Abstract
The purpose of this study is to study the state of accommodative function in contemporary schoolchildren using the method of computer accommodation.
We studied 50 children (10-16 years old): 40 with different degrees of myopia and 10 children (control group) with emmetropia. The accommodation was studied with the computer accomodate Righton Speedy-K ver. MF-1. Defined power of accommodative response to accommodative stimulus imposed by calculating a ratio the coefficient of accommodative response (CAR) and the nature of the contraction of the fibers of the ciliary muscle by determining microfluctuations coefficient (CMF).
It was found that in groups of patients with emmetropia and weak myopia, the coefficient of accommodation response and the microfluctuation coefficient exceed the average normal values. Especially pronounced changes in the group of children with mild myopia. In groups of children with moderate and high myopia, the CAR is significantly lower than in mild myopia and emmetropia, while the CMF also exceeds normal values.
