Iridotomy with a ruby laser

Abstract

The use of a ruby laser mounted on a slit-lamp microscope for the out-patient treatment of closed-angle glaucoma, and some cases of secondary glaucoma, is described. Good results were obtained when marked thinning or a complete iridotomy was produced in the iris; this usually required repeated treatment at intervals of a week or more. No serious complications have been encountered and no damage to the lens or retina has been detected.
