摘要
The authors evaluated, by means of color Doppler imaging, the blood flow of the ophthalmic artery, ciliary arteries and central retinal artery in normal and glaucomatous subjects. In normals they found that flow velocities of all considered vessels progressively decline while resistivity indices increase with advancing age. In glaucomatous subjects there was a statistically significant reduction of the mean systolic peak flow velocity of the ophthalmic artery in comparison with normals. Glaucomatous eyes with uncontrolled IOP and with visual-field worsening showed a statistically significant decrease in the end-diastolic flow velocities and an increase in the resistivity index values in ciliary arteries.
