  1. Data are presented in coefficient (95% confidence interval). In the multivariate linear regression model, data is adjusted by age and postoperative anti-glaucoma medications number. A p < 0.05 are considered as significant. EM: epithelial microcysts area, HD: density of hyperreflective dots, CT: connective tissue grade, POST-2 W: postoperative 2 weeks, POST-1 M: postoperative 1 month, POST-3 M: postoperative 3 months, POST-6 M: postoperative 6 months, POST-12 M: postoperative 12 months, POST-18 M: postoperative 18 months, POST-24 M: postoperative 24 months
