Bilateral crystalline lens dislocation associated with dilated cardiomyopathy in a patient with underlying hyperhomocysteinaemia

摘要

Ectopia lends is described as dislocation of the crystalline lens of the eye. A partial displacement of a lens is termed lens sub-luxation, whereas a complete dislocation is termed lens luxation.When not associated with trauma, ectopia lentis should prompt suspicion of associated hereditary systemic disease or related ocular disorders. Numerous systemic conditions are associated with ectopia lentis. Most common are Marfan's syndrome and homocystinurea, Weill-Marchesani syndrome, sulphite oxidase deficiency and hyperlysinaemia. Least common are conditions such as Ehlers-Danlos syndrome, Crouzon's syndrome, Refsum's syndrome, mandibulafacial dys-ostosis, Sturge-Weber syndrome, Conra-di's syndrome, Pflaunder's syndrome, Pierre Robin syndrome, Wildervanck's syndrome and Sprengal's deformity.
