Abstract

Color Doppler imaging (CDI) is a noninvasive technique, combining 2-dimensional brightness-modulated (B-mode) ultrasound evaluation of eye and orbital structures, with simultaneous color-coded Doppler imaging of orbital blood flow. It has been used to characterize various ophthalmic disorders in adults. Currently there is no data describing orbital blood flow parameters in either normal children or in those with ophthalmic disease, such as the retinopathy of prematurity (ROP). We evaluated blood flow in the central retinal artery of preterm infants undergoing examination for ROP. We also investigated whether useful readings could be obtained on a consistent basis, and the reproducibility of differences in central retinal artery blood flow between subjects with and without ROP (including the influence of "plus" disease). We obtained hemodynamic readings in 43 of 46 eyes of preterm infants. 13 eyes had no signs of ROP; 18 had ROP (at least stage 1) without "plus" disease, and 12 had ROP with "plus" disease. There were no statistically significant differences in systolic blood flow velocity within the 3 groups. However the average velocity was slower in the "plus" disease group, correlating with the clinical finding of dilated and tortuous blood vessels which characterize the posterior retina of ROP eyes with "plus" disease.
