Diabetes is a disease that affects the body's ability to control blood sugar. Too much blood sugar in the body can affect many parts of the body, such as the eyes, heart, kidneys, and blood vessels. The Center of Disease Control (CDC) claims that 90% of vision loss from diabetes can be prevented. Therefore, it is critical that if you or a loved one has diabetes, that they come for an annual eye exam.
How does diabetes affect your sight? Uncontrolled blood sugar can make shifts in your glasses prescription, cause cataracts, cause diabetic retinopathy with or without macula edema, and possibly cause glaucoma. The endpoint is blindness if not monitored or controlled. If there are signs of diabetes in the eye, the severity of damage will determine whether you will be monitored more closely or referred to a retinal specialist.
You can expect the doctor will recommend dilation of the eyes with drops to get better views of the retina.
