| Differential diagnosis | Pterygium |
| Treatment | Surgery |
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 | |
|---|---|---|

| Status | Progressive(commonly) or stationary[5] | Always stationary |
