Abstract

To classify the ophthalmoscopic appearance of the developing macula, I performed retinal examinations on 129 premature neonates. In normal infants, the classification ranged from 34 weeks of gestational age when pigment was first evident in the macula, through the development of the annular ring reflex of the macula and foveolar reflex, to a mature (adult-appearing) macula at 42 weeks. This sequence allowed the observer to estimate the gestational age of the older premature neonate from the appearance of the macular area. Babies who had, or subsequently developed, retinopathy of prematurity showed a statistically significant two-week delay in macular development in the later stages. This may be the first evidence of a direct macular insult in retinopathy of prematurity.
