In: Ophthalmic Imaging: from theory to current practice, Paris, October 4, 2024.http://hdl.handle.net/10400.21/21320Pituitary adenomas (PA) are the most common tumor of the Sella turcica brain region, accounting for 12–15% of symptomatic intracranial brain tumors. Usually occurs in adults with no gender predilections. Using Cranial Tomography (CT) and Magnetic Resonance Imaging (MRI) (Fig.1) is possible to classify it as a macroadenoma when size is ≥10 mm. The tumor compression on the optic nerve or chiasm leads to axonal damage that causes visual field (VF) defects, thinning of the retinal nerve fiber layer (RNFL), and a reduction in the macular ganglion cell complex (GCC) thickness measured by Optical coherence tomography (OCT). We present two clinical cases with different management approaches based on a previous structure-function evaluation.engOrthopticsPituitary macroadenomaOptical coherence tomographyCase reportconference poster
