goniotomy
Pronunciation: goh-nee-OT-oh-mee
A minimally invasive glaucoma surgery that opens the trabecular meshwork using a microcatheter or probe.
Full Definition
Goniotomy is a surgical procedure designed to restore normal aqueous outflow in glaucoma patients by opening the trabecular meshwork. Modern techniques include ab interno goniotomy performed with specialized devices like the Kahook Dual Blade or goniotomy probes. The procedure is performed through a clear corneal incision using gonioscopic visualization, making it less invasive than traditional filtration surgeries. Success depends on proper patient selection and adequate post-operative follow-up to monitor intraocular pressure control.
Usage
Usage note: Distinguish from gonioscopy (diagnostic procedure) and specify ab interno vs. traditional approach.
