Аннотация
Лазерная спекл-флоуграфия — неинвазивный метод количественной оценки перфузии сетчатки, сосудистой оболочки и диска зрительного нерва. В основе метода лежит явление спекл-флоуметрии, представляющей формирование спекл-структур при освещении сосудов диодным лазером 830 нм. Программное обеспечение LSFG Analyzer анализирует спекл-паттерны, что позволяет получить количественную информацию о внутриглазном кровотоке. За несколько часов до исследования пациент должен воздержаться от приёма пищи, употребления стимулирующих напитков, находиться в состоянии физического и эмоционального покоя. Результатом проведённого анализа являются многочисленные характеристики пульсовой волны: Blowout Score, Blowout Time Skew, Acceleration Time Index, Rising Rate, Falling Rate, Flow Acceleration Index, Resistivity Index, Relative Flow Volume. Лазерная спекл-флоуграфия открывает новые возможности в изучении патогенеза, диагностики и в оценке эффективности лечения возрастной макулярной дегенерации, центральной серозной хориоретинопатии, окклюзий ретинальных вен, диабетической ретинопатии, ишемической нейрооптикопатии, неврита зрительного нерва и других заболеваний сетчатки, сосудистой оболочки и диска зрительного нерва. Помимо этого, лазерная спекл-флоуграфия используется для оценки влияния физических нагрузок, беременности, системных заболеваний, лекарственных средств на состояние внутриглазной гемодинамики.
