Electroretinography and Pupillography in Unilateral Foveal Hypoplasia.

The authors describe a 3-year-old boy with unilateral foveal hypoplasia and an absence of other ocular or systemic findings. Electroretinography obtained predominantly affecting cones. Laterality of pupil constriction to red but not to blue light was observed. The colored-light pupil response can be used to predict the retinal state. Copyright 2016, SLACK Incorporated.
