Abstract
Purpose: to study the accommodative function in contemporary schoolchildren using the method of computer accommodography.Material and methods. 74 children aged 10–16 (54 with different degrees of myopia and the control group of 20 emmetropic children) were tested on a Righton Speedy-K ver. MF-1 computer accommodograph to determine the accommodative response to accommodation stimulus (by calculating the coefficient of the accommodative response, CAR) and the contraction of ciliary muscle fibers (by determining the microfluctuation coefficient, CMF).Results. In groups of patients with emmetropia and weak myopia, CAR and CMF were found to exceed the normal values. The low myopia group demonstrated especially pronounced changes. In moderate and high myopia, the CAO is significantly lower than in low myopia or emmetropia, while the CMF also exceeds normal values.Conclusion. The spastic component of accommodation is of great importance in the pathogenesis of progressive myopia of present-day schoolchildren, which is expressed in the strengthening of the accommodation response with regard to the accommodation stimulus and pathological frequency increase of accommodative microfluctuations.
