Gelatinous Drop-Like Corneal Dystrophy – 2 Clinical Cases

Abstract

Gelatinous drop-like corneal dystrophy is a very rare autosomal recessive disease classified as an epithelial and subepithelial corneal dystrophy. Patients typically present under the age of 20 with drop-like corneal lesions showing high corneal fluorescein uptake. Their disease course is typically protracted and prone to frequent relapses. The condition is caused by a dysfunction of the epithelial barrier, leading to protein deposits most likely originating from tear fluid. Histology typically shows subepithelial amyloid deposits with corresponding defects of Bowmanʼs layer and epithelial atrophy. Where topical lubricating and anti-inflammatory therapy proves insufficient, penetrating allogenic limbokeratoplasty can be considered in a curative approach. In this report, we present disease courses of 2 unrelated patients. Current findings on pathogenesis are discussed.
