Результаты применения опытного образца аппарата «Визотроник мини» для лечения приобретенной миопии в школьных условиях

Abstract

Material and method. 25 children (50 eyes) were observed, including 13 girls and 12 boys with mild myopia, age averagly 11.2 ± 1.1 years. Ophthalmological examination included questionnaire examination, visometry, ophthalmoscopy, skeascopy, determination of subjective refraction, reserve of negative accommodation (RNA) by E.S. Avetisov method and determination of binocular vision stability (BVR) to hyperopic retinal defocus (HRD). The course of treatment, which consisted of 10 sessions, was conducted in the medical and pedagogical center of the school using the portable device “Visotronic Mini”. Results. As a result of using “Visotronic Mini” apparatus, visual acuity improved from 0.61 ± 0.25 to 0.72 ± 0.26 (P < 0.001) on average by 0.11. Subjective refraction decreased on average of (-) 0.34 dptr from (-) 0.96 dptr to (-) 0.62 dptr (P < 0,01). RNA increased on average 2.28 dptr from 5.36 ± 2.28 dptr to 7.98 ± 2.96 dptr (P < 0.01). The total visual resolution (VR), in far vision mode increased from 175 % to 311 %, and in near vision mode increased from 265 % to 413 %. Conclusion. As a result of using “Visotronic Mini” apparatus in school conditions during treatment of schoolchildren with mild myopia the work capacity of the accommodation-vergence apparatus increases and the binocular interaction improves, an ergonomic stereotype of visual work is formed, thereby creating conditions for formation of a high steady level of adaptive resource of the visual system. The apparatus “Visotronic Mini” is effective and convenient for conducting treatment sessions in organized groups, in particular in school conditions. Key words: myopia, adaptive resource, “Visotronic Mini” device.
