PoCUS for Retinal Detachment

Jacobsen B et al. West J Emerg Med 2016; 17(2):196-200.

Retinal detachment is an ocular emergency that commonly presents to the emergency department (ED). Ophthalmologists are able to accurately make this diagnosis with a dilated fundoscopic exam, scleral depression or ophthalmic ultrasound when a view to the retina is obstructed. Emergency physicians (EPs) are not trained to examine the peripheral retina, and thus ophthalmic ultrasound can be used to aid in diagnosis. We assessed the accuracy of ocular point-of-care ultrasound (PoCUS) in diagnosing retinal detachment. 
We enrolled a total of 109 patients. Of the 34 patients diagnosed with retinal detachment by the ophthalmologists, 31 were correctly identified as having retinal detachment by the EP using ocular PoCUS. Of the 75 patients who did not have retinal detachment, 72 were ruled out by ocular PoCUS by the EP. This resulted in a PoCUS sensitivity of 91% (95% CI [76-98]) and specificity of 96% (95% CI [89-99]). 
This retrospective study suggests that ocular PoCUS performed by EPs can aid in the diagnosis of retinal detachment in ED."
