Purpose: Evaluate factors contributing to ptosis after glaucoma surgery.
Methods: Three-year retrospective chart review from January 1, 2012, to January 1, 2015, 157 eyes, 3 surgeons, at Boston Medical Center, to determine the incidence of ptosis and the effects of each variable contributing to ptosis at 3 months after surgery. Each variable was analyzed using the chi-square or independent samples t-test analysis to determine statistical significance of ptosis compared with above variables.
Results: The t-test or chi-square analysis showed that gender, steroid duration, use of mitomycin C, duration of surgery, and prior surgeries were not statistically significant factors for ptosis. There was a statistically significant association between those <70 years of age and ptosis (P<0.05), non-combined surgery and ptosis (P<0.05), shunting surgery and ptosis (P<0.05).
Conclusion: Ptotic changes occurred more often in those who have shunting (Ahmed and Baerveldt) surgeries compared with filtering (trabeculectomy and Express) surgeries.
Keywords: ptosis, trabeculectomy, shunting surgery, filtering surgery, glaucoma, combined surgery
