NCT ID: NCT02643615 Active, not recruiting - Clinical trials for Ischemic Optic Neuropathy

Safety and Efficacy of Using SightSaver Visual Evoked Potential (VEP) for VEP Monitoring in Prone Spine Surgery

SightSaver
Start date: September 2014
Phase: N/A
Study type: Interventional

Post-operative visual loss (POVL) following non-ocular surgical procedures is an infrequent but severe complication. Little is understood about this complication, but most cases seem to result from loss of blood flow to the optic nerve. This is a pilot, single center, prospective, randomized, two-arm study involving 20 subjects at The Ohio State University Wexner Medical Center who are scheduled to undergo spine surgery that requires prone position and at least two hours of general anesthesia or total intravenous anesthesia (TIVA) and intraoperative neurophysiological monitoring. Patients will be randomized to either general anesthesia or TIVA, and wear the SightSaver device to monitor visual evoked potentials (VEPs) during surgery in order to detect possible changes in optic nerve function that may lead to POVL. We hypothesize that this new, flexible, disposable device will yield better results and more patient satisfaction than devices currently used for visual monitoring during prone spine surgeries.

NCT ID: NCT00000126 Active, not recruiting - Clinical trials for Ischemic Optic Neuropathy

Ischemic Optic Neuropathy Decompression Trial Followup (IONDT Followup)

Start date: October 1994
Phase: N/A
Study type: Observational

To follow all patients enrolled in the original Ischemic Optic Neuropathy Decompression Trial (IONDT) to determine (1) the incidence of non-arteritic ischemic optic neuropathy (NAION) in the second eye, (2) changes in visual acuity over time in both the study and second eye, and (3) other aspects of the natural history of NAION.
