Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy.
Behr syndrome is characterized by the association of early-onset optic atrophy with spinocerebellar degeneration resulting in ataxia, pyramidal signs, peripheral neuropathy and developmental delay. [1] [2] Although it is an autosomal recessive disorder, heterozygotes may still manifest much attenuated symptoms. [3]
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 adult males, and onset is more likely in younger adults.
The American study found that Ozempic more than doubles the risk of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition that damages the optic nerve.
Dominant optic atrophy was first described clinically by Batten in 1896 and named Kjer’s optic neuropathy in 1959 after Danish ophthalmologist Poul Kjer, who studied 19 families with the disease. [3] Although dominant optic atrophy is the most common autosomally inherited optic neuropathy (i.e., disease of the optic nerves), it is often ...
Between 1992 and 1993, in the Cuban Epidemic of Optic Neuropathy, nearly 50,000 people in Cuba were affected with optic neuropathy, sensory and autonomic peripheral neuropathy, neural deafness, and in a few cases, myelopathy. [15] [16] The most common pattern of symptoms consisted of severe weight loss, fatigue and a subacute loss of vision.
Optic nerve hypoplasia (ONH) is a congenital condition in which the optic nerve is underdeveloped (small). Many times, de Morsier’s Syndrome or septo-optic dysplasia (SOD) is associated with ONH, however, it is possible to have ONH without any additional issues like SOD.
He does indeed turn out to be a carrier, giving their unborn child a 25% chance of having LCA. [citation needed] In the television series ER (Season 14, Episode 12 "Believe the Unseen") Dr. Abby Lockhart diagnoses a young foster girl with Leber congenital amaurosis. The girl to this point hid her condition from her foster families.
