Most optic nerve sheath tumors are benign tumors, and their prognosis is closely related to the location of the lesion, the size of the lesion, and the time of treatment. Optic nerve sheath tumor is a kind of nerve sheath tumor. If patients can receive scientific and standardized treatment early, the prognosis is good and will not affect life expectancy. If not treated in time, the tumor may compress the surrounding tissues, resulting in protrusion of the eye, loss of vision, secondary optic papillary atrophy, and optic nerve ciliary vein, which is called optic nerve sheath tumor quadruplex. At present, surgery is recognized as an effective treatment. Receiving surgery at an early stage can avoid tumor invasion of adjacent tissues, which has a good prognosis and can lead to long-term survival; if they fail to receive treatment at an early stage, they have the possibility of blindness and their quality of life will be greatly reduced, which will affect their survival to a certain extent. Therefore, patients with optic nerve sheath tumor should be detected, diagnosed and treated early, and the treatment plan should be specified by ophthalmologists or neurosurgeons in regular hospitals according to their conditions, and most of them have a better prognosis.
