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.
Causes
Differential diagnosis
| Pterygium | Pseudopterygium | |
|---|---|---|
| Etiology | Degenerative process | Inflammatory process |
| Age | Common in adults [5] | Occur in any age |
| Site | Horizontally, most commonly nasally [4] | Anywhere |
| Status | Progressive(commonly) or stationary [5] | Always stationary |
| Neck | Adherent to limbus [5] | Free |
| Probe test | Probe cannot be passed underneath | Probe can be passed under neck |
Treatment
Pseudopterygium can be removed by surgical excision. [6]
