Rapid identification of ophthalmologic emergencies can be challenging in the ED, and a missed or delayed diagnosis may have vision-threatening consequences. The application of ocular point-of-care ultrasound (POCUS) by the emergency physician (EP) can facilitate the timely recognition of a myriad of emergent eye conditions. This report describes a case in which EP-performed POCUS established the prompt diagnosis of a traumatic lens dislocation in a patient with chronic vision changes.
