Retinal Aplasia
Sorsby and Williams (1960) observed a family with multiple cases of retinal aplasia in which inheritance was autosomal dominant. 'Retinal aplasia' is the British term for what is called 'congenital amaurosis' on the continent. Much genetic heterogeneity exists as evidenced by the demonstration of both autosomal dominant and autosomal recessive forms. This disorder, which might be called an autosomal dominant form of Leber amaurosis congenita, must be very rare. Heckenlively (1988) reported a 6-generation family with a severe progressive retinal degeneration beginning in infancy.
