Meta-analysis of mTLT compared to CW-TSCPC in IOP reduction at various follow-up visits. A total of 113 patients treated with mTLT and 225 patients treated with CW-TSCPC were included. No significant difference was observed at 1–2 weeks, 1 month, 3 months, and 6 months after the operation, but there was with high heterogeneity. At 12 months, the IOP reduction in mTLT was inferior to that in CW-TSCPC (WMD=-0.55, 95% CI -0.82 to -0.28)
