Causes of Narrow-Angle Glaucoma Causes of the abnormal positioning of the iris in narrow-angle glaucoma include: Pupillary block. [allaboutvision.com]

Angle crowding — this may occur due to an abnormally configured iris, e.g. plateau iris, that obstructs the angle during pupillary dilatation. [lifeinthefastlane.com]

Pupillary block occurs when aqueous humor cannot pass from the posterior to the anterior chamber because of iridolenticular apposition. [journal.opted.org]
