Summary
This study shows that an automated trephine (trabecuphine) can safely create a glaucoma fistula. Five of seven patients achieved controlled intraocular pressure (IOP) and a functional bleb after surgery.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Glaucoma filtering surgery can fail in aphakic patients or those with prior unsuccessful procedures.
- Minimizing conjunctival trauma is crucial for successful glaucoma surgery outcomes.
Purpose of the Study:
- To evaluate the safety and efficacy of an automated trephine (trabecuphine) for internal sclerectomy in glaucoma patients.
- To assess the creation of a patent fistula and postoperative intraocular pressure (IOP) control.
Main Methods:
- An automated trephine (trabecuphine) was used for internal sclerectomy in seven glaucoma patients.
- Postoperative subconjunctival injections of 5-fluorouracil (5-FU) were administered to six patients.
- Follow-up ranged from 4 to 24 months.
Main Results:
- A patent fistula was achieved intraoperatively in all seven eyes.
- Five of seven patients maintained a functional bleb and controlled IOP.
- The procedure demonstrated minimal conjunctival trauma and simplified adjunctive antimetabolite use.
Conclusions:
- The trabecuphine facilitates safe, internal glaucoma filtering surgery with reduced conjunctival trauma.
- This technique shows promise for managing complex glaucoma cases, including those with prior surgical failure.
