Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Tissue Microscopy

Background:

  • Trabeculectomy is a common surgical procedure for glaucoma.
  • Mitomycin C is an antimetabolite used to enhance surgical outcomes.
  • Its specific effects on scleral tissue in the Turkish population require investigation.

Purpose of the Study:

  • To evaluate the efficacy and safety of mitomycin C-aided trabeculectomy.
  • To investigate the ultrastructural changes in scleral tissue post-mitomycin C application.
  • To assess the pressure-lowering effect in a Turkish patient cohort.

Main Methods:

  • Prospective, randomized clinical trial comparing mitomycin C-aided trabeculectomy with standard trabeculectomy.
  • Inclusion of diverse glaucoma types and prior failed surgeries.

  • Light and transmission electron microscopy of excised scleral tissues.

    • Main Results:

    • Mitomycin C group showed significantly greater intraocular pressure (IOP) reduction (P < 0.01).
    • Fewer additional medications were required post-operatively in the mitomycin C group (P < 0.01).
    • Electron microscopy revealed frayed collagen fibrils, loss of proteoglycan cross-links, and fibroblast damage in mitomycin C-treated tissues.

    Conclusions:

    • Mitomycin C is safe and effective as an adjunct to trabeculectomy for various glaucoma types.
    • The drug impacts scleral tissue by disrupting collagen organization and affecting fibroblasts.
    • These findings support the use of mitomycin C to improve surgical outcomes in glaucoma management.
