Which of the following corneal dystrophies is an autosomal recessive condition
CORNEAL DYSTROPHIES CLASSIFICATION Dystrophies are classified according to the anatomic site most severely (primarily) involved, as follows: I. 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
