Структура клинической рефракции глаз у детей подросткового возраста

Abstract

Purpose. To analyze the frequency of myopia in the structure of clinical eye refraction in adolescent children. Material and methods. Analysis of the results of an ophthalmological examination of 690 schoolchildren aged 11, 13, 15 years using the continuous sampling method. Results. In the structure of totality of the examined children, refractive errors were noted in 405 people (58.7 %), in the structure of myopia refractive error amounted to 339 people (83.7 %). 65.5 % of schoolchildren had mild myopia, 37.5 % had moderate myopia, and 1.8 % had high myopia. In 32 schoolchildren habitually excessive tension of accommodation was revealed. The progressive course of myopia was noted in 45 children (13 %), of which in half of the cases it was at the age of 11 years. According to the picture of fundus, the chorioretinal form of myopia predominated. In the structure of refractive errors, corneal astigmatism was detected in 118 children (29 %), of which in 55 % of children it was myopic, in 22 % it was mixed. 201 schoolchildren had incomplete vision correction due to refractive amblyopia, in 90 % of cases it was of a weak degree. Conclusion. In the structure of clinical refraction of the examined children, 285 (41.3 %) schoolchildren had emmetropia, 405 (58.7 %) schoolchildren had refractive errors. Of the entire set of refractive errors, myopia occurred in 339 people (83.7 %). Mild myopia occurred in almost half of the total population of pupils (62.5 %) of age from 11 to 15 years. There is a tendency to increase myopic refraction from 11 to 15 years of age. Keywords: refraction, myopia, childhood, morbidity
