摘要

This study investigated whether a stroke patient with left hemianopsia, which was confirmed by the perimetric test, may also have hemineglect. The relationship between hemineglect and hemianopia in patients with right hemispheric stroke was evaluated. Eleven subjects with left unilateral neglect underwent three testing sessions separated in time. The three test sessions, including cancellation and static perimetric tests, were performed at approximately 3 months, 4 months, and 7 months post the onset of the stroke. For the cancellation test, patients were asked to circle 60 marks on the test paper, and the number of marks correctly circled was scored. For the visual perimetry test, the visual field of each eye was divided into 59 spots (118 locations per patient). Absolute blind spots were subtracted to yield a final score. The correlation between the cancellation and static perimetric scores showed a statistically significant positive correlation (r=0.60, p＜0.0005). Perimetry is commonly employed to determine the presence of hemianopia. The results suggest, therefore, that hemianopia may be associated with existing hemineglect. It is suggested that rehabilitation team members should carefully identify this problem in order to treat the patient appropriately.
