It is well studied and documented that lowering eye pressure can slow down or prevent optic nerve damage or glaucoma. Currently to lower pressure  we use eye drops, laser procedures, and glaucoma surgery (all detailed elsewhere). Generally we start with less invasive treatment methods prior to considering procedures or surgery. There is ongoing research looking at other treatment options in addition to pressure lowering, however they are not well established yet and not part of basic glaucoma management at this time. We are optimistic that other treatment options will be available in the future.
