Since many patients do not experience any symptoms during the early stages of glaucoma, a diagnosis may only be made during a regular eye exam. It is important for patients, especially those with a higher risk of developing glaucoma, to have their eyes checked at least once a year.
Your doctor may perform several different eye exams in order to detect signs of glaucoma. Visual field testing is one of the most common tests performed, and involves creating a map to assess peripheral vision. Blind spots within the peripheral vision are often a warning sign for eye diseases like glaucoma.
The Cirrus Optical Coherence Tomography (OCT) is one of the latest developments in diagnostic technology and is available at North Toronto Eye Specialists. This testing system produces a highly detailed image of the structures and tissue within the eye to assess the thickness and health of the retina, macula, optic nerve and more, all without even touching the eye.
Eye on the latest in retinal diagnostic technology: Optical Coherence Tomography (OCT™)
This high-tech equipment allows physicians to clearly see the inside of the eye and treat problems before they progress. With this tool, we can see a highly detailed image of the eye structure and tissues. It especially allows us to see the back of the eye to better measure the thickness of the retina, macula, and optic nerve This technology helps us to accurately monitor diseases and conditions such as glaucoma, diabetic retinopathy, and uveitis.
- The instrument never touches the eye, so there is no discomfort.
- It provides a detailed analysis of all the layers of the retina in just minutes.
- For glaucoma, the Retinal Nerve Fibre Analysis identifies any glaucoma-related defects well before the patient would notice any symptoms.
