Abstract

The present study demonstrates alterations of the contralateral side optic tract to an optic nerve traumatic lesion. Visual acuity of the right eye following Traumatic optic neuropathy (TON) remained at 0 following the injury. Electrophysiological examination using pattern electroretinogram revealed values reduced by 50% in the right eye compared with the left eye. Pattern visual‑evoked potential evaluation indicated a bilateral lesion with a higher decrease following right eye stimulation. Magnetic resonance imaging revealed right optic nerve atrophy. Functional magnetic resonance imaging indicated decreased activity of the visual centre during left eye stimulation. The present study revealed contralateral visual tract alterations following unilateral injury, and hypothesize that the ganglion cells of the retina respond initially to glial activation. These changes are, in our view, followed by changes in the visual pathway.
