Diabetic Retinopathy Detection and Prevention Dr. David Maberley, MD, MSc. (Epid), FRCSC, Ophthalmologist

Duration: 2:00

If you have diabetes, your risk of diabetic retinopathy increases based on how well you control your general health. If you can manage your blood sugars well and keep them well controlled, and manage your A1C levels, if you can keep your blood pressure low and controlled, and if you can manage your serum cholesterol levels, then your risk of developing diabetic retinopathy will be significantly reduced. And that's an important piece for patients with diabetes to discuss with their family physicians.

Now, assuming that you're doing the best you can with your systemic control, then you still need to have your eyes examined, and that process would require going to see an ophthalmologist, having dilating drops put in your eyes so the retina can be examined in properly. You would then sit at a high powered microscope, have your retinas examined, often with a headlamp microscope as well, and depending on what was seen, supplementary testing might be necessary. Now many times this testing can be performed the same day. It would include such a test as a fluorescein angiogram dye that is injected into your arm where photos are taken of your eye. There's a laser photograph tests that can be done to look at the thickness of the retina if we're worried about leakage of fluid into your central vision area. And really those are the main tests that we would do to look at your eye in conjunction with the eye exam to diagnose diabetic retinopathy. Your pupils will be dilated during the process, so bringing a pair of sunglasses with you or having someone drive you to pick you up and take you home is probably a good idea.

Once you're seen by your ophthalmologist, if testing is required, depending on the facilities available to that individual, there may be an opportunity for performing your tests the same day and even possibly treatment the same day so that your treatment if you need it can be initiated as quickly as possible for your diabetic retinopathy.

If you have questions or further queries about diabetes and diabetic retinopathy, please talk to your family physician or your local ophthalmologist

There are two types of diabetic retinopathy.

Explanation:

There are two types of diabetic retinopathy: early diabetic retinopathy and advanced diabetic retinopathy.

1

Diabetic retinopathy usually affects one eye.

Explanation:

Diabetic retinopathy usually affects both eyes, and anyone with type 1 or type 2 diabetes is at risk of developing diabetic retinopathy.

2

Diabetic retinopathy can be caused by poor blood control management.

Explanation:

Diabetic retinopathy can be caused by poor blood control management. Excess sugar in your blood can lead to a blockage of the blood vessels leading to the retina, cutting off the blood supply.

3

Effectively managing your serum cholesterol levels can help prevent diabetic retinopathy.

Explanation:

If you can manage your blood sugars and A1C levels, keep your blood pressure low and controlled and manage your serum cholesterol levels, your risk of developing diabetic retinopathy will be significantly reduced

4

Steroid injections are not a treatment for diabetic retinopathy.

Explanation:

Diabetic retinopathy treatment includes anti-VEGF medication, steroid injections, vitrectomy to remove vitreous gel and blood from leaking vessels or laser surgery to seal off leaking blood vessels.
