Suture lysis after trabeculectomy is not innocuous, causing complications like flat chambers and leaks. However, appropriate management ensures no impact on final intraocular pressure outcomes.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery

Background:

  • Suture lysis is a common procedure post-trabeculectomy to enhance bleb function.
  • It is widely perceived as a low-risk intervention.

Purpose of the Study:

  • To evaluate the safety of suture lysis following trabeculectomy.
  • To compare complication rates and outcomes between eyes undergoing suture lysis and a control group.

Main Methods:

  • Analysis of 200 consecutive trabeculectomies performed between January 1992 and October 1993.
  • Comparison of 99 eyes with suture lysis versus 101 eyes without suture lysis.

Main Results:

  • Suture lysis was associated with complications including flat anterior chambers (13.1%), external aqueous leaks (9%), malignant glaucoma (2%), iris incarceration (2%), and large blebs (2%).

Related Experiment Videos

  • All noted complications were successfully managed.
  • No significant difference in mean postoperative intraocular pressure was observed between the suture lysis and control groups.

    • Conclusions:

    • Suture lysis following trabeculectomy carries risks and is not an innocuous procedure.
    • Despite potential complications, effective management leads to favorable intraocular pressure outcomes.
