Development of the optic radiations and visual function after premature birth

Visual impairment in preterm infants at term equivalent age (TEA) is associated with impaired microstructural development in the optic radiation, measured as reduced fractional anisotropy (FA) by Diffusion Tensor Imaging (DTI). We tested the hypothesis that these abnormalities develop during the late preterm period. DTI was performed in 53 infants born at a median (range) of 30+1 (25+4–34+6) weeks post-menstrual age (PMA), 22 of whom were imaged...
