Diabetic eye disease can be quite severe before you have any change in your vision. Diabetes can cause cataracts, glaucoma and lead to damage of blood vessels within the eye. Detection of diabetic eye disease requires dilation of the pupils and a thorough retinal exam. Laser treatment is sometimes required to halt the progression of diabetic eye changes. Severe hemorrhages within the eye may require procedures to surgically remove the blood.
Studies show that good control of diabetes significantly reduces the risk of eye damage.
If referred to the ophthalmologist by your primary care physician, diabetic eye examinations are usually covered by insurance plans. Remember, the amount of time you invest in preventative diabetic eye care is small compared to the reward of preserving your vision for the rest of your life.
