Leber’s Hereditary Optic Neuropathy

Leber's Hereditary Optic Neuropathy (LHON) is a genetic condition that primarily affects the optic nerve, leading to sudden vision loss, usually in young adults. It is caused by mutations in mitochondrial DNA, which are inherited from the mother. The optic nerve, responsible for transmitting visual information from the eye to the brain, becomes damaged, resulting in decreased vision or blindness. Symptoms can vary, but the loss of central vision is common. While there is no cure, some cases may improve over time, and genetic counseling can provide support for affected families.
