8.7% global prevalence in 2020 [ 2] 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 ...
Neuromyelitis optica spectrum disorders ( NMOSD) are a spectrum of autoimmune diseases characterized by acute inflammation of the optic nerve ( optic neuritis, ON) and the spinal cord ( myelitis ). [1] [2] [3] Episodes of ON and myelitis can be simultaneous or successive. A relapsing disease course is common, especially in untreated patients.
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, as it is primarily due ...

It is located above the brain stem, posterior to the brain. Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration, and alcoholic or nutritional cerebellar ...
Choroidal neovascularization ( CNV) is the creation of new blood vessels in the choroid layer of the eye. Choroidal neovascularization is a common cause of neovascular degenerative maculopathy (i.e. 'wet' macular degeneration) [ 1] commonly exacerbated by extreme myopia, malignant myopic degeneration, or age-related developments.
Pellucid marginal degeneration ( PMD) is a degenerative corneal condition, often confused with keratoconus. It typically presents with painless vision loss affecting both eyes. Rarely, it may cause acute vision loss with severe pain due to perforation of the cornea. It is typically characterized by a clear, bilateral thinning ( ectasia) in the ...
Genetic. Diagnostic method. Slit lamp. Treatment. None. 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).
