Predictive OCTA Biomarkers After Endoscopic Endonasal Pituitary Surgery
Predictive OCTA Biomarkers After Endoscopic Endonasal Pituitary Surgery
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.
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.
