Ectopia Lentis

Excerpt

Ectopia lentis refers to the hereditary or acquired malposition of the natural crystalline lens out of the patellar fossa. The first report came from Berry, who documented the first case of lenticular dislocation in 1749. Later, Stellwag was the first to name it ectopia lentis in 1856 in a patient with congenital dislocation of the lens. It can be hereditary (familial) or acquired. The lens can be subluxated or dislocated away from the patellar fossa. The cause can be traumatic or secondary to underlying systemic disease. The lens can be seen in the anterior chamber, vitreous phase, or retinal surface. Ectopia lentis can be a primary manifestation of a systemic disorder and should arouse suspicion of underlying systemic pathology. This is a disorder with varied etiologies.

A detailed past and systemic history are necessary in each case. The patient should be questioned regarding cardiovascular, skeletal, and any other ocular abnormalities. A thorough ocular and systemic examination help in clinching the diagnosis. Family members should also be evaluated to pinpoint the genetic association. The pediatrician also plays a crucial role in ruling out familial disorders. The patient's visual outcome depends on the degree and extent of subluxation or dislocation and the presence and absence of complications.
