Lens dislocation may be progressive. Check this box if you wish to receive a copy of your message. IEL does not involve systemic abnormalities. Health care resources for this disease Expert centres Diagnostic tests 63 Patient organisations 38 Orphan drug s 0. Complications include loss of accommodation, secondary glaucoma, and retinal detachment.

Ocular findings vary widely within families, and between the eyes in an affected individual. About 90 cases have been reported to date, primarily in Europeans. Dislocation of the lens is the result of a loss of zonular fibers. Etiology Dislocation of the lens is the result of a loss of zonular fibers.

The prevalence of IEL is not known. Diagnostic methods Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.

The primary aim of treatment in children is to prevent amblyopia through early correction of refractive errors.

Antenatal diagnosis Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified. Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified.

Dislocation of the lens can be very mild leading to late diagnosis. Management and treatment Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. Visual acuity, refractive error, and intraocular pressure ectopiie be monitored regularly in affected patients. Mutations in the former are thought to be the most important cause of this condition in Europeans.

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 cristaklin.

They may develop amblyopia. Surgical intervention extopie be considered by experienced ophthalmic surgeons. All patients found to have mutations in FBN1 should have regular cardiac examinations.

The exact function of these genes has not been clearly established. Disease definition Isolated ectopia lentis IEL is a rare, clinically variable, eye disorder characterized by dislocation of the lens, often causing significant reduction in visual acuity.

In more severe cases, the anomaly is generally detected earlier with a greater impact on visual acuity. For all other comments, please send your remarks via contact us.

Patients with IEL are found to have dislocation of the lens, which may present at any age, but may be present from birth. Other findings include congenital abnormalities of the iris, spherophakia, enlarged iris processes leading to abnormal iridocorneal angle, iridodonesis, lens coloboma, refractive errors hyperopia, myopia, astigmatismand early-onset cataract.

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. Detailed information Article for general public Suomipdf.

Only comments written in English can be processed. Alternatively, 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.

Lensectomy may be considered in patients with cataracts, in cases where the ectopic lens affects vision significantly. Some patients are also found to have displacement of the pupils, usually in the opposite direction to lens displacement known as ectopia lentis et pupillae.

Prognosis Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications. Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications. A standard approach should be adopted in cases of retinal detachment.

Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes. Clinical description Patients with IEL are found to have dislocation of the lens, which may present at any age, but may be present from birth.

Treatment of the resulting aphakia may be with contact lenses. Ectopia lentis syndrome Familial ectopia lentis Prevalence: Ectopia lentis is also a feature of homocystinuria, sulfite oxidase deficiency, Weill-Marchesani syndrome, aniridia, and Knobloch syndrome see these termsas well as pseudoexfoliation.

Isolated ectopia lentis IEL is a rare, clinically variable, eye disorder characterized by dislocation of the lens, often causing significant reduction in visual acuity.
