Abstract
Introduction & Objectives
Glaucoma drainage device (GDD) implantation was an effective surgical procedure in treating
uncontrolled intraocular pressure (IOP) of glaucoma patients in certain complicated conditions. GDD
implants were classified into valved and non-valved in which its surgical outcomes in different types
of device and various etiologies were not similar. This study aimed to evaluate the surgery outcomes
of GDD implantation in patients with refractory glaucoma at Sardjito General Hospital.
Methods
All 12 eyes of 11 patient’s medical records who underwent GDD implantation during 2022 at Sardjito
General Hospital was reviewed. Baseline data include age, gender, eye laterality, type of glaucoma,
IOP and visual acuity. The IOP and visual acuity (LogMAR) were measured at week 1, month 1, 2
and 3. Type of GDD implants, postoperative glaucoma medications, complications and need for
further glaucoma surgery were documented.
Results
The mean IOP at baseline was 44 ± 14.2 mmHg with 3.4 ± 0.6 glaucoma medications. It decreased
after surgery into 19.1 ± 11.2 mmHg (p=0.003) at 3 months follow up with 0.7 ± 1.7 (p=0.002)
glaucoma medications. The mean initial visual acuity was 1.9 ± 0.6 and changed insignificantly to
1.7 ± 0.8 (p=0.624) at last follow up. Six eyes (50%) were implanted with valved implant. The most
common early postoperative complications were recurrent high IOP (4 eyes, 33.3%) associated to
ripcord of non-valved implant (p=0.025). Five eyes (41.7%) needed additional surgery related to
non-valved implant type (p=0.003).
Conclusion
GDD implantation especially valved type appears to be safe and effective surgical option in treating
refractory glaucoma patients.
