AIM: To observe the postoperative recovery of binocular vision after convergence insufficiency exotropia and regression of eye position.

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.
