context_page_description: Hemianopsia, or hemianopia, is a loss of vision or blindness in half the visual field, usually on one side of the vertical midline. The most common causes of this damage are stroke, brain tumor, and trauma.
  Temporary hemianopsia can occur in the aura phase of migraine.

  Binasal hemianopsia – the loss of the fields surrounding the nose;
  Bitemporal hemianopsia – the loss of the fields closest to the temples.
