Color Doppler imaging in evaluation of optic nerve blood supply in normal and glaucomatous subjects.

The authors evaluate by means of Color Doppler Imaging (CDI) the blood flow in ophthalmic artery, posterior ciliary arteries and central retinal artery in a group of glaucomatous patients. The data obtained in this study show a statistically significant reduction of the mean systolic peak flow velocity in ophthalmic artery in glaucomas in comparison with controls. In Glaucomatous patients with uncontrolled IOP there was a reduction of end-diastolic flow velocities and a rise of resistivity index in ciliary arteries and central retinal artery.
