ectopie du cristallin et augmentation de la vergence inférieure – Docteur Damien Gatinel

vu 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. Ocular findings vary widely within families, and between the eyes in an affected individual. Lensectomy may be considered in patients with cataracts, in cases where the ectopic lens affects vision significantly.

Surgical intervention may be crietallin by experienced ophthalmic surgeons. Antenatal diagnosis Prenatal diagnosis for pregnancies at increased risk is possible if the disease-causing mutations in the family have been identified. Treatment of the resulting aphakia may be with contact lenses. They may develop amblyopia. The exact function of these genes has not been clearly established.

Etiology Dislocation of the lens is the result of a loss of zonular fibers. 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.

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

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.

The prevalence of IEL is not known. 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 criatallin surgery.

Summary and related texts. Other search option s Alphabetical list. Diagnostic methods Diagnosis is based on typical ocular findings through ophthalmologic examination and can be confirmed by molecular genetic testing of the causative genes.

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. All patients found to have mutations in FBN1 should have regular cardiac examinations.
