![]() The experiments consisted of two squares (6.5 radius. Following these groups and AC longitudinally enabled novel understanding of the joint influence of monocular vision and VPT birth on neurodevelopment. Materials Experiments were designed using Psykinematix Visual Psychophysics 1.4 software 14. ![]() Functionally, AC displayed normal visual acuity and form perception, but naso-temporal bias in motion perception. AC’s ON exhibited significant atrophy ipsilateral to the anophthalmic eye. compared to only 6 for Mac finder With the release of MAC OS X v 10 Psykinematix is an advanced OpenGL-based Software Package for Visual Psychophysics. Complete lack of binocular input would be responsible for these early deficits compensatory mechanisms may facilitate structural improvement over time. for the iPad/iPhone/iPod Touch platform, that are spin-off products of Psykinematix, our Mac OS X flagship product in the field of Visual Psychophysics. AC showed greater deficits in FA and AD bilaterally, but recovered towards VPT group means from 4 to 8 years-of-age. This extends the literature on altered white matter development in VPT children, being the first longitudinal study showing stable group differences across the 4, 6 and 8 year timepoints. Significant group differences in FA and AD were found bilaterally in the OR and PLIC. ![]() The diameter of the optic nerves (ON) were analysed using T1-weighted images. DTI images (N = 168) of the optic radiation (OR) and a control track, the posterior limb of the internal capsule (PLIC), were analysed. VPT-born neonates (<32wks gestational age), including the infant with unilateral anophthalmia, underwent neuroimaging every two years from birth until 8 years. Longitudinal comparison of white matter development in an anophthalmic (AC) very preterm (VPT) child with both binocular VPT and full-term (FT) children provides unique insights into early neurodevelopment of the visual system. Anophthalmia, characterized by the absence of an eye(s), is a rare major birth defect with a relatively unexplored neuroanatomy.
