Our Technology in Toronto

The Heidelberg Retina Tomograph (HRT) is a tool for the early detection and management of glaucoma–an often symptomless, sight-threatening disease.

The HRT is extremely valuable in monitoring those with known glaucoma risk. It complements our doctor’s visual examination of the optic nerve, helping us interpret automated visual field analysis and ocular coherence tomography (OCT) scans.

Visual field testing and analysis can be instrumental in quantifying different forms of vision loss and can even help determine where the issue originates—whether in the eye, optic nerve, or brain.

The Humphrey Visual Field Analyzer 3 (HFA3), the gold/standard in automated visual field testing, allows the doctors to choose from various testing strategies to help diagnose—and manage—multiple conditions.

We use the Retinalogik virtual reality automated visual field analyzer for younger patients with known or detected eye conditions. This state-of-the-art technology offers doctors a quick initial screening of the visual field to assess whether a more in-depth evaluation is necessary.

Visual fields are beneficial in detecting many ocular conditions, such as glaucoma & macular degeneration, as well as brain tumors, strokes, some forms of multiple sclerosis, certain retinal pathologies, and cataracts, to name but a few. The tests also allow us to monitor specific systemic issues that can impact the eyes, like medication toxicity caused by certain drugs, notably Tamoxifen and Plaquenil/Hydroxychloroquine.

Optical coherence tomography (OCT) is a noninvasive imaging technology that can capture images of 10 retina layers and some of the choroid below the retina. Unlike ultrasound, OCT uses light rather than sound to generate an image.

OCT measures the thickness of the retinal nerve fibre layer in patients with glaucoma and other optic nerve diseases. It is the most accurate way to detect, diagnose, monitor, and manage macular degeneration and other retinal conditions.

Today, OCT technology is essential for providing the gold standard of eye care. We train all of our doctors to analyze OCT scans and provide you with accurate diagnoses.

Pachymetry refers to the precise measuring of the thickness of the cornea (the clear window of tissue that covers the coloured part of the eye). This value is needed in the diagnosis and management of glaucoma as well in the determination of one’s candidacy for laser corrective surgeries. It is also need in the diagnosis and management of corneal conditions and pathologies.

Meibography is the imaging of the meibomian glands—located on the margins of the eyelids. Meibomian glands can often atrophy and become dysfunctional as we age, contributing to dry eye disease and causing symptoms like stinging, irritation, and fluctuating vision.

By determining the atrophy and dysfunction of these glands, our doctors can detect early warning signs and tailor a preventative treatment plan for those experiencing or not experiencing symptoms.

Our state-of-the-art N3 VR headset, paired with Neurolens diagnostic evaluation software, can detect misalignments between the eyes when focusing on near and far distances. It also assesses how well a person can turn their eyes inward when looking at close objects, like a computer or smartphone.

Misalignments and deficiencies in eye alignment can contribute significantly to complaints of trigeminal dysphoria, leading to symptoms like eye strain, fatigue, headaches, light sensitivity, blurred near vision, and neck/shoulder/upper back discomfort from prolonged computer and smartphone use.

The doctor’s test results and evaluations guide our Neurolens prescriptions so we can help alleviate symptoms and facilitate a return to comfortable everyday vision.
