The peak systolic velocity and the resistance index of the ophthalmic artery, the ciliary and choroidal arteries were examined by using the color doppler imaging technique in 70 subjects. The authors considered 20 patients with myopia between 5 and 10 D (group A), 20 patients with myopia < 11 D (group B), ten patients with low tension glaucoma ( < 20 mmHg) and 20 healthy subjects (control group). In groups A and B, the velocimetric values of the ophthalmic artery were found statistically significant only in myopia > 11 D compared with control group; while the ata of the posterior ciliary and choroidal arteries were always found statistically significant. The velocimetric values in patients with low tension glaucoma were found similar to those found in patients with myopia > 11 D in each districts. On the base of this similarity, the authors suggest that both low tension glaucoma and in myopia > 11 D can cause a vascular alteration damaging the optic nerve. LA: Italian
