Лазерная спекл-флоуграфия (LSFG) является новым методом двухмерной оценки глазного кровотока, и оценка его информативности представляет значительный интерес.</p><p>Цель работы — изучить возможности LSFG для определения глазного кровотока и оценить зависимость показателей LSFG от возраста.</p><sec><title>Материал и методы</title><p>Материал и методы. Обследованы 60 здоровых добровольцев, разделенных на группы по 20 человек в зависимости от возраста: 20–40, 41–60 лет и ³ 61 года. Все обследуемые имели высокую остроту зрения и нормальные параметры артериального давления. Исследование проводили на приборе LSFG-RetFlow (Nidek), определяли форму пульсовой волны, ее качественные и количественные характеристики, а также MBR — Mean Blur Rate («средний показатель размытости изображения») — основной параметр, определяемый при LSFG.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено значимое снижение объемных показателей кровотока с возрастом, различия большинства исследуемых показателей между всеми тремя группами достоверны (р £ 0,05). Наиболее высокие значения MBR отмечены в группе 20–40 лет. В макулярной области показатели MBR более значимо снижались в группе старше 60 лет, тогда как для диска зрительного нерва (ДЗН) снижение отмечалось уже после 40 лет. В среднем снижение составило 25–34 % в области ДЗН и 33–38 % в макулярной области. Изменения параметров формы пульсовой волны имели сходную тенденцию.</p></sec><sec><title>Заключение</title><p>Заключение. LSFG представляет собой надежный метод количественной оценки глазного кровотока. Наши данные подтверждают, что выявляемые методом LSFG показатели MBR и их производные могут быть полезными биомаркерами глазной перфузии. Выявленные возрастные изменения следует учитывать при анализе офтальмопатологии.</p></sec></abstract><trans-abstract xml:lang="en"><p>Disorders of ocular perfusion are associated with huge amout of diseases, including such socially significant as diabetic retinopathy and glaucoma. To date, there is no gold standard for measuring ocular perfusion. An innovative method for two-dimensional assessment of eye blood flow — laser speckle flowgraphy (LSFG) — has been developed recent years and implemented in ophthalmological practice.</p><sec><title>Purpose</title><p>Purpose: to evaluate the possibilities of LSFG for determining ocular blood flow and to find out the age dependence of the obtained indicators of ocular blood flow.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study includes 60 healthy volunteers. The examined persons were divided into 3 groups of 20 people depending on their age — 20–40 years old, 41–60 years old, and over 61 years old. All examined persons had high visual acuity and normal blood pressure. The study was carried out on an LSFG-RetFlow device (Nidek). The shape of the pulse wave, its qualitative and quantitative characteristics including the main parameter of LSFG - MBR (Mean Blur Rate) were determined.</p></sec><sec><title>Results</title><p>Results. A significant decrease with age of most studied parameters of blood flow volume was revealed, the changes were significant (p £ 0.05). The highest MBR parameters were noted in the group of 20–40 years old. In the macular area, MBR values decreased more significantly in the group after 60 years age, while for the optic nerve head (ONH), a decrease has been already noted after 40 years age. In average, the decrease was 25–34 % for the ONH area and 33–38 % for the macular area. Changes of the other parameters of the pulse waveform had a similar trend.</p></sec><sec><title>Conclusion</title><p>Conclusion. LSFG is a reliable method for quantifying ocular blood flow. Our data support that LSFG-derived MBR and pulse wave measurements may be useful biomarkers for ocular perfusion changes. The identified age-related blood flow changes should be taken into account during the analysis of patients data.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерная спекл-флоуграфия</kwd><kwd>глазной кровоток</kwd><kwd>возрастные изменения</kwd><kwd>гемоперфузия глаза</kwd><kwd>MBR</kwd><kwd>показатели пульсовой волны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser speckle flowgraphy</kwd><kwd>ocular blood flow</kwd><kwd>age-related changes in blood flow</kwd><kwd>MBR</kwd><kwd>pulse wave parameters</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Luft N, Wozniak PA, Aschinger GC, et al.
