When diabetes affects the small blood vessels in the part of the eye called the retina, this is known as Diabetic Retinopathy. In the early stages of Diabetes, Diabetic Retinopathy will not affect your sight. However, if the changes get worse, eventually your sight will be affected. Untreated diabetic retinopathy is one of the most common causes of blindness in the working-age population.
A dilated eye examination allows your opthalmologist to see the retina.
Eyedrops will be used to dilate your pupils, which will make it easier to see the back of the eye. When your pupils are dilated, your optometrist will shine a bright light into your eyes and examine them.
