The most common tumors of the optic nerve include gliomas and meningiomas, according to Patient.co.uk. Both conditions are associated with a gradual, painless fogginess and dimming eyesight. Another usually benign tumor is the melanocytoma, which grows very slowly. Symptoms of melanocytoma are caused by expansion of the tumor and subsequent pressure on adjacent structures rather than malignant growth. Other brain tumors can also affect the optic nerve indirectly by compression.
