All patients had proliferative diabetic retinopathy before undergoing elective pars plana vitrectomy and oral treatment with placebo or levosulpiride. P values compare basal values of groups receiving placebo and levosulpiride. BMI, body mass index; CI, confidence interval; DM2, type 2 diabetes mellitus; HbA1c, glycosylated hemoglobin; SCr, serum creatinine; eGFR, estimated glomerular filtration rate (CKD-EPI equation); SPRL, serum PRL.
