To measure and consider changes of blood flow velocity by color Doppler imaging in the ophthalmic artery (OA), short posterior ciliary arteries (PCA) in myopic and glaucoma patients and to compare the results with those in healthy emmetropic volunteers.

Thirty patients with open-angle glaucoma, ten patients with slight myopia ( -8.0 diopters), and thirty healthy emmetropic volunteers were enrolled in the study. We used Doppler sonography to determine hemodynamic parameters of OA, and PCA. We measured the peak systolic velocity (PSV cm/s) and resistance index (RI). Statistical significance was set at p<0.05.

Colour Doppler imaging in high myopic and glaucoma patients showed decreased PSV and increased RI in the AO and in the PCA compared with healthy emmetropic volunteers . There were no statistically significant differences of hemodynamic parameters in slight and mild myopia compared with healthy emmetropic volunteers. Moreover the hemodynamic variations measured in high myopic and glaucoma patients were significantly correspondent.

The study showed a significant variations of bulbar flow and a statistical correspondence of the hemodynamic variations in high myopic and glaucoma patients. This indicates a possible coexistence of the two ocular pathologies.

Colour Doppler imaging is a non-invasive technique that allows further estimation of the ocular circulatory status and may have predictive power in identifying myopic patients at greatest risk to develop glaucomatous optic neuropathy.
