What is the name for the fibrovascular growth that invades the cornea and originates in the conjunctiva?

The fibrovascular growth that invades the cornea and originates in the conjunctiva is called a pterygium. This condition typically occurs due to UV exposure, dryness, and irritation, leading to a fleshy, triangular growth that extends onto the corneal surface. The nature of a pterygium involves fibrovascular tissue, which consists of fibrous connective tissue and blood vessels, further illustrating its growth characteristics. Understanding its origin from the conjunctiva and its trajectory onto the cornea is crucial for recognizing the condition and applying appropriate management.

Other options include variations of eye lesions or conditions, such as a chalazion, which is a blocked oil gland, and a pingueculum, which is a benign, yellowish growth on the conjunctiva but does not invade the cornea. Keratosis refers to a skin condition involving thickening of the outer layer and is not specific to the eye. This context helps clarify why the pterygium is distinct in its characteristics and behavior compared to other options.
