Abstract EN
The optic radiation (OR) is a visual neural fiber pathway for the transfer of visual information from the lateral geniculate body of the thalamus to the primary visual cortex.
To demonstrate the recovery of an OR injury, quantification and visualization of changes to the injured OR are necessary.
Diffusion tensor imaging (DTI) allows determination of the state of an OR by assessing the obtained DTI parameters.
In particular, diffusion tensor tractography (DTT), which is derived from DTI data, allows three-dimensional visualization of the OR.
Thus, recovery of an injured OR can be demonstrated by examining changes in DTI parameters and/or configuration on follow-up DTI scans or via DTT of the injured OR.
Herein, we review nine DTI-based studies that demonstrated recovery of OR injuries.
The results reported in these studies suggest that an OR injury has a potential for recovery.
Moreover, the results of these studies can form a basis for elucidating the recovery mechanisms of injured OR.
These studies have suggested two recovery mechanisms for OR injury: recovery via the original OR pathway or via the transcallosal fibers of the corpus callosum.
However, only nine studies on this topic have been conducted to date and six of those nine studies were case reports.
Therefore, further studies involving larger numbers of subjects and reporting precise evaluations of changes in OR injury during recovery are warranted.
