Purpose: To analyze the association between retinal vascular caliber and cardiovascular risk factors including smoking, blood pressure, diabetes and age.
Methods: This study included 60 Korean male participants 40-69 years of age. The retinal vessel caliber was measured using computer-assisted fundus photography. Four vessels coursing through the area of one half disc diameter from the optic disc margin were measured. Additionally, we analyzed the association between the retinal vessel caliber and risk factors including smoking, diabetes, hypertension and age.
Results: Smoking was not significantly associated with retinal vessel calibers. The diabetes group showed larger average retinal vessel calibers than normal group, but veins were significantly wider (p < 0.05). The average retinal vessel caliber was wider and inferior vein and artery were significantly larger in the hypertension group (p < 0.05). Although the retinal vessel caliber increased with age, significance was observed only in the superior artery (p < 0.05).
Conclusions: In our study, retinal vessel caliber was easily measured using a semi-automatic computer program. This method should prove useful in further studies examining the correlation among retinal vessel caliber variations in many localized ophthalmologic disorder.
