1. INTRODUCTION
Refractory glaucoma, defined as glaucoma not responsive to medical therapy and/or conventional filtration surgery, can be a management challenge. In addition to trabeculectomy
with adjuvant antifibrotic agents (1,2) and cyclodestructive procedures (3,4), glaucoma
drainage implant (GDI) surgery has emerged as a management option in these difficult
cases (5-7).
