Effect of lens-induced myopia on visual cortex activity: A functional MR imaging study

Abstract

BACKGROUND AND PURPOSE: 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. MATERIALS AND METHODS: BOLD fMRI was performed in 13 emmetropic volunteers (refractive error,
