Improved nonpenetrating trabeculectomy with sinusotomy and trabeculotomy effectively lowers intraocular pressure in glaucoma patients. This combined surgical approach demonstrated superior results compared to nonpenetrating trabeculectomy with sinusotomy alone, with no significant complications.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Glaucoma Management

Background:

  • Glaucoma necessitates effective intraocular pressure (IOP) reduction to prevent optic nerve damage.
  • Nonpenetrating glaucoma surgeries aim to reduce IOP with fewer complications than traditional filtering procedures.
  • Trabeculotomy, a procedure to incise the trabecular meshwork, can enhance aqueous outflow.

Purpose of the Study:

  • To evaluate the surgical outcomes and complications of an improved nonpenetrating trabeculectomy combined with sinusotomy and trabeculotomy.
  • To compare the efficacy of this combined procedure against nonpenetrating trabeculectomy with sinusotomy alone in glaucoma patients.

Main Methods:

  • A retrospective comparison of 63 eyes from 51 glaucoma patients across two institutions.

  • Patients underwent either nonpenetrating trabeculectomy with sinusotomy alone or combined with trabeculotomy.
  • Outcomes assessed included final intraocular pressure, medication score, and postsurgical complications.

    • Main Results:

    • Both surgical groups achieved significant reductions in intraocular pressure and medication scores.
    • The combination of nonpenetrating trabeculectomy, sinusotomy, and trabeculotomy resulted in significantly lower final IOP (P = 0.016) and drug scores compared to nonpenetrating trabeculectomy with sinusotomy alone.
    • No significant postsurgical complications were reported in either group.

    Conclusions:

    • The combination of nonpenetrating trabeculectomy, sinusotomy, and trabeculotomy provides satisfactory IOP reduction in glaucoma management.
    • This enhanced surgical technique appears to be safe and effective, offering a potential advantage over nonpenetrating trabeculectomy with sinusotomy alone.
