3 Ways Diabetes Can Affect Your Vision and Eyes

Diabetes-2_640x350

Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it's important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor.

But First, What Is Diabetes?

Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn't produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.

Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future?

Our Milton eye doctor has prepared the following answers to your questions about eye disease.

What's the Link Between Vision and Diabetes?

Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels.

If you start to notice blurry vision, make an appointment with Dr. Alisa Khan as soon as possible."

The 3 Ways Diabetes Impacts Vision

Cataracts

While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective.

Glaucoma

Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss.

Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.

Diabetic Retinopathy

Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.

Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.

The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact Milton Eye Care in Milton to set up your eye doctor’s appointment today.

Dear Patients,

Today, under directions from the College of Optometrists of Ontario, we have made the difficult decision to immediately suspend all non-urgent care,  due to the COVID-19 pandemic. Our doctors will still be accessible for ocular emergency assessments case by case. The clinic is closed.

All non-urgent appointments will be canceled and rescheduled for a later date. For urgent care please DO NOT call or come to the clinic, but send an email to: info@miltoneyecare.ca for appropriate triaging.

For patients who need to order contact lenses, please continue to place your order request on our website at www.miltoneyecare.ca. We encourage a 6-12 months’ supply of contact lenses to be ordered.

What consists of an emergency: Ocular Emergencies require an urgent visit within 24-48 hours. Please email our office should you experience:

  1. Chemicals splashed into the eye within the last hour
  2. Sudden loss or decrease in vision, or the appearance of a cloudy veil in front of the eye
  3. Foreign body in the eye, ocular injury or forceful trauma to the eye or surrounding area
  4. Sudden onset of halos around lights; especially if associated with a red painful eye or brow
  5. Sudden onset of flashing lights or floaters
  6. Sudden onset of double vision
  7. Red eyes with pain, light sensitivity or pus discharge
  8. Swelling of eyelid

If you are not sure if you are experiencing an ocular emergency please email our office at info@miltoneyecare.ca
