Abstract #15460 Published in IGR 1-3
The role of peripheral iridotomy in the management of primary angle closure glaucoma and the angle at risk
Dunphy RWPractical Optometry 1999; 10: 204-209
Primary angle closure glaucoma (PACG) is a condition wherein the peripheral iris is displaced and pushed against the trabecular meshwork by a relative pressure increase in the posterior chamber. The relative pressure increase that displaces the iris is a consequence of a blockade of aqueous movement from the posterior chamber to the anterior chamber. The risk factors that precipitate this blockade are both anatomical and physiological. The clinician can evaluate a patient's angle and determine whether or not it is in angle closure or is at significant risk for closure by careful assessment of the angle structure and configuration. The primary pupil block that precipitates the closure can be relieved by peripheral iridotomy in management of acute angle closure and as prophylaxis against possible angle closure in angles at significant risk.
