About

Dr. Chihiro Mayama is a leading researcher in ophthalmic physiology and surgical safety, whose work bridges the critical intersection of intraocular pressure (IOP) dynamics and patient outcomes in minimally invasive procedures. Her most influential study, "Transient but Significant Visual Field Defects after Robot-Assisted Laparoscopic Radical Prostatectomy in Deep Trendelenburg Position" (2015, 60 citations), established a landmark connection between prolonged steep head-down positioning during robotic surgery and acute ocular complications. This research demonstrated that the dramatic IOP elevation induced by the Trendelenburg position can cause transient visual field defects, fundamentally altering perioperative protocols and raising awareness among urological surgeons. Dr. Mayama’s contributions extend to elucidating the mechanisms of IOP regulation under extreme postural conditions, providing essential insights for preventing vision-threatening events in surgical settings. Her work has been widely cited by both ophthalmologists and surgical teams, highlighting its cross-disciplinary impact. By identifying a previously underappreciated risk in robotic-assisted surgery, Dr. Mayama has advanced patient safety standards and inspired further investigations into ocular physiology during non-ophthalmic procedures, solidifying her reputation as a pioneer in surgical ophthalmology.
