Diabetic
Retinopathy occurs as a result of high blood sugar and can cause blindness if
left untreated. Diabetic Retinopathy is an eye condition that affects people
with diabetes who have high blood glucose over a prolonged period of time. A
high blood sugar level can destroy the blood vessels in the back of the eye,
preventing the retina from receiving the proper amount of nutrients it needs to
maintain vision. (Kristy, 2012)

The
retina is a light sensitive nerve tissue at the back of the eye. As light enters
the front of the eye, the retina converts the light rays into electrical
impulses that travel along the optic nerve to a part of the brain called the
visual cortex. The brain then combines images sent from both eyes to interpret
them as a single three dimensional image. This allows us to perceive depth and
distance. Without the retina, the eye cannot communicate with the brain, making
vision impossible.

In
the early stages of Diabetic Retinopathy, called non-proliferative retinopathy,
these blood vessels leak fluid and distort sight. In the more advanced stage of
diabetic retinopathy, called proliferative retinopathy, fragile new blood
vessels grow around the retina and in the vitreous humor. If left untreated,
these blood vessels may bleed, clouding vision or detaching the retina (Kristy,
2012).
