Cochrane Review: Iridotomy to slow progression of visual field loss in angle-closure glaucoma

Zusammenfassung

# Iridotomy to slow progression of visual field loss in angle-closure glaucoma. ## BACKGROUND Primary angle-closure glaucoma is a type of glaucoma associated with a physically obstructed anterior chamber angle. For example, contact between the iris and lens at the pupillary margin creates a pupillary block that increases resistance to aqueous outflow. Obstruction of the anterior chamber angle blocks drainage of fluids (aqueous humor) within the eye and may raise intraocular pressure (IOP). Ele

using laser.

However, the effective...

The date of the most recent search was 10 October 2021. ## SELECTION CRITERIA Randomized or quasi-randomized controlled trials that compared iridotomy with no iridotomy in primary angle-closure suspects, people with primary angle-closure, or people with primary angle-closure glaucoma in one or bo...

ipant to iridotomy and the other to no iridotomy. Two studies provided long-term (five or more years) results. We judged the certainty of the evidence as moderate to low across the prespecified outcomes, downgrading for high risk of bias (e.g. performance and detection biases) and imprecision of res...
