A Prospective Observational Study on Factors Affecting Optic Nerve Sheath Diameter and Visual Acuity in Prone Spinal Surgery

NCT07395115 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 65

Last updated 2026-02-09

No results posted yet for this study

Summary

The prone position in spinal surgery can alter intracranial pressure and optic nerve sheath diameter (ONSD) and potentially lead to visual complications. This prospective observational study aimed to identify factors influencing ultrasonographic ONSD changes and visual acuity in patients undergoing spinal surgery.
