Quantitative analysis of the effect of near lens addition on accommodation and myopigenesis.

摘要: Purpose. To develop a quantitative, objective, and scientific basis for understanding the effects of applying near bifocal additions (ADDs) on oculomotor control myopia development. This is important because major public health problem that affects 25% U.S. population 75% or more in Asian countries. It also associated with an increased risk vision-threatening conditions, such as retinal breaks detachments, well glaucoma. Methods. A comprehensive model refractive error development was constructed based dual-interactive feedback accommodation vergence, which represented short-term dynamics pathway, addition both genetic environmental (defocus-induced axial growth) components long-term pathway. An alternating near- far-viewing paradigm simulated, varying amounts ADDs, to obtain parametric relationship between root mean square accommodative (AE) induced (IRE). The p...
