Autosomal recessive ectopia lentis in two Arab family pedigrees.

Nineteen patients with bilateral ectopia lentis and no other ocular abnormalities in two Arab families are described. The two family pedigrees demonstrate an autosomal recessive inheritance in contrast to the majority of reported family pedigrees with this condition which show dominant inheritance. The early onset of the condition, its natural course and its consequences on visual function are described.
