Optic neuroma is generally due to family inheritance, abnormal cell proliferation, long-term stimulation by external cancer-causing factors and other factors. 1. Family heredity: family heredity refers to the disease controlled by disease-causing genes, and it is hereditary in nature, which will cause optic neuroma, optic disk edema, gradual vision loss and other symptoms. 2. Abnormal cell proliferation: abnormal cell proliferation refers to the abnormal proliferation of optic nerve glial cells, which gradually spreads and leads to the formation of optic neuroma, which may cause headache, dizziness and other symptoms. 3. Long-term stimulation by external cancer-causing factors: long-term stimulation by external cancer-causing factors means that normal cells of the body are stimulated by cancer-causing factors for a long period of time, which will lead to cancerous transformation of normal cells, thus leading to the formation of optic neuroma, and the symptoms of visual field loss and blurred vision will appear. If you are suffering from optic nerve tumor, consult a doctor in time to clarify the cause of the disease and treat it actively.
