What is an OCT Scan?
An OCT (Optical Coherence Tomography) scan is an advanced, non-invasive imaging test that lets us see beneath the surface of your central retina; the delicate tissue at the back of your eye responsible for vision. Using light waves, the OCT creates detailed cross-sectional images of the retina, much like an ultrasound but with far greater precision. This allows us to examine the different layers of the retina in microscopic detail, something that cannot be seen with standard eye examinations alone.
How OCT Complements Optomap
The Optomap provides a wide-field image of your retina, giving us a broad overview and helping to detect conditions affecting the outer areas of the eye. OCT works hand-in-hand with this by offering a deeper, layer-by-layer view of the central retina and optic nerve. Together, these scans give a much more complete picture of your eye health – Optomap shows us the landscape, and OCT shows us the fine details hidden beneath the surface.
What Can OCT Detect?
OCT is especially valuable in detecting early changes linked to conditions such as glaucoma, age-related macular degeneration, diabetic eye disease, and retinal swelling. Often, these problems develop without noticeable symptoms in the early stages, but OCT can pick up the very first signs of change before vision is affected. Detecting these issues early means treatment can be started sooner, often protecting and preserving sight for the long term.
Why Choose an OCT Scan?
Investing in an OCT scan means investing in your future eye health. While it is an additional service, the benefits are significant: earlier detection, better monitoring, and peace of mind knowing that your eyes are being checked with hospital-grade technology. By choosing to include an OCT scan in your eye examination, you’re giving yourself the best chance of maintaining healthy vision for years to come.
