유전적 요인이 어린이 시력에 미치는 영향 = Effects of Genetic Factors on children's visual acutiy

다국어 초록 (Multilingual Abstract)

This research was carried out to investigate the effects of genetic factors on Korean children's unaided visual acuity and to determine the visual acuity and objective refraction error.
The unaided visual acuity and objective refraction error were measured by the TOPCON chart projector and refractometer on 147 kindergarteners and 233 primary school children ranging from age 5 to 12. As well the effects of genetic factors on these children's were analyzed by human monitoring.
The results were as follows. :
The measurements on the unaided visual acuity of children were 3% for below the 0.1visual acuity, 9% for 0.1∼0.4, 18% for 0.5∼0.7, 16% for 0.8∼0.9, and 54%for over 1.0 visual acuity respectively.
The refractive errors were 9.35% for mixed astigmatism, 14.5% for hyperopia, 75.88% for mypia, and 0.27% for emmetropia, respectively.
When analyzing the hereditary factors, the relationship between the children and their parents those who wore glasses and those who did not and the children and their parents who wore glasses the child's visual acuity, is likely to be of a lower visual acuity than those chilren whose parents did not wear glasses.
From the relationship between their sisters and brothers who wore glasses or not and the children's visual acuity, the visual acuity of children whose sisters and brothers wore glasses were worse than the ·visual acuity of children whose sisters and brothers did not wear glasses.
