ABSTRACT
BACKGROUND: The purpose of this project was to determine whether conjunctiva-shortening posterior approach ptosis repair affects the complication rates of subsequent bleb-forming glaucoma filtering surgeries compared to conjunctiva-sparing anterior approaches.
METHODS: A retrospective cohort study was conducted at the Cleveland Clinic Cole Eye Institute, including patients who underwent ptosis repair followed by glaucoma filtering surgery between January 2010 and December 2024. Patients were divided into anterior approach (levator advancement) and posterior approach (Müllerectomy with or without tarsectomy) groups. Outcomes included rates of intraoperative complications and postoperative bleb-related complications. Fisher’s exact test was used for group comparisons, with p ≤ 0.05 considered significant.
RESULTS: Thirty-five eyes (34 patients) were included: 17 underwent anterior and 18 underwent posterior approach ptosis repair. Intraoperative complications occurred in one eye in each group. Postoperative bleb-related complications were reported in two eyes in the anterior group and one in the posterior group. Rates of bleb-related complications were not statistically different between groups. Anterior approach eyes were more likely to have had prior glaucoma surgery and require repeat ptosis repair.
CONCLUSION: Prior posterior approach ptosis repair does not significantly increase the risk of intraoperative or postoperative bleb-related complications in subsequent glaucoma filtering surgery. These findings support the safety of posterior approach ptosis repair, even in patients likely to require future filtering procedures.
