Survival analysis for success of Molteno tube implants

Abstract

AIM To apply survival analysis in assessing the long term outcome of Molteno tube implantation and to identify risk factors for failure. METHODS A retrospective, 10 year, consecutive case series study of 119 eyes that underwent implantation of a Molteno tube. The main outcome measures considered were intraocular pressure (IOP), visual acuity, and complications. RESULTS A 30% or greater reduction in IOP was achieved in 68.9% of cases. However, the overall, “complete success” rate (IOP CONCLUSIONS In eyes at high risk of trabeculectomy failure, implantation of an aqueous shunt device should be considered. Pseudophakia should be considered an additional risk factor for failure. Early failure appeared relatively more common but long term follow up of all cases is recommended to ensure adequate management of late failures.
