Endophthalmitis diagnosis supported by bedside ultrasound.

Endophthalmitis is a bacterial or fungal infection in the deep spaces of the eye. The diagnosis of endophthalmitis has traditionally been made by vitreous humor culture and is commonly missed on initial presentation. In this case report, we emphasize the role of ocular point-of-care ultrasound (POCUS) in revealing endophthalmitis as a primary differential diagnosis for a patient presenting with unilateral eye pain and significant swelling that limited physical examination of the eye.
