位于明尼阿波利斯的明尼苏达大学眼科顾问Thomas W. Samuelson博士在报告中指出：在一项国际性试验中，一名施行微支架手术的原发性开角型青光眼患者其眼内压(IOP)明显且持续性下降，我们对其进行长达12个月的随访后发现，微支架微创青光眼手术[MIGS]可安全有效地降低患者的眼内压。

　　One-Year Results of an Intracanalicular Microstent for IOP Reduction in Primary Open-Angle Glaucoma

　　Purpose: To evaluate the ability of a nickel titanium microstent implanted ab interno in the Schlemm canal to lower IOP in open-angle glaucoma patients.

　　Methods: Subjects diagnosed with mild to moderate open-angle glaucoma with visual field mean deviation ≥-12dB were recruited from 6 centers in a prospective, international case series. Subjects were washed out of glaucoma medications prior to surgery and at 1 year follow up.

　　Results: In 40 treated subjects, mean (±SD) IOP was reduced from 23.8 ± 3.5 at baseline to 18.0 ± 4.6 at 1 year (P< .05). Conclusion: An intracanalicular microstent may offer a durable alternative to medical therapy for IOP reduction.
