Haemodynamic changes in ocular Behcet's disease

Doppler sonography of ocular and carotid arteries in Behçet patients

“…4,5,8,[12][13][14][15][16] CRA PSV, EDV, and Vmean were significantly lower in patients with active or inactive uveitis than in patients without uveitis or in controls, as reported by others. 7,12,13 However, we found no significant difference between active and inactive PSV and/or EDV of both TPCA and NPCA's are lower BD patients with uveitis than without uveitis.…”

“…6,7,13,17 In contrast to Soylu et al's and Yanık et al's study, we found NPCA blood flow differences between patients with active and inactive uveitis. 14,15 In our study, PSV and EDV were significantly lower in patients with active uveitis than in the other groups in NPCA, but not in TPCA. This might be explained by the fact that we included patients in an early phase of the disease.…”

Ocular Blood Flow Changes in Behçet Disease Patients with/without Thrombotic Disease

“…6 There are several studies conducted to examine the orbital haemodynamic changes in BD. [19][20][21][22][23][24][25][26][27] In these studies, reduction in orbital blood flow and increase in RI were reported in BD patients and the most common finding was the reduction in the CRA blood flow compared with the normal subjects. 20,23,28 Reduction in OA and TPCA blood flows have also been found in BD patients.…”

“…21,22 In addition, increased TPCA PI values have been reported in ocular BD patients compared with the control group. 23,26 These findings (EDV and PSV reduction and PI increase in TPCA) indicate that choroidal circulation is also involved by vasculitis, which is difficult to detect clinically. Previous studies showed no differences in the TPCA flow parameters between non-ocular BD patients and the normal control subjects.…”

“…Seckin et al and Soylu et al did not report any differences in all three vessels of the eyes for active and inactive uveitis patients. 25,26 BD, which is systemic vasculitis, may involve both arteries and veins. However in more than 90% of cases it involves veins.…”
