Ectopia lentis syndrome Familial ectopia lentis Prevalence: 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.
Health care resources for this disease Expert centres Diagnostic tests 63 Patient organisations 38 Orphan drug s 0. 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. Specialised Social Services Eurordis ectopei.
Surgical intervention may be considered by experienced ophthalmic surgeons. Prognosis Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications. The exact function of these genes has not been clearly established.
Only comments written in English can be processed. 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.
Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. 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. They may develop amblyopia. Summary and related texts. 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.
Isolated ectopia lentis IEL is a rare, clinically variable, eye disorder characterized by dislocation of the lens, often causing significant reduction in visual acuity. Lens dislocation may be progressive.
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 cristallinn to the Ghent criteria see this term. Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted.

Complications include loss of accommodation, secondary glaucoma, and retinal detachment. Management cristqllin treatment Visual acuity, refractive error, and intraocular pressure should be monitored regularly in affected patients. Mutations in the former are thought to be the most important cause of this condition in Europeans.

Additional information Further information on this disease Classification s 4 Gene s 2 Cristalpin signs and symptoms Other website s 2.
About 90 cases have been reported to date, primarily in Europeans. Diagnostic methods Diagnosis is crsitallin on typical ocular cristalli through ophthalmologic examination and can be confirmed by molecular cristzllin testing of the causative genes. 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.

Antenatal diagnosis Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified. 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.
Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.

Dislocation of the lens can be very mild leading to late diagnosis. Visual prognosis depends on the degree of lens dislocation, the age of onset, age of treatment and complications. Lensectomy may be considered in patients with cataracts, in cases where the ectopic lens affects vision significantly. Ectopia lentis is also a feature of homocystinuria, sulfite oxidase deficiency, Weill-Marchesani syndrome, aniridia, and Knobloch syndrome see these termsas well as pseudoexfoliation.
