This novel corneal trabeculectomy avoids conjunctival incisions and intracameral manipulation, effectively reducing intraocular pressure in glaucoma patients. The technique shows promise for safer, more accessible glaucoma filtration surgery.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Glaucoma management often involves filtration surgery to reduce intraocular pressure.
  • Traditional trabeculectomy requires conjunctival incision and intracameral manipulation, posing risks and requiring specialized skills.
  • There is a need for less invasive and more accessible glaucoma surgical techniques.

Purpose of the Study:

  • To describe and evaluate a novel corneal trabeculectomy technique.
  • To assess the safety and efficacy of this technique in reducing intraocular pressure.
  • To determine if the technique can be performed without conjunctival incision or intracameral manipulation.

Main Methods:

  • A partial-thickness limbal corneal flap was used to access an intrastromal limbal pocket.
  • The subconjunctival space was entered using an irrigating cystotome.

  • The anterior chamber was accessed at the limbus, and peripheral iridectomy was performed.
  • Guarded limbal fistulas were created in five glaucoma patients.

    • Main Results:

    • The technique was successfully completed in eye-bank eyes, cat eyes, and glaucoma patients.
    • Low-lying, diffuse filtration blebs were observed, persisting for three months.
    • Mean intraocular pressure was significantly reduced from 33 to 12 mm Hg.
    • The procedure was performed without conjunctival incision or intracameral manipulation.

    Conclusions:

    • Corneal trabeculectomy offers a promising alternative filtration surgery.
    • This technique avoids conjunctival incision and intracameral manipulation, potentially reducing surgical risks.
    • The method does not require costly technology, enhancing accessibility for glaucoma treatment.
