Health Guide: A patient in his sixties has been suffering from a continuous decline in vision in the last two years. She guessed that it was a common cataract in the elderly, so she went to the eye hospital to remove the cataract. Unexpectedly, her eyesight became worse and worse after the operation. Later, she was diagnosed as a tumor, which led to it. After surgical resection of the tumor, the patient's vision improved and basically returned to normal after a period of time.

Most tumors are pituitary tumors. Because the optic nerve just passes through the pituitary gland, pituitary adenoma grows up gradually, which will compress the optic nerve and damage vision. Visual field disturbance is one of its main symptoms. If the oppression of the optic nerve is not relieved for a long time, it will cause optic nerve atrophy and serious blindness. See a doctor after blindness. Although the brain tumor can be surgically removed, the possibility of vision recovery is very small. Clinical observation shows that the occurrence of brain tumor is closely related to human vision, and tumors in brain, cerebellum and ventricle can all invade the optic nerve.

The symptoms caused by brain tumor have three characteristics: first, there is no abnormality in the appearance of eyes, but the vision is obviously reduced; Second, vision loss is often accompanied by visual field defect, that is, the range that the eyes can see is reduced; Third, examination of the fundus can reveal edema or atrophy of the optic nerve.

Blurred vision is not necessarily a cataract, but a pituitary tumor. Be sure to go to a regular hospital for a check-up so as not to delay your illness.
