Polling JR, et al. - In the present study, the researchers sought to examine myopia progression in Europeans as a function of age and degree of myopia from the first prescription to final refractive error. The Drentse Refractive Error and Myopia Study evaluated data from a branch of opticians in the Netherlands from 1985 onwards in a retrospective study. In total, 2,555 persons (57.3% female) met the inclusion criteria. The trajectories of the natural course of myopia progression can serve as a guide to the management of myopia in European children. Spherical equivalent of refraction at 10 years is a significant prognostic indicator and can help assess the intensity of treatment.
