Abstract
OBJECTIVE: To study the clinical values of measurement of blood flow velocity in central retinal artery in thyroid-associated ophthalmopathy (TAO). METHODS:Thirty normal subjects without any thyroid disorders or any eye abnormalities were assigned into the control group, and 30 TAO patients were assigned into the TAO group. Color Doppler ultrasonography was done to measure the blood flow velocity in central retinal artery. Measurement results were compared between these two groups. RESULTS: The peak systolic velocity and end diastolic velocity of blood flow were significantly lower in TAO group (P < 0.001), while the resistance index significantly increased (P < 0.001). CONCLUSION: Measurement of blood flow velocity in central retinal artery with Color Doppler ultrasonography is an easy and useful way to appraise the hemodynamics of the central retinal artery in TAO patients.
