[Electroencephalography in schoolchildren aged 10-12 years with myopia]

Electroencephalography was performed in schoolchildren aged 10-12 years with emmetropia (n=38) and myopia of different degree (n=165), the goal was to study alpha-rhythm frequency, configuration and maximum amplitude. 16-channel device "Neuron-Spectr-3" (Russia) was used. Student criterion was counted with 95% confidence interval. Significant decrease of alpha-rhythm was found in children aged 10-12 years with myopia compared to control group (p < 0.05). Interhemisphere asymmetry of alpha-rhythm frequency and slowing of alpha-rhythm were revealed in schoolchildren with myopia only. Slowing and decrease of amplitude of alpha-rhythm are registered on the very early stages of myopization process before development of axial myopia.
