Which term describes an eye condition where the conjunctiva grows over the cornea?

• A. Dry Eye Syndrome
• B. Pterygium
• C. Lazy Eye
• D. Subconjunctival Hemmorhage

Answer: (B)

Think about conditions where tissue from the conjunctiva extends onto the surface of the eye. The term that describes this growing tissue moving from the conjunctiva onto the cornea is pterygium. It usually starts on the nasal (inner) side of the eye as a fleshy, triangular, fibrovascular band that can creep onto the corneal surface. UV exposure, wind, dust, and dry environments increase its risk. It may be harmless or, if it encroaches on the central cornea, can blur vision or cause astigmatism, sometimes needing surgical removal if it threatens sight or causes irritation. Dry Eye Syndrome involves insufficient tear production or quality, leading to a sensation of dryness and irritation but no tissue overgrowth onto the cornea. Lazy Eye (amblyopia) is reduced vision due to brain suppression of input from one eye, not a surface lesion. Subconjunctival Hemorrhage is bleeding under the conjunctiva, appearing as a red patch, and does not involve growth onto the cornea.
