Retinal Vascular Diseases


Retinal vascular diseases stem from localized structural changes in the blood vessels and capillaries in the eye. The health of the walls of small vessels and capillaries in the eye and retina depends on the quality as well as the quantity of the blood supply. Damage can result in a reduction in the blood flow which can cause irreversible changes to the peripheral retina that may not have any symptoms at all. If this damage happens centrally, severe and sometimes irreversible vision loss can arise.

Retinal vascular diseases are a leading cause of blindness in the Western world and require prompt diagnosis and treatment. Annual or bi-annual exams for healthy adults screen for early warning signs of these issues. Common causes of retinal vascular disease that cause vision loss include diabetic retinopathy (proliferative diabetic retinopathy and diabetic macular edema), hypertensive retinopathy, hypercholesterolemia and clotting disorders (vein and artery occlusions), macular degeneration (both “wet” or neovascular, and dry). The top 3 retinal vascular diseases leading to severe sight impairment are wet age-related macular degeneration, diabetic retinopathy, and retinal vein occlusion.



  1. Diabetes is a systemic disease that affects every blood vessel in the body. The eye is the only place these blood vessels can be directly observed, imaged, and evaluated. Vision complications can include diabetic retinopathy and diabetic macular edema. Diabetes also increases your risk of developing other ocular diseases such as cataracts, age-related macular degeneration, and glaucoma that can lead to vision loss and blindness if left untreated. Annual photographic screening for diabetic patients along with testing the peripheral vision, checking eye pressure, and examining the retina and optic nerve using specialized equipment and diagnostic techniques is essential for early detection of issues and covered by Alberta Health Care. Diabetes is the leading cause of preventable blindness in North America. If you are a diabetic and it’s been a year since your last eye exam, call us today for an appointment.
  2. Patients with retinal Artery or Vein Occlusion typically present with painless loss of peripheral or central vision. Prompt evaluation, diagnosis, and in some instances referral is necessary for optimal outcomes. These typically happen because of some underlying systemic health issues. If there is no history of systemic issues, Dr. Louie and Dr. Larson will work with your primary care physician, and sometimes specialists, to help prevent further damage or new issues.
  3. Untreated high blood pressure not only affects the heart and kidney, it can also compromise your eyesight leading to hypertensive retinopathy. The retina is the area in the back of the eye where images focus, and hypertension can cause damage to the blood vessels in the retina leading to vision loss. Uncontrolled hypertension is a leading cause of stroke. People experiencing a stroke may have changes in vision such as uncontrollable eye movements, double vision, blurred vision, or loss of vision.

I called over 20 optometrist offices looking for Dr Larson after he left his old place and I lost the name of the new one. We all had a laugh about it. He is worth every bit of that effort and is FAR, FAR superior to almost every single optometrist I've ever seen and I've had [extraordinarily complex] glasses since I was 6 months old. His passion, kindness and impressive knowledge are just the start of why I'm a loyal client. That's not to mention his front staff whom are all warm, helpful, super friendly and very skilled at fitting glasses. I can't say enough good things. You can't go wrong coming to this place.

I cannot say enough great things about Dr. Louie's top notch service and expertise. My eyes are - let's say - challenging and he always nails my prescription perfectly. His attention to detail and kindness are better than anything I have experienced in all my years visiting eyecare centres. Dr. Louie's staff are so kind and caring and friendly. AND if you are looking for an AMAZHING pair of frames - stop the car right now. As a phenomenal photographer - just put your "face" in his hands and he will select the best frames for you. Be forewarned though - you will have to fight off endless compliments on your glasses!! Thank YOU so much!! My whole family loves visiting you for their eyecare needs.

Frequently Asked Questions

You should see an optometrist when there are changes in vision, problems with eye movement or when headaches or eyestrain occur regularly. Children’s eye exams begin at six months old, adults should get an eye exam every two years, and seniors should get an eye exam every year.

A comprehensive eye exam from Louie Eyecare Centre in Edmonton costs $135. This includes a 3d retinal optomap of the back of the eye. We offer direct billing options with Alberta Blue Cross and Green Shield Canada (GSC). If you are with another insurance provider, you may be required to pay at the clinic and submit your claim to your insurance provider.

Eating a well-balanced diet that includes plenty of fruits and vegetables is one of the best things you can do for your overall health, including your eyesight. Here are some specific foods that are particularly good for your eyes: carrots, dark leafy greens, brightly coloured vegetables, fish, eggs, nuts, and seeds.

Healthy eyes can benefit from many of the same vitamins and minerals that are good for your overall health, including vitamins A, C and E, as well as zinc, lutein, and zeaxanthin. Louie Eyecare Centre can advise you on which supplements may be right for you.

Most people only need an eye exam once a year, but it depends on your age, health and how often you have problems with your vision. Children usually need more frequent exams because their eyes are still developing. Adults older than 65 may also need more frequent exams since changes in the eye and vision occur with age. If you have a family history of eye problems, or if you’re experiencing vision problems, you should visit your optometrist more often. At Louie Eyecare Centre we offer comprehensive eye exams that will help diagnose any potential problems early.

After age 65, you should have an eye exam every year. It’s important to have regular eye exams because your risk for developing age-related eye diseases, such as macular degeneration and cataracts, increases with age. Louie Eyecare Centre can help you keep your eyes healthy as you age.
