One of the most significant advances in modern optometry is the routine use of Optical Coherence Tomography (OCT), a non-invasive retinal imaging technology that was once only available in hospital ophthalmology departments. At Prime Optometrists Auburn, OCT imaging is included as part of our comprehensive eye examination.
What Is OCT Imaging?
OCT uses low-coherence light waves to produce high-resolution, cross-sectional images of the retina and optic nerve, similar in concept to how ultrasound works, but using light instead of sound. The result is a detailed 3D map of retinal layers with micron-level resolution that cannot be obtained by any other non-invasive method.
The scan takes approximately 5 seconds per eye, is completely comfortable (no contact with the eye), and provides a permanent digital record for comparison at future visits.
What Can OCT Detect?
Glaucoma
Glaucoma causes damage to the optic nerve and retinal nerve fibre layer (RNFL), often before any visual field loss is detectable. OCT can identify RNFL thinning years before conventional visual field testing, allowing treatment to begin while vision is still fully preserved. Glaucoma is a leading cause of irreversible blindness in Australia, and early detection is the single most important factor in preventing vision loss.
Macular Degeneration (AMD)
Age-related macular degeneration affects central vision and is the leading cause of vision loss in Australians over 50. OCT can detect drusen deposits, geographic atrophy, and sub-retinal fluid associated with wet AMD, often before the patient notices any visual symptoms. Early detection dramatically improves treatment outcomes.
Diabetic Retinopathy
Patients with diabetes are at high risk of retinal vascular changes and macular oedema. OCT provides quantitative measurement of macular thickness, making it an essential tool in diabetic eye monitoring.
Epiretinal Membranes & Macular Holes
Subtle structural changes at the macula, including epiretinal membranes and early macular holes, are clearly visible on OCT before they cause significant visual disturbance.
OCT vs. Standard Retinal Photography
Standard fundus photography captures a 2D image of the retinal surface, useful, but limited. OCT provides a true cross-sectional view of all retinal layers, revealing pathology that is completely invisible to fundus photography or direct ophthalmoscopy.
At Prime Optometrists, we use both technologies in combination for the most comprehensive retinal assessment available in an optometry setting.
Is OCT Included in My Eye Test?
OCT imaging is included as part of our standard comprehensive eye examination at Prime Optometrists Auburn, it's not an optional add-on or extra fee. We believe every patient deserves access to the best available diagnostic technology.
Comprehensive eye examinations are bulk billed under Medicare for eligible patients with a valid Medicare card.
“OCT has fundamentally changed what we can detect at an eye test. We now routinely find early glaucoma and macular disease in patients who had no symptoms and would never have suspected a problem. That's the power of modern diagnostic technology.”
