HEMODYNAMIC INDICES IN THE RETINAL VESSELS IN RETINOPATHY OF PREMATURITY IN ACTIVE PHASE OF THE DISEASE
An analysis of the quantitative parameters of hemodynamic indices in the vessels supplying the retina (central retinal artery, posterior short ciliary arteries) in children with early features of retinopathy of prematurity (RP) was conducted. The main group included 38 infants (68 eyes) with RP of I-III stages in active phase, and as a control served the indices of linear blood flow velocity in central retinal artery and posterior short ciliary artery of 39 eyes of 21 premature infants without RP features and that of the group of 18 healthy mature infants (36 eyes). Linear velocity of diastolic blood flow (Vdiast) and index of vascular resistance (RI) proved to be the most hemodynamically significant indices. It was ascertained that in clinical features increase accompanied by the pronounced changes on fundus occurred an abrupt drop of the diastolic blood flow linear velocity (Vdiast) and the significant RI increase in comparison with the control group. Quantitative indices depend on the RP stage.
