The primary outcome was to detect the changes in visual acuity, retinal structural and vascular features at 48 hours and 1 year after Endoscopic Endonasal Approach for the removal of an intra-suprasellar pituitary adenoma compressing the optic nerve.~The secondary outcome was to identify potential biomarker that could predict the functional recovery at 1 year follow up.
This study evaluates the structural parameters, by spectral domain optical coherence tomography (OCT), retinal vessel density, using OCT angiography, and visual acuity in patients that received endoscopic endonasal approach for the removal of an intra-suprasellar pituitary adenoma compressing the optic nerve.
