Leber's Congenital Amaurosis

Background

Leber's Congenital Amaurosis (LCA) is a rare inherited retinal disorder in which there is poor vision, nystagmus (involuntary side to side movements of the eyes) and evidence of abnormal retinal function from infancy. LCA is not a single disorder as the same signs of the condition may be seen with faults in at last 10 different genes; more causative genes remain to be discovered. What is common to all forms of LCA is that the photoreceptors (the light sensitive cells in the retina) do not function normally.
