Pterygium is a medical term for a benign, wedge-shaped growth on the conjunctiva that can extend onto the cornea. It often begins on the nasal side of the eye and may cause irritation or visual distortion if it enlarges. The word is used mainly in ophthalmology and medical discussions, not in everyday speech.
