NEW YORK, Apr 21: A new analysis of Medicare records finds dramatic differences across the US in rates of new glaucoma diagnoses, suggesting the eye disease is likely being overdiagnosed in some regions and underdiagnosed in others, researchers said. Looking at all Medicare claims for a seven-year period, the team found glaucoma rates had risen slightly overall, but that people in New England or the Mid-Atlantic states had about 30 percent higher odds than people in the Southeast of being diagnosed with glaucoma—and some 70 per cent higher chances of getting a suspected-glaucoma diagnosis.
