Glaucoma leading cause of irreversible vision loss in U.S

In the Health News blog in Ohio's Plain Dealer (1/7), Robert D. Newcomb wrote that in the U.S., "glaucoma is the leading cause of irreversible vision loss." It affects "more than three million Americans," half of which "may not even realize they have the disease." Those at highest risk for the condition include people over age 60, "African Americans 40 or older," and people "with a family history of glaucoma." Glaucoma happens "when the normal fluid pressure inside the eye steadily increases. This can lead to optic nerve damage and reduced peripheral (side) vision." As the condition progresses, "the field of vision gradually narrows, ultimately leading to blindness without treatment." The American Optometric Association (AOA) has a "Vision FAX brochure called Glaucoma Can't Be Prevented, But It Can Be Controlled," which is available by calling 1-800-365-2219 and asking "for brochure #0069."
