【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(P0.05);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(P0.05);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(P0.05);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 effect of stereo vision and postoperative eye position change factors after intermittent exotropia surgery. Methods the First Affiliated Hospital of China Medical University from January 2010 to December 2014 of ophthalmic patients with intermittent exotropia in 70 cases, according to the pre-operative measurement results far strabismus surgery with non dominant extraocular rectus recession or lateral rectus recession combined with medial rectus according to the operation. Preoperative have near stereopsis and operative age, age of onset, oblique angle, were observed before and after the operation of the binocular visual acuity, refractive status, stereo vision, strabismus angle and eye position changes. The results compared with the preoperative, postoperative with stereo vision were significantly increased (P0.05) with the age of 9 years; surgery group, surgery group of patients younger than 9 years of stereo vision recovery and orthophoric rate were also significantly increased (P0.05); with the age of 9 years old group, onset age younger than 9 years old group Patients with stereo vision recovery and orthophoric rate showed no significant difference (P0.05); compared with the deviation less than 45 delta delta group, 45 groups of patients stereo vision recovery rate and orthophoric rate were not statistically significant. Conclusion the surgical treatment of intermittent exotropia can effectively improve the stereo vision, restore the operation effect of compound eye. Related with the age of surgery, patients with intermittent exotropia visual development period after stereo vision recovery rate is high. Early surgical strabismus, regardless of size, are conducive to the recovery of stereopsis.

【正文快照】： 间歇性外斜视是临床上常见的一种过渡性斜视,尤以儿童发病率较高。发展早期可能呈现外隐斜,最终有可能发展为恒定性外斜视。目前其发病机制尚不十分明确,患病早期因无明显症状或因患者年龄较小往往不易被发现,如果不及时采取措施,最终可能破坏双眼单视功能,形成恒定的外斜视
