Abstract
Objective To compare the efficacy of selective laser trabeculoplasty ( SLT ) versus prostaglandinanalogue ( PGA) in the treatment of open angle glaucoma ( OAG) and ocular hypertension ( OHT) . Methods Literature analysis.Systematic review of randomized controlled trials comparing SLT versus PGA , identified by searching literatures including Medline (January,1966-December, 2012), EMBASE Reviews ( January , 1974-December , 2012 ) OVID Evidence-Based Medicine Reviews ( January , 1966-December , 2012), Chinese BioMedical Literature Database SinoMed (January,1966-December, 2012), and CNKI (January,1999-December, 2012).RevMan 5.0 was used to do meta-analysis.Results Three publications reporting 3 trials, 161 participants ( 231 eyes ) with OHT or OAG were included for meta-analysis.IOP reduction favored PGA group,weighted mean difference (WMD) =-0.85 [1 mmHg=0.133 kPa;95%confidence interval (CI) ( -1.43 to -0.27), no significant heterogeneity present ( P =0.82, I2 =0%)].Success rates are equal in two groups [OR =0.70,95%CI =(0.49 to 1.19), no significant heterogeneity present (P=0.58,I2 =0%)].Eyes underwent additional antiglaumatous interventions favored SLT group,OR=1.11 [95%CI =(0.60 to 2.06), significant heterogeneity present, (P=0.08, I2 =61%) ].Conclusions As primary therapy of OAG or OHT , SLT is no more effective than PGA in success rate.IOP reduction affected by SLT is not effective than PGA.Compared with PGA , SLT can reduce the use of anti-glaucoma medications.
