Anterior dystrophies superficial dystrophies It primarily affecting epithelium and Bowman;s layer. 1. Epithelial basement membrane dystrophy 2. Reis-Buckler;s dystrophy. 3. Meesman;s dystrophy. 4. Recurrent corneal erosion syndrome. 5. Stocker-Holt dystrophy. II. Stromal dystrophies 1. Granular Groenouw;s type I dystrophy 2. Lattice dystrophy 3. Macular Groenouw;s type II dystrophy 4. Crystalline Schnyder;s dystrophy III. Posterior dystrophies affecting primarily the corneal endothelium and Descemet;s membrane. 1. Cornea guttata 2. Fuchs; epithelial-endothelial dystrophy late hereditary endothelial dystrophy. 3. Posterior polymorphous dystrophy of Schlichting. 4. Congenital hereditary endothelial dystrophy CHED. STROMAL DYSTROPHIES Macular dystrophy Groenouw type-II It is an autosomal recessive dystrophy characterised by appearance of dense grey opacity in the central cornea. The condition results due to accumulation of mucopolysaccharides owing to a local enzyme deficiency. It occurs in childhood 5 to 10 years and leads to marked defective vision in early life, which usually requires penetrating keratoplasty. Ref:-A K KHURANA; pg num:-117,118
