Objective To evaluate the efficacy and tolerability of selective laser trabeculoplasty(SLT) and agron laser trabeculoplasty(ALT) in the treatment of open-angle glaucoma(OAG). Methods Pertinent studies were selected through extensive searches of PubMed, Cochrane Library, Embase, and meeting abstracts. Efficacy measures were weighted by mean differences for intraocular pressure(IOP) as well as change of number of glaucoma medications and relative risks(RR) for therapeutic IOP responses. Tolerability measures were RRs for adverse events. Pooled estimates were carried out in RevMan software 5.1. Results SLT was associated with a numerically lager but nonsignificant reduction compared with ALT , with a WMD 0.04 (95% CI, -0.61–0.69). Nor was there a significant difference in therapeutic IOP responses between SLT and ALT, with a pooled RR 1.01( 95% CI, 0.87-1.19). Patients who received SLT would took fewer glaucoma medications after operations than those who received ALT, with a WMD 0.29(95% CI, 0.01–0.56). When compared in patients with previous failed laser treatment, SLT was more effective in IOP reduction than ALT with a WMD 1.78(95% CI, 0.64–2.92).The frequencies of anterior chamber reaction and IOP peak after operation were similar comparing SLT and ALT, with pooled RRs of 0.90(95% CI, 0.74–1.10) and 0.89(95% CI, 0.44–1.80), respectively. Conclusions SLT was associated with IOP-lowering and therapeutic IOP responses efficacy comparable to that of ALT. But SLT would produce a lager reduction of number of glaucoma medications than ALT after operation and it appeared to be more effective for patients who had failed to respond adequately to laser treatment before. The difference of tolerability of the two lasers was not significant. |
