Objective:

To assess the stroke risk following acute ischemic ocular events (IOEs) and their implications for systemic health, emphasizing the critical nature of these implications.

Key Findings:
  • 22.8% of patients experienced either an ischemic stroke (IS) (13.5%) or transient ischemic attack (TIA) (10.9%) within one year of an IOE.
  • 9.4% of patients had a cerebrovascular event on the same day as their ocular presentation.
  • Carotid artery stenosis significantly increased the likelihood of stroke or TIA by 60–75%.
  • Hypertension was present in over three-quarters of affected patients and is a key modifiable risk factor.
Interpretation:

IOEs should be viewed as critical warning signs of imminent cerebrovascular events, necessitating urgent evaluation and follow-up to prevent adverse outcomes.

Limitations:
  • Potential coding inaccuracies in electronic health records may affect the reliability of the data.
  • Incomplete capture of external care and behavioral risk factors such as alcohol and tobacco use could limit the understanding of risk profiles.
Conclusion:

IOEs are systemic warning signs requiring acute management and ongoing vigilance, highlighting the need for integrated care between ophthalmology and stroke services to improve patient outcomes.
