We’re committed to ensuring that you receive the highest standard of care. Let’s explore how an OCT scan works, the range of conditions it can help diagnose, and the benefits it can provide for your eye health.
What is an OCT scan?
Optical coherence tomography (OCT) is an advanced imaging technique that revolutionises the way we assess and diagnose eye conditions. This non-invasive scan provides insights into the intricate structures of your eyes, aiding in early detection, precise diagnosis, and effective management of various eye conditions.
How Does an OCT Scan Work?
OCT utilises light waves to create high-resolution cross-sectional images of the retina, optic nerve, and other structures in the eye. Your eye is scanned with near-infrared light, and the reflected light is measured to create detailed images providing valuable information about the thickness, texture, and integrity of different layers within the eye.
What are the Benefits of OCT?
OCT offers several benefits.
High resolution
High-resolution images of the eye’s internal structures enable precise evaluation and diagnosis of eye conditions.
Non-invasive
Non-invasive and painless, unlike some imaging techniques with invasive procedures, OCT is comfortable for patients of all ages.
Early detection
OCT can detect subtle changes in the eye’s structures invisible during a routine eye exam, enabling early detection of eye diseases.
Monitoring progression
By monitoring the progression of eye conditions, OCT enables the assessment of treatment efficacy and informed decisions about patient care.
Customised treatment
Through detailed information about the eye’s anatomy, OCT helps us develop personalised treatment plans tailored to each patient’s needs.
What Conditions Can an OCT Scan Diagnose?
OCT is used to diagnose and manage a wide range of eye conditions.
Macular degeneration
OCT can detect and monitor changes in the macula, the central part of the retina responsible for sharp, central vision, affected by age-related macular degeneration.
Glaucoma
OCT measures the thickness of the optic nerve fibre layer, helping to diagnose and monitor glaucoma, which damages the optic nerve.
Diabetic Retinopathy
OCT can detect signs of diabetic retinopathy, a complication of diabetes that affects the blood vessels in the retina.
Retinal detachment
OCT can identify retinal detachments by visualising changes in the retina’s structure and position.
