Hypertension and cardiovascular disorders are common in patients with retinal artery occlusions (RAO). This study highlights the systemic links to RAO, including diabetes and cerebral infarction.

Area of Science:

  • Ophthalmology
  • Vascular Medicine
  • Neurology

Context:

  • Retinal artery occlusions (RAO), including central (CRAO), branch (BRAO), and cilioretinal (CIAO) types, represent significant causes of vision loss.
  • Understanding the underlying systemic disorders associated with RAO is crucial for effective patient management and risk stratification.

Purpose:

  • To investigate the prevalence of systemic disorders in patients diagnosed with central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO), and cilioretinal artery occlusion (CIAO).
  • To identify common comorbidities and risk factors contributing to the development of RAO.

Summary:

  • A review of 36 patients (37 eyes) with CRAO, BRAO, and CIAO revealed hypertension as the most frequent comorbidity (58%).
  • Cardiovascular disorders (e.g., ischemic heart disease, atrial fibrillation) were present in 50% of patients, while diabetes mellitus (17%) and hyperlipemia (8%) were also noted.

  • Cerebral infarction occurred in 25% of patients. The incidence of CRAO was 1 per 1,000 outpatients, with a peak incidence in the seventh decade, and a higher prevalence in men and in the right eye.

    • Impact:

    • This study underscores the critical importance of screening for systemic vascular and cardiovascular diseases in patients presenting with retinal artery occlusions.
    • Identifying these underlying conditions can guide preventative strategies and improve long-term patient outcomes by managing modifiable risk factors.
