Which term describes the abnormal conjunctival growth that crosses the limbus and grows onto the cornea?

Explanation:
Crossing the limbus onto the cornea is characteristic of a pterygium. The limbus is the border between the cornea and sclera, and when conjunctival tissue grows across this border onto the corneal surface, it forms a pterygium, often appearing as a fibrovascular, triangular extension that can encroach on vision if it advances. The other terms refer to different structures or conditions: a semilunar fold is a small conjunctival fold at the inner corner of the eye (not crossing onto the cornea), puncta are the openings of the tear drainage system, and the retina is the light-sensitive layer at the back of the eye.
