Generally, eyesight deteriorates over a few days rather than suddenly. The degree of visual impairment experienced with optic neuritis depends on how many nerve fibres are inflamed – the more nerve fibres affected, the worse the symptoms. Inflammation causes affected nerves to swell, which means they cannot work properly. Each nerve plays a significant role in sending information from the retina to the brain. The optic nerve is actually more than one million individual nerves bundled together. Optic neuritis is also known as retrobulbar neuritis. A number of diseases and conditions can trigger this inflammation, including multiple sclerosis. Vision improves by itself in up to 80 per cent of cases, while some degree of reduced vision is permanent for the remaining 20 per cent. Optic neuritis can occur at any age, but people in their 30s are most commonly affected. The symptoms can range from mild to severe, depending on the extent of the inflammation. Optic neuritis is inflammation of the optic nerve that causes blurred, grey and dim vision. Our sight relies on the optic nerve transmitting information on shape, colour and pattern from the back of the eye (retina) to the brain’s visual centres. The optic nerve connects the eye to the brain.
