Digital Retinal Imaging & OCT Scans

We use cutting-edge digital imaging technology to assess your eyes. If detected at an early stage, many eye diseases can be successfully treated without total loss of vision. Your retinal images will be stored electronically, giving your eye doctor a permanent record of the condition and state of your retina.

This technology is very important in assisting our NW & SW Calgary optometrists to detect and measure any changes to your retina each time you get your eyes examined. It is by detecting and monitoring any changes over time that many eye conditions, such as macular degeneration, glaucoma, and diabetic retinopathy, are diagnosed.

Advantages of digital imaging

  • Quick, safe, non-invasive and painless
  • Provides detailed images of your retina and sub-surface of your eyes
  • Provides instant, direct imaging of the form and structure of eye tissue
  • Image resolution is extremely high quality
  • Uses eye-safe near-infrared light
  • No patient prep required


Digital Retinal Imaging

Digital Retinal Imaging allows our Blink Eyewear doctors in the Creekside, West Springs and Crowfoot Calgary locations to evaluate the health of the back of your eye, the retina. A digital camera snaps a high-resolution digital picture of your retina clearly showing the health of your eyes. This digital picture is used as a baseline to track any changes in your eyes in future eye examinations. Digital Retinal Imaging is a critical tool in confirming the health of the retina, optic nerve and other retinal structures.


Optical Coherence Tomography (OCT)

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Like ultrasound, this diagnostic technique uses light (without radiation) rather than sound waves to obtain higher resolution pictures of the structural layers of the back of the eye, similar to a CT scan. These high-resolution pictures provide colour-coded, cross-sectional images of the retina, which are analyzed for any signs of eye disease. 

The OCT scan is revolutionizing early detection and treatment of eye conditions such as diabetic retinal disease, glaucoma, and macular degeneration. It is a noninvasive, painless test and is performed in about 10 minutes right in our office.

Feel free to contact Blink Eyewear to inquire about an OCT at your next appointment.

Visual Field Testing

Types of Visual Field Tests

A confrontation visual field exam is performed with the doctor ‘confronting’ you by either standing or sitting directly facing you. One eye is focused on a set point and the other is completely covered. Our NW & SW Calgary eye care professionals will then ask you to specify what you see in your peripheral view, or off to one side.

A common way of assessing your peripheral field of view is for the tester to hold up a set number of fingers, and ask how many are visible to you while still focused on the object.

Additional exams will be needed if any abnormalities are detected. More comprehensive diagnostic tests are available to get a more in-depth analysis. Here is a list of sensitive tools used to measure the quality of your vision:


Automated Perimetry Tests

There are a number of tests used to measure your ability to perceive objects in various areas within your visual field. Automated perimetry tests involve staring ahead at a light source, while randomly placed, mini flashes of varying intensities are activated. Each time a flash is visible you will instantly acknowledge it by pressing a button.

Vision loss is apparent if you can’t see the flashing lights at any point in the test. You may have blind spots.


Frequency Doubling Perimetry Tests

The optical illusion of upward bars, usually alternating black and white, visual on a screen, is known as frequency doubling. Vision problems that hinder the ability to see these bars at specific frequencies may be the result of optic nerve damage or some other disorder.


Electroretinography Tests

Doctors use electroretinography to measure the electrical activity produced by the retinal photoreceptor cells when the eye is stimulated by a targeted light. An electrode is positioned on the cornea to capture the measurement that is recorded by an electroretinogram or ERG. An ERG is a powerful device used to detect and diagnose a number of eye diseases and other disorders.

About 30% of patients suffer from symptoms of Blepharitis. BlephEx is an innovative procedure that uses a specialized rotating brush to exfoliate the eyelid margins and remove the scurf and debris.
