Massive study seeks clues to rare eye disorders in kids

This research study aims to learn more about children born with small or missing eyes (Microphthalmia, Anophthalmia, and Coloboma, or MAC) and how genetic changes may cause these conditions. Researchers will collect medical histories, saliva, and blood samples, and perform physical exams and imaging on up to 3,000 children and their families. The goal is to better understand the condition, not to test a treatment.
