对50名视野缺损患者,在相同条件下间隔一小时用双盲法由两名医师分别行视野检查,然后用Estefman氏法定量分析视野缺损。通过定量对比发现大部分患者前后两次视野检查结果存在差异,未超过10个格子者应认为是“可允许的波动”。 Fifty patients with visual field defects were examined by two physicians under double vision for one hour at the same conditions. The visual field defects were then quantitatively analyzed by Estefman’s method. By quantitative comparison found that most patients before and after the two visual field test results are different, not more than 10 grid should be considered “permissible fluctuations.”
