PURPOSE: To report the incidence and outcomes of hypertensive phase (HP) following Aurolab Aqueous Drainage Implant (AADI) (Aurolab) surgery in adults with refractory glaucoma. DESIGN: Retrospective, noncomparative, interventional case series. METHODS: All eyes that received the AADI and had a minimum of 2-year follow-up were identified, and data of patients who had intraocular pressure (IOP) ≤21 mm Hg at 6 weeks (ie, the time at which the tube-ligature suture dissolves) were used for statistical analysis. HP was defined as IOP >21 mm Hg during the first 3 months after the release of the tube ligating suture (with or without medications) in the absence of tube obstruction. RESULTS: A total of 200 eyes were included in the study, and HP was seen in 64 eyes (32%) with a peak IOP (mean ± SD) of 29.6 ± 7.8 mm Hg and peak incidence at 2-3 months after surgery. HP resolved within 3 months of its onset in 60 of the 64 eyes (94%) with additional IOP-lowering medications. The cumulative success rates were 71.8% (95% CI = 59.3%-81.2%) in HP eyes and 76.4% (95% CI = 68.7%-82.7%) in non-HP eyes (P = .23). Unadjusted Cox proportional hazards analysis showed that eyes experiencing HP had a marginally higher risk of failure (HR = 1.16, 95% CI = 0.6-2.1), but this relationship was not statistically significant (P = .61). CONCLUSIONS: A third of eyes that underwent AADI placement experienced HP. HP was successfully managed with additional IOP-lowering medications in a majority of cases and did not have a significant influence on long-term success rate.
