Тонзиллогенные изменения в собственно сосудистой оболочке и сетчатке глаза в эксперименте

Abstract

Purpose. Experimental study of tonsillogenic changes in the choroid and retina in an. Material and methods. Clinical and functional studies of the eyes of animals were carried out 3 months after modeling of chronic tonsillitis. Fundus images were photographed using RETCAM II (USA) wide-field digital pediatric retinal camera. Optical coherence tomography (OCT) was performed on 3D OCT-1000 MARK II optical coherence tomograph (Topcon, Japan). The functional state of the microhemocirculatory bed in the equatorial part of the eye was determined transscleral with laser Doppler flowmetry using LAKK-02 analyzer. Results. 3 months after the modeling of experimental chronic tonsillitis, dystrophic changes in the layer of nerve fibers, RPE dysfunction, and a reduced thickness of the own choroid persist. There is a deterioration in the functional state of the microcirculatory bed in the equatorial part of the eye. Conclusion. The use of optical coherence tomography, along with laser Doppler flowmetry, seems to be promising in assessing chorioretinal changes after modeling chronic tonsillitis. In the long term, after modeling of chronic tonsillitis, dystrophic changes in the layer of nerve fibers, hyperplasia of RPE cells, and a decrease in the thickness of its own choroid persist. There is a deterioration in the functional state of the microcirculatory bed in the equatorial part of the eye. Key words: chronic tonsillitis, laser Doppler flowmetry, retinal pigment epithelium, nerve fiber layer, choroid.
