Summary

This prospective observational study investigates the potential of point-of-care ultrasonography of the optic nerve sheath diameter (ONSD) to rule out papilledema in patients with suspected hypertensive emergency. The primary focus is on assessing ONSD sensitivity in identifying papilledema (hypertensive retinopathy grade 4), while secondary endpoints include hypertensive retinopathy grade 3, hypertensive encephalopathy, and the need for intravenous rapid-acting medications to lower elevated blood pressure. This study aims to determine the diagnostic characteristics of this procedure for the diagnosis of hypertensive retinopathy, thus assessing its potential as a screening tool to rule out hypertensive retinopathy by the acute internal medicine doctor.
