目的：测量先天性上斜肌麻痹患者其下斜肌异常的程度。方法：采用临床横断面研究，自身配对对照设计。选取30例合并单眼上斜肌麻痹的外斜视（间歇性外斜视、恒定性外斜视）患者做双眼外直肌后退和下斜肌减弱等相应的垂直肌手术时，观察患者麻痹眼和非麻痹眼的下斜肌，测量下斜肌的紧张度。下斜肌的紧张度是以斜视钩垂直于巩膜勾出下斜肌，肌肉离开巩膜的最大距离表示。结果：麻痹眼的下斜肌粗细不等，但都比健眼下斜肌坚韧、紧绷。麻痹眼的下斜肌平均紧张度为6．33±1．35mm，非麻痹眼的下斜肌平均紧张度为7．76±0．81mm，两者的差异具有统计学意义（P＜0．01）。结论：上斜肌麻痹时患眼的下斜肌紧张度较高、弹性较差。

AIM:To measure the abnormality of the inferior oblique tendon in patients with congenital superior oblique muscle paralysis. METHODS: In this cross -sectional, self -control designed study, the tensity of the inferior oblique tendon of both the paralytic and nonparalytic eye were measured during the operations in 30 patients who were diagnosed with exotropia ( including intermittent exotropia and constant exotropia ) accompanied with single superior oblique muscle paralysis.The tensity of the tendon was measured as the maximal distance of which the inferior oblique tendon could be lifted from the sclera RESULTS: Inferior oblique had different degrees of thickness, but was tougher and tighter than that of nonparalytic eye.There was a significant difference ( P<0.01) in the average tensity of the inferior oblique tendon between the paralytic eyes 6.33 ±1.35mm and the nonparalytic eyes 7.76±0.81mm. CONCLUSION: The inferior oblique tendon is stronger and less relaxant in the paralytic eyes.
