Diseases leading to corneal opacities are inflammations, infections, metabolic causes, trauma, or genetically determined diseases. Corneal dystrophies may lead to corneal blindness. A clinical and pathological review of 2,108 corneal specimens received from December 1983 to January 1988 revealed 86 (4%) corneal specimens with corneal dystrophies. Fifty-three (62%) patients had macular dystrophy, 11 (13%) had congenital hereditary endothelial dystrophy (CHED), 12 (14%) had Fuchs' corneal dystrophy, 5 (6%) had lattice corneal dystrophy, and 3 (4%) had granular dystrophy. Macular dystrophy appears to be the most common cause of corneal dystrophy in Saudi Arabia. Twenty-two (42%) patients with macular dystrophy and 10 (91%) patients with CHED were the result of consanguineous marriages. Genetic counseling is advisable among families who carry the trait of CHED or macular corneal dystrophy.
