Abstract:
AIM: To explore the efficacy of bilateral lateral rectus recession in the treatment of basic intermittent exotropia. METHODS: A prospective study was conducted on 104 patients with basic intermittent strabismus admitted to our hospital from October 2022 to October 2023, patients were randomly divided into a study group of 52 cases and a control group of 52 cases using a random number ranking method. The control group received unilateral recess-resect, while the study group received bilateral lateral rectus recession, the differences in surgical success rate, postoperative strabismus, and postoperative exotropia drift were compared between two groups.RESULTS: There was no statistically significant difference between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05). The strabismus in the 6 m and 33 cm eye positions at 1, 3, and 6 mo after surgery were lower than those at 1 d after surgery(all P<0.05). However, there was no statistically significant difference in the strabismus in the 6 m and 33 cm eye positions between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05), and there was statistical significant difference between the two groups in exotropia drift at different postoperative time points(all P<0.05). The exotropia drift of both groups increased at 3 and 6 mo after surgery compared to 1 mo after surgery, and the exotropia drift at 6 mo after surgery was greater than that at 3 mo after surgery(all P<0.05). However, the exotropia drift of the study group at 3 and 6 mo after surgery was lower than that of the control group(all P<0.001). CONCLUSION: Bilateral lateral rectus recession for the treatment of basic-type intermittent exotropia effectively reduces the amount of postoperative exotropia drift, and it has better long-term stability.
