When booking an eye examination, you may have heard your optometrist mention an OCT eye scan. But what is OCT, and why has it become one of the most important advances in modern eye care technology?
OCT stands for Optical Coherence Tomography. It is a quick, painless retina scan that allows your optometrist to look beneath the surface of your retina and optic nerve in remarkable detail. This advanced imaging technology can reveal tiny structural changes that often cannot be seen during a standard eye examination, helping with the early detection of serious eye conditions.
At Parkhurst and Co Styling Opticians, we believe protecting your sight starts with providing the most comprehensive assessment possible.

What Is OCT?
So, what is OCT?
Optical Coherence Tomography (OCT) is a highly sophisticated imaging system that uses light to produce detailed cross-sectional images of the retina and optic nerve.
Think of it as an ultrasound scan for your eyes—but instead of sound waves, it uses light to build incredibly detailed images of the structures inside your eye.
The OCT eye scan is completely non-contact, painless and takes only a few seconds to perform. Simply look at a target while the scanner captures detailed images that allow your optometrist to assess your eye health with exceptional precision.
What Can an OCT Eye Scan Detect?
ne of the greatest benefits of an OCT scan is its ability to detect changes before they begin to affect your vision.
An OCT eye scan can help identify and monitor conditions including:
Glaucoma
Age-related macular degeneration (AMD)
Diabetic eye disease
Macular holes
Epiretinal membranes
Retinal swelling
Fluid beneath the retina
Changes to the optic nerve
Many of these conditions develop slowly and without symptoms. By identifying problems earlier, an OCT eye scan can support earlier diagnosis, closer monitoring and, where necessary, prompt referral for treatment.

Why Is OCT So Important?
Many sight-threatening eye conditions cause no warning signs in their early stages.
For example, glaucoma often develops without pain or noticeable changes in vision until permanent damage has already occurred. Likewise, macular degeneration and diabetic eye disease may begin with subtle structural changes that cannot be seen during a routine examination alone.
By combining your eye examination with an OCT scan, your optometrist gains far more information about your eye health, allowing small changes to be detected and monitored over time.
Early detection can make a significant difference to preserving your vision.
