Abstract
The grating acuity and visual fields were assessed of 48 infants with bronchopulmonary dysplasia (BPD) who had no periventricular leukomalacia or grade III or IV intraventricular hemorrhage, and no stage 3 or greater retinopathy of prematurity. Infants were tested at four, eight, 11, 17 and 24 months corrected age, and their results were compared with those of 81 healthy preterm infants and 54 with hyaline membrane disease (HMD) that did not result in BPD. The BPD group showed no significant difference in acuity development compared with the healthy preterm and HMD groups. Infants with BPD had significantly smaller visual fields than either control group at 11 months; visual field development was similar for all groups at all other test ages. The authors conclude that infants with BPD who have no significant ocular or neurological complications show normal grating acuity and visual field development during the first two years of life.
