Key result
Lack of collateral circulation was significantly associated with an increased risk of developing ocular ischemia syndrome in patients with carotid artery occlusion (OR 4.245).
Why the study?
The study was conducted to explore risk factors associated with ocular ischemia syndrome in patients with late stage carotid artery occlusion.
Observational (n=87)
No
In patients with carotid artery occlusion, female sex and the absence of collateral circulation are significant risk factors for developing ocular ischemia syndrome.
May support closer ocular monitoring in female CAO patients; leaves open confirmation in larger prospective cohorts.
Prupose This study aims to explore risk factorsassociated with ocular ischemia syndrome (OIS) in patients with late stage carotid artery occlusion (CAO). Methods Eighty-seven patients with CAO were enrolled and examined via patient history questionnaire, carotid duplex ultrasonography,transcranial doppler sonography (TCD) and eye examination (slit lamp, ophthalmoscopes). Results Twenty-two patients were diagnosed with OIS. Female patients are more likely to development OIS (OR=2.78). Patients without collateral circulation were associated with risk of OIS (OR=4.245, P<0.05). Conclusions One quarter of patients with CAO patients had OIS and sex and non-collateral circulation building were associated with OIS.

Huang et al. (2019) conducted an observational in Carotid artery occlusion (n=87). Lack of collateral circulation vs. Presence of collateral circulation was evaluated on Development of ocular ischemia syndrome (OIS) (OR 4.245, 95% CI 1.44-12.5, p=0.0067). Lack of collateral circulation was significantly associated with an increased risk of developing ocular ischemia syndrome in patients with carotid artery occlusion (OR 4.245).
