Leber Congenital Amaurosis

Leber congenital amaurosis (LCA) is a genetic condition that causes severe loss of vision at birth or early childhood. LCA causes childhood blindness in one of every 33,330 people.

• Symptoms are often noticed in the first weeks or months after a child is born.
• Parents may observe that the child does not focus its eyes on things in his/her environment.
• A child may exhibit rapid, ‘wobbly’ back-and-forth eye movements, called nystagmus.
• Some children may press or push on their eyes with their fingers or fists.

As of today, there are no treatments for LCA, but a number of clinical trials involving gene therapy are currently underway. The Foundation Fighting Blindness funds leading research into LCA and encourages people living with this disease to enrol in the FFB Patient Registry, which will keep you updated on emerging clinical trials and opportunities to participate.
