OCT Eye Scan in Perth
Optical Coherence Tomography
Advanced 3D Eye Scan Imaging
OCT Scan
Optical Coherence Tomography (OCT) scanning is an essential part of our diagnostic tools. OCT scans provide detailed, 3D images of the retina and optic nerve, allowing for early detection of eye diseases such as glaucoma, macular degeneration, and diabetic retinopathy.

About OCT Scans
Unlike standard eye exams, which assess your vision and eye health on the surface, OCT scanning provides a deeper view of the retina’s internal layers. This allows us to detect early signs of diseases that may not be visible through traditional methods. OCT scanning can reveal subtle changes in your retinal structure long before they impact your sight, making it a vital tool in preventative eye care.
Example of OCT eye disease detection.
Pellucid Marginal Degeneration (PMD), a rare, progressive condition that affects the cornea, causing thinning in the lower part of the cornea and leading to irregular astigmatism and vision distortion.
Scleral lens sitting off the cornea.
We use OCT for the diagnosis of corneal diseases and the fitting of scleral contact lenses.
Who Should Get an OCT Scan?
OCT scanning is beneficial for everyone, but it’s particularly recommended for individuals at higher risk of developing serious eye conditions, including:
- People with diabetes
- Individuals with a family history of glaucoma or macular degeneration
- Patients over the age of 50
- Those experiencing unexplained changes in vision
For these groups, an annual OCT scan is advisable to monitor eye health and catch any changes early.
If you’ve never had an 3-D scan of your eyes, it is extremely beneficial to receive one, as it establishes a baseline against which to measure changes in your eye condition.
What Happens During an OCT Scan?
Preparation: No special preparation is needed for an OCT scan. In some cases, we may use eye drops to dilate your pupils for a clearer view of your retina, but this is rare.
The Scan: You’ll be seated comfortably in front of the OCT machine, resting your chin on a support. You’ll be asked to focus on a green target light while the machine captures detailed images of your retina. The process takes just a few seconds per eye, with no direct contact to your eyes.
Reviewing the Results: Once the scan is complete, your optometrist will immediately review the 3D images with you. These high-resolution images provide a detailed look at your retina and optic nerve, allowing us to detect any abnormalities.
The entire process takes less than 15 minutes, and the images will be saved for future comparisons, ensuring that we can monitor any changes in your eye health over time.
