Which condition is characterized by a fleshy encroachment of conjunctiva onto the cornea?

  1. Chalazion

  2. Pterygium

  3. Strabismus

  4. Ecchymosis

The correct answer is: Pterygium

The condition characterized by a fleshy encroachment of conjunctiva onto the cornea is pterygium. This growth typically appears as a triangular-shaped tissue and can extend from the conjunctiva over the cornea, which can lead to vision issues if it grows large enough to obstruct sight or cause irritation. Pterygia are often associated with environmental factors such as UV light exposure, and they can be symptomatic, causing redness, irritation, or astigmatism. In contrast, a chalazion is a cyst in the eyelid that results from blocked oil glands, strabismus refers to misalignment of the eyes, and ecchymosis indicates bruising or discoloration of the skin due to bleeding underneath. None of these conditions involve the growth of conjunctival tissue over the cornea, which is the defining feature of pterygium.
