Suprachoroidal Drainage Devices - Six Months Experience

Abstract

Purpose: To evaluate the clinical outcomes of patients with suprachoroidal drainage devices.

Methods: The authors describe 4 cases of patients presenting with preoperative intraocular pressures (IOP) between 30-40 mmHg, under triple glaucoma medication and history of multiple intraocular surgeries, who underwent suprachoroidal drainage device (StarFlo®) implantation. The following parameters were evaluated: preoperative and postoperative IOP (1 day, 1 week and 1, 3 and 6 months), the use IOP-lowering medication and operative and post-operative complications. IOP reduction in over 30% or <21mmHg was considered relative or absolute success depending on whether this was achieved with or without use of further surgical intervention or medical IOP-lowering treatment, respectively.

Results: At 3 months, there was a reduction in IOP greater than 30% to 3 months post-operative (Baseline IOP: 34 ± 2 mmHg, 3 months IOP: 13 ± 3 mmHg). After this period, IOP-lowering medication was re-started in 2 patients in order to sustain the higher than 30% IOP-lowering reduction. One of the patients with relative success criteria was lost in follow at 3 months. In our last observation, IOP remains lower than preoperative IOP (6 months IOP 13 ± 4 mmHg). No there were no complications during the procedure. A patient presented with hyphema in the first postoperative day, which spontaneously resolved.

Conclusions: Suprachoroidal drainage devices seem to reduce IOP significantly, are technically feasible and have few postoperative complications.
