  • Abstract
  • Look Inside

A 55-year-old male presented with blurring of vision in both eyes. He had suffered from cerebral hematoma following traffic accident two months before. The corrected visual acuity was 20/40 in either eye. Perimetry showed typical binasal hemianopsia. The right eye showed pale optic disc. Glaucomatous disc cupping was present in both eyes. Magnetic resonance imaging (MRI) showed hematoma in the right frontal and temporal lobes with deviation of the optic chiasm and infundibulum to the left. The binasal hemianopsia appeared to be the consequence of pressure to the optic chiasm by the hematoma and of counter pressure by the left carotid artery.
