Doppler ultrasonography findings in ocular Behçet's disease

Changes of Central Retinal Artery Blood Flow and Endothelial Function in Patients with Coronary Artery Disease

“…15 The current study demonstrates that PSV, EDV, and TVI of CRA blood flow were significantly reduced, and RI and PI were significantly increased in CAD patients compared with normal controls. In support of our data, a decrease of blood flow velocity and increase of vascular resistance are often observed in the aged, and in many eye diseases, such as glaucoma, 16,17 diabetic retinopathy, 18−20 macular degeneration, 21 Behçet disease, 22,23 and retinitis pigmentosa, 24 the reduction of CRA blood flow tends to become larger in proportion to the progress of the disease. Moreover, Taylor and co-workers indicate that resistance is inversely related to flow velocity.…”

Doppler sonography of ocular and carotid arteries in Behçet patients

“…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.…”

“…Similarly, studies including Behçet patients without ocular involvement and controls showed no statistically significant difference in Doppler variables of retro-orbital arteries. 5,7,12,13,15 In conclusion, we found significantly lower blood flow velocities in some retro-orbital vessels (CRA, CRV, NPCA) and ICA of patients with ocular Behçet disease compared with healthy volunteers. Moreover, NPCA hemodynamics may help differentiate active and inactive uveitis and contribute to the clinical follow-up of Behçet patients.…”

Color Doppler Imaging of the Orbital Vessels in Ankylosing Spondylitis

“…3 Some major hemodynamic changes are seen in orbital and ocular vessels in Behçet's Disease (BD) (with or without ocular involvement), which also includes uveitis. [4][5][6][7][8] Likewise, ocular blood flow velocities were significantly lowered in patients with different etiological uveitis compared to controls in a study report. 9 Finally, the ocular blood stream was also shown to be impaired in a study performed to investigate whether primary atherosclerosis may be one of the underlying causes of ocular involvement in rheumatoid arthritis (RA).…”

“…17,21 Studies investigating orbital blood flow using DU in chronic inflammatory rheumatic diseases with orbital involvement have generally been completed with Behçet's disease (BD). [4][5][6][7][8][22][23][24] Blood flow velocities of orbita were detected to decrease in BD with or without ocular involvement, as compared to controls. While some authors state that this reduction is more prominent in patients with orbital involvement, 6,22 others state the opposite.…”
