Маломощный зондирующий лазер с импульсами 7-10 нс генерирует в пигментном эпителии сетчатки акустические волны, регистрирующиеся акустическим приемником, расположенном на трехзеркальной линзе, помещаемой на роговицу глаза. Амплитуда акустической волны позволяет судить о значении в этой точке коэффициента оптического поглощения - величины, определяющей температуру нагревания области после воздействия терапевтического лазера. Для расчета температурного поля используется трехмерная модель теплопроводности, которая позволяет определить распределение температуры в любой точке при нагреве коагулятором, а также после его выключения. Эксперимент был проведен на 2 глазах 1 кролика породы шиншилла серый in vivo, планировалось получить коагуляты 2 степени по классификации L' Esperance, ориентируясь на температурное распределение. Всего из 20 поставленных в разных точках коагулятов 17 были признаны коагулятами 2 степени по классификации L' Esperance.</p></abstract><trans-abstract xml:lang="en"><p>The technology of control of laser action on the retina, based on the use of optoacoustic sounding, is discussed. A 丨ow-power probing laser with pulses of 7-10 ns generates acoustic waves in the retinal pigment epithelium, which are detected by an acoustic receiver located on a three-mirror lens placed on the cornea of the eye. The amplitude of the acoustic wave makes it possible to judge the value of the optical absorption coefficient at this point, a value determining the heating temperature of the region after the action of the therapeutic laser. To calculate the temperature field, a three-dimensional model of thermal conductivity is used, which allows determining the temperature distribution at any point during heating by the coagulator, and also after it is turned off. The experiment was carried out on 2 eyes of 1 rabbit of the chinchilla gray breed in vivo, it was planned to obtain 2 degrees of L 'Esperance coagulation according to the temperature distribution. In total, 17 out of 20 delivered at different points of coagulation were recognized as coagulants of the 2nd degree according to the classification of L 'Esperance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коэффициент оптического поглощения</kwd><kwd>распределение температурного поля</kwd><kwd>лазеркоагуляция</kwd><kwd>оптоакустика</kwd><kwd>optical absorption coefficient</kwd><kwd>temperature field distribution</kwd><kwd>laser coagulation</kwd><kwd>optoacoustics</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">Framme C., Roider J. et al.
