Discrepancy between structural and functional visual recovery in patients after trans-sphenoidal pituitary adenoma resection

Pituitary adenoma (PA) is one of the most common brain tumor types, accounting for 15% of all intracranial neoplasms [1]. Visual disturbances are noted when the tumor grows beyond the sellae and compresses the optic chiasm. Recovery has been attributed to resolution of compression, redistribution of ion channels along the demyelinated membrane, and subsequent remyelination [2,3]. Neural plasticity has also been suggested to be involved in the recovery of these visual disturbances.
