Which condition presents with a band-shaped growth from the conjunctiva onto the cornea?

• A. Keratitis
• B. Pterygium
• C. Giant Papillary conjunctivitis
• D. Hyphema

Answer: (B)

A band-shaped growth from the conjunctiva onto the cornea is characteristic of pterygium. This is a fibrovascular proliferation that typically begins at the nasal limbus and gradually extends across the corneal surface. It can cause astigmatism or visual disturbance if it advances toward the central cornea. Pterygium is often related to sun/UV exposure and dry eye. Keratitis involves inflammation or infection of the cornea itself, not a conjunctival band invading the cornea. Giant papillary conjunctivitis features large papillae on the inner surface of the eyelids from allergic or contact lens irritation, not a corneal encroachment. Hyphema is blood in the anterior chamber, unrelated to a conjunctival band growing onto the cornea.
