Posterior keratoconus is a rare
corneal disorder that results in non-inflammatory thinning of the cornea,
leading to cone-like protuberance in the posterior cornea. Ocular coloboma is malformation due to faulty closure of the embryonic fissure, where the entire
ocular structure may affect iris, ciliary body, choroid, optic nerve or all of
the above. Posterior keratoconus may lead to vision loss over a period of time.
A rare case of both Posterior keratoconus along with Ocular coloboma was
presented here. The study predict genetic linkage as one of the reasons and
suggest further studies to explore the link between Posterior keratoconus and
the Ocular coloboma.
