Conventional brain MRI was performed for all patients and evaluated for abnormal findings. We used chi square test for qualitative variables and T-test for quantitative variables Results: Thirty-nine (55.7%) patients with optic neuritis were seen with abnormalities in MRI. In this group, 31 (...
The period for development of MS was significantly shorter in patients with MRI lesions (p < 0.001). Optic neuritis patients with brain MRI findings showing the morphological evidence of disseminated disease can be considered to have MS at the time of the initial ON attack, and disease-modifying...
MRI scan is as well essential for diagnosis of Optic Neuritis. Sometimes, optic neuritis is also tested by some blood tests like ESR test. Treatment for Optic Neuritis Medical care and consultation of ophthalmologist as well as neurologist are very important points in treatment of optic neuritis; ...
s for demonstratingoptic neuritis. The orbital or intracranial portions of the nerve can be involved as can the chiasm. Enhancement withgadoliniumis subtle and often confined to a short segment of the nerve. In 10–20% of initial cases MRI may reveal silent demyelinating lesions in the brain....
Optic neuritis is an inflammatory condition that affects the optic nerve, the nerve responsible for transmitting visual information from the eye to the brain. This inflammation can result in sudden vision loss, typically in one eye, accompanied by pain, especially during eye movement. While optic ...
Approximately 15-20% of cases of definite multiple sclerosis present with optic neuritis; another 40% will suffer an attack at some point. When optic neuritis occurs without antecedent signs of multiple sclerosis, magnetic resonance imaging (MRI) of the brain frequently reveals characteristic signal ...
Optic neuritis (ON), an inflammatory optic neuropathy, is among the most common causes of visual loss. In its initial clinical appearance, ON may have unil
The Optic Neuritis Treatment Trial (ONTT) has helped stratify the risk of developing multiple sclerosis after the first episode of optic neuritis based on abnormal findings on brain MRI. The ONTT also demonstrated that while initial treatment of optic neuritis with intravenous corticosteroids followed...

Since optic neuritis can be confused with many other causes of poor vision, an accurate medical diagnosis is important: Other tests which may be performed include color vision, visual field, the reaction of the pupil to light, and MRI scanning. If a cause can be found and treated, further ...
