Our study aims to assess ICP in sICH patients by measuring the optic nerve sheath diameter (ONSD) via ultrasound, and to explore whether prehospital ONSD measurement as a surrogate for ICP is associated with the clinical prognosis and imaging outcomes of sICH patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This prospective study enrolled adult patients diagnosed with sICH upon emergency admission via prehospital care between January 2025 and December 2025. Ultrasound measurements of the ONSD were recorded at initial prehospital contact, post-departure in the ambulance, and upon hospital arrival. An ONSD \u22655\u202fmm was defined as elevated ICP. We compared the in-hospital mortality rate, the proportion of early neurological deterioration (END), and the extent of hematoma expansion on imaging between the elevated ICP group and the normal ICP group. Regression analysis after adjusting for confounding factors was used to explore the relationship between ONSD and in-hospital mortality, END, and the extent of hematoma expansion on imaging in patients with sICH. Kaplan\u2013Meier curves were used to analyze the survival probabilities of the two groups (ONSD \u22655\u202fmm vs. ONSD &amp;lt; 5\u202fmm).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 186 patients were enrolled in this study, with a mean age of 62.8\u202f\u00b1\u202f11.4\u202fyears. Among them, 112 patients (60.2%) were male. The ONSD \u2265 5\u202fmm group had significantly higher rates of in-hospital mortality, END, and hematoma expansion compared to the ONSD &amp;lt; 5\u202fmm group (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
