What is ALT glaucoma laser surgery?
ALT stands for Argon Laser Trabeculoplasty. ALT is a well-tolerated treatment for glaucoma that provides more stable pressure control than eye drops, without the risk of medication reactions inherent in eye drop use. ALT has been in use for 30 years, and studies have shown that, even at equal levels of average pressure control, when compared to patients on drops, those who had ALT suffered less loss of visual field over multi-year follow-ups (this study was called the Glaucoma Laser Trial, or GLT).
