The study evaluated the effect of ONSD on intracranial pressure (ICP) and neurological recovery after DC and determined the prognostic value of this measurement.<\/jats:p>\n<\/jats:sec>\n\nMethods: <\/jats:title>\nThis study was conducted on 54 patients who underwent DC for cerebral infarction between 2018 and 2024 at a tertiary university hospital, Atat\u00fcrk university faculty of medicine. Demographic data (age, gender), clinical data (preoperative and postoperative Glasgow Coma Scale [GCS] scores, Glasgow Outcome Scale [GOS] scores), and ONSD measurements were obtained from patient records. ONSD measurements were taken at preoperative 1 h, postoperative 1 h, postoperative 24 h, and postoperative 72 h. Measurements were performed with an ultrasound probe on both eyes while patients were in a supine position with their eyes closed. Patients were divided into two groups based on their GCS scores: Group 1 (GCS > 8) and Group 2 (GCS \u2264 8). Statistical analyses of the data were performed using Student\u2019s t<\/jats:italic>-test and Mann\u2013Whitney U-test, with P<\/jats:italic> < 0.05 considered statistically significant.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nGroup 1 consisted of 26 patients (mean age 67.2 \u00b1 6.4 years), and Group 2 consisted of 28 patients (mean age 72.4 \u00b1 5.8 years) (P<\/jats:italic> = 0.019). Preoperative ONSD was significantly wider in Group 2 (6.3 \u00b1 0.5 mm) compared to Group 1 (5.2 \u00b1 0.4 mm) (P<\/jats:italic> \u2248 0). Postoperative 1-h ONSD values were also significantly wider in Group 2 (6.0 \u00b1 0.6 mm) compared to Group 1 (4.8 \u00b1 0.5 mm) (P<\/jats:italic> \u2248 0). At 24 and 72 h, ONSD values in Group 2 remained significantly wider compared to Group 1. GOS scores were lower in Group 2 (2.1 \u00b1 0.9) compared to Group 1 (3.2 \u00b1 0.8) (P<\/jats:italic> \u2248 0). There was a strong negative correlation between ONSD measurements and GOS scores.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nONSD is an important non-invasive indicator in the assessment of ICP and clinical outcomes. High ONSD values are associated with poor clinical outcomes, and a reduction in postoperative ONSD reflects the success of surgical intervention. ONSD measurements can be used as a prognostic tool in clinical practice and play a crucial role in the management and monitoring of patients with high ICP. It is recommended that these findings be validated in larger patient groups and different clinical scenarios.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_327_2025","type":"journal-article","created":{"date-parts":[[2025,5,16]],"date-time":"2025-05-16T11:01:39Z","timestamp":1747393299000},"page":"184","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The
