If the [[ophthalmic artery aneurysm]] continues to enlarge then an upward displacement of the [[optic nerve]] against the [[falciform ligament]] produce a [[monocular inferior nasal quadrantanopsia]] by superior temporal fiber compression. Compression of the [[optic nerve]] near the [[chiasm]] may also produce a superior temporal quadrant defect in the contralateral eye ([[junctional scotoma]] "pie in the sky" defect) from injury to the anterior [[Wilbrand's knee]]. visual_field_defect_from_ophthalmic_artery_aneurysm.txt Last modified: 2024/06/07 02:51by 127.0.0.1
