Abstract:
Objective To compare the efficacy between slanted bilateral lateral rectus recession(S-BLR)and conventional bilateral lateral recession(C-BLR)procedure in the treatment of convergence insuffi-ciency-type intermittent exotropia.Methods Relevant studies published before November 2023 were systematically searched in PubMed,Cochrane Library,EmBase,Web of Science,CNKI,Wanfang and VIP databases to compare the surgical effects of S-BLR and C-BLR,expressed by OR value and 95%CI.The success rate,recurrence rate,overcor-rection rate and stereoscopic improvement rate were analyzed by random effects model.Results A total of 5 studies involving 296 patients were included in the analysis.The success rate of the S-BLR procedure was significantly higher than that of C-BLR(OR=4.06,95%CI:2.47-6.67,P＜0.001),patients subjected to the C-BLR pro-cedure were more likely to be recurrent(OR=0.21,95%CI:0.08-0.52,P＜0.001).No statistically signifi-cant differences in the combined results for overcorrection rates(OR=0.43,95%CI:0.07-2.52,P=0.35)and stereoscopic improvement rates(OR=0.82,95%CI:0.36-1.83,P=0.62)were present between the S-BLR and C-BLR procedures(P＞0.05).Conclusion S-BLR procedure has a higher success rate and a lower recurrence rate in patients with aggregation-deficient intermittent exotropia.
