Filter by: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.
Prospective interventional study on 60 eyes of resistant diabetic macular edema and central retinal vein occlusion that will receive suprachoroidal injection of Triamcinolone Acetonide (SCTA).
This is a prospective, randomized, single-center clinical study aiming to explore the safety and efficacy of venous stenting for patients with internal jugular vein stenosis (IJVS).
Pediatric emergency department (PED) physicians frequently encounter children with symptoms that warrant evaluation of the optic disc for suspected increased intracranial pressure (ICP) such as headache, blurred vision, recurrent vomiting etc. Fundoscopic examination, by the PED physician, is considered an essential modality for assessment of the optic disc and the diagnosis of papilledema. Obtaining good visualization of the optic disc requires patient compliance, the ability to open the eyelids, the absence of opacities in the ocular media and a sufficiently large pupillary aperture. Hence, different levels of PED physician training, lack of cooperation, significant ocular or periorbital trauma, contraindications to mydriasis and severe photophobia may hinder direct fundoscopic evaluation. In the investigators' PED, children requiring fundoscopy are sent to a formal ophthalmologic examination. The investigators aim to evaluate the yield of optic disc height as measured with ocular point of care ultrasound to detect optic disc swelling in comparison to ophthalmologic examination as the gold standard.
