Have you ever been referred to an eye specialist’s office for additional testing? One of these tests may have been an OCT. Have you ever wondered why your eye doctor has recommended this test and what it is for?

OCT, or Ocular Coherence Tomography, is a non-invasive and painless diagnostic instrument used to create an image of your retina and optic nerve. While similar to a CT scan in the way that it produces images of your internal body structures, the OCT uses light—instead of radiation—to rapidly scan the layers of your retina and create a 3D cross-section of the area. What that scan reveals about the condition of your retina can be interpreted by an Optometrist or Ophthalmologist.

Flowers are blooming and spring is in the air! As pollen spreads, people afflicted by seasonal allergies begin to suffer. Allergens can cause redness, swelling, itching and watery eyes due to histamine. Although histamine is a normal component of the body, when released, it causes an inflammatory response.

Seniors are not exempt from bothersome allergy symptoms and often have complicating factors such as chronic diseases, making it difficult to manage and treat. Avoid planning outdoor activities when outdoor allergens are particularly high. If you must go outside, remember to wear sunglasses to avoid eye irritation.

Over 3 million people in Canada are diabetic and over 5 million are pre-diabetic. Diabetes can affect the eyes in many ways, although the first symptom diabetics may encounter is fluctuation in vision. As the blood sugar levels in the body increase, it may cause a temporary hyperopic shift in a person’s prescription. While that may not seem too serious, every time it occurs it causes the lens within the eye to fill with water, which changes the uniformity of it. Eventually, this may lead to a cataract or opacity of the lens as well as a permanent decrease in vision. The only way to restore vision would be through surgery.
