Glaucoma drainage implant exposure: A review of aetiology, risks and repair considerations.

Epidemiology & Genetics

Summary

Exposure of a GDI is a well-known complication, and prompt recognition and treatment are required to prevent endophthalmitis, a potentially blinding condition.

Abstract

In recent years, there has been a paradigm shift in glaucoma surgical procedures. Glaucoma drainage implant (GDI) surgeries are being performed much more commonly. Thus, it is important for surgeons to be cognisant of potential complications and their management. Exposure of a GDI is a well-known complication, and prompt recognition and treatment are required to prevent endophthalmitis, a potentially blinding condition. In this review, we discuss the mechanisms and risk factors for GDI exposure, highlight important considerations for repair, and discuss repair techniques, with the aim of improving patient outcomes and minimising the risk of re-exposure.
