Retinopathy is damage to the retina, the innermost layer in the eyes. This can lead to loss of vision. Over time, high levels of glucose in the blood can damage the retina. The retina is a sensitive layer at the back of the eye that has many tiny blood vessels. These blood vessels can become damaged and leak. New blood vessels form in the retina to compensate. These blood vessels can easily leak too. Imagine how easy it is to drink water through a thin straw. Now imagine how much harder it is to drink a thick milkshake through the same straw. Not easy at all! In the long term, these damaged blood vessels causes problems with vision and if left untreated can stop you seeing. The longer you have unmanaged diabetes, the more likely you are to experience eye problems.
There are many things you can do to help keep your eyes healthy and help prevent diabetic eye complications.
