PG - 1235-1246 LID - 10.2147/OPTH.S203917 [doi] AB - Purpose: To evaluate the safety and effectiveness of ab-interno microcatheterization and 360 degrees viscodilation of Schlemm's canal (SC) using the VISCO360((R)) Viscosurgical System in treatment of primary open angle glaucoma (POAG). Setting: Surgical center (Augencentrum Koln, Koln, Germany). Design: Retrospective analysis of 106 eyes from 71 consecutive patients. Methods: Ab-interno canal viscodilation (VISCO360((R))) with or without cataract extraction was performed in two groups of patients with mild-moderate POAG: Group 1 had a baseline intraocular pressure (IOP) >/=18 mmHg (n=72 eyes) and Group 2 had a baseline IOP <18 mmHg (n=34 eyes). IOP without washout was measured and number of IOP-lowering medications were documented at all visits. Effectiveness was determined by reduction in IOP and reduction in the number of IOP-lowering medications at 12+/-3 months from baseline. Safety was determined by the rate of adverse events (AEs) and secondary surgical interventions (SSI). Results: In Group 1, all eyes available at 12+/-3 months (n=72), had a 41.0% reduction in mean IOP (from 24.6+/-7.1 mmHg to 14.6+/-2.8 mmHg), 87% (n=62) of which showed an IOP reduction of >/=20% with no increase in IOP-lowering medications. In Group 2, all eyes (n=34) maintained their baseline IOP at all postoperative visits. In both groups, a significant decrease (>89%) in mean number of IOP-lowering medications was seen at 12 months with 86% of eyes completely off medication with no increase in IOP. The most common AE seen was hyphema (13%) and no eye required SSI during the study period. Conclusion: Ab-interno SC viscodilation (VISCO360) is safe and effective in lowering IOP and reducing hypotensive medications in patients with OAG.
