Objective: To investigate the relationship between optic nerve sheath diameter (ONSD) and clinical and carboxyhemoglobin levels in patients with carbon monoxide poisoning.
Material And Methods: This prospective cross-sectional study enrolled 55 consecutive adult patients with carbon monoxide poisoning. The demographic and clinical characteristics of the patients and the diameters of the optic nerve sheaths of both eyes of those patients at the time of admission and at the 6th hour after receiving 100% oxygen therapy and/or hyperbaric oxygen therapy were determined.
