Genetic disorders due to mitochondrial dysfunction are not uncommon and the majority of these patients will have eye-related manifestations, including visual loss from the optic nerve and retinal disease, visual field loss from retrochiasmal visual pathway damage, and ptosis and ocular dysmotility from extraocular muscle involvement.
One of the most common hereditary eye diseases is retinitis pigmentosa, a disease that destroys the light-sensitive cells within the retina.

Leber hereditary optic neuropathy (lhon) is an inherited form of vision loss. Although this condition usually begins in a person's teens or twenties, rare cases may appear in early childhood or later in adulthood. For unknown reasons, males are affected much more often than females. Blurring and clouding of vision are usually the first symptoms of lhon.

Inherited retinal diseases (also called inherited retinal dystrophies, or irds) are a group of rare eye disorders caused by an inherited gene mutation and can result in vision loss or blindness. Some people with inherited retinal diseases, for instance those with retinitis pigmentosa (rp) or choroideremia (chm), experience a gradual loss of vision, eventually leading to complete blindness.

Genes play a highly significant role in eye diseases, some of which are highly prevalent in children and adults. Over 60% of cases of childhood blindness are caused by genetic factors (congenital glaucoma, ocular malformations, atrophy of the optic nerve and retinitis pigmentosa). In adults, genetic factors can also be associated with serious eye diseases, including glaucoma and macular degeneration.
