People with diabetes mellitus are not able to process sugar properly. When diabetes is not controlled, high blood sugar levels can cause damage to the blood vessels in the retina. This condition is known as diabetic retinopathy and can be sight threatening. Diabetes also increases the risk of developing cataracts and glaucoma. Because of the potential for loss of vision, it is very important for diabetics to have yearly eye exams.
In the early stages of diabetic retinopathy, many do not notice a change to their vision because there are little to no symptoms. If an eye doctor does not catch the disease early, one could sustain mild blurriness at near or in the distance, as well as floaters. In severe cases a sudden loss of vision may occur.
A dilated exam by an Eye M.D., using special lenses to evaluate the condition of the retina, is necessary for early detection of diabetic retinopathy. If found early enough, the progression of this disease may be arrested with treatment.
