The aim of this prospective study was to assess the ocular hemodynamic changes in patients with Behçet's disease who had involvement of the posterior segment by color Doppler ultrasonography.


The present study was carried out in 32 eyes of 24 patients with ocular Behçet's disease and 42 eyes of 21 persons as a healthy age-matched control group. In order to detect the hemodynamic changes in ocular Behçet's disease, peak systolic and end-diastolic velocities (PSV, EDV; cm/sec), resistive and pulsatile indices (RI, PI), and PSV/EDV ratio of central retinal artery (CRA), short posterior ciliary artery (PCA) and ophthalmic artery (OA) were determined.


The mean PSV and EDV (8.1±2.6 and 2.7±0.1 cm/sec, respectively) in the CRA were significantly lower in patients with Behçet's disease than in healthy controls (11.5±2.2 and 3.5±1.0 cm/sec, respectively, p<0.001). For the PCA, these values (12.7±4.2 and 4.3±1.1 cm/sec, respectively) were significantly lower in the patient group than in the control the group (18.2±4.2 and 6.1±2.5 cm/sec, respectively, p<0.001). In the patient group, a statistically significant decrease compared to the control group was detected in the mean PSV of the OA (31.8±8.2 and 35.8±0.6 cm/sec, respectively, p<0.02). However, no significant difference in the other parameters of these vessels was observed between groups.


These results demonstrate the presence of some circulatory changes in the flow velocities of the CRA, PCA and OA in patients with Behçet's disease when compared with control subjects.
