360° ab-interno Schlemm's canal viscodilation in primary open-angle glaucoma

To evaluate the safety and effectiveness of ab-interno microcatheterization and 360 viscodilation of Schlemm's canal (SC) using the VISCO360 Viscosurgical System in treatment of primary open angle glaucoma (POAG). Surgical center (Augencentrum Köln, Köln, Germany). Retrospective analysis of 106 eyes from 71 consecutive patients. Ab-interno canal viscodilation (VISCO360 ) 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 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. Ab-interno SC viscodilation (VISCO360) is safe and effective in lowering IOP and reducing hypotensive medications in patients with OAG.
