Stereopsis in the Infant Aphakia Treatment Study: comparison between ages 4½ and 10½

Abstract

Infants born with a unilateral congenital cataract (UCC) are frequently unable to perceive depth based on binocular cues because of the patching regimen employed to ensure optimal vision in the treated eye, as well as the disparity in acuity between their eyes. At the 4½ year visual assessment approximately 25% of the IATS patients demonstrated some level of binocular functioning. We determined that retesting stereopsis at age 10½ years would provide valuable information.
