Post Penetrating Keratoplasty Glaucoma: An Overview

Abstract

Glaucoma is the leading cause of blindness after penetrating keratoplasty (PK) and its management is still controversial. Earlier diagnosis is mandatory to salvage the graft. The newer modalities like recent tonopens, ultrasound biomicroscopy (UBM), Anterior segment optic coherence tomography (ASOCT) are helpful tools for its diagnosis. Recent developments in its management includes newer drugs, surgical procedures such as trabeculectomy with mitomycin-C, glaucoma drainage devices (GDD), and cyclodestructive procedures with Nd: YAG (neodymium: yttrium-aluminium-garnet) and diode lasers. Despite all these advances the risk of graft failure continues to be high.
