    General Discussion
    Leber's Congenital Amaurosis (LCA) is a rare genetic eye disorder. Affected infants are often blind at birth or loss their sight within the first few of years of life. Other symptoms may include crossed eyes (strabismus); rapid, involuntary eye movements (nystagmus); unusual sensitivity to light (photophobia); clouding of the lenses of the eyes (cataracts); and/or abnormal protrusion of the front (anterior), clear portion of the eye through which light passes (cornea) (keratoconus). In addition, some infants may exhibit hearing loss, mental retardation, and/or a delay in the acquisition of skills that require the coordination of mental and muscular activity (psychomotor retardation). Leber?s Congenital Amaurosis is inherited as an autosomal recessive genetic trait.
