Trabeculectomy for glaucoma shows decreasing success over time, with 42% of patients remaining stable after 10 years. Capsular glaucoma had better outcomes than simple glaucoma, and cataract was a frequent complication.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Outcomes

Background:

  • Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
  • Trabeculectomy remains a common surgical intervention for managing advanced glaucoma.
  • Long-term outcomes of trabeculectomy, particularly differentiating glaucoma types, require further elucidation.

Purpose of the Study:

  • To evaluate the long-term efficacy and progression of glaucoma after trabeculectomy.
  • To compare the outcomes between capsular glaucoma and simple glaucoma following surgery.
  • To identify factors influencing prognosis and complications after trabeculectomy.

Main Methods:

  • A retrospective study of 277 primary open-angle glaucomas in 239 patients.
  • Follow-up duration of up to 10 years post-trabeculectomy.

  • Assessment of glaucoma progression, need for medical therapy, and visual acuity changes.

    • Main Results:

    • Glaucoma stability without additional therapy decreased over time: 75% at 1 year, 70% at 2 years, 57% at 5 years, and 42% at 10 years.
    • Capsular glaucoma demonstrated significantly slower progression compared to simple glaucoma.
    • Preoperative high intraocular pressure and advanced glaucoma damage did not predict poorer outcomes; cataract developed in 37% of eyes within 5 years.

    Conclusions:

    • Trabeculectomy offers diminishing long-term control for primary open-angle glaucoma, with capsular types showing better sustained results.
    • Surgical outcomes are influenced by glaucoma subtype, with cataract being a significant post-operative complication impacting visual acuity.
    • Further research is needed to optimize surgical strategies and manage long-term complications effectively.
