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. Because of the lack of adherence of pseudopterygium at every point, the probe can be passed beneath it at some point.
