Granular Corneal Dystrophy Type II

Abstract

A paradigm shift has been observed in the classification of Granular corneal dystrophies (GCD). GCD is a bilateral, progressive, genetically determined and non-inflammatory disease limited to the cornea that has an autosomal dominant mode of inheritance. A 28 year old young male presented to us without any visual complaints. The examination of his cornea revealed the presence of diffuse linear, multiple round to granular, bread crumb like and stellate opacities extending from the sub-epithelium migrating down till the deep stroma, the classical clinical features of a heterozygous phenotypic variant of GCD type II. It progresses slowly and majority of the affected patients maintain a stable vision. Since this patient was asymptomatic therefore a complete ophthalmic examination in routine cases presenting to the oupatient clinics is indispensible. Various management options exist but a definitive treatment option is lacking.
