Leber's hereditary optic neuropathy (LHON) is a mitochondrial inherited form of vision loss. Although this condition usually begins in a person's teens or twenties, it may appear in early childhood or later in adulthood. For unknown reasons, males are affected more often than females.

Blurring and clouding of central vision are usually the first symptoms of this disorder. These vision problems may begin in one eye or simultaneously in both eyes; if vision loss starts in one eye, the other eye is usually affected within several weeks or months. Over time, central vision in both eyes worsens with a severe loss of sharpness (visual acuity) and often affects colour vision. This condition mainly affects central vision and good peripheral vision usually remains to varying extents.  The loss of central vision creates difficulties for detailed tasks such as reading, driving, and recognizing faces.  Vision loss results from the death of retinal ganglion cells in the nerves that relay visual information from the eyes to the brain. Although central vision gradually improves in a small percentage of cases, in most cases the vision loss is profound and permanent and those affected are legally blind.

Painless central vision loss of is typically the only symptom of Leber's hereditary optic neuropathy; however, some families with other signs and symptoms have been reported.
