The Use of Point-of-Care Ultrasound for a Rapid Diagnosis of Endophthalmitis: A Case Report.

Acute and subacute vision loss often requires specialized evaluation in emergency departments. Endophthalmitis, a serious eye infection, can be challenging to diagnose early but is critical to identify due to its potential severity. This case report illustrates the use of ocular point-of-care ultrasound (POCUS) in diagnosing endophthalmitis in a 72-year-old male initially thought to have orbital cellulitis. Despite swollen and painful eyes hindering direct examination, the ocular POCUS examination revealed intraocular hyperechoic debris, indicating an intraocular infection suggestive of endophthalmitis. This timely diagnosis facilitated quick and appropriate treatment, highlighting the role of ocular POCUS in the emergency department for swift and accurate assessment.
