方法：对83例行单眼外直肌后徙联合内直肌缩短的集合不足型外斜视患者手术前后的眼位、双眼视功能、进行回顾性总结和分析。斜视手术以单眼外直肌后徙联合内直肌缩短为主设计。术前有一级视功能患者如术后欠矫则进一步在同视机下行双眼融合功能训练。术后随访6～12(平均8)mo。

结果：术前视远平均外斜度为-35.6^△(-15^△～80^△)，视近平均外斜度为-56.5^△(-30^△～-95^△)； 术后视远平均外斜度为-6.5^△(+11^△～-19^△)，视近平均外斜度为-13.2^△(+9^△～-20^△)，术后视远视近斜视度与术前视远视近斜视度的比较差异有统计学意义(P=0.000)，术前双眼视功能和术后双眼视功能比较差异有显著性，术后远期视远视近外斜度的差值明显降低，平均斜视度差值从术前的19^△下降到术后的5.5^△(P=0.000)。

结论：集合不足型外斜视患者行单眼外直肌后徙联合内直肌缩短； 术后如双眼视功能进一步恢复则术后远期效果较好，回退率较低。

METHODS: We retrospectively reviewed and analyzed the eye position and binocular vision of 83 routine monocular rectus shortened convergence insufficiency exotropia patients before and after surgery. The strabismus surgery was mainly monocular lateral rectus, medial rectus recession combined shorten-based design. The postoperative such as nndercorrection to binocular vision training until his eyes Ⅱ grade recovery of visual function the same as the machine further downstream. The postoperative follow-up time was 6-12 months, an average of eight months.

RESULTS: The preoperative averagefar outer slope was -35.6^△(-15^△ - 80^△)and the average outside near slope was -56.5^△(-30^△--95^△), postoperative average far outside slope was -6.5^△(+11^△--19^△), the near average outer slope was -13.2^△(+9^△--20^△), the difference between preoperative and postoperative hyperopia near strabismus was statistically significant(P= 0.000), preoperative and postoperative binocular vision binocular function was significantly different, the difference between long-term postoperative hyperopia near the outer slope significantly reduced, the average difference of the degree of strabismus reduced from 19^△ to 5.5^△(P=0.000).

CONCLUSION:Convergence insufficiency exotropia underwent monocular rectus recession combined with medial rectus muscle shortening; such as binocular function after further recovery postoperative long-term effect is better, the rollback rate is lower.
