Colour Doppler imaging (CDI) of orbital vessels is non‐ invasive but may be fallacious, while computed tomography (CT) angiography displays a visual outline of orbital vessels. We compared clinical findings of the two methods in 33 patients with a wide variety of clinical conditions. It was not possible to visualize the central retinal arteries with CT angiography, but it was possible to show the intracranial carotid, which CDI could not. Changes in the ophthalmic arteries on CDI usually showed changes in calibre on CT angiography. Patients with unexplained or gross visual loss often showed marked abnormalities on CT scanning, not entirely consistent with the clinical picture. Several patients showed marked ectasia of the intracranial carotid along with variable clinical findings. Findings on CT angiography complement and augment those on CDI, and are likely to be more clinically valuable in the future.
