AI Article Synopsis
- Fistulising trabeculotomy has been a surgical method for about 20 years, merging minimally invasive procedures with the creation of a subconjunctival fistula.
- The procedure involved unroofing the canal of Schlemm and using a probe to manipulate it for effective pressure relief.
- In a study of 99 eyes, the surgery significantly lowered intraocular pressure (from an average of 29 mmHg to 14 mmHg) while demonstrating a low complication rate over a follow-up period of at least 10 years.
Article Abstract
Background: Fistulising trabeculotomy has been used for nearly 20 years to combine the minimally invasive surgery of trabeculotomy with production of a subconjunctival fistula.
Methods: The canal of Schlemm was unroofed 2mm on one side of a 3mm half-thickness scleral flap. A trabeculotomy probe was passed about 30 degrees along the canal on the opposite side and rotated into the anterior chamber.
Results: Of 99 eyes of 74 patients, 35 eyes of 25 patients were available for follow-up at 10 or more years. The mean IOP was 14 +/- 4 mmHg (range 7 to 23 mmHg) from a preoperative IOP of 29 +/- 8 mmHg (17 to 60 mmHg). Results in 44 similar patients undergoing trabeculectomy and 44 undergoing fistulising trabeculotomy were very similar at five-year follow-up.
Conclusion: Fistulising trabeculotomy was effective for lowering intraocular pressure with a low complication rate and a large area of subconjunctival fistulisation.
