Trabeculectomy effectively controlled intraocular pressure in 67% of chronic open-angle glaucoma patients long-term. However, other glaucoma types and cataract development often require additional treatments and monitoring.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery

Background:

  • Trabeculectomy is a common surgical procedure for glaucoma.
  • Long-term outcomes of trabeculectomy require further investigation.

Purpose of the Study:

  • To evaluate the long-term intraocular pressure control after trabeculectomy.
  • To assess the incidence of subsequent interventions and complications.

Main Methods:

  • Retrospective study of 81 eyes undergoing trabeculectomy.
  • Mean follow-up period of 9.2 years (range 7-10 years).
  • Analysis of intraocular pressure patterns, need for medications, cataract extraction, and visual field changes.

Main Results:

  • 67% of chronic open-angle glaucoma eyes maintained pressures below 21 mmHg with trabeculectomy alone.

  • 65% of other glaucoma types required additional medications.
  • 22% of phakic eyes needed cataract extraction; 5% experienced blinding complications.
  • Visual field outcomes varied, with 17% gaining and 50% losing field over time.

    • Conclusions:

    • Trabeculectomy provides sustained intraocular pressure control for a majority of chronic open-angle glaucoma patients.
    • Long-term management may involve additional medications or cataract surgery, with a risk of complications and visual field changes.
