A rare case of ocular pterygium in a young boy with congenital lamellar ichthyosis

Abstract

Congenital lamellar ichthyosis is a rare dermato-ocular disease occurring in 1:300,000 population and is autosomal recessive. The most common ocular manifestation reported is cicatricial ectropion. Other symptoms include exposure keratopathy (secondary to ectropion), trichiasis, madarosis, deficit of the meibomian glands, and absence of lacrimal punctum. There are no reports of primary conjunctival involvement. We report a case of grade 3 pterygium in a young boy with congenital lamellar ichthyosis probably secondary to limbal stem cell deficiency.
