Many ocular emergencies are difficult to diagnose in the emergency setting with conventional physical examination tools. Additionally, persistent efforts to re-examine the eye may be deleterious to a patient's overall condition. Ultrasound is an important tool because it affords physicians a rapid, portable, accurate, and dynamic tool for evaluation of a variety of ocular and orbital diseases. The importance of understanding orbital anatomy, with attention to the firm attachment points of the various layers of the eye, cannot be understated. This article describes the relevant eye anatomy, delves into the ultrasound technique, and illustrates a variety of orbital pathologies detectable by bedside ultrasound.
