: PRéCIS: Retrospective analysis of 38 suprachoroidal glaucoma stent implantations showed sudden intraocular pressure (IOP) elevations to >30 mm Hg in 37% of eyes, 39% needing additional glaucoma surgery, and a success rate at 12 months of 24%. PURPOSE: To study the efficacy and safety of suprachoroidal stent in everyday clinical practice at a tertiary glaucoma center. MATERIALS AND METHODS: This retrospective single-center consecutive case series involved patients treated at Helsinki University Hospital with the CyPass Micro-Stent. Preoperative IOP was ≥18 mm Hg. Success was IOP between 6 and 18 mm Hg and lowering of IOP at least 20% from baseline without an increase in glaucoma medications over baseline or use of oral acetazolamide, and no subsequent glaucoma surgery. RESULTS: Of the total 38 eyes of 33 patients, 17 had primary open-angle glaucoma, 16 had exfoliative glaucoma, 2 each had uveitic glaucoma or steroid-induced glaucoma, and 1 had pigmentary glaucoma. Median preoperative IOP was 25.8 [interquartile range (IQR), 9.7] mm Hg with a median of 3 (IQR, 2) glaucoma medications. Kaplan-Meier estimate of median survival time was 79 days (95% confidence interval, 37-121 d). Success rate at 12-month follow-up was 24%. Sudden IOP elevation to over 30 mm Hg occurred in 14 eyes (37%). Highest IOP was 68 mm Hg. IOP peaks occurred between 1 week and 8 months after the surgery. In total, 43% of those with IOP elevation to >30 mm Hg had no symptoms. After the CyPass implantation, 15 eyes (39%) needed additional glaucoma surgery within a median of 167 (IQR, 109) days. CONCLUSIONS: Suprachoroidal stenting in a heterogenous clinical population resulted in a high incidence of sudden IOP peaks with a low success rate.
