Visual Field Defects


(Depending on size)

  • A variety of retinal or more central pathologies can cause visual field deficits that are limited to particular regions of visual space.
  • By identifying visual field defect patterns, it is possible to determine the anatomical location of the source of visual loss.
  • Damage to the retina or one of the optic nerves before it reaches the optic chiasm results in a loss of vision that is limited to the eye of origin, while damage in the region of the optic chiasm or farther back in the brain will involve the visual fields of both eyes.
