hospital in Tokyo from Sep. 1965 to Aug. 1966 with a view to detect the retinopathy of prematurity.
Out of 78 premature infants studied, 13 cases developed retinopathy of prematurity. Spontaneous regression or improvement by treatment took place in 8 cases with initially active disease, while the remaining 5 cases healed with extensive scar formation. The incidence of retinopathy was inversely related with the birth weight and was frequent found in cases who showed prematurity fundus characteristics which are more closely described in the text.
2). 40 cases with retrolental fibroplasia of cicatricial stage were detected in the policlinic and were studied for the visual and ocular defects. Eyes affected with severe retinopathy of grade IV or V were invariably blind, while those of grade II or III had handicapped vision ranging from 20/30 to 3/200. Myopia or myopic astigmatism were often associated with mild or moderate retinopathy of prematurity.
In eyes with grade II retinopathy tempolar scars may produce heterotropia of the macula which results in pseudo-exotropia.
