Living with Syndromic orbital border hypoplasia

A very rare condition present at birth in which the bony rim of the eye socket and tear drainage are underdeveloped.

Understanding Syndromic orbital border hypoplasia

Syndromic orbital border hypoplasia is a rare condition seen in two families, with an underdeveloped bony rim around the eye.

The edge of the eye socket may be missing. There are varying differences in the tear drainage passages, the eyelid skin and plates are underdeveloped, and the tear duct is blocked (nasolacrimal duct atresia). Signs are present in the newborn period.
