| Summary: |
Purpose: of the
study was to evaluate blood flow in the arteries of the
eye in preterm neonates.
Material and methods: Color Doppler imaging (CDI)
of ophthalmic artery, central retinal artery and
posterior ciliary arteries was performed in 36 preterm
infants and 19 full-term infants. Maximal systolic
velocity, end-diastolic velocity, resistance index- RI
and pulsatility index- PI were assessed for the studied
vessels.
Results: There were no significant differences in
ophthalmic artery blood flow between preterm and normal
newborns. End-diastolic velocity in central retinal
artery and posterior ciliary arteries in preterm infants
was significantly lower and resistent index and
pulsatility index was higher. The Doppler color
ultrasonography is a non-invasive technique which can be
useful for the estimation of the hemodynamic parameters
in the arteries of the eye in the prematures.
Conclusions: The recorded changes in the
ultrasound measurements of the blood flow in the eye
arteries in premature children comparing to the normal
newborns, can be the evidence for the immaturity of the
vessel system in the preterm born neonates. |
