- Clinical features:
- Adhesion of the conjunctiva to the peripheral cornea.
- May occur on any quadrant of the cornea.
- Lacks firm adhesion throughout the underlying structures, and
occasionally has a broad leading edge on the corneal surface.
- These findings differentiate it from true pterygium.
- Pseudopterygium may result from a peripheral corneal ulcer and ocular
surface inflammation such as cicatrizing conjunctivitis, chemical
burns, or may also occur secondary to chronic mechanical irritation
from contact lens movement associated with inadequate lubrication
of the corneal surface.
