Pseudogerontoxon

Abstract

Pseudogerontoxon is a lesion that resembles a small segment of arcus senilis or gerontoxon and is seen in many individuals with limbal vernal or atopic keratoconjunctivitis. It is an important clinical finding because pseudogerontoxon is often times the only clinical evidence of previous allergic eye disease. To the authors' knowledge, pseudogerontoxon has only rarely been mentioned, and has never been pictured, in the peer-reviewed literature. Three examples are presented of this important clinical entity.
