目的:探讨先天性上斜肌麻痹患者手术后双眼视功能变化。方法:先天性上斜肌麻痹患者28例手术前、后分别行斜视度和双眼视功能检查,统计分析其变化。结果:术后正位率89.3%。手术后有同时视、融合和立体视的患者分别增加9,13和13例,与术前相比差异具有显著性(P<0.05)。近立体视觉有明显改善。术前斜视度小、视力好且有融合功能的患者术后双眼视功能恢复好。结论:先天性上斜肌麻痹手术治疗在改善眼位的同时,双眼视功能部分得以重建。视功能恢复与视力、斜视度及有无融合功能有关。

AIM:To investigate the postoperative changes of binocular visual function in patients with congenital superior oblique palsy.METHODS:Eye position and binocular visual function were examined in 28 patients with congenital superior oblique palsy pre-and post-operatively. The results were statistically analyzed.RESULTS:The normal eye position rate after operation was 89.3%. There were 9 patients who gained simultaneous perception after operation,while 13 patients gained fusion as many as that gained stereoacuity. There was statistically significant difference between postoperative and preoperative eyes (P<0.05). Near stereoacuity was improved after operation. Patients who had better visual acuity and low strabismus degrees as well as fusion had a better recovery.CONCLUSION:The operation could improve the eye position and rebuild the binocular visual function of the congenital superior oblique palsy. The recovery of binocular visual function was related to visual acuity and strabismus degrees of the patients and whether they had fusion function. 
