Causes of Diabetic Retinopathy

What are the causes of diabetic retinopathy and long-term diabetes? Changes in blood-sugar levels is the main culprit. People suffering from diabetes generally develop diabetic retinopathy after at least ten years of having the disease. Once you are diagnosed with diabetes, it is essential to have an eye exam once a year or more.

In the early stage of diabetic retinopathy, called background or non-proliferative retinopathy, high blood sugar in the retina damages blood vessels, which bleed or leak fluid. This leaking or bleeding causes swelling in the retina, which forms deposits.

In the later stage of diabetic retinopathy, called proliferative retinopathy, new blood vessels begin to grow on the retinal. These new blood vessels may break, causing bleeding into the vitreous, which is the clear gelatinous matter that fills the inside of the eye. This breakage can cause serious vision difficulties. This form of diabetic retinopathy can cause blindness, and is therefore the more serious form of the disease.

It is not hard to greatly reduce your risk of diabetic retinopathy by following some simple steps and being aware of your overall health. The most important factor you can control is maintaining your blood sugar at a healthy level. Eating a healthy diet will help greatly in controlling blood sugar levels. A regular exercise regimen is also a great help. Finally, make sure to listen to your doctor’s instructions.

Armstrong & Small Eyecare Centre - COVID-19 Update - March 18, 2020

Due to the recent COVID-19 outbreak, we have made the difficult decision to close starting Wednesday, March 18 and we are hoping (depending on the conditions) that we will re-open on Monday, April 6th.

In our attempts to be as socially distant as possible and to protect you, our staff and all of our families, we recommend staying at home and following all of the precautions that have been set out by the city, province and the nation.

If you have specific questions about glasses, contact lenses or any other non-emergency / non-essential items please email us at info@armstrongandsmall.com and we will do our best to accommodate your request. As part of our services, we are happy to provide you the option of having your contact lenses sent directly to your home. If you currently have items on order, we will be in touch with you to make arrangements.

If you are calling about a specific ocular or visual emergency such as new flashes and/or floaters, a loss in vision or a suspected eye infection, please text or call Dr. Luke Small at 204-299-6587 or Dr. Matt Lepage at 204-573-8039 who are both providing on-call emergency services through our clinic. Please do this prior to going to Misericordia or to a walk-in clinic as we attempt to reduce their patient load at this time. Obviously, if you have been recently traveling or are experiencing any symptoms related to COVID-19, they will be able to direct you where to go for the proper care.

Please stay home as much as possible and stay safe.

Thank you from your Armstrong & Small Eyecare Team.
