Ocular PoCUS

EM Ottawa - August 18, 2022 - By Joyes Botros, Wilson Lam, Rajiv Thavanathan
Summary
POCUS can be a useful adjunct to the eye exam when seeing a patient with visual disturbances in the emergency department. It can be useful in detecting increased optic nerve sheath diameter and optic disc elevation suggestive of increased intracranial pressure. It may also be useful in seeing a thick or thin hyperechoic membrane which may suggest retinal detachment or vitreous detachment, respectively. In patients with vitreous hemorrhage, you may see a washing machine sign. Finally, look out for the retrobulbar spot sign indicative of central retinal artery occlusion. On your next shift, try using POCUS to help you gain more information to integrate into your clinical case and help you diagnose your ocular emergencies.
