DETERMINANT FACTORS CORRELATE TO MYOPIA

Abstract

Background: Myopia is the most common refractive error and easily correctable with optical devices. Myopia has been roughly classfied by degree of severity. Low myopia usually describes myopia of 3 diopters or less. Medium myopia usually describes myopia between >3 and 6 diopters. High myopia usually describes myopia of more than 6 diopters. The global prevalence of refractive errors has been estimated from 800 million to 2.3 billion. The incidence of myopia within sampled population often varies with age, country, sex, race, ethnicity, occupation, habits, environment, and other factors. The aim of this research is to know the correlation between determinant factors with myopia. This study used questionnaire of 14 questions as instruments.

Method: This research is an cross sectional observational research with dependent variables are genetic, habits, environment, parents salary and the father’s educationr. The independent variable is the classification of myopia. The respondent in this research is 59 student of senior high school2 in Palembang. Univariat and bivariat analysis were performed by Chi-Square (X2).

Result : There are a total of 59 students participated in this study. From the statistic experiment using Chi Square (α < 0,05 ), environment (p value=0.031), habits (p value= 0,018), have associated with students myopia. There aren’t correlation between genetic( p value:0,347), father’s education (p value= 0,088), and for parents income (p value: 0,145) with myopia.

Conclussion: determinant factors correlate to myopia are environment factor and habits factor
