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.

Vernal Keratoconjunctivitis Clinical Features and Complications in 123 Patients in Gaza Strip

“…(3) Macro-erosions of the cornea was seen in 1.6% of the cases and because of early presentation and the intensive management of these cases none of them developed shield ulcer. Pseudogerontoxon is a peripheral degenerative corneal opacity seen in patients with chronic limbal vernal keratoconjunctivitis; (20) this was found in a 16year old female patient with chronic mixed vernal keratoconjunctivitis. Keratoconus has been associated with atopy and eye rubbing.…”

Unilateral pseudogerontoxon

“…Another potential cause of arcus‐like corneal signs in young adult subjects is pseudogerontoxon, a local lipid deposit occurring in the peripheral cornea of patients with vernal keratoconjunctivitis (VKC) or atopic keratoconjunctivitis (AKC) that commonly accompanies the limbal forms of these conditions 7 . This report describes the clinical findings in a case of unilateral pseudogerontoxon occurring in a young adult patient.…”
