Optic neuritis is an inflammation that affects the myelin sheath of the optic nerve, limiting its ability to transmit visual signals to the brain. Although the disease can sometimes recover completely after a period of time, active examination and proper monitoring from the beginning is necessary to prevent complications of optic neuritis.

Endoscopic optic nerve decompression surgery is a method used to treat cases of reduced or lost vision after traumatic compression of the optic nerve (cranial nerve number 2).
