High-Yield Explanation
Macula corneal dystrophy 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.Reference:Comprehensive ophthalmology,AK Khurana,4th edition,page no.118
