Glaucoma Drainage Device (GDD) Implantation in Post Trabeculectomy Patients

Abstract

Objective: This study aims to report a case of Glaucoma Drainage Device (GDD) implant surgery in a patient who experienced an increase in Intraocular Pressure (IOP) after long term trabeculectomy. Case Presentation: A 58-year-old male patient came with complaint of blurred vision since two years ago. Patient did not complain of sore and red eyes. He was given 2 x 250 mg of Acetazolamide, 2 x 1 tablet of Aspar K, 2 x 1 right and left eye (RLE) of Latanoprost, and 2 x 1 RLE of Betaxolol HCl. The patient had glaucoma since 20 years ago and had undergone surgery in 2002 on the right eye and left eye surgery in 2004. His right eye intraocular pressure was 38 mmHg with conjungtival bleb (+) flat (+) minimal vascularity (+) horizontal extent 1-2 clock hours. Patient then underwent a GDD implant surgery on the right eye, IOP 8 mmHg post GDD. Three months after surgery, the visual acuity decrease into 6/120 ph 6/21, elevated IOP into 32 with prominent lens opacity, so the phacoemulsification was done to the right eye After the surgery, patient’s intraocular pressure was stable with better visual acuity. Conclusion: In trabeculectomy failure, implantation of the GDD is the safest and most effective option in eyes that have undergone previous intraocular surgery.
