Ectopia lentis

Dislocation of the lens of the eye. It is one of the most important single indicators in diagnosing Marfan syndrome.

luxation of the lens

Pathological and complete dislocation of the lens relative to the pupil. If the luxation is incomplete it is called subluxation of the lens (or dislocation or ectopia lentis). Subluxation is one of the causes of monocular diplopia. If the luxation is complete the eye becomes markedly hyperopic and is unable to accommodate. Luxation occurs in contusion of the globe, in many ocular (e.g. buphthalmos) and other diseases (e.g. syphilis) or it can be inherited (e.g. the bilateral, symmetrical, superior subluxation commonly found in Marfan's syndrome or homocystinuria). It is sometimes associated with ectopic pupils and keratoconus. Unless there are complications (e.g. secondary glaucoma) or monocular diplopia the lens is left in place and management is optical. (Fig. L21) See corectopia; iridodonesis; pupillary block.

Twenty two (66.7%) eyes had non syndromic lens subluxation, 10 (30.3%) eyes had ectopia lentis due to Marfan's syndrome and 01 (3%) eye had traumatic lens subluxation.
The spectrum of overlapping disorders like EL (ectopia lentis), associated with FBN1 mutations, defines the molecular group of type1 fibrillinopathies (Oklu and Hesketh, 2000).
In addition to ectopia lentis, homocystinuria and Marfan syndrome share other common clinical findings, such as long-bone overgrowth, a high arched palate, a crowded dentition, and scoliosis.
(3) About one-half of patients with Marfan syndrome have ectopia lentis (dislocated lens).
A specific test result from a sterile catheterized urine specimen can rule out Marfan's syndrome when ectopia lentis is present.
Case records of patients under 18 years of age who underwent SFIOL for congenital ectopia lentis from January 2012 to December 2016 were analyzed.
