Question

True statement about the given condition of the eye except:

• A. Arise from any part of conjunctiva
• B. Can cause Astigmatism
• C. Surgery is treatment of choice
• D. UV exposure is risk factor

Hint:

Pterygium is always in the interpalpebral fissure, not just any part of conjunctiva.

Answer 1

The Correct Option is A

Step 1: The clinical picture is a pterygium - a triangular, vascularised fibrovascular growth of bulbar conjunctiva creeping over the cornea, classically in the area of the open palpebral fissure on the nasal limbus.
Step 2: This is a negative-marking ("except") item, so we must isolate the statement that does NOT hold true. A pterygium is confined to the interpalpebral zone; it never originates from random or any part of the conjunctiva. Statement (a) is therefore incorrect about pterygium.
Step 3: Reviewing the remaining choices: corneal flattening from the advancing head produces astigmatism, validating (b); chronic ultraviolet exposure is a well-documented aetiological factor, validating (d); and definitive management when progressive is surgical removal, validating (c).
Step 4: Because the only untrue claim is that the lesion can come from any conjunctival site, that option is selected.
\[\boxed{\text{Arise from any part of conjunctiva}}\]
