Point-of-care Ultrasound to Distinguish Retinal Detachment and Ruptured Arterial Microaneurysm

CASE PRESENTATION: We present the case of an older male with point-of-care-ultrasound (POCUS) imaging consistent with retinal detachment who was instead found by ophthalmology to have a ruptured arterial microaneurysm with vitreous and preretinal hemorrhage. The patient later had complete resolution of his symptoms. We discuss this retinal detachment “mimic.” DISCUSSION: Preretinal hemorrhage is an uncommon condition that can be mistaken for ophthalmologic emergencies such as retinal detachment. The images and videos shown here add to the body of evidence that POCUS is useful in diagnosing pre-retinal hemorrhage but must be differ-entiated from retinal detachment. These images also emphasize the need for further research and application of POCUS for the identification of preretinal hemorrhage.
