Clinical Trial
Doppler ultrasound of blood flow velocities in ophthalmic and central retinal arteries during the early neonatal period.
To obtain standard values of blood flow velocity in the ophthalmic artery and central retinal artery in the neonatal period and to compare blood flow velocity of orbital vessels with that of the anterior cerebral artery and middle cerebral artery. ⋯ We report blood flow data of the ophthalmic artery and central retinal artery in healthy neonates and suggest that a delay of arterial blood flow changes occurs for the ophthalmic artery and central retinal artery with respect to the anterior cerebral artery and middle cerebral artery in the early prenatal period.
