LASER PERIPHERAL IRIDOTOMY (LPI)
Narrow angles refers to a crowding or shallowing of the anterior chamber - essentially the drain - in the front of the eye. When the angle is narrow, there is a risk that the eye pressure may go up and cause glaucoma. Because of this, it is a risk factor for glaucoma, but many people with narrow angles never develop glaucoma.
The pressure may rise slowly leading to chronic angle closure glaucoma, or suddenly, referred to as an acute glaucoma attack.
In order to prevent this pressure elevation, an in-office laser treatment is recommended - LASER PERIPHERAL IRIDOTOMY. The goal of this laser is to create more space in the front of the eye which dramatically reduces the risk of glaucoma. The laser takes about 5 minutes to do. Drops are instilled in the eye to prepare the eye prior to the procedure and a steroid drop is required for 1 week after the laser. There are no restrictions before or after the procedure.
