Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Ophthalmic Surgery

Background:

  • Bleb-related complications, including leaking blebs, overfiltration, and blebitis, can occur after glaucoma surgery.
  • Effective surgical management is crucial for addressing these complications and ensuring favorable outcomes.

Purpose of the Study:

  • To report the surgical management and outcomes of bleb-related complications.
  • To evaluate the efficacy of various surgical techniques in managing these complications.

Main Methods:

  • A retrospective analysis of 35 patients who underwent surgical repair of filtering blebs between 1991 and 2000.
  • Surgical techniques included autologous blood injection, fibrin glue, conjunctival suturing, flap resuturing, bleb excision, and patching.

Main Results:

  • Postoperative intraocular pressure (IOP) was regulated between 8 and 21 mmHg in 77.1% of cases without glaucoma medication.
  • For leaking blebs, mean IOP remained stable post-surgery (11.9+/-3.3 mmHg).
  • For overfiltration, mean IOP increased significantly post-surgery (13.5+/-3.7 mmHg), and mean visual acuity improved by 3.6+/-5.9 lines.

Conclusions:

  • Surgical bleb revision demonstrates a high success rate in maintaining a functioning filtering bleb.
  • This surgical approach is effective in preserving visual function after glaucoma surgery.
