Pterygium is a common benign pathology of the eye. It is also known as surfer eye.
General
- Pronounced: "tuh-rij-ee-uhm".[1]
- Conjunctiva lesion that covers part of the sclera.
- Sclera = white part of the eye.[2]
- Benign.
- Due to ultraviolet light exposure, i.e. sunlight.[3]
Gross
- Medial aspect of eye - covers sclera (white part) and part of the iris (coloured part).
