Pseudo-pterygium

This 46 year-old man was concerned about the appearance of his left eye. He gave a history of corneal trauma sustained 15 years ago. Since then, there had been a pterygium-liked lesion developing. In the past few year, he noticed the cornea adjacent to the lesion was getting progressively whiter. Examination revealed a pterygium-liked lesion extending from the lower pterygium (normal pterygium extend horizontally from the sun-exposed caruncle area) and the presence of lipid keratopathy at the edge of the lesion. A simple excision was performed but the lesion recurred. We planned to re-excise the lesion with a conjunctival graft. If the lesion were to recur, further surgery may involve autologous limbal stem cell transplant with concurrent amniotic membrane graft.
