title: Correlation between visual field and color Doppler parameters in chronic open angle glaucoma.
abstract: The authors evaluated, by means of colour Doppler imaging, the blood flow in ophthalmic artery and posterior ciliary arteries in subjects with chronic open angle glaucoma. On the basis of the visual field indices (MD, SF, CPSD) the patients' eyes were divided in two groups: group A with better indices and group B with great damage. At the posterior ciliary arteries they found these values: PSV 10.264 +/- 2.363 cm/s (group A) vs. 7.882 +/- 1.251 cm/s (group B) (p < 0.008); RI 0.615 +/- 0.065 (group A) vs. 0.695 +/- 0.064 (group B) (p < 0.009). These data highlight a correlation between the visual field damage and the reduced supply of optic nerve head.
