Abstract:
Objective:To analyze the detection of myopic anisometropia in children of low and high age groups in a Class Ⅲ Grade A hospital to provide a theoretical basis for health promotion and education of myopia.Methods:A total of 217 children with myopia who were treated in the Ophthalmology Myopia Clinic of Beijing Tongren Hospital, Capital Medical University were selected from October to December 2020. According to age, they were divided into the low-age group (5-9 years old, 127 cases) and the high-age group (10-14 years old, 90 cases). The difference of spherical equivalent (SE) between left and right eyes of subjects was recorded, and the SE difference greater than or equal to 1.00d was defined as anisometropia. Non-parametric test was used to compare the difference of SE between the two groups, χ 2 test was used to compare the difference of gender and anisometropia detection rate between the two groups and multiple linear regression was used to analyze effects of age, gender and ocular axis difference on SE difference. Results:The binocular SE difference was 0.25 (0.00-0.50) D in the low age group and 0.50 (0.22-0.75) D in the high age group, and the difference between the two groups was statistically significant ( Z=2.75, P=0.006). The detection rates of anisometropia in the low-age group and the high-age group were respectively 9.45% and 20.00%, and the difference between the two groups was statistically significant (χ 2=4.92, P=0.027). Age had a significant effect on the SE difference. With the increase of age, the SE difference of both eyes increased 0.04 D/year (95% CI: 0.007-0.080, P=0.020). The binocular axial difference has a significant effect on the SE difference. For every 1 mm increased in the axial difference, the SE difference increased by 0.03 D (95% CI: 0.004-0.060, P=0.024). Gender had no effect on binocular SE difference ( P=0.382) . Conclusions:With the increase of age, the refractive difference of both eyes increases significantly, especially the incidence of anisometropia over 10 years old is higher than that under 10 years old. It is suggested that more attention should be paid to the occurrence of anisometropia in ophthalmology clinic, and to promote the early detection, intervention and control of anisometropia in children and adolescents.
