Abstract Details

Purpose:

To evaluate ocular biometric distribution and correlation with life style of the fifth and the sixth grade elementary school children in Jeju island.

Setting:

Cohort study in 6 elementary schools in fifth and the sixth grade elementary school children in Jeju island.

Methods:

600 children in 6 elementary schools were enrolled for cohort study. Questionnaire for life style, TV watching time, smart phone and computer watching time, outdoor activity, parental myopia, and average homework (book reading) time was made. Age (month), and height, and body weight was measured. Ocular biometric factors about axial lenth, corneal curvature were measured using IOL master®. Emmetropic IOL power using Haigis formula was made.

Results:

Outdoor activity, homework time, and computer time were all positively correlated. Low emmetropic power was significantly correlated with maternal myopia. Axial length was significantly correlated with paternal and maternal myopia. Keratometry alone did not show any significant correlation with parental myopia. Axial length was positively correlated with age (months) but keratometry did not. Mean axial length was 23.81mm and mean keratometry was 43.08 D. Mean WTW was 12.20 mm, and average IOL power for emmetropia was 20.97 D.

Conclusions:

We could find average biometric factors for the fifth and the sixth grade elementary school children in Jeju island, and could suggest that maternal genetic factor may work for myopia in Korean children.
