Diagnosis

Lens dislocation related to Marfan syndrome.

Findings

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

Discussion

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.
