1:30,000 to 1:50,000. Leber's hereditary optic neuropathy ( LHON) is a mitochondrially inherited (transmitted from mother to offspring) degeneration of retinal ganglion cells (RGCs) and their axons that leads to an acute or subacute loss of central vision; it predominantly affects young adult males. LHON is transmitted only through the mother ...
Retinoschisis is an eye disease characterized by the abnormal splitting of the retina's neurosensory layers, usually in the outer plexiform layer.Retinoschisis can be divided into degenerative forms which are very common and almost exclusively involve the peripheral retina and hereditary forms which are rare and involve the central retina and sometimes the peripheral retina.
Macular degeneration, also known as age-related macular degeneration ( AMD or ARMD ), is a medical condition which may result in blurred or no vision in the center of the visual field. [1] Early on there are often no symptoms. [1] Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. [1]
1 in 4,000 people [1] Retinitis pigmentosa ( RP) is a genetic disorder of the eyes that causes loss of vision. [1] Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). [1] As peripheral vision worsens, people may experience "tunnel vision". [1] Complete blindness is uncommon. [2]
Retinal degeneration is a retinopathy which consists in the deterioration of the retina [1] caused by the progressive death of its cells. [2] There are several reasons for retinal degeneration, including artery or vein occlusion, diabetic retinopathy, R.L.F./R.O.P. ( retrolental fibroplasia / retinopathy of prematurity ), or disease (usually ...
Dominant optic atrophy (DOA), or autosomal dominant optic atrophy (ADOA), (Kjer's type) is an autosomally inherited disease that affects the optic nerves, causing reduced visual acuity and blindness beginning in childhood. However, the disease can seem to re-present a second time with further vision loss due to the early onset of presbyopia ...
Stargardt disease is the most common inherited single-gene retinal disease. [1] In terms of the first description of the disease, [2] it follows an autosomal recessive inheritance pattern, which has been later linked to bi-allelic ABCA4 gene variants (STGD1).
1 in 40,000 newborns [1] Leber congenital amaurosis ( LCA) is a rare inherited eye disease that appears at birth or in the first few months of life. [2] It affects about 1 in 40,000 newborns. [1] LCA was first described by Theodor Leber in the 19th century. [3] [4] It should not be confused with Leber's hereditary optic neuropathy, which is a ...
