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.
