Whether or not vision can be restored after treatment for a pituitary tumor must be viewed specifically based on the particular condition. Because pituitary tumors are tumor tissue, once they grow particularly large, they can compress the optic cross and cause vision impairment. If the patient’s vision is impaired or even blind before the surgery, there is basically no way to recover it at a later stage. However, if the pituitary tumor grows fast and is treated immediately after the onset of symptoms, the compression can be relieved within a short period of time to reduce the degree of nerve necrosis, and there is a great hope for recovery in the later stages. In the later stage, it is also necessary to actively nourish the nerves, improve the circulation and other treatment measures together, and still can save part of the nerve function. Therefore, if the pituitary tumor reaches a level that affects the vision, it is necessary to carry out appropriate treatment in time, and early treatment is possible to get a better prognosis.
