Effect of Lens-Induced Myopia on Visual Cortex Activity: A Functional MR Imaging Study

Myopia is a type of refractive error that blurs retinal image and in turn can change neural signals transferred from retina to visual cortex. The purpose of this study was to evaluate the effect of induced myopia on occipital visual cortex activity by fMRI results. BOLD fMRI was performed in 13 emme...
