Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Medical Devices

Background:

  • Complicated glaucoma often presents challenges in intraocular pressure (IOP) management.
  • Refractory glaucoma cases may require advanced surgical interventions beyond standard medical therapy.

Purpose of the Study:

  • To evaluate the efficacy of pneumatically stented drainage tube implants, specifically modified for pars plana insertion, in treating complicated glaucoma.
  • To assess the safety and effectiveness of the pneumatically stented implant (PSI) procedure for refractory glaucoma.

Main Methods:

  • A retrospective case series involving 50 patients with refractory complicated glaucoma.
  • Baerveldt glaucoma implants, modified with a Hofmann elbow for pars plana insertion, were utilized.
  • The procedure involved pars plana vitrectomy and gas-fluid exchange.

Main Results:

  • The study included 50 eyes with neovascular and non-neovascular glaucoma, with an average follow-up of 18 months.
  • Preoperative IOP averaged 44 mmHg, reduced to a mean of 14 mmHg postoperatively.
  • 94% of patients achieved a final IOP of 21 mmHg or less, with a significant reduction in glaucoma medications.

Conclusions:

  • Pneumatically stented Baerveldt glaucoma implants, modified for pars plana insertion, demonstrate significant efficacy in managing complicated glaucoma.
  • The PSI procedure offers a viable surgical solution for patients with refractory glaucoma, achieving substantial IOP reduction and medication decrease.
