Long-term outcome of surgical management in neovascular glaucoma: A retrospective, multicentric study.

Abstract

Purpose: This study aimed to evaluate and compare surgical outcomes among neovascular glaucoma patients undergoing trabeculectomy (Trab), glaucoma drainage device (GDD) implantation, or trans-scleral cyclophotocoagulation (TSCPC).

Methods: This study analyzed the records of 176 neovascular glaucoma cases treated surgically between January 2017 and December 2021 at four Indian centers. Procedures included trabeculectomy with MMC in 80 eyes, GDD implantation in 25 eyes, and TSCPC in 71 eyes. Outcome measures comprised intraocular pressure (IOP) reduction, antiglaucoma medication (AGM) usage, complications, and best-corrected visual acuity (BCVA).

Results: Following surgery, all groups exhibited a significant reduction in IOP. One year postoperatively, complete success rates were 42.9% for the implant group, 54.3% for the Trab group, and 33.3% for the TSCPC group, with corresponding qualified success rates of 57.1%, 36.7%, and 58.9%, respectively. Improvement in postoperative vision was noted, with an increase of 0.24 LogMAR in the Trab group, 0.11 in the GDD group, and a decrease of 0.35 in the TSCPC group. Complications occurred in 27% of Trab and 14% of TSCPC cases, while the GDD group experienced a hypertensive phase in 40% of eyes.

Conclusion: In managing neovascular glaucoma, trabeculectomy, GDD, and TSCPC provide comparable IOP control, with GDD showing a higher medication dependency. Trabeculectomy yields superior vision outcomes but carries a higher risk of postoperative complications, emphasizing the importance of individualized treatment selection and vigilant postoperative care.
