Optical Coherence Tomography (OCT) is a non-invasive test that uses light to produce a 3D model of the back of your eye (called the retina). The OCT machine creates a high-resolution cross-sectional (layer-by-layer) depiction of the back of your eye. Digital retinal imaging produces a high-quality photograph of the back of your eye.

Your optometrist uses an OCT image and digital retinal imaging in the early detection of ocular health concerns. For example, OCT images help your optometrist detect, monitor and treat glaucoma, vascular disease, macular degeneration and various other retinal diseases. Regular eye exams and preventative education can help keep health problems from developing.


MYAH Machine Eye Exam Waterloo

At Insight Eye Care, we use an instrument called MYAH to measure the length of your eye (optical biometry), map the surface of your eye (corneal topography), photograph the anterior (front) segment, and perform multiple tests to assess dry eye. 

This device supports the detection, monitoring and treatment of myopia (nearsightedness), irregular refractive surfaces such as keratoconus and corneal degenerations, dry eye and other conditions that impact the surface of your eye, the cornea. It is also integral to the proper fitting of specialty contact 

Visual Fields Explained

A visual field test measures the size and sensitivity of your side, or peripheral, vision. It can help detect certain patterns of vision loss that occur when an eye disease is present. At all times during the test, you will have one of our staff members available to support you through the process. To sum it up, a visual field test provides information on how the brain is processing visual information!


Visual field testing is an important part of obtaining and maintaining a driver’s licence. In Ontario, you must meet a standard for peripheral vision that is set by the Ministry of Transportation. Instead of taking the vision test at a Service Ontario site, you can complete the testing at Insight Eye Care. This may reduce the pressure of completing a test in a new environment. You can learn more about the standard on the Government of Ontario’s Website.


If you want to learn more about the science behind visual field testing, then take a look at this article. The Eye Physicians and Surgeons of Ontario explain how the visual field test works and what conditions it can detect.
