November is Diabetes Awareness Month

Diabetes is a growing health crisis in North America as an estimated 3.4 million Canadians are currently living with the disease. Chances are it affects you or someone you know. November has been dedicated as a time to spread awareness about the disease, its risk factors and the effects it has on your body, your daily life and the lives of your loved ones.

Diabetes and Your Eyes

Diabetes is a systemic disease that causes fluctuations in glucose (blood sugar) levels which can affect blood vessels throughout the body including those in your eyes and visual system. People with diabetes are at higher risk for blindness than the general population, however with regular eye exams and proper care, most of the complications are minor and treatable.

Minor changes in glucose levels could result in complications such as blurred or double vision, floaters or even visual field loss. These conditions are usually quite treatable. Diabetics are also at greater risk for developing eye diseases such as glaucoma (40% increase risk) and cataracts (60% increased risk). With early detection, both of these conditions can be treated and the majority of vision restored.

Diabetic eye disease often has NO noticeable symptoms or pain, so comprehensive eye exams that include dilating the pupils are essential to detect signs of diabetes. Online vision assessments will not detect diabetic eye disease.

The condition that is the most concerning risk of diabetes is called diabetic retinopathy which can lead to blindness if not diagnosed and treated.

What You Need to Know About Diabetic Retinopathy

Diabetic retinopathy occurs when the tiny blood vessels or capillaries in the back of the eye develop weakened vessel walls. If not treated, the vessels leak fluid and become blocked. This can progress to hemorrhages in the retina, and over time the eye does not receive enough oxygen and nutrients. As a result, new fine blood vessels start to grow. These proliferating vessels leak and can cause further bleeding, scarring and potentially lead to blindness. A special zone in the central retina called the macula is especially susceptible to diabetes. Diabetic macular edema (when fluid seeps into the macula) can cause permanent vision loss if not promptly detected.

There are treatments for stopping the progression of the disease such as laser therapy or intraocular injections, although once damage to vision has occurred, it is often permanent. This is why the condition must be diagnosed and treated early on.

All diabetics should have a regular comprehensive eye exam to catch any early signs of diabetic retinopathy or other vision threatening conditions. Because risk factors vary, speak to your eye doctor about how often you should have an exam. Risk factors for diabetic retinopathy include:

  • Length of time living with diabetes
  • Uncontrolled blood sugar levels
  • High blood pressure
  • Smoking
  • Alcohol consumption
  • Pregnancy
  • Genetics

Although blindness from diabetes is preventable it is still a leading cause of blindness among working-age adults. If you or someone you know has the disease, make sure that proper eye care is a priority.

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.
