Pterygium Twins

Pterygium is one of the most frequent pathologies in ophthalmology, with a prevalence of approximately 12%.[1] It is a benign fibrovascular proliferation of conjunctival tissue; it has a typical resemblance to an insect wing.[2] Clinically, the pterygium is presented along the interpalpebral fissure as a triangular yellow–white fleshy proliferation of conjunctival tissue.[3,4] It consists of a head (leading edge) and a tail. Sporadically, pterygium occurs temporally or as 2-headed pterygia on both nasally and temporally origins.[3,4] We present the case of an atypical anatomic variation of this benign pathology observed in a 55-year-old-man, with no pathological history. He presented for a routine ophthalmologic visit, during which he was found to have bilateral pterygium in both eyes. But in the biomicroscopic examination of the right eye with diffuse illumination [Figure 1], we found an atypical presentation of pterygium; it was a double pterygia on the nasal side with a double head and double tail: pterygium twins!Figure 1: Photographs of the anterior segment of the right eye reveal the presence of two distinct pterygia on the nasal sideFinancial support and sponsorship Nil.
