About

Dr. Marcus H. Colyer is a leading ophthalmologist and researcher whose work bridges surgical innovation and patient safety, with a particular focus on ischemic optic neuropathy (ION) and the ocular complications of systemic procedures. His landmark 2007 study, "Posterior Ischemic Optic Neuropathy After Minimally Invasive Prostatectomy" (174 citations), was the first to document ION following laparoscopic and robot-assisted prostatectomy, fundamentally altering perioperative risk assessment for these increasingly common surgeries. By identifying how prolonged Trendelenburg positioning and elevated intraocular pressure during minimally invasive procedures could trigger devastating vision loss, Colyer established critical safety protocols now adopted in operating rooms worldwide. His research has profoundly impacted the fields of urology, anesthesiology, and ophthalmology, demonstrating how seemingly remote surgical techniques can threaten ocular perfusion. Beyond this seminal work, Colyer has contributed extensively to retinal disease management, diabetic retinopathy, and ocular trauma, particularly in military and combat settings. His investigations into the pathophysiology of posterior ION have saved countless patients from preventable blindness, cementing his reputation as a clinician-scientist who transforms surgical complications into opportunities for safer practice.
