Short answer · Medically reviewed summary · Last updated: 2023-07-13
Leber Congenital Amaurosis (LCA) is a rare inherited eye disorder that primarily affects the retina, leading to severe visual impairment or blindness from birth or early infancy. LCA is estimated to have a prevalence of approximately 1 in 50,000 to 1 in 100,000 individuals worldwide. Prevalence: LCA is considered to be one of the most common causes of congenital blindness in children. It affects both males and females equally. The prevalence may vary among different populations and ethnicities. Due to its rarity, LCA is classified as an orphan disease. Although LCA is a relatively uncommon condition, its impact on affected individuals and their families is significant.

- It affects both males and females equally.
- The prevalence may vary among different populations and ethnicities.
- Due to its rarity, LCA is classified as an orphan disease.
Although LCA is a relatively uncommon condition, its impact on affected individuals and their families is significant. The severity of visual impairment can vary, with some individuals experiencing only light perception or limited visual acuity, while others may have complete blindness. Ongoing research and advancements in genetic testing have improved the understanding and diagnosis of LCA, leading to potential treatment options such as gene therapy.
