Objective: To evaluate and compare the structural and functional outcomes of conventional and sutureless methods of trabeculectomy at 6-month follow-up.

Methods: Of the patients referred for trabeculectomy, 18 were selected (8 males and 10 females). Patients were randomly divided into two equal groups: conventional surgery and sutureless surgery. Bleb morphologic parameters were measured using anterior segment optical coherence tomography at 6 months follow-up. The obtained data were statistically analyzed by T-test and Chi-square using SPSS software.

Results: The mean postoperative morphological parameters including bleb height, width, and wall thickness were lower in the sutureless group while the difference was not statistically significant. Bleb wall pattern, reflectivity, and vascularity difference between the two groups were also not statistically significant. Furthermore, there was no statistically significant difference in intraocular pressure between the two groups.

Conclusion: No significant difference in bleb morphology parameters and intraocular pressure was observed between the two groups of conventional and sutureless methods at 6 months follow-up. A study with a longer follow-up and a higher statistical population is recommended.
