Frequency. can be relapsing. Optic neuritis describes any condition that causes inflammation of the optic nerve; it may be associated with demyelinating diseases, or infectious or inflammatory processes. [ 1 ] It is also known as optic papillitis (when the head of the optic nerve is involved), neuroretinitis (when there is a combined ...
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. The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye.
Photopsia is the presence of perceived flashes of light in the field of vision. It is most commonly associated with: [4] Vitreous shrinkage or liquefaction, which is the most common cause of photopsia, causes a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses.
Neurology. Symptoms. Shooting pain, numbness, tingling, tremors, bladder problems, unsteadiness. Peripheral neuropathy, often shortened to neuropathy, refers to damage or disease affecting the nerves. [ 1 ] Damage to nerves may impair sensation, movement, gland function, and/or organ function depending on which nerve fibers are affected.
Specialty. Ophthalmology, optometry. Anterior ischemic optic neuropathy (AION) is a medical condition involving loss of vision caused by damage to the anterior portion of the optic nerve as a result of insufficient blood supply (ischemia). This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION ...
Frequency. Up to 1 in 10,000 [ 1 ] 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.
Optic papillitis is a specific type of optic neuritis. Inflammation of the optic nerve head is called "papillitis" or "intraocular optic neuritis"; inflammation of the orbital portion of the nerve is called "retrobulbar optic neuritis" or "orbital optic neuritis". [ 1 ] It is often associated with substantial losses in visual fields, pain on ...
Neuritis (/ njʊəˈraɪtɪs /), from the Greek νεῦρον), [1] is inflammation of a nerve [2] or the general inflammation of the peripheral nervous system. Inflammation, and frequently concomitant demyelination, [3][4][5] cause impaired transmission of neural signals and leads to aberrant nerve function. Neuritis is often conflated with ...
