    Optic neuritis<\/strong> (noun)<\/em>: inflammation of the optic nerve, the cable that carries what you see from the eye to the brain. It usually strikes one eye, most often in adults aged 20 to 45, and causes blurred or dim vision, washed-out colours and pain when the eye moves. Most people recover much of their vision within weeks to months, but optic neuritis can be the first sign of multiple sclerosis (MS), so it needs an urgent eye examination.<\/p>\n\t\t\t

    In short:<\/strong> sudden blurred vision with pain on eye movement needs same-day assessment by an eye doctor where you live. After the first episode, a review of your recovery, scans and next steps can be done by our eye surgeons in Istanbul, including Do\u00e7. Dr. Muhammet Derda \u00d6zer, who sees inflammatory and retinal causes of sight loss.<\/p><\/div>\n\t<\/div><\/div><\/div><\/div><\/section>\n\n\n\n\n

    What is optic neuritis?<\/h2>\n\t\t\t\t\t\t\t\t

    The optic nerve is a bundle of more than a million nerve fibres that leaves the back of each eye and carries signals to the brain. Each fibre is wrapped in myelin, an insulating coat that lets signals travel fast. In optic neuritis, the immune system attacks that coating, the nerve becomes inflamed and swollen, and the signal weakens. That is why vision dims even though the eye itself looks normal.<\/p>\n

    The condition is called demyelinating<\/strong> optic neuritis when it comes from this immune attack. Doctors also separate typical<\/strong> optic neuritis (one eye, pain on movement, steady recovery, often linked to MS) from atypical<\/strong> optic neuritis (both eyes, no pain, severe loss, or no recovery), which needs more tests and different treatment.<\/p><\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/section>\n\n\n\n\n
