Prolene suture gonioscopy-assisted transluminal trabeculotomy safe and effective treatment of glaucoma: Study
Researchers found that prolene suture gonioscopy-assisted transluminal trabeculotomy (GATT) is efficient in reducing intraocular pressure (IOP) and diminishing the long-term usage of glaucoma medication. A recent study was published in the Journal of Glaucoma conducted by Zhang and colleagues.
The objective of the study was to evaluate the long-term effectiveness of prolene suture GATT in reducing IOP, and in minimizing the use of glaucoma medications, while identifying the risk factors for surgical outcomes. This was a retrospective cohort study of adult patients undergoing prolene suture GATT by a single surgeon at a medical center. Data from 145 eyes of 124 patients were analyzed concerning changes in intraocular pressure, use of glaucoma medications, and rates of reoperation up to four years of follow-up.
The study showed a marked reduction of IOP from a preoperative level of 22.1±7.8 mm Hg to 15.1±3.2 mm Hg at three years and 15.1±3.5 mm Hg at four years after the surgery.
• The number of medications for glaucoma was also reduced. It came down to 1.3 ± 1.4 at three years and 1.4 ± 1.5 at four years post surgery from the baseline of 3.2 ± 1.1 preoperatively. What was impressive was that 44% of the eyes were totally medication-free at year four.
