Streamline system helps reduce IOP, medications in open-angle glaucoma

WASHINGTON — Patients with glaucoma who underwent goniotomy and viscodilation with the Streamline surgical system experienced reductions in IOP and medications, according to a study.
“It is not an invasive procedure,” Elizabeth Yeu, MD, said at the American Society of Cataract and Refractive Surgery meeting. “It rests and allows for suction and retraction of the outer sleeve and a gentle goniotomy performed by this inner cannula.”
The study included 21 patients with a diagnosis of mild to moderate open-angle glaucoma who were on one to three IOP-lowering medications and had a washed-out IOP between 21 mm Hg and 36 mm Hg. Data were collected at day 1, week 1, and months 1, 3, 9 and 12 following the procedure with the Streamline surgical system (New World Medical).
The primary endpoint was the proportion of unmedicated eyes with an IOP reduction of at least 20% from baseline at month 12. Intraoperative and postoperative adverse events, change in mean unmedicated IOP from baseline to month 12, and the number of topical glaucoma medications used at screening compared with month 12 were also assessed.
Yeu said 95.2% of patients experienced at least 20% reduction in IOP and no increase in medication use. The average IOP decreased from 23.9 mm Hg at baseline to 14.9 mm Hg at month 9 (P < .001). The average number of medications decreased from 2.1 at screening to 1.1 (P = .003).
Yeu said there were no adverse events related to the procedure.
