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]
Causes
Diagnosis
Differential diagnosis
| 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 |
Treatment
Pseudopterygium can be removed by surgical excision.[7]
