Editor,—Behçet’s disease (BD) is an immune system related obstructive vasculitis characterised by recurrent inflammation that affects multiple systems. Posterior uveitis and retinal vasculitis are the common features of ocular involvement.1-3 Colour Doppler imaging (CDI) is a non-invasive ultrasonographic method which permits simultaneous grey scale imaging of structure and colour coded imaging of blood velocity. CDI has successfully demonstrated changes in orbital haemodynamics associated with a variety of pathological conditions.4-7In the present study the haemodynamic changes in ophthalmic (OA), central retinal (CRA), and posterior ciliary arteries (PCA) of the patients with BD were investigated by using CDI.
The study group consisted of 26 patients with BD (five females, 21 males), aged between 22 and 58 (mean 32.19 (SD 8.27)). Diagnosis was made according to the criteria recommended by International Study Group for Behçet’s disease.8 Control group consisted of 20 males, six females, aged between 21 and 58 (31.49 (8.60)), who had no ocular or systemic pathology other than presbyopia.
After performing full ophthalmological evaluation, transocular CDI was performed in all the patients and controls with a colour Doppler sonographic unit (General Electric Sonochrome …
