目的探讨间歇性外斜视术前立体视状况与手术量的关系。方法回顾分析47例常规手术量矫正的间歇性外斜视患者的术前远近立体视觉及术后眼位,与16例术前有远立体视并采用调整手术量患者手术后眼位对比研究。结果回顾性资料中,术前无立体视觉和只有近立体视觉的患者,其术后正位率,二者差异无统计学意义(P>0.05)。而术前有远立体视者,其术后正位率与术前无立体视及只有近立体视者差异均有统计学意义(P<0.01)。研究资料中,术前有远立体视觉的26例患者均在常规手术量的基础上适当减少手术量,术后眼正位率,与术前无立体视及仅有近立体视而采用常规手术量的患者相比较差异均无统计学意义(P>0.05)。结论术前有远立体视的间歇性外斜视,适当减小手术量,不影响手术成功率。
Objective To investigate the relationship between the status of stereopsis and the amount of surgery before intermittent exotropia. Methods Retrospective analysis of 47 cases of conventional esophageal surgery for patients with intermittent exotropia preoperative distance and ocular vision and postoperative ophthalmology, and 16 cases of preoperative stereopsis and surgery to adjust the amount of ophthalmic surgery patients compared. Results In the retrospective data, there was no significant difference in the postoperative positive rate between patients with and without stereopsis before surgery (P> 0.05). The preoperative stereopsis, the postoperative orthographic rate and no stereopsis and only stereopsis were statistically significant (P <0.01). Research data, preoperative stereopsis of 26 patients were based on the conventional amount of surgery based on the appropriate reduction in the amount of surgery, postoperative orthographic rate, with no preoperative stereopsis and only stereopsis and only the use of conventional surgery There was no significant difference between the two groups (P> 0.05). Conclusions There is far stereotactic intermittent exotropia preoperatively, to reduce the amount of surgery, does not affect the success rate of surgery.
