Selective Laser Trabeculoplasty (SLT) is a common alternative or adjunct to topical therapy for glaucoma. In SLT, laser energy is directed at the drainage structures of the eye where it is absorbed by melanin. This elicits a localized inflammatory response which in turn allows the natural drain to function more efficiently to lower the eye pressure.
If your doctor detects a component of anatomically narrow angles or angle closure, laser iridotomy may be indicated. In this procedure, laser energy is used to create an opening through the iris in order to open the angle and prevent or treat angle closure glaucoma.
