Eye

Point-of-care ocular ultrasound can be used to rapidly identify potential vision-threatening ocular emergencies in the emergency department [1]. Because the globe is a fluid-filled structure, it provides a perfect medium for ultrasonography. Direct visualization of the anterior and posterior chambers of the globe, as well adjacent structures, are easily identified with ultrasonography, even when the eyelids are swollen shut. Ocular ultrasound is a safe, non-invasive and well-tolerated adjunct to the physical eye exam that can be performed quickly at the bedside. It is a valuable tool that can be used to evaluate various ocular emergencies including retinal detachment [2], vitreous hemorrhage, lens subluxation, globe rupture, intraocular foreign bodies [3], and elevated intracranial pressure [4].
