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.
Abstract:
Central retinal artery occlusion (CRAO) is a rare, but serious, diagnosis that can lead to blindness, most often due to thromboembolic disease. In the emergency department (ED), CRAO can present as acute, painless loss of vision. Physicians need quick ways to rule in this diagnosis due to the time-sensitive nature of the event. We describe two patients in this cases series who present to the same ED with unilateral painless vision loss and histories that include notable risk factors such as thromboembolic and atherosclerotic disease. Upon arrival, point-of-care ultrasound (POCUS) done at the bedside allowed for quick determination of CRAO. The importance of this case series is to emphasize the efficacy of POCUS in evaluating patients with painless vision loss in the ED setting.
