Annual Changes in Refractive Errors and Ocular Components before and after the Onset of Myopia in Chinese Children
Xiang F et al. – Before the onset of myopia, axial elongation and progression accelerate. After a myopic refraction is established, axial elongation and progression decrease. The authors suggest that the increases before myopia may be due to increased intensity of study and decreased time outdoors. In contrast, the rapid slowing after the onset of myopia may represent an inhibitory effect of myopic defocus on eye growth.
