Diabetic eye exams that catch changes early
A dilated eye exam at least once a year, and treatment when diabetes starts to affect your retina.
In short: diabetes can damage the small blood vessels in the back of the eye, often with no symptoms at first. A dilated exam at least once a year finds changes early, when treatment best protects your sight.
What diabetes does to the eye
Blood vessels in the retina can leak, causing swelling in the center of your vision (macular edema). Over time, fragile new vessels can grow and bleed, which can cloud vision or pull on the retina.
Signs to watch for
- Often nothing at all in the early stages
- Blurry vision that comes and goes
- New floaters or a sudden cloud over your vision, which needs a call to us right away
Who should be checked
Everyone with type 1 or type 2 diabetes, at least once a year, even when vision seems fine. The risk is higher the longer you have had diabetes, when blood sugar is hard to control, and during pregnancy. If you have diabetes and are planning a pregnancy, come in for a baseline exam.
What is happening inside your eye
The retina is fed by tiny blood vessels. High blood sugar weakens them so they leak fluid or close off. The eye then grows fragile new vessels that can bleed into the vitreous gel or pull on the retina.
