Effect of Internal Rectus Muscle Resection Combined with Posterior Migration of External Rectus Muscle in the Treatment of Intermittent Exotropia with Inadequate Collection
Objective To observe the effect of monocular internal rectus muscle resection combined with posterior migration of external rectus muscle in the treatment of ensemble deficiency intermittent exotropia(CI-IXT).Methods The clinical data of 104 patients with CI-IXT admitted to the author's hospital from January 2018 to January 2021 were retrospectively analyzed.According to different surgical methods,they were divided into control group(n=52)and observation group(n=52).The control group was treated with binocular posterior rectus muscle migration,while the observation group was treated with monocular internal rectus muscle resection combined with posterior rectus muscle migration.The eye position correction effect was compared between the two groups at 6 months after operation.The visual distance,visual proximity,mean strabismus,visual function,fusion function,incidence of complications and recurrence rate before and after operation were statistically analyzed.Results The orthostatic rate of the observation group was higher than that of the control group at 1 week and 3 months after operation,and the overcorrection rate was lower than that of the control group(P＜0.05).There was no significant difference in the undercorrection rate between the two groups(P＞0.05).There was no significant difference in orthostatic rate,overcorrection rate and undercorrection rate between the two groups at 6 months after operation(P＞0.05).6 months after surgery,the positive rate of grade Ⅰ visual function decreased in both groups,and the positive rate of grade Ⅲ visual function increased in both groups(P＜0.05),but there was no statistical significance in the positive rate of grade Ⅱ visual function compared with that before surgery(P＞0.05),and there was no statistical significance in the positive rate of grade Ⅱvisual function compared with that before surgery(P＞0.05).At 6 months after operation,the fusion range,collective fusion and discrete fusion of the two groups were increased(P＜0.05),but there was no significant difference between the two groups(P＞0.05).There was no significant difference in the incidence of complications between the two groups(P＞0.05).The recurrence rate of the observation group was lower than that of the control group(1.92%vs 13.46%)(P＜0.05).Conclusion Internal rectus muscle resection combined with posterior migration of external rectus muscle is effective in the treatment of CI-IXT,and the recurrence rate is low,which is worthy of clinical application.
