Orbital - Retinal Edema (2/2 - Clip)
Caption
17 y/o female with sudden onset bilateral blurry vision after prolonged indoor cat exposure. Fundoscopy showed retinal pigment epithelium loss consistent with bilateral neuroretinitis from cat scratch disease (Bartonella henselae). The hyperechoic retina, normally flush with the posterior aspect of the globe, is seen separated by a hypoechoic band of edema. Retinal edema from cat scratch disease is rare (Gen Opth 19th ed. 2017:378-422), but can be diagnosed by POCUS. Contributed by: John Hipskind, MD, Ultrasound Director, Kaweah Health EM Residency
