一条或一组垂直肌麻痹可引起眼球旋转位异常,即内旋斜或外旋斜。旋转斜可由间接检眼镜检查或眼底摄影检查和许多主观试验进行诊断,主观试验中,最常用的是 Maddox 双杆试验。单侧上斜肌麻痹,Maddox 试验想必是显示出麻痹眼的外旋转,然而在一部分病人Maddox 试验却显示出非麻痹眼的外旋转偏 One or a group of vertical muscle paralysis can cause eye rotation abnormalities, that is, within the rotation ramp or external rotation. Rotational tilt can be diagnosed by indirect ophthalmoscopy or fundus photography and by many subjective tests, the most commonly used of which is the Maddox double-rod test. Unilateral supraspinal paralysis, Maddox test must have been shown to be outside the rotation of the paralyzed eye, however, in some patients Maddox test showed non-paralyzed eye outside the rotation deviation
