Re: Schlenker et  al.: Efficacy, safety, and risk factors for failure of standalone ab interno gelatin microstent implantation versus standalone trabeculectomy (Ophthalmology. 2017;124:1579-1588)

The article by Schlenker et  al1 retrospectively compares the outcomes of an ab interno gelatin stent to stand alone trabeculectomy in reducing intraocular pressure (IOP) in patients with uncontrolled open angle glaucoma. The article concludes that both procedures demonstrate equal efficacy and risk of failure. “Both proced ures had a 75% survival at approximately 10 months for complete success at an IOP ≤21 mmHg.” In terms of trabeculectomy success rates in this study these data seem to be suboptimal in comparison with recent trabeculectomy outcome data from the UK,2 where Kirwan et al demonstrated a 90% survival at 10 months for complete success at an IOP of ≤21 mmHg and a bleb needling revision rate of 17%, compared with 30.8%.
