VISUAL DISORDERS IN SCHOOLCHILDREN OF 8–12 YEARS OLD IN KAUNAS CITY SCHOOLS
Aim. To evaluate the current epidemiology and risk factors for myopia in schoolchildren aged 8–12years. Methods. We evaluated visual acuity for 308 schoolchildren in Kaunas city schools. We used a Snellen eye chart, evaluated refraction, used a Lang stereo test. We did a questionnaire survey. Results. We identified 92 (30%) cases of visual disorders in schoolchildren. Myopia in the first group (age 8–10) and in the second group (age 10–12) was diagnosed for 23.3% (n=42) and 39.7% (n=49) children respectively, the results in the second group were statistically significant higher p<0,05. In both children groups, there were 73.6% (n=67) low degree (0–3D), 17.6% (n=16) moderate degree (3–6D) and 8.8% (n=8) high degree (>6D) myopia. There were 92 children (58.8%), who had eye fatigue symptoms, such as watery or red eyes, increased sensitivity to light. Conclusion. The most frequent vision disorder was low degree myopia. Genetics and comorbidity were not statistically significant for myopia. Most of the children have eye fatigue symptoms.
