Relevance. The authors performed ultrasound Dopplerography to determine the blood flow velocity in the central retinal vein at different degrees of intracranial hypertension development. Purpose of the study. Thus, at the initial stage of hypertensive syndrome development, the blood flow velocity in the central retinal vein of the systolic blood flow velocity decreases by 1.0 cm. sec, and the diastolic blood flow velocity by 0.7 cm. sec. Materials and methods. At the developed stage of hypertension, with the appearance of a pronounced degree of congestion of the optic nerve papilla, the systolic blood flow velocity slows down by 2.1 cm. sec and the diastolic blood flow velocity by 1.6 cm. sec. Results and conclusion. At the stage of regression of the congestion of the optic nerve papilla, some acceleration of the systolic blood flow velocity in the central retinal vein by 1.2 cm. sec and the diastolic velocity by 1.0 cm. sec is restored. Determining the blood flow velocity in the central retinal vein is a timely diagnosis.
