Thirty-six individuals (72 eyes) were examined.</p> <p><bold>Results.</bold> The blood flow parameters were studied in the ophthalmic artery (OA), central retinal artery (CRA), short posterior ciliary arteries (PCA) on the temporal side, angular artery of the eye (AngA), and central retinal vein (CRV). The following parameters were obtained: peak systolic blood velocity (PSV), end-diastolic blood velocity (EDV), resistance index (RI), pulsatility index (PI), average blood flow velocity over one cycle (TAMAX), and systolic acceleration time (acct). Blood flow in the angular artery is characterized for the first time. The average values ​​(M ± m) of blood flow characteristics for the studied vessels were: for OA PSV – 23.7 ± 0.8 cm/s, EDV – 6.3 ± 0.3 cm/s, RI – 0.73 ± 0.01, TAMAX – 11.1 ± 0.5 cm/s, PI – 1.63 ± 0.06, Acct – 0.055 ± 0.001; for CRA PSV – 10.2 ± 0.4 cm/s, EDV – 2.5 ± 0.1 cm/s, RI – 0.75 ± 0.01, TAMAX – 1.64 ± 0.2 cm/s, PI – 1.64 ± 0.06, Acct – 0.055 ± 0.001; for PCA PSV – 13.3 ± 0.7 cm/s, EDV – 4.0 ± 0.3 cm/s, RI – 0.69 ± 0.01, TAMAX – 7.3 ± 0.4 cm/s, PI – 1.30 ± 0.04, Acct – 0.057 ± 0.001; for AngA PSV – 17.2 ± 0.7 cm/s, EDV – 4.6 ± 0.2 cm/s, RI – 0.72 ± 0.02, TAMAX – 7.8 ± 0.03 cm/s, PI – 1.71 ± 0.07, Acct – 0.056 ± 0.001; for CRV PSV – 4.5 ± 0.2 cm/s, EDV ¬ 2.5 ± 0.1 cm/s, RI – 0.45 ± 0.01.</p> <p><bold>Conclusion.</bold> Reference blood flow data obtained by ultrasound dopplerography of ocular vessels in apparently healthy individuals are presented.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель –</bold> установить референтные характеристики ретробульбарного кровотока по данным ультразвуковой допплерографии для условно здоровых людей</p> <p><bold>Материал и методы.</bold> Проведена ультразвуковая допплерография ретробульбарных сосудов группе добровольцев.
