© 2014, Springer Science+Business Media Dordrecht. To compare the complication rate and effectiveness of mitomycin C (MMC), Ologen alone, and Ologen with 5-fluorouracil (5-FU) as adjunctives with Ex-PRESS mini shunt for medically uncontrolled glaucoma. Retrospective comparative study of 59 Ex-PRESS mini shunt trabeculectomy operations coupled with Ologen implantation alone, transient MMC application or Ologen implantation with 5-FU as adjunctive treatment. Eight eyes (7 patients) received Ologen alone, 37 eyes (34 patients) received MMC, and 14 eyes (14 patients) received Ologen with 5-FU as adjunctive therapy. Baseline characteristics, adjunctive used during operation, along with outcomes including intraocular pressure (IOP), number of anti-hypertensive drops, visual acuity, and complications were documented and compared. The primary outcome was IOP at 12 months. Variables were compared with r × c Fisher tests. The Ologen only group had a significantly higher IOP at 12 months (20.5 ± 10.23 mmHg) compared with Ologen combined with 5-FU (12.2 ± 1.47 mmHg) or MMC (13.8 ± 4.37 mmHg) (p = 0.015, linear mixed model). The Ologen only cohort also had a higher re-operation rate (p = 0.01, Fisher’s Exact Test) and higher rate of bleb leak (p = 0.02, Fisher’s Exact Test). Visual acuity was similar among all three groups. 5-FU with Ologen is as effective as MMC in maintaining IOP following Ex-PRESS shunt surgery at 1 year. However, Ologen alone may not be as effective as the other two adjunctive agents.
