Optic neuropathy is a condition caused by the damage or degradation of the optic nerve. This condition negatively affects vision because it interferes with the normal way that you interpret visual images, causing changes in vision like blurriness, dullness . The study is created by eHealthMe and uses data from the Food and Drug Administration (FDA). Leber hereditary optic neuropathy (LHON) is a condition characterized by vision loss. Leber Hereditary Optic Neuropathy (LHON) is the most common inherited mitochondrial disorder and typically affects young males. Vision loss is painless and progressive, mostly affecting central vision and occurring in both eyes simultaneously. This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION), in which the loss of vision is the result of an inflammatory disease of arteries in the head called temporal . It typically begins as a unilateral progressive optic neuropathy with sequential involvement of the fellow eye months to years later. Blurring and clouding of vision are usually the first symptoms . Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common nonglaucomatous optic nerve disorder in patients older than 50 years, although any age group may be affected. (3) Among the factors that provoke optic neuritis, the most common inflammatory processes affected are the orbit, the eyeball, and the brain; infectious processes in the . LHON was the first disease to be associated with mitochondrial DNA point mutations and is, therefore, maternally inherited. Your brain then turns these signals into the images you see. ON can flare up due to an infection or nerve condition. Some families with additional signs and symptoms have been reported and are said to have "LHON plus", a condition which includes vision loss, tremors, and abnormalities of the electrical signals that control the heartbeat (cardiac conduction defects). The pathogenesis of GON has been hypothesized, to either originate from compromised mechanical conditions at the lamina cribrosa or as associated with pathological vascular involvement. This eye problem has several underlying causes. AAIONArteritic Anterior Ischemic Optic Neuropathy. Vision symptoms from optic neuritis can include blurring, blind spots or complete loss of vision. However, some indications in the history can be suggestive. When these nerves get damaged, the protective outer layer or myelin sheath becomes thinner and it is then called optic neuropathy. ON may occur with or without inflammation of the arteries (arteritis) with symptoms. Leber hereditary optic neuropathy (LHON), or sudden vision loss, is an inherited form of vision loss. For example, sometimes visual loss is very gradual, other times a patient wakes up one day and suddenly can't see. These should be treated in order to slow or stop the progression of optic nerve damage. In many cases, only one eye is affected and patients may not be aw Compressive Optic Neuropathy - Any injury caused to the optic neuron by an external lesion, which affects the bunch of nerve fibres extending from optic globe to the optic chiasm, is known as Compressive Optic Neuropathy. Your brain then turns these signals into the images you see. Neuropathy, or nerve damage, can result from a wide range of conditions such as diabetes and even treatments like chemotherapy.

The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye. Sometimes it impacts color vision, where colors start to seem less bright or washed out. 1 Most have both loss of central acuity and a visual field (VF) defect, although VF . The pathogenesis of GON has been hypothesized, to either originate from compromised mechanical conditions at the lamina cribrosa or as associated with pathological vascular involvement. Dominant optic atrophy, or dominant optic atrophy, Kjer's type, is an autosomally inherited disease that affects the optic nerves, causing reduced visual acuity and blindness beginning in childhood.
