Abstract

THE DISK-SHAPED, or ring, cataract is a rare form of congenital cataract that has been reported relatively few times. Judging from a review of the literature, the hereditary tendency has been reported in only 1 family.

In addition to the cataract, all the affected members examined showed symmetric dislocation of the lens. No other local or systemic anomalies were found. This family is not related to any other with congenital cataract, and, so far as I can trace the familial history, there were no known cases of this condition prior to the ones reported herein.
