目的 :探讨青少年共同性斜视术后眼位矫正偏差的发生原因和影响因素。方法 :对 88例共同性斜视手术后晚期存在眼位偏差的 19例患者分别进行了手术年龄、斜视类型、眼轴长度、术后时间及术眼视觉功能等方面的比较观察和临床分析。结果 :通过对本组的资料分析发现 ,年龄愈小发生术后眼位偏差的机会愈大 ;内斜以矫正过度多见 ,外斜以矫正不足多见 ;斜视术后眼球有向外侧偏移和眼球向术前回复的倾向 ;眼轴长度对术后眼位偏差没有显著影响 ;术后视觉功能 (立体视觉、屈光参差、弱视等 )正常与否对眼位偏差有着十分重要的影响。结论 :青少年共同性斜视术后的眼位偏差受多种因素影响 ,其中早期进行视觉功能检查、及时予以手术矫正 ,术后必要的患眼视觉功能 ,尤其是双眼的同视功能的建立是预防和减少术后眼位出现偏差最重要的步骤 Objective: To investigate the causes and influencing factors of orthodontic deviation after adolescent common strabismus surgery. Methods: Ninety-nine patients with deviation of ophthalmic position after the operation of common strabismus surgery were compared and analyzed respectively in terms of operation age, type of strabismus, length of axial length, time of postoperative operation and visual function of ophthalmology. Results: Through the analysis of this group of data found that the younger the smaller the risk of postoperative eye position deviation; Overtype more common overcorrection, Outer oblique to rectify the less common; Strabismus after the eye with lateral deviation and Eyeball preoperatively tend to return; ocular axial length had no significant effect on postoperative ophthalmic deviation; visual function (stereopsis, anisometropia, amblyopia, etc.) normal or not on eye position deviation has a very important impact. CONCLUSIONS: The deviation of eye position after adolescent common strabismus operation is influenced by many factors, of which early visual function test, timely surgical correction, postoperative visual function necessary for the eye, especially the establishment of the same-eye function of both eyes is prevention And to reduce postoperative deviation of the most important step of eye position
