Abstract
|
|
|
Purpose: This study was conducted to recognize the necessity of a eye healthcare and eye care management through the prevalence of astigmatism and astigmatic refractive power in growing children and youth.
Methods: Study subjects were 5 to 18 years old 280 persons of the Korean National Health and Nutrition Examination Survey document 2010. The data were analyzed with comparative analysis on correlation of prevalence of astigmatism, astigmatism power, astigmatism axis, spherical refractive power and cylinder refractive power by SPSS ver18.0.
Results: According to classification of age group, the prevalence of astigmatism was 50.0% in 5-6ages, 33.8% in 7-9ages, 48.8% in 10-12ages, 67.7% in 13-15ages, 63.4% in 16-18ages, Corrected vision was 0.93 when spherical refractive was bigger than astigmatic refractive power and corrected vision was 0.83 when astigmatic refractive power was bigger than spherical refractive in less than C-1.00D. Astigmatic refractive power influenced more than spherical refractive power with corrected vision.
Conclusions: It is needed to recognize the importance of the increase and prevalence of astigmatism, it is necessary for preventing worsen visual acuity and promoting eye health welfare to have more social interests and provide systematic devices.
