At Andrea Kay Opticians, we invest in the very best diagnostic technology to protect your sight. That is why we offer Optical Coherence Tomography (OCT) alongside digital Retinal Photography at our Stockport practice. Similar to an ultrasound but using harmless light waves, our state-of-the-art 3D OCT scanner takes a microscopic cross-section image of the back of your eye. This hospital-grade technology allows us to look beneath the surface of your retina, identifying early signs of eye conditions years before they would be visible during a standard eye test.
The Difference Between OCT and Retinal Photography
To provide the ultimate standard of eye care, we utilise two advanced imaging methods together:
- Digital Retinal Photography: Captures a high-resolution 2D photo of the surface of your retina. This acts as a visual permanent record of your optic nerve, blood vessels, and macula, allowing us to compare images from year to year to spot minor changes.
- 3D OCT Scanning: Takes retinal imaging to the next level. Instead of just looking at the surface, the OCT scan cuts a 3D cross-section through the layers of the retina. This allows us to map and measure the thickness of each individual layer, revealing issues hidden beneath the surface.
What Can an OCT Scan Detect?
By looking deep into the structure of your eye, we can diagnose and monitor serious visual health conditions much earlier than standard optometry clinics. Early detection is key to preventing vision loss. Conditions detected include:
- Age-Related Macular Degeneration (AMD): OCT can detect the very early stages of AMD, differentiating between the 'wet' and 'dry' forms to ensure immediate, appropriate management.
- Glaucoma: Glaucoma damages the optic nerve, often without symptoms until irreversible sight loss occurs. OCT measures the nerve fibre layer thickness, identifying damage up to 4 years before standard visual field tests.
- Diabetic Retinopathy: Scans show early leaking of fluid or swelling in the macula caused by diabetes, allowing for early intervention.
- Macular Holes & Vitreous Detachment: Evaluates the gel-like substance inside the eye and how it interacts with the retina.
OCT & Retinal Scan FAQs
What is an OCT scan, and is it painful?
An OCT scan is a completely non-invasive, quick, and painless test. You simply rest your chin on a support and look at a target light while the scanner takes a series of rapid light-based images. There is no physical contact with your eye and no bright flashes.
Should I upgrade my eye test to include an OCT scan?
We highly recommend OCT scanning for all adults, particularly those over 40, anyone with a family history of glaucoma or macular degeneration, and individuals with diabetes or high blood pressure. It acts as an essential "early warning system" for your eyes.
