The frequency of occurrence after operations performed in the prone position, such as lumbar discectomy, can be up to 4 times that of other surgeries. Although the most common cause is reported as posterior ischemic optic neuropathy, increased intraocular pressure from the prone position may also be a cause. In our study, it was investigated whether general and spinal anesthesia would have different effects on intraocular pressure in lumbar discectomies performed in the prone position. Following approval of Local Ethics Committee, Patients aged 18-65 years, ASA1-2 risk group who were scheduled for lumbar disc hernia surgery under elective conditions were included in the study and divided into Group GA (General Anesthesia) and Group SA (Spinal Anesthesia). Demographic and operative data of the patients were recorded. Intraocular pressure measurements were performed in the preoperative supine position and It was measured at the 5th minute of the supine position after the postoperative prone position. 120 patients were included in the study, data of 77 patients were analyzed. In Group GA, postoperative intraocular pressure values increased compared to the values obtained preoperatively (p <0.001 for both eyes); Pre- and postoperative intraocular pressure values were found to be similar in Group SA (p=0.727 and 0.699). A sudden increase in arterial blood pressure and heart rate values was observed in GroupGA with extubation. In the regression analysis examining demographic data and intraoperative measurements, a linear relationship was found between only body mass index and both intraocular pressure values. In our study, disc herniation operations lasting less than 2 hours, with stable hemodynamics, were examined. It was determined that the intraocular pressure increased significantly after general anesthesia and did not change after spinal anesthesia. If there is concern about an increase in intraocular pressure during the intraoperative period, we believe that spinal anesthesia should be preferred. This recommendation is for lumbar discectomy cases where hemodynamics is minimally affected and bleeding is not expected. It should be considered that this increase may be higher in patients with a high body mass index.}, number={3}, publisher={İstanbul Aydın Üniversitesi}
