Heersink M, et al. - In patients with primary open-angle glaucoma (POAG), researchers assessed outcomes of trabecular meshwork (TM) bypass (iStent GTS100) with cataract extraction (CE) and TM-bypass + ab interno canaloplasty (CP) (VISCO360) with CE. The study sample consisted of 186 eyes from 130 consecutive patients with 6 months follow-up. In this retrospective analysis, eligible eyes had POAG, indicated for CE, and had received CE + TM-bypass or CE + TM-bypass + CP. At six months, a higher percentage of patients with CE + TM-bypass + CP accomplished an IOP decrease of ≥ 20% and an IOP < 18 mmHg on the same or less drugs than for TM-bypass + CE.
