Eye On Evanston Uses Advanced Technology for the Best Eye Exam

Digital Retinal Imaging & OCT Scans

Eye On Evanston uses 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 your NW Calgary eye doctor a permanent record of the condition and state of your retina.

This is very important in assisting your 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 in NW Calgary

Digital Retinal Imaging allows your eye doctor 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

Optical Coherence Tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina, the light-sensitive tissue lining the back of the eye.

OCT is like an ultrasound of your eye, it gives you a picture of the back of the eye below the surface of the retina. The instrument looks at all the layers of the retina and the optic nerve. The OCT is particularly excellent at evaluating disorders effecting your central vision in the area of your retina called the macula and optic neoctrve disorders like glaucoma.

The OCT technology is the most revolutionary piece of equipment for optometrists to evaluate eye disorders of all parts of the eye in the last fifty years. Patients are wowed by the ability to see the different layers of the back of their eyes, just by putting their head on a chin rest and having them look straight at the target. They can appreciate the high-end technology which is not available at many optometrist offices. It reduces unnecessary referrals to specialists thereby reducing costs to our patients.

Patients who are at a high risk of macular degeneration or glaucoma can now routinely have OCT performed. Our patients are most grateful to have their extensive eye-care done at our office without requiring visits to external specialists. Optical Coherence Tomography (OCT)

Visual Field Testing

A visual field test measures how much ‘side’ vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.

Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.

Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.
