Lens dislocation related to Marfan syndrome.


Lenticular dislocation (ectopia lentis) related to lax suspensory ligaments.


Marfan syndrome is an autosomal dominant genetic disorder with variable expression resulting in a defective fibrillin-1 protein (a component of elastin). The mutation is sporadic in 15-30%. Abnormalities associated with Marfan syndrome include: scoliosis, pectus deformity, cardiac valve dysfunction, arterial aneurysm and dissection, intestinal hernias and diverticula, joint laxity, pulmonary blebs, liver and renal cysts, and arachnodactyly.
