Point-of-care ocular ultrasound to detect optic disc swelling.

Objectives: Emergency physicians (EPs) frequently evaluate patients at risk for diseases that cause optic disc swelling, and they may encounter conditions that make traditional fundoscopy difficult or impossible. The objective was to assess whether EP-performed point-of-care (POC) ultrasound (US) could accurately assess swelling of the optic disc.

Methods: This was a blinded, prospective study using a convenience sample of patients presenting to a neuroophthalmology clinic who were thought to be at risk for conditions associated with optic disc edema.
