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. Patients with IEL are found to have dislocation of the lens, which may present at any age, but may be present from birth. Ectopia lentis is also a feature of homocystinuria, sulfite oxidase deficiency, Weill-Marchesani syndrome, aniridia, and Knobloch syndrome see these termsas well as pseudoexfoliation.

Ocular findings vary widely within families, and between the eyes in an affected individual.

Summary and related texts. A standard approach should be adopted in cases of retinal detachment. Prognosis Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications. Etiology Dislocation of the lens is the result of a loss of zonular fibers. Other search option s Alphabetical list. About 90 cases have been reported to date, primarily in Europeans. Ectopia lentis syndrome Familial ectopia lentis Prevalence: Health care resources for this disease Expert centres Diagnostic tests 63 Patient organisations 38 Orphan drug s 0.

Mutations in the former are thought to be the most important cause of this condition in Europeans.

Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and ectoipe. The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment. Complications include loss of accommodation, secondary glaucoma, and retinal detachment. Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified.

Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. In more severe cases, the anomaly is generally detected earlier with a greater impact on visual acuity. 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. The documents contained in this web site are presented for information purposes only. Surgical intervention may be considered by experienced ophthalmic surgeons.

Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Differential diagnosis Ectopei 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 ectopue see this term. All patients found to have mutations in FBN1 should have regular cardiac examinations. They may develop amblyopia. Dislocation of the lens is the result of a loss of zonular fibers.

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.

The primary aim cristalkin treatment in children is to prevent amblyopia through early correction of refractive errors. 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. The prevalence of IEL is not known.

Only comments written in English can be processed.

Diagnostic methods Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.

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.

The exact dk of these genes has not been clearly established. Management and treatment Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. Lensectomy may be considered in patients with cataracts, in cases where the ectopic lens affects vision significantly. Check this box if you wish to receive a copy of your eu. Lens dislocation may be progressive.

Treatment of the resulting aphakia may be with contact lenses. Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.

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.

Dislocation of the lens can be very mild leading to late diagnosis.
