Evaluation of Early Retinal Vascular Modifications After Endoscopic Endonasal Pituitary Surgery

Early Retinal Vascular Modifications After Endoscopic Endonasal Pituitary Surgery: The Role of OCT- Angiography

This study evaluates the retinal vascular features using optical coherence tomography angiography in patients that received endoscopic endonasal approach for the removal of an intra-suprasellar pituitary adenoma compressing the optic nerve.

To investigate the potential role of optical coherence tomography angiography in predicting the postoperative recovery of retinal vascular network of the optic disc in patients before and at 3 months after Endoscopic Endonasal Approach for the removal of an intra-suprasellar pituitary adenoma compressing the optic nerve.

The optical coherence tomography angiography represents a novel and non-invasive diagnostic technique that allows a detailed analysis of retinal vascular features.
