Denas preventive therapy in patients of school age with risk of myopia development and progressing

Concept of school myopia became wider in the last years. Myopia develops at the age of 5-
Thus, there is obvious influence of excess visual load on spasm of accommodation appearance and myopia progression. At the same time, number of patients with high myopia degree does not increase significantly. Myopia of low and medium degree without serious changes in a retina could be found more frequently. This fact is an evidence of an acquired character of myopia.
Several factors could explain mechanism of such myopia development:
It makes sense to carry out a preventive therapy of children during the period of asthenopic complaints appearance due to high possibility of myopia development in a definite group of children that present a risk group (age, intense study, incorrect posture, susceptibility to frequent catarrhal illnesses, etc.)
The most effective and safe is therapy by means of physiotherapeutic procedures. Methods of magnetotherapy, electrophoresis and laser therapy have positive but very short-
Prescription of mydriatics is effective enough (iriphryn 2.5%), they relax ciliary muscle. However, this muscle will spasm later if not trained. Special exercises for eyes gives a positive effect but it should be done regularly. Therewith, infancy habits should be taken into consideration. Some diligence is required; unfortunately, it is impossible to control correctness of its application.
Dynamic electroneurostimulation method has been applied in ophthalmology since recent times. Numerous previous researches are the evidence of that fact that multilevel reflex and neurochemical reactions that start up a cascade of regulatory and adaptive mechanisms of the body underlie a therapeutic action of dynamic electroneurostimulation (DENAS). As a result, pain syndromes are eliminated, blood flow is improved, anti-
The purpose of this work is to study an effectiveness of preventive DENAS in children of infancy with risk of myopia progression.
Group of patients with myopia of low and middle degree in the age interval from 7 to 16 years old was chosen. There were 48 patients altogether. This group was using DENAS method in 15 sessions course in a “Therapy” mode at 77 Hz frequency at minimal comfortable level of intensity. Duration of session was 10 minutes. Duration of follow-
Group of patients with myopia was observed during 2-
Asthenopic complaints were eliminated in 90 % of cases at the end of therapy. No side effects or complications were noticed during DENAS application. Therapeutic effect remained in average during 3-
Thus, DENAS application for prophylaxis of myopia of low and medium degree development and therapy has an evident therapeutic effect. Course duration is about 10 to 15 days. It is necessary to select repeated courses individually and in accordance with asthenopic complaints of patients appearance and clinical examination results. Refractometry and accommodation reserve determination should be considered as main diagnostic methods. Preventive character of DENAS application provides myopia stabilization. It is reasonable to apply it in groups with increased risk of myopia progression.
