The approach to recovery of vision after pituitary tumor surgery must be judged on a case-by-case basis. If the pituitary tumor compresses the optic cross, or optic nerve, for too long, there is no way to restore vision, especially if it was already blind before the surgery, and it is unlikely that vision will return to normal after the surgery. For some patients who underwent pituitary tumor surgery at an early stage, there is still hope for recovery at a later stage. First of all, treatment can be carried out through medication. The most commonly used and best neurotrophic drug is Rat Nerve Growth Factor, which is relatively expensive, but has good efficacy. If long-term oral nutritional drugs are taken, methylcobalamin and vitamin B1 can be taken orally in combination, and only after six months of observation can we decide whether vision can be restored. If in some cases the optic nerve is indeed damaged, there is no way to repair it later.
