| Summary: | Introduction. Vitreous opacities are quite common, occurring in 76% of cases and significantly reducing quality of life in 33% of them. YAG-laser vitreolysis is considered as an alternative treatment option for patients with floating vitreous opacities. Purpose. To develop an optimized YAG-laser vitreolysis technology based on the assessment of the acoustic density of the vitreous opacities. Material and methods. The results of YAG-laser vitreolysis of vitreous opacities in 318 patients (318 eyes) were analyzed. A photo-optical method has been developed for visualizing opacities of the vitreous body, registering the area of opacities and the dimming intensity index. A method has been developed for the personalized selection of laser energy taking into account the acoustic density of the vitreous opacities. Results. After performing multi-stage laser treatment, a significant decrease in the area of opacities and the dimming intensity index, an increase in the threshold of retinal photosensitivity according to microperimetry data and a decrease in the acoustic density of opacities were noted. Conclusions. Application of optimized YAG-laser vitreolysis technology for vitreous opacities allows to achieve the best values of clinical and functional parameters (p<0.05). |
