According to the Centers for Disease Control and Prevention (CDC), the combined economic impact of age-related macular degeneration (AMD), cataracts, diabetic retinopathy, glaucoma, and refractive error among Americans aged 40 and older estimates a total financial burden of major visual disorders of $35.4 billion comprised of $16.2 billion in direct medical costs, $11.1 billion in other direct costs, and $8 billion in productivity losses, in 2004 dollars. Annually, the federal government and state Medicaid agencies pay at least $13.7 billion of these costs.
