Diabetes and its complications can affect many parts of the eye. Diabetes can cause changes in nearsightedness, farsightedness, and premature presbyopia (the inability to focus on close objects with age). It can result in cataracts, glaucoma, strabismus (a lack of eye alignment), and decreased corneal sensitivity. Visual symptoms of diabetes include fluctuating or blurring of vision, occasional double vision, night vision problems, and flashes and floaters within the eye. The most serious eye problem associated with diabetes is diabetic retinopathy.
What is diabetic retinopathy?
Diabetic retinopathy occurs when there is a weakening or swelling of the tiny blood vessels in the retina or back of your eye, resulting in blood leakage, the growth of new blood vessels, and other changes. If diabetic retinopathy is left untreated, blindness can result.
How is diabetic retinopathy treated?
In the early stages, diabetic retinopathy can be treated with laser therapy to seal leaking blood vessels. In more advanced cases, surgery inside the eye may be necessary. Early detection of diabetic retinopathy is crucial.
