Results of interval courses using the Zeniсa optical trainer kits in the treatment of acquired myopia with a hereditary predisposition in younger school children

Purpose. To study the results of interval courses of using the «Zeniсa» optical trainer kits in school settings for the treatment of acquired myopia in younger schoolchildren with a hereditary predisposition to it. Material and methods. The study included 20 students (40 eyes) from primary school classes with mild myopia and a hereditary predisposition to it, with an average age of 10.1 ± 0.44 years. Ophthalmological examination included questionnaires, visual acuity measurements, skiascopy, ophthalmoscopy, subjective refraction determination, relative accommodation reserves, and binocular stability of visual perception to hypermetropic retinal defocus. Results. After 2 courses of opto-reflector exercises with an interval of 6 months between them using the «Zeniсa» optical trainer kits, visual acuity increased on average from 0.41 ± 0.25 to 0.44 ± 0.25 (p<0.001), and accommodation reserves increased on average from 2.85 ± 1.08 D to 3.80 ± 1.54 D (p<0.01). The total binocular stability of visual perception to hypermetropic retinal defocus increased by 44 % in the far vision mode from 310 % to 354 % and by 94 % in the near vision mode from 419 % to 513 %. Conclusion. As a result of the conducted 2 courses of opto-reflector exercises with a 6-month interval between them using the «Zeniсa» optical trainer kits, compensation of chronic visual fatigue was noted and an increase in adaptive capabilities of the visual system was observed. The use of «Zeniсa» optical trainer kits in school settings allows for timely therapeutic and preventive measures for myopia aiming at normalizing the refractogenesis process.
