Postoperative Outcomes After Implantation of Glaucoma Drainage Device in Indian Eyes
Narrative Responses:
Purpose
To evaluate outcomes following Ex-PRESS Glaucoma drainage device implantation in Indian eyes at 1-year follow-up
Methods
Prospective, observational case series included 40 eyes undergoing ExPRESS Glaucoma Drainage Device(Alcon Laboratories, USA) implantation for medically uncontrolled Primary Open Angle Glaucoma. Single Surgeon performed surgeries using standardized technique. Outcome measures included Intraocular Pressure(IOP), postoperative complications and medication use at 1 week,1,3,6,12 months. Surgical success classified as: Unqualified Success-IOP ≤18mmHg without antiglaucoma medications, Qualified Success-same as unqualified success,but with antiglaucoma medications, Treatment failure-need for additional antiglaucoma surgery
Results
Mean follow-up was 26+1.2 months. Mean IOP dropped from 20.3+5.1 mmHg preoperatively to 15.4+4.7, 13.3+3.5, 13.0+3.5 and 12.8+4.1 at 1,3,6,12 months. Unqualified success was achieved in 20 eyes(90 %) at 6 months and 17 eyes(77%) at 1 year. Qualified Success achieved in 98% eyes at 1 year. Mean number of medications reduced from 2.47 preoperatively to 1.11 at 1 year. Complications: Early postoperative shallow AC in 3 eyes(7.5%), early postoperative hypotony in 2 eyes(5%), localized iris chaffing in 3 eyes(7.5%) eyes. 3 eyes with pre-existing cataract required cataract surgery within 3 months of ExPRESS GDD implantation
Conclusion
At 1 year, ExPRESS GDD device provides good postoperative IOP control with acceptable postoperative complications
