High blood sugar and high blood pressure, diabetes can hurt four parts of the eye:
Retina. The retina is a membrane that covers the back of the eye. Retinal function is to detect the light entering the eye.
Vitreous. The vitreous is a jelly-like fluid that fills the back of the eye.
Lens. The focus is on the front of the eye. The lens focuses light onto the retina.
Optic nerve. The optic nerve is the main nerve of the eye to the brain.
Damage to the retina occurs slowly. The retina is very small blood vessels are easily damaged. Having high blood sugar and high blood pressure for a long time can damage the small blood vessels.
First, these blood vessels swell and weaken. Some blood vessels become clogged and do not let enough blood through. At first, you may not have any loss of sight from these changes. Have a dilated eye exam once a year, but vision problems.
