Only comments written in English can be processed. Other search option s Alphabetical list. Specialised Social Services Eurordis directory. The prevalence of IEL is not known. Other findings include congenital abnormalities of the iris, spherophakia, enlarged iris processes leading to abnormal eu angle, iridodonesis, lens coloboma, refractive errors hyperopia, myopia, astigmatismand early-onset cataract.

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.

Antenatal diagnosis Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified. Etiology Dislocation of the lens is the result of a loss of zonular fibers.

Diagnostic methods Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes. Ectopia lentis syndrome Familial ectopia lentis Prevalence: All patients found to have mutations in FBN1 should have regular cardiac examinations.

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

Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified. Surgical intervention may be considered by experienced ophthalmic surgeons. The primary aim of treatment in children is to prevent amblyopia through early correction of refractive errors.

Mutations in the former are thought to be the most important cause of this condition in Europeans. IEL does not involve systemic abnormalities. Clinical description Patients with IEL cristaloin found to have dislocation of the lens, which may present at any age, but may be present from birth. Dislocation of the lens can be very mild leading to late diagnosis. Summary and related texts.

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.

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

Ectopia lentis is also a dk of homocystinuria, sulfite oxidase deficiency, Weill-Marchesani syndrome, aniridia, and Knobloch syndrome see these termsas well as pseudoexfoliation.

Patients with IEL are found to have dislocation of the lens, which may present at any age, but may be present from birth.

The exact function of these genes has not been clearly established. About 90 cases have been reported to date, primarily in Europeans.

Dislocation of ectopiie lens is the result of a loss of zonular fibers. Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.

Complications include loss of accommodation, secondary glaucoma, and retinal detachment. Lensectomy may be considered dy patients with cataracts, in cases where the ectopic lens affects vision significantly.

Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. Additional information Further information on this disease Classification s 4 Gene s 2 Clinical signs and symptoms Other website s 2.

Management and treatment Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. 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.

Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Lens dislocation may be progressive. Ocular findings vary widely within families, and between the eyes in an affected individual.

A standard approach should be adopted in cases of retinal detachment. They may develop amblyopia. 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. 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.

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.
