One hundred and thirty patients of cerebrovascular accidents were subjected to a visual field examination using a Static Campimeter and a Goldmann perimeter. Thirty seven cases of homonymous field defects were detected; right homonymous field defect in 12 and left one in 25 subjects. The clinical diagnosis in this series was as follows; 11 putaminal hemorrhage, 6 thalamic hemorrhage, 4 internal carotid artery occlusion, 7 middle cerebral artery occlusion, 5 posterior cerebral artery occlusion, 2 subcortical hemorrhage and 2 cerebral infarction of uncertain location.
In general, the main arterial branch occlusion revealed congruous visual field defects with steep margins, whereas cerebral bleeding showed various types of field defects.
Middle cerebral artery occlusion showed quadrantanopia of various degrees and thalamic hemorrhage showed small homonymous field defects within one quadrant.
Macular sparing is of little value in topical diagnosis in this series.
