Viscoelastic-augmented trabeculectomy (VAT) significantly lowers intraocular pressure (IOP) more effectively than conventional trabeculectomy (CT) in advanced glaucoma patients. VAT achieved target IOP in 60% of cases with fewer complications.

Area of Science:

  • Ophthalmology
  • Glaucoma Research

Background:

  • Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
  • Effective intraocular pressure (IOP) reduction is crucial for managing glaucoma progression.

Purpose of the Study:

  • To compare the efficacy and safety of viscoelastic-augmented trabeculectomy (VAT) versus conventional trabeculectomy (CT).
  • To evaluate IOP reduction and complication rates in POAG patients undergoing VAT or CT.

Main Methods:

  • A comparative study involving 65 POAG cases in each group (CT and VAT).
  • VAT procedure details included lamellar scleral flap, deep scleral flap, penetrating trabeculectomy, peripheral iridectomy, and viscoelastic/BSS use.
  • Success defined as IOP <14 mmHg without severe complications; statistical significance set at P < 0.05.

Main Results:

  • VAT demonstrated significantly lower mean IOP compared to CT at 6 weeks, 12 weeks, and 6 months postoperatively.
  • Target IOP was achieved in 60% of VAT cases versus 36.92% of CT cases.
  • VAT showed a trend towards lower postoperative complications.

Conclusions:

  • Viscoelastic-augmented trabeculectomy is an effective surgical option for achieving target IOP in advanced glaucoma.
  • VAT offers a promising alternative to conventional trabeculectomy with potentially improved outcomes and reduced complications.
