Özet

Purpose: To evaluate the impact of varying degrees of trabeculotomy during gonioscopy-assisted transluminal trabeculotomy surgery on postoperative intraocular pressure reduction and surgical success. Methods: Patients who underwent gonioscopy-assisted transluminal trabeculotomy (at least 90 degrees) for open-angle glaucoma and had a follow-up period of at least 12 months were included. Patients were grouped according to trabeculotomy degree (Group 1: 90 degrees0.05). No correlation was found between trabeculotomy degree and percentage intraocular pressure reduction (p=0.173). At 12 months, surgical success rates were similar (60.0%, 58.3%, and 64.3% for Groups 1, 2, and 3, respectively). Complication rates were also comparable among the groups. Conclusion: The degree of trabeculotomy did not affect surgical success over a 12-month follow-up period. Although early intraocular pressure reduction may differ with 360 degrees trabeculotomy, a complete 360 degrees incision may not be necessary to achieve optimal pressure reduction.
