Эффективность применения световой нервно-зрительной стимуляции у детей младенческого возраста с задержкой зрительного созревания

Abstract

Purpose. To study the effectiveness of neuro-visual light stimulation in infants with delayed visual maturation (DVM). Material and methods. The study involved 22 infants with DVM at the age of 2–3 months. In all children, the movements of the eyeballs were insufficiently coordinated; there were also no visual reflexes of tracking and stable fixation. All patients were divided into two groups – the main (12 people) and comparison (10 people). Children of both groups received neurotropic therapy. Additionally, patients of the main group were prescribed light therapy of fontanelles with the Bioptron device daily for 30 seconds in one session (15 seconds for each fontanel). The duration of the course was 15 days with a frequency of course treatment every 1–1.5 months until the desired therapeutic effect is obtained. Efficiency criteria: the rate of development of visual functions and behavioral reactions corresponding to the variant of the age norm. Results. After the first course of using the Bioptron device, 8 out of 12 children of the main group developed a tracking reaction, gaze fixation, and consistency in the movements of the eyeballs. In three children – only after the second course of light therapy, and in one child – after the third course of treatment. In the control group, two out of 10 children after 15 days from the start of neurotropic therapy developed eye movement coordination, a stable reaction to tracking objects, and stable gaze fixation; in the remaining 8 children, these reactions appeared only 5 months after the start of treatment. Conclusion. Neuro-visual light stimulation, as an addition to pharmaconeuroprotection, significantly reduces the time for the formation of normal visual functions in case of DVM.
