Non Infectious
Pseudopterygium

  • 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.
