Optic neuritis is a demyelinating disease of the central nervous system. Besides affecting the optic nerve and causing a decrease in vision, it also impacts the brain's white matter and the spinal cord, leading to symptoms such as limb paralysis, numbness, and bladder and bowel dysfunction. Generally, the recovery period for optic neuritis is about six months, with the first three months being the most critical for recovery. If recovery has not occurred by six months, it is then considered a chronic phase, and further recovery becomes very challenging. It is crucial to diagnose and treat the condition promptly. Treatment primarily involves the use of corticosteroids, immunoglobulins, and potentially B-group vitamins to nourish the nerves. Overall, most patients with optic neuritis can recover substantially; however, the condition is prone to relapse, and the prognosis is poor if it reoccurs.
