What is OCT scanning?
Optical Coherence Tomography (OCT) is a sophisticated scanning system that provides highly detailed images of the internal structures of the eye. This technology provides highly detailed images of the retina as well as the optic nerve. These cross-sectional images are viewable in 2D and 3D, allowing for topographical mapping of the eye including macular thickness.
Various pathology can be detected using this non-contact technology such as Glaucoma and Keratoconus. Some OCT products boast additional features such as Microperimetry. OCT is also extremely helpful to measure the changes in a patients eyes overtime and can be beneficial pre and post-operatively for cataract patients.
Optical Coherence Tomography or OCT as it is more commonly known is a sophisticated scanning system that produces highly detailed images of the retina. It is often likened to an MRI or x-ray of the eye. This scan allows our optometrist in Colorado Springs to see detailed images of the retina (the inner most layer of the interior eye), enabling them to accurately detect, monitor and control changes to the retina. This procedure is currently the only one that shows in-depth images of the eyes internal structures. Other procedures only show the surface of these structures.
How does it work?
An OCT scan only takes a few minutes. No discomfort will be experienced. A special camera using laser light takes an image of your retina then uploads the OCT images to a computer. We store these images electronically so that we can monitor changes over time.
The scan is similar to a fingerprint and provides us with a wide view to look at the health of your retina. The retina is the part of your eye that captures the image of what you are looking at, similar to film in a camera.
OCT and Early Detection of Eye Health Problems
Many eye problems can develop without you knowing. You may not even notice any change in your sight. But, diseases such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.
