What is a Laser Peripheral Iridotomy?

Patients having narrow angles inside their eye, can develop raised intraocular pressure and even acute angle closure glaucoma leading to a complete loss of vision. In order to prevent this occurring a laser beam can be used to create small holes in the iris which allow trapped fluid behind the iris an alternative route for drainage and opening of the angles preventing angle closure glaucoma. This provides an alternative pathway for fluid to move freely into the trabecular meshwork (the main drainage mechanism of the eye.) You may be given eye pressure lowering medications and anti-inflammatory drops after having laser peripheral iridotomies performed.
