Optic radiations(OR), which connecting the lateral geniculate nuclei and visual cortex, plays a critical role in visual function. Detailing the maturation process of OR is helpful in understanding the visual development and identifying the abnormalities. Diffusion tensor imaging can quantify the brain white matter development. Using DTI-based automating fiber-tract quantification, this study explored the spatiotemporal OR changes in children aged 3-13 years. Results indicated that the anterior, middle, and posterior segments of OR showed asynchronous developmental patterns. Specifically, the mid-segment of OR presented more mature than the anterior segment, while right OR showed more extended mature than left OR.
