Mitochondrial Disorders
Leber hereditary optic neuropathy (LHON)
Leber hereditary optic neuropathy can cause progressive vision loss in both eyes. Some people also have heart problems or muscle symptoms (such as involuntary muscle contractions, muscle weakness, or muscle spasms). The disorder is more common among men, and symptoms often begin when people are in their 20s or 30s. No treatments are available. However, limiting the consumption of alcohol, which may affect the mitochondria, and not using tobacco products may slow the progression of symptoms. A drug that is injected directly into the space at the back of the eye is currently being studied.
