Pituitary tumor causing visual field change needs to be treated by surgery, medication, radiotherapy and general measures. 1. Surgical treatment: the change of visual field caused by pituitary tumor is mostly considered to be caused by the compression of optic nerve by pituitary tumor with too large volume, and the patients can follow the doctor’s instruction to take surgical treatment such as transfrontal surgery and transnasal butterfly microsurgery. 2. Drug therapy: some patients with pituitary tumor can be treated with drugs under the guidance of doctors, such as bromocriptine, octreotide and so on. 3. Radiation therapy: For patients with pituitary tumors causing visual field changes, but cannot undergo total surgery or have contraindications to surgery, conventional radiation therapy or stereotactic radiation therapy can be adopted. 4. General measures: patients with pituitary tumor who have visual field changes should ensure enough rest, avoid overwork, pay attention to keep warm and avoid getting cold. In addition, they should quit smoking and limit alcohol, and eat foods rich in vitamins and proteins such as kiwifruit, tomato, lean meat, fish and so on. It is recommended that pituitary tumor patients with visual field changes need to consult a doctor in a timely manner, under the guidance of the doctor’s active treatment.
