Insights

Central retinal artery occlusion (CRAO) is a rare cause of blindness. Point-of-care ultrasound (POCUS) in the emergency department rapidly diagnosed CRAO in two patients with vision loss.

Area of Science:

  • Ophthalmology
  • Emergency Medicine
  • Medical Ultrasound

Background:

  • Central retinal artery occlusion (CRAO) is a critical diagnosis presenting as sudden, painless vision loss, often linked to thromboembolic events.
  • Prompt diagnosis is essential in the emergency department (ED) due to the time-sensitive nature of CRAO to prevent permanent vision impairment.

Observation:

  • Two patients presented to the ED with unilateral, painless vision loss and significant risk factors for thromboembolic and atherosclerotic disease.
  • Point-of-care ultrasound (POCUS) was performed at the bedside upon patient arrival.

Findings:

  • POCUS enabled rapid and accurate diagnosis of CRAO in both presented cases.
  • The ultrasound findings facilitated immediate clinical decision-making.

Implications:

  • This case series highlights the effectiveness of POCUS as a valuable tool for evaluating patients with acute, painless vision loss in the ED.
  • Integrating POCUS into the diagnostic workflow can expedite the identification of CRAO, potentially improving patient outcomes.
