The microscopic and endoscopic techniques provide similar outcomes in the surgical treatment of Knosp Grades 0-2 nonfunctioning pituitary macroadenomas 1).

Stratified preoperative peripapillary retinal nerve fiber layer (pRNFL) and ganglion cell-inner plexiform layer (GCIPL) thicknesses measured via optical coherence tomography (OCT) in different age categories are effective biomarkers for predicting visual functional outcomes after decompression of pituitary tumors 2).
