Post corneal embryonic ring

There is a raised white line near the limbus, and a tissue band extends from the peripheral part of the iris to this white line. Axenfeld calls it the post-corneal embryonic ring. Post-corneal embryonic rings are a clinical manifestation caused by Axenfeld-Rieger abnormalities or syndromes.
