Early experience with the novel glaucoma shunt device: Paul glaucoma implant in the Indonesian populations

Abstract:

AIM: To investigate the safety and efficacy of Paul glaucoma implant(PGI)in the short-term follow-up period and share first experience with this novel aqueous shunt in Indonesian populations.

METHODS: A total of 21 patients(22 eyes)with PGI implants from April 2022 to December 2022 and with at least a complete 2mo follow-up were retrospectively analyzed. The primary outcome measure was failure, defined as intraocular pressure(IOP)out of the target range of 21 mmHg or less than 20% reduction from baseline for 2 consecutive visits, other glaucoma surgeries required, or removal of the implant.

RESULTS: The follow-up period was 2 to 6mo. The mean IOP reduction was 52.27±22.94%, with a range of 9% to 90%. The complete success rate was 59%, and patients with or without a history of glaucoma surgery had 50% and 59% of complete success rates, respectively. Complications of the surgery were diplopia(n=2), early hypotony(n=1), hyphema(n=1), and exposed tube(n=2).

CONCLUSION: The complete success of the PGI implantation was 57%. No serious postoperative complications were found in our cases. One case of hypotony resolved in the early postoperative period.
