Our Technology

Digital Retinal Photography

The clarity of a high resolution image of your eye is a game changer.

Digital Retinal Photography Lets Us See So Much

The advanced technology we have in our office to view the back of the eye in such extraordinary detail gives our eye doctors advantages over offices that don’t invest in these new instruments. Because of it we can see the development of many eye diseases when they are in their infancy, enabling us to catch these concerns earlier. As you know, when it comes to eye diseases, early detection and treatment is key.

Results are immediate; digital photography eliminates the wait. We are able to immediately use the information provided by digital retinal photography to infer problems, make assessments, and provide us insights into the state of your eye health.

Immensely effective for the detection of many eye diseases. As you can imagine, the ability to see – in ultra-high resolution – what is happening to the eye facilitates easier and more accurate diagnosis of many eye diseases. These include:

  • Glaucoma
  • Age-Related Macular Degeneration
  • Retinal tears and detachments
  • Optic strokes
  • And many others

During your next eye exam, our Optometrist will go over the results and indicate what they are seeing and where.

Often, we see the signs of high blood pressure or diabetes before they are even on our patients radar.

Digital retinal photography is also known as digital retinal fundus photography. Fundus photography simply refers to photography of the back of the eye.

Your retina consists of ten somewhat translucent layers. Fundus photography provides a top-down view through these layers to the back of your eye. Using fundus photography, we can detect and then monitor the development of many eye diseases – as mentioned above – in a way that simply would not be possible without it.

OCT Imaging

We are excited to introduce the new Zeiss Clarus 500 Widefield Fundus Camera to NTOC! This innovative tool can take 210-degree panoramic photos which allows our doctors to see down to 7 microns and captures retinal changes at the earliest stage. There are only a few of these cameras in Canada, and your eye health means so much to us, that we wanted to invest in one. All ages and all abilities can partake!

Using the Cirrus HD OCT, we can diagnose and control retinal problems before any avoidable damage is done. Cirrus HD OCT Provides Insight Into Your Eyes in Ways Not Otherwise Possible. OCT imaging is non-invasive and is totally non-contact. The equipment does not touch your eye in order to take its measurements. Instead, it uses light waves to create a cross-section of your anterior sections of your retina, cornea, iris, and optic nerve.

What is OCT Imaging and How Does it Work?

Ocular coherence tomography (OCT) is an advanced imaging technique that allows our Optometrists to see extremely detailed cross-sections of the part of the eye they are measuring.

They work by using infrared light – which is safe for your eyes and causes no damage – to scan the area the Optometrist is looking at. The scan measures the thickness of the retina and its individual layers.

OCT imaging is an effective tool for the detection and monitoring of:

  • Glaucoma
  • Age-related macular degeneration (AMD)
  • Diabetic retinopathy
  • Numerous optic nerve disorders

The test itself is 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 visible area.

You will be comfortably seated in front of the Cirrus HD OCT, with your head resting on the head rest (this ensures limited motion during the scan). The equipment will do the rest, taking around 10 minutes to complete the scan.

The information provided by the OCT scan will directly inform your treatment plan. Once a proper diagnosis is made, we will then outline what the appropriate next steps are.

Visual Field Testing

Visual field testing is simple and accurate, allowing us to gain insight into eye diseases like Glaucoma and neurological conditions like a stroke or brain tumour.

A Simple But Important Diagnostic Tool

Visual field testing measures your field of vision, and is the gold standard for detecting Glaucoma and following its progression. It is a simple, non-invasive test to perform.

  • How far up, down, left, and right you are able to see without having to move your eyes, neck, or head
  • Visual accuracy across your visual field
  • Responsiveness to various stimuli/light across your visual field

A visual field test does not require any activity that would cause discomfort. It involves placing your head on a cushion and following our instructions as we test various aspects of your visual field. When performed properly, a visual field test can give us important information about your eye health.

When undergoing a visual field test, it is imperative that you provide accurate information regarding what you are seeing. Often, patients will try to “do well” on the test, making the data collected unreliable as a result. So long as you are honest in your responses, the visual field test will produce an accurate result.

A visual field test can provide information on:

  • The development of Glaucoma
  • Various eyelid conditions (ptosis, drooping)
  • Optic nerve damage

A visual field test is quite low-tech in comparison to some of the other testing equipment we have access to, but it remains an important diagnostic tool.

During a visual field test we will perform:

  • Confrontation visual field test – While standing or sitting still, and with one eye covered, we will place objects in your field of vision and ask you to provide feedback on what you’re seeing.
  • Amsler grid test – While looking at a fixed point within a larger square grid, we will ask you to interpret various points on the grid. This test helps us determine visual acuity across various points in your field of vision.

What You'll Find at New Tecumseth Optometry

Our clinic is completely wheelchair accessible and has been recently renovated to update our exam and testing rooms. You’ll also find our eyewear boutique showing off many of the latest styles of frames and sunglasses from trendy new brands, as well as your old favourites from brands you already love.

Thanks to our on-site lab, we are able to significantly reduce the lead time between when you receive your prescription and when your new set of glasses or sunglasses are ready. Using our Optics Lab, we are better able to monitor quality of the lenses and frames that we offer our patients and clients.

At NTOC we have the most advanced imaging equipment, and our newest addition the Zeiss Clarus 500 Widefield Fundus Camera is changing the game! This camera takes 210-degree panoramic photos which allows our doctors to see down to 7 microns and captures retinal changes at the earliest stage. It is a very useful tool for early diagnosis and management of eye diseases including AMD, diabetic eye disease, and glaucoma.
