Pterygia can range from relatively flat, transparent tissue with a few blood vessels in early stages to thick, opaque tissue that completely obstructs the line of vision. They often originate in the conjunctiva (a tissue that lines the inner corner of the eye) and can extend toward the cornea. They are typically benign (non-cancerous) growths, which do not spread beyond the surface of the eye.
Symptoms of Pterygia
In the early stages, a pterygium rarely exhibits any signs or symptoms. When it does, the symptoms are usually mild.
Early symptoms of pterygia include:
- Burning sensation
- Foreign body sensation
- Eye redness
Late symptoms of pterygia include:
