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

Int Ophthalmol. 1992 Sep;16(4-5):273-6. doi: 10.1007/BF00917974.


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.
