Clinical examination of saccadic eye movements in hemianopia.

We used two simple bedside tests of saccadic eye movements between two fingers as targets to study 23 hemianopic patients. With these tests, we could provide confirmation or, in malingering, exclusion of a hemianopia. Furthermore, the amount of ocular motor compensation for the loss of one half of the visual field could be estimated, and visual hemineglect was demonstrated. The findings in some cases with chronic homonymous hemianopia suggested "extrastriate vision."
