Pseudopterygium is seen arrow (and calcified plaque)
CausesPost inflammatory
Diagnostic methodEye examination
Differential diagnosisPterygium

Pseudopterygium is the conjunctival adhesion to cornea caused by limbal or corneal inflammation or trauma. The pseudopterygium can be easily distinguished from pterygium by bowman's probe test.[1] Because of the lack of adherence of pseudopterygium at every point, the probe can be passed beneath it at some point.

Signs and symptoms

The presentation is clinging of conjunctiva to the peripheral cornea[2]



Differential diagnosis

Difference between pterygium and pseudopterygium
Pterygium Pseudopterygium
Etiology Degenerative process Inflammatory process
Age Common in adults[6] Occur in any age
Site Horizontally, most commonly nasally[5] Anywhere
Status Progressive(commonly) or stationary[6] Always stationary
Neck Adherent to limbus[6] Free
Probe test Probe cannot be passed underneath Probe can be passed under neck


Pseudopterygium can be removed by surgical excision.[7]
