Analysis On Post-ocular Vascular Hemodynamics In Patients With Thyroid-associated Ophthalmopathy

Objective:TOstudy the changes of post-ocular vascular hemodynamics of patients with thyroid-associated ophthalmopathy (TAO) and the relation with CAS。Methods:TOchoose 31 patients (56 eyes) with TAO, and divided them intOtwOgroups according CAS:1-2scores is TAO1(32eyes),≥3scores is TAO2(24eyes)oThe retrobulbar hemodynamics of these patients were determined by color doppler flow imaging (CDFI), and 15 normal people (30 eyes) without TAOwere contrasted。The indexes included peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI), resistance index(RI) of ocular artery, the central retinal artery and posterior ciliary artery, alsOincluded maximum velocity (Vmax) and minimum velocity (Vmin) of the central retinal vein. Results:There were not statistically significance between TAO1 and normal people. There were statistically significance between TAO2 and normal people in PSV, EDV, PI, RI of the ocular artery, PSV, EDV, RI of the central retinal artery, PSV, EDV of the posterior ciliary artery, Vmax and Vmin of the central retinal vein (P<0.05)o There were statistically significance between TAO1 and TAO2 in PSV, EDV of the ocular artery, PSV, EDV, RI of the central retinal artery, PSV, EDV of the posterior ciliary artery, Vmax and Vmin of the central retinal vein。Conclusions:CDFI can detect the velocity of post-ocular vascular in patients with thyroid-associated ophthalmopathy and evaluate its activity, alsOcan offer important basis for clinical treatment。...
