Bilateral granular dystrophy: A clinicopathogenetic correlation after alcohol assisted debridement with phototherapeutic keratectomy

Abstract

Bilateral corneal dystrophy includes a group of genetically determined, non-inflammatory corneal diseases, which result in loss of corneal transparency and visual impairment.1 Earlier, the classification of corneal dystrophy was solely anatomically based. However, the newer classification system based on recommendations of the International Committee for Classification of the Corneal Dystrophies (IC3D)2 has incorporated clinical findings, pathological characteristics and genetic basis, thereby giving a complete insight into each dystrophy, and has also enabled easy adaptation to advances in understanding from the continued discovery of new genes and mutations.
