Technology – Advanced Eye Care

We use the most up-to-date technology to ensure the best eye care possible. Here are some of the different types of tests and equipment you may experience on a visit to Blink Eyewear.

Digital Retinal Imaging & OCT Scans

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

This is very important in assisting our Northwest Calgary optometrist to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as glaucoma, diabetic retinopathy and macular degeneration are diagnosed by detecting changes over time.

The advantages of digital imaging include:

  • 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-infra-red light
  • No patient prep required

Digital Retinal Imaging

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

Optical Coherence Tomography (OCT)

OCT

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.

A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to an CT scan of the eye. It works using light without radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease.

With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.

An OCT scan is a noninvasive, painless test. It 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 Calgary eye care experts 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, an innovative procedure conducted in controlled environments, enables clinicians to actively treat the onset of Blepharitis in patients. Read more about BlephEx here.
