The microscopic and endoscopic techniques provide similar outcomes in the surgical treatment of Knosp Grades 0-2 nonfunctioning pituitary macroadenomas ((Dallapiazza R, Bond AE, Grober Y, Louis RG, Payne SC, Oldfield EH, Jane JA Jr. Retrospective analysis of a concurrent series of microscopic versus endoscopic transsphenoidal surgeries for Knosp Grades 0-2 nonfunctioning pituitary macroadenomas at a single institution. J Neurosurg. 2014 Sep;121(3):511-7. doi: 10.3171/2014.6.JNS131321. Epub 2014 Jul 4. PubMed PMID: 24995783. )). ---- 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 [[biomarker]]s for predicting visual functional outcomes after [[decompression]] of [[pituitary tumor]]s ((Lee GI, Park KA, Lee D, Oh SY, Kong DS, Hong SD. Predicting visual outcomes after decompression of pituitary tumours based on stratified inner-retinal layer thickness and age. Acta Ophthalmol. 2022 Nov 18. doi: 10.1111/aos.15281.
