Color Doppler Imaging of Ocular Hemodynamic Changes in BehÇet’s Disease

摘要

Subjects were divided into three groups: those with ocular involvement in BehÇet’s disease (group I), those without ocular involvement in BehÇet’s disease (group II), and a control group (group III). Twenty-seven eyes in group I and 28 eyes each in groups II and III were investigated. The blood flow in the central retinal artery (CRA), ophthalmic artery (OA), nasal posterior ciliary artery (NPCA), and the temporal posterior ciliary artery (TPCA) was measured using color Doppler ultrasonography (CDU) to determine the peak systolic velocity (PSV), end diastolic velocity (EDV), and resistivity index (RI). The mean blood flow velocity of the central retinal vein (CRV) was also measured. These results were then compared among the three groups of subjects.
