Diabetes is the leading cause of blindness in people under age 65. Diabetes can cause severe damage to blood vessels throughout the body. When the blood vessels in the retina become damaged, they may leak fluid, bleed, or lead to the growth of scar tissue. In some patients, the leaking fluid will spread to the macula (the area of the retina for central vision), causing swelling and blurred vision. This condition is called macular edema. All of these changes can cause blurring, distortion, loss of detail vision, floaters, and blindness.
