To identify the factors associated with the surgical outcomes of Baerveldt glaucoma implant (BGI) for open-angle glaucoma (OAG), the medical records of 51 consecutive OAG patients (age, 43-91 years) who underwent BGI were retrospectively reviewed (median follow-up, 21.7 months). Surgical success was defined as the following postoperative intraocular pressures (IOPs, mmHg): (A) 6 ≤ IOP ≤ 21; (B) 6 ≤ IOP ≤ 18; and (C) 6 ≤ IOP ≤ 15 without loss of light perception or additional glaucoma surgery. Univariate analysis showed that age (all criteria), glaucoma type (criterion C), and preoperative IOP (criteria A and B) were the candidate factors (P < 0.20). When the patients were divided into two groups according to median age (72 years), the success probability was higher in the older group for criteria B (P = 0.047) and C (P = 0.02), and the postoperative IOP was lower in the older group 1-year post-surgery (P = 0.002). Furthermore, the multivariate Cox proportional hazards model revealed that older age was independently associated with surgical success for criteria B (relative risk [RR], 0.94; P = 0.02) and C (RR, 0.94; P = 0.01). In conclusion, older age is a factor associated with the surgical success of BGI for OAG.
