Optic Neuritis
Optic neuritis is a condition where the optic nerve gets inflamed. Due to the inflammation, light and visual images are not clearly transmitted to the brain. Optic neuritis can be caused by autoimmune diseases such as multiple sclerosis or viral infections such as chicken pox or measles. Optic neuritis is usually the first sign of multiple sclerosis. This condition tends to affect more women than men.
Patients suffering from optic neuritis notice reduced vision. This is more so when the body temperature is elevated. The eyes are sore and painful when moved. There is reduced color perception and diminished peripheral vision. Persons suffering from optic neuritis may have headache and fever. The vision diminishes for about a week and then gradual improvement is noticed. Typically most patients suffering from optic neuritis tend to recover most of their vision within about 6 months.
The opthalmologist will test the patient's color vision and visual field. Eye presure and pupillary function will be examined. The optic disc is viewed with indirect ophthalmoscopy. Brain MRI may be taken for testing for multiple sclerosis. Intravenous steroid medication has shown results on those suffering from initial occurence of optic neuritis.
