Anti-inflammatory treatment after selective laser trabeculoplasty: a systematic review of the literature and meta-analysis of randomized control trials

Abstract

We assessed the effects of anti-inflammatory treatment after selective laser trabeculoplasty through a systematic search of the MEDLINE, COCHRANE, and ClinicalTrials.gov. The outcome measures were intraocular pressure, anterior chamber inflammation, and discomfort. Evidence synthesis was performed using fixed effects or random-effects model according to the heterogeneity of the included studies. Heterogeneity was assessed using Q-statistic and I 2 . For an overall estimate of continuous outcomes, the mean differences and their 95% confidence intervals were applied, while odds ratios and their 95% confidence intervals were applied for dichotomous outcomes. Six studies were included in all. No significant difference was noted in the patients for intraocular pressure and discomfort when treated with anti-inflammatory drops. However, the patients showed benefit from reduced anterior chamber inflammation in the first postoperative week [FE OR=0.43, 95% CI=(0.19, 0.95), P Q =0.97, I 2 =0%], with no significant difference between the outcomes of non-steroidal anti-inflammatory drugs and steroids [FE OR=0.75, 95% CI=(0.20, 2.82), P Q =0.37, I 2 =0%]. Anti-inflammatory drops reduce anterior chamber inflammation after selective laser trabeculoplasty but showed no effect on the intraocular pressure.
