Abstract

The incidence of anisocoria in the newborn period is not well described. Additionally, the normal range of infant pupil size is not well defined. Eighty-eight healthy newborns were evaluated. Pupil size and color were obtained from photographs. The mean (±SD) pupil size was 3.8 ± 0.8 mm. There was no statistical difference between right and left eyes. A statistically significant difference in pupil size was found between blue and brown eyes. The incidence of anisocoria was found to be 21%. No difference was greater than 1.0 mm. The incidence of anisocoria was no different on the basis of eye color.
