Abstract

Peripheral Hyperopic Defocus has been implicated for myopia progression in children. We did a study with peripheral refraction aid to compare the peripheral refraction in progressive (PM) (n=88) and non progressive myopic (NPM) (n=86) children.
Myopia progression was defined as increase in power by -0.5 Diopter per year or increase in axial length of 0.2 mm per year. A total of 174 children (only right eye) were included in the study.
The mean temporal central and nasal refraction of PM group was -3.6 +/- 2.8, – 4.3 +/- 3.1 and -3.8 +/- 3.4 D & in NPM group was -3.5 +/- 1.8, – 3.8 +/- 2.3 and -3.4 +/- 2.4 D
The p value was significant temporal to central refraction in the progressive myopia group. The peripheral refraction was hyperopic in the PM group compared to NPM group
