The exact function of these genes has not been clearly established. Differential diagnosis Patients with IEL by definition do not have associated systemic abnormalities, although cardiac and skeletal examinations should be performed to help exclude Marfan syndrome diagnosed according to the Ghent criteria see this term.

Prognosis Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications.

Clinical description Patients with IEL are found to have dislocation of the lens, which crietallin present at any age, but may be present from birth. Mutations in the former are thought to be the most important cause of this condition in Europeans. The primary aim of treatment in children is to prevent amblyopia through early correction of refractive errors.
Treatment of the resulting aphakia may be with contact lenses. In more severe cases, the anomaly is generally detected earlier with a greater impact on visual acuity.
Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients.
Dh, an intraocular lens IOL may be inserted in the anterior chamber, and sutured or glued into the posterior chamber or into the capsule, if it has been preserved during surgery. Isolated ectopia lentis IEL is a rare, clinically variable, eye disorder characterized by dislocation of the lens, often causing significant reduction in visual acuity.
Antenatal diagnosis Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified.
Patients with IEL are found to have dislocation of the lens, which may present at any age, but may be present from birth. Diagnostic methods Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.
Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications. Specialised Social Services Eurordis directory.
