Abstract

Aim To determine the outcomes of Aurolab aqueous drainage implant (AADI) placed in the superotemporal versus the inferonasal quadrant in adult eyes with refractory glaucoma. Methods This was a retrospective study of eyes that had AADI placement and completed a minimum of 2-year follow-up. The choice of the quadrant was at the surgeon's discretion and mainly depended on the amount of scarring and conjunctival mobility. The cumulative failure rate of the AADI was defined as intraocular pressure (IOP) >21 mm Hg or not reduced by 20% below baseline on two consecutive follow-up visits after 3 months, IOP ≤5 mm Hg on two consecutive follow-up visits after 3 months, reoperation for glaucoma or a complication, or loss of light perception vision. Results We included 84 eyes with AADI in the inferonasal quadrant versus 69 eyes in the superotemporal quadrant. A significant drop in IOP was seen in both groups (18.4±10.4 mm Hg in the inferonasal group vs 17.7±11.1 mm Hg in the superotemporal group; p=0.63) at 3-month follow-up and this was maintained until last follow-up. Best-corrected visual acuity, IOP, number of IOP-lowering medications and complications were similar between the two groups at all time points. The cumulative success rate at 2-year follow-up without IOP-lowering medications was 57.1% (47.1%-68.1%) in the inferonasal group and 50.7% (39.8%-63.1%) in the superotemporal group (p=0.47). Conclusions Inferonasal AADI placement appears to be an equally safe and effective surgical option compared with superotemporal AADI placement and may be helpful in certain clinical situations.
