PURPOSE To determine whether fusional vergence adaptation in patients who can fuse in at least some gaze positions can cause curvature of the non-fixing eye movement paths of patients with apparent "overaction" or "underaction" of the oblique muscles, yielding possibly erroneous evidence of hypertonicity as the cause of the overaction or underaction. METHODS The authors retrospectively studied Lancaster red-green plots of patients with oblique muscle "overaction/underaction." If fusion was present, the plot had usually been repeated after monocular occlusion for at least 30 minutes. Fundus torsion and fusion status were also recorded. RESULTS After a patch test in patients displaying fusion, the non-fixing eye's movement path became more linear. CONCLUSIONS Although it has been argued that true overaction of the oblique muscles would show curved eye movement paths on side gazes, in the study patients displaying fusion in at least some directions of gaze, the eye movement paths became more linear after patch testing, favoring the more mechanical explanation. Illustrated cases were consistent with the hypothesis that short inferior oblique muscles simply hold the globes in extorted positions, and the appearance of inferior oblique muscle "overaction" arises from the eyes' following their extorted movement paths on side gazes, not from hypertonicity of the inferior oblique muscle in the adducting eye.

下斜肌“过度反应”是由下斜肌缩短引起的，而不是由高张性引起的。

目的 确定至少可以在某些凝视位置融合的患者的融合聚散度适应是否会导致斜肌明显“过度动作”或“动作不足”患者的非固定眼球运动路径弯曲，从而产生可能的错误证据高渗性作为过度作用或作用不足的原因。方法 作者回顾性研究了斜肌“动作过度/动作不足”患者的兰开斯特红绿图。如果存在融合，通常在单眼闭塞至少 30 分钟后重复该图。还记录了眼底扭转和融合状态。结果 在显示融合的患者中进行斑贴测试后，非固定眼的运动路径变得更加线性。结更机械的解释。图示的案例与以下假设一致，即短的下斜肌只是将眼球保持在扭曲的位置，并且下斜肌“过度动作”的出现是由于眼睛在侧视时跟随其扭曲的运动路径，而不是由于下斜肌的高渗内收眼的斜肌。[J 小儿眼科斜视。2022;59(1):28-34.]。在至少在某些凝视方向上显示融合的研究患者中，在斑块测试后眼球运动路径变得更加线性，有利于更机械的解释。图示案例与以下假设一致，即短的下斜肌只是将眼球保持在扭曲的位置，而下斜肌“过度动作”的出现是由于眼睛在侧视时跟随其扭曲的运动路径，而不是下斜肌的高渗内收眼的斜肌。[J 小儿眼科斜视。2022;59(1):28-34.]。在至少在某些凝视方向上显示融合的研究患者中，在斑块测试后眼球运动路径变得更加线性，有利于更机械的解释。图示案例与以下假设一致，即短的下斜肌只是将眼球保持在扭曲的位置，而下斜肌“过度动作”的出现是由于眼睛在侧视时跟随其扭曲的运动路径，而不是下斜肌的高渗内收眼的斜肌。[J 小儿眼科斜视。2022;59(1):28-34.]。下斜肌“过度动作”的出现是由于眼睛在侧视时跟随它们的扭曲运动路径，而不是由于内收眼下斜肌的高渗性。[J 小儿眼科斜视。2022;59(1):28-34.]。下斜肌“过度动作”的出现是由于眼睛在侧视时跟随其扭曲的运动路径，而不是由于内收眼下斜肌的高渗性。[J 小儿眼科斜视。2022;59(1):28-34.]。
