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

• A. Chalazion
• B. Pterygium
• C. Strabismus
• D. Ecchymosis

Answer: (B)

The condition characterized by a fleshy encroachment of conjunctiva onto the cornea is known as a pterygium. This benign growth typically starts as a thickening of the conjunctiva that gradually extends onto the corneal surface, often presenting as a triangular-shaped tissue. Pterygium is commonly associated with environmental factors, such as prolonged exposure to UV light, dust, and wind, which can irritate the eye and contribute to the growth of this tissue. In terms of other options, a chalazion is a cyst that forms as a result of a blocked oil gland in the eyelid and does not involve the cornea. Strabismus refers to a condition where the eyes do not properly align with each other, affecting vision rather than the physical encroachment of tissue. Ecchymosis, on the other hand, describes bruising or discoloration of the skin due to bleeding underneath it, and it does not pertain to changes in the conjunctiva or cornea. Thus, among these choices, pterygium is the only condition specifically related to the encroachment of conjunctival tissue onto the cornea.
