Technology – Advanced Eye Care

Our Office Offers Automated Visual Field Testing

This Field Test is performed to measure central and peripheral vision loss. We perform it when a patient is at risk for Glaucoma, macular degeneration or other medical conditions. We also administer this test for those who require MTO Ministry or Transportation testing.

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 Pink Sidhu and Associates.

Digital Retinal Imaging & OCT Scans At Our York Eye Care Center

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 York 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
  • Retina Camera

Retinal Camera

Digital Retina Camera – aka fundus camera, refers to photography of the back of the eye. It is non-invasive.

Your retina consists of ten layers. Fundus photography provides a top-down view through these layers. The imaging enables us to clinically photo document and see signs of retinal confusions including diabetes, hypertension, and macular degeneration. Our optometrists in York, Toronto can document developing cataract and optic nerve status. Often it is a tool used to document external parts of the eye as well.

Children under the age of 19 are covered under OHIP once a year for an annual eye exam, and while this advanced imaging isn’t covered under OHIP, we do strongly recommend it for all children’s eye exams.

Optical Coherence Tomography (OCT) +

An additional test that we strongly recommend for all patients is called Optical Coherence Tomography (OCT):


OCT – a non invasive, advanced imaging technology that uses safe, infra-red light to address the eye. It is the the new gold standard of eye care and helps make the invisible “visible” by creating a digitalized cross-section of your retina and optic nerve.

The test itself is quick and painless and only takes a few minutes. In some cases we may need to dilate your pupil using eye drops in order to increase the amount of light let into the eye.

You will be seated in front of the OCT machine, with your head and chin resting on rests (this ensures limited motion during the scan). The equipment will do the rest.


The advanced technology we have in our York optometry practice to view the of the eye in such extraordinary detail gives our eye doctors advantages over offices that don’t invest in these new instruments. Additionally, with the use of this technology, we can detect the onset of eye diseases earlier, and are far better at effectively monitoring their progression over time.

Peripheral Vision Screen – a simple and non invasive assessment of how far right left, up, and down one can see.

What Happens During an Automated Perimetry Test?

The automated perimetry test uses a computer program to test an individual’s field of vision. You will sit and look into a dome-shaped instrument. Our York eye doctor will instruct you to look at an object in the middle of the dome throughout the test. There will also be small flashes of light in different locations around the dome. When you see these flashes of light, you will press a button to acknowledge that you have seen them. The computer program will provide your doctor with a “map” of your visual field. Dr. Pink Sidhu can then use this information to help diagnose problems or order more vision tests.

What Are the Causes of Visual Field Problems?

Visual field problems have a number of causes, including disorders that don’t originate in the eye, but in the area behind the eye, or in the brain – the part responsible for vision.

The results of a visual field test issued to diagnose:

What are the causes of Visual Field Problems

  • Glaucoma
  • Macular degeneration
  • Optic nerve conditions
  • Brain tumor
  • Multiple sclerosis
  • Stroke
  • Temporal arteritis
  • Central nervous system disorders Pituitary gland disorders
  • High blood pressure or related pathology

Dr. Pink Sidhu and Associates may order further eye tests to diagnose a problem.

Corneal Topography

A Topographer is useful to diagnose Keratoconus patients. It is also used for routine Ortho K fittings, and for some patients for their post LASIK or refractive procedures.

This technology is used to image the meibomian glands. It is helpful to diagnose Meibomian Gland Dysfunction, MGD.
