摘要: 目的 探讨间歇性外斜视手术前后立体视觉及术后眼位变化的影响因素。方法 选择 2010 年 1 月至 2014 年 12 月中国医科大学附属第一医院眼科间歇性外斜视患者 70 例,根据术前视远斜视度测量结果设计手术,采用非主导眼外直肌后徙或外直肌后徙结合内直肌缩短术。依术前有无近立体视及手术年龄、发病年龄、斜视角,分别观察手术前后双眼的裸眼及矫正视力、屈光状态、立体视觉、斜视角度及眼位等的变化。结果 与术前比较,术后具有立体视觉者显著增多(P < 0.05);与手术 年龄>9 岁组比较,手术年龄≤9 岁组患者立体视觉恢复率及眼位正位率亦显著升高(P < 0.05);与发病年龄>9 岁组比较,发病年 龄≤9 岁组患者立体视觉恢复率及眼位正位率无统计学差异(P > 0.05);与斜视度≤45△组比较,>45△组患者立体视觉恢复率及眼位正位率均无统计学差异。结论 手术治疗间歇性外斜视可有效提高立体视觉,恢复眼位。手术效果与手术年龄有关,视觉发育期的间歇性外斜视患者术后立体视觉的恢复率更高。斜视度无论大小,早期手术均有利于立体视功能的恢复。

Abstract: Objective To investigate the influencing factors of stereopsis and ocular position changes before and after intermittent exotropia surgery. Methods A total of 70 cases diagnosed with intermittent exotropia(squint angle >15△and < 85△)and treated in the Department of Ophthalmology,the First Hospital of China Medical University from January 2010 to December 2014,were enrolled for the study. Operation methods was designed according to the pre-operative apparent distant strabismus,and operations should be taken on the non-dominant eyes to lateral rectus recession combined with medial rectus shortening or lateral rectus recession. Patients were divided into different groups according to age,age of exotropia onset,the angle of squint. The outcomes included best corrected visual acuity of eyes,refractive status,stereopsis,squint angle position of eye with intermittent exotropia after surgery. Results Compared with preoperative status,the stereopsis symptom was significantly improved after surgery(P < 0.05). Stereopsis recovery and orthophoric rate were significantly increased according to the surgery age in children below 9 years old compared with those over 9 years old(P < 0.05). Compared with the group of age ≤9 years old,the rate of recovery of stereopsis and the rate of orthophoria were not statistically significant(P > 0.05). There was no statistical difference in the recovery rate of stereopsis and the orthostatic rate of eyes between the groups of 45△ and more than 45△. Conclusion Intermittent exotropia surgery can effectively improve the stereopsis and eye position,and the outcomes of surgery are related to the age of surgery. The recovery rate of stereopsis is higher in the patients with intermittent exotropia during the visual development period. Regardless of the size of the angle of squint,early surgery is benefit to the recovery of stereopsis.

Key words: intermittent exotropia, stereopsis, eye position, the angle of squint
