Iridodonesis or tremulous iris is a clinical sign of ectopia lentis which is frequently associated with homocystinuria. We present a forty-two-year-old woman victim of a left middle cerebral artery ischemic stroke. The clinical examination found bilateral iridodonesis and laboratory tests showed an increased level of serum homocysteine and homocystinuria. Homocystinuria was caused by a compound heterozygous I278T and D444N mutation of cystathionine beta-synthase (CBS) gene and also a C667T heterozygous polymorphism of methylene-tetrahydrofolate-reductase gene. This case was atypical because of the incomplete phenotype, development of complications in adulthood and the association of a rare compound heterozygous mutation of the CBS gene.
