Will I get my vision back after removing a pituitary tumor?
What to expect. For our patients with vision loss from pituitary adenoma, meningioma or craniopharyngioma, vision has been restored or improved in 75-80% of cases. Full recovery may occur within a few days of surgery but in some cases, improvement occurs slowly over 6-12 months post-surgery.
Can a tumor affect your vision?

Depending on the size and location of a tumor, abnormal eye movements and other vision changes like seeing floating spots or shapes knows as an “aura” may result.
What kind of tumor affects vision?
Optic nerve gliomas, also called optic gliomas or juvenile pilocytic astrocytomas, tend to be slow growing, low-grade brain tumors that grow on the nerves responsible for carrying vision signals to the brain.
Can a tumor cause double vision?
Difficulty swallowing, facial weakness or numbness, or double vision is a symptom of a tumor in the brain stem. Vision changes, including loss of part of the vision or double vision can be from a tumor in the temporal lobe, occipital lobe, or brain stem.
Can pituitary adenoma cause double vision?
Small tumors of the pituitary are very common and usually without symptoms, unless the tumor produces a hormone. However if the tumor enlarges, it can cause hormonal deficiencies by pressing on the normal pituitary cells. If it grows even larger (> 1 centimeter), it can cause visual loss or double vision.
Can an eye doctor see a tumor?

What causes vision loss after pituitary surgery?
Background: Delayed visual deterioration after pituitary surgery has been attributed to secondary empty sella syndrome and downward herniation of the optic nerves and chiasm, but the pathophysiological basis of this condition is still a matter of debate.
Can you go blind from pituitary surgery?
Although blindness following pituitary apoplexy is rare, visual acuity improves in most patients following transsphenoidal surgery. Early surgery within the first week after ictus leads to excellent visual outcome when compared with surgery that is performed at a later stage.
