Our Topcon 3D OCT (optical coherence tomography) is the latest, most advanced technology to view and analyze the retina. Similar to ultrasound, OCT uses light rather than sound waves. More advanced than retinal photography (which can only view the surface of the retina) the OCT enables us to view the individual layers of the retina. The scan is non-invasive, painless, simple and quick.
The scan the OCT provides is so detailed that it can pick up the very earliest signs of glaucoma - damage to the microscopic nerve fibers in the back of your eye. This makes it possible to pick up glaucoma before it affects your sight, and indeed before it is detectable using more traditional techniques. This makes OCT the definitive screening tool currently available for this condition.
The OCT provides us with highly useful information about several areas of your eye and retina. For example, it is capable of detecting small areas of swelling that can occur at the back of your eye in macular degeneration, as well as small retinal holes, tears or cysts that may be present and not visible with traditional techniques.
