Trabeculectomy with MMC (Mitomycin-C) / 5-Fluorouracil (5-FU) is a surgical procedure performed to treat glaucoma, a condition characterized by increased pressure within the eye that can lead to optic nerve damage and vision loss if left untreated. Here's a breakdown of each component:

1. Trabeculectomy: This is a surgical procedure aimed at lowering intraocular pressure (IOP) by creating a new drainage channel for the aqueous humor (fluid inside the eye) to leave the eye. During trabeculectomy:

• A small flap is created in the sclera (white part of the eye).
• A tiny piece of the trabecular meshwork (the drainage structure of the eye) may be removed or bypassed.
• This creates a new pathway for fluid to drain from the eye, reducing intraocular pressure.
• Mitomycin-C: A potent anti-cancer agent that is also used as an antimetabolite in ophthalmic surgery. It inhibits fibroblast proliferation and reduces scar formation around the bleb, increasing the success of maintaining lower IOP over time.
• 5-Fluorouracil (5-FU): Another antimetabolite drug that inhibits cell proliferation and can be used similarly to MMC to prevent scarring and improve surgical outcomes in trabeculectomy.

1. MMC (Mitomycin-C) / 5-Fluorouracil (5-FU): These are medications used adjunctively during trabeculectomy to improve the success rate of the surgery by preventing scarring and fibrosis around the newly created drainage channel (bleb). These medications:

Indications for Trabeculectomy with MMC / 5-Fluorouracil:

• Uncontrolled Glaucoma: When medications and other conservative treatments fail to adequately control intraocular pressure.
• Advanced Glaucoma: To prevent further damage to the optic nerve and preserve vision.
• Narrow or Closed Angle Glaucoma: In cases where the angle between the iris and cornea is narrow or closed, preventing normal fluid drainage.
  • Trabeculectomy with MMC or 5-FU is highly effective in lowering intraocular pressure, thereby reducing the risk of optic nerve damage and progression of glaucoma.
  • The use of MMC or 5-FU helps to inhibit scar formation around the surgical site (bleb), which improves the success rate of maintaining lower IOP over the long term.
  • Successful trabeculectomy may reduce or eliminate the need for glaucoma medications, improving patient compliance and reducing side effects associated with topical medications.
  • By lowering IOP and preventing further damage to the optic nerve, trabeculectomy can preserve or improve vision in patients with glaucoma.
  • Trabeculectomy with MMC or 5-FU can be performed for different types of glaucoma, including primary open-angle glaucoma, angle-closure glaucoma, and secondary glaucomas.

Advantages of Trabeculectomy with MMC / 5-Fluorouracil:

1. Effective Reduction of Intraocular Pressure (IOP):
2. Improved Surgical Success Rate:
3. Potential Reduction in Glaucoma Medications:
4. Preservation of Vision:
5. Suitability for Various Types of Glaucoma:

Disadvantages of Trabeculectomy with MMC / 5-Fluorouracil:

1. Risk of Complications:

• Hypotony: Over-reduction of IOP leading to low eye pressure, which can affect vision and require additional interventions.
• Infection: Risk of infection at the surgical site (bleb), although this risk is minimized with proper surgical technique and post-operative care.
• Cataract Formation: Accelerated development of cataracts due to changes in the eye's structure and fluid dynamics.
• Bleb-related Complications: Issues related to the functioning of the bleb, such as leaks, infections, or encapsulation, which may necessitate further treatment.
• Trabeculectomy with MMC or 5-FU requires meticulous post-operative care, including frequent monitoring of IOP, use of medications (such as antibiotics and corticosteroids), and compliance with follow-up appointments.
• Despite advancements and use of adjunctive medications, there is a risk of surgical failure where the desired reduction in IOP is not achieved or maintained over time.
• Some patients may require additional procedures or interventions to manage complications or achieve optimal IOP control post-trabeculectomy.

1. Post-operative Care Requirements:
2. Risk of Surgical Failure:
3. Potential Need for Additional Procedures:

Considerations:

• Individualized Treatment: The decision to undergo trabeculectomy with MMC or 5-FU should be based on the specific characteristics of the patient's glaucoma, overall health, and other factors discussed with their ophthalmologist.
• Alternative Treatments: Depending on the type and severity of glaucoma, alternative treatments such as minimally invasive glaucoma surgeries (MIGS), laser trabeculoplasty, or medical management may be considered before or alongside trabeculectomy.
• Patient Education and Consent: Patients should have a thorough understanding of the potential benefits, risks, and requirements associated with trabeculectomy with MMC or 5-FU before providing informed consent for the procedure.
  • Trabeculectomy: Creation of a new drainage channel (bleb) to improve aqueous humor outflow and reduce IOP.
  • MMC / 5-FU: Adjunctive use of MMC or 5-FU to inhibit scar formation around the bleb, thereby improving the success rate of maintaining lower IOP.
  • Effective Reduction of Intraocular Pressure: Trabeculectomy with MMC or 5-FU can significantly lower IOP, potentially reducing the need for glaucoma medications.
  • Improved Long-term Management: Helps in controlling glaucoma progression and preserving visual function.
  • Customizable Approach: Surgeons can tailor the procedure based on the specific needs and condition of the patient.
  • Hypotony: Risk of excessively low IOP, which can affect vision and may require further intervention.
  • Infection: Potential for infection at the surgical site (bleb), although precautions are taken to minimize this risk.
  • Cataract Formation: Accelerated development of cataracts due to changes in the eye's structure and fluid dynamics.
  • Bleb-related Issues: Complications related to the functioning of the bleb, such as leaks, infections, or encapsulation.
  • Surgical Risks: Possible risks include bleeding, inflammation, or damage to other eye structures, though these are uncommon with experienced surgeons.
