Permanent homonymous hemianopias following migraine.
Two patients with migraine and repetitive visual field defects of homonymous hemianopic type are reported. The visual field defects were confirmed by Goldmann perimetry and automated static perimetry. Neither computed tomography nor magnetic resonance imaging showed abnormal findings. Decreased cerebral blood flow at the left basal ganglion area was the only abnormal finding detected in one patient by 123I-IMP (iodoamphetamine)-SPECT (single photon emission computed tomography), which is applicable to right homonymous hemianopia. A visual field test that includes the current automated static perimetry is important to the diagnosis and the subsequent treatment of patients with migraine, particularly those who have experienced visual negative phenomena.
