The American Glaucoma Society seeks to ensure the highest quality care for patients with glaucoma. The surgical care of the glaucoma patient requires the skills and judgment of physicians who have graduated from the rigorous training and hands-on experience provided by a complete curriculum in allopathic or osteopathic medicine with subsequent subspecialty training in Ophthalmology. Surgery for glaucoma includes the use of laser, incisional surgery with and without devices, injections into or around the eye, and should be performed only by physicians who have been licensed and credentialed in allopathic (MD) or osteopathic (DO) medicine.
