![]() If you have any questions or concerns about your OCT exam, please contact us today. If you have been diagnosed with an ocular disease, an OCT scan will also provide the information needed to monitor treatment. Having regular OCT scans will enable your doctor to compare the images from previous years to detect any abnormalities or thickening of retinal layers. If you are over age 25, or at risk of developing ocular disease, your eye doctor may recommend an OCT exam as part of your annual eye exam. As the laser scans the retina in each eye, you may notice a red line moving across your vision. The OCT will scan each of your eyes, while you fix your gaze on a green target. During the test, you will sit with your chin resting on a support. The OCT scan uses light waves to create an image, similar to an ultrasound that uses sound waves to create an image. This allows us to assess cornea, angles, and corneal thickness. These conditions include dense cataracts or significant bleeding in the vitreous.Īt Falcon Vision Centre, our OCT device allows us to do Anterior Segment OCT as well. Your eye doctor can map and measure the thickness of these layers. OCT allows your optometrist to see the specific layers of your retina through the use of light waves. It cannot be used with conditions that interfere with light passing through the eye. Optical coherence tomography (OCT) is an imaging tool frequently used to take high-resolution images of the back of the eye, your retina. For example, it can detect changes caused by glaucoma. The OCT exam helps our optometrists see changes to the fibers of the optic nerve. Optical coherence tomography (OCT) is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope. OCT is often used to evaluate disorders of the optic nerve as well. Ocular OCT retinal thickness map, right eye Time-domain OCT of the macular area of a retina at 800 nm, axial resolution 3 µm Spectral-domain OCT macula cross-section scan. OCT is useful in diagnosing many eye conditions, including: These retinal diseases include age-related macular degeneration (AMD) and diabetic eye disease. They also provide treatment guidance for glaucoma and diseases of the retina. This allows us to map and measure their thickness. With OCT, our optometrists can see each of the retina’s distinctive layers. The OCT scan uses a laser (without radiation) to obtain higher resolution images of the layers of the retina and optic nerve.
