Effects of damage to visual pathways on visual cortex before and after gamma knife radiosurgery

Takeaway

  • Damage to visual pathways caused by suprasellar tumors leads to reduction in gray matter density in visual cortex; however, the reduction is not reversed by gamma knife radiosurgery (GKRS).

Why this matters

  • It is unclear whether damage to visual pathways caused by suprasellar tumors leads to changes in visual cortex and whether the changes, if any, can be reversed by GKRS.
