Optical Coherence Tomography 

Optical Coherence Tomography (OCT) is a non-invasive imaging technology commonly referred to as an OCT scan. It provides high-resolution cross-sectional images of the retina, which is the light-sensitive area at the back of your eye, as well as other layers inside the eye.

Our state-of-the-art OCT technology enables us to capture clear and detailed images of the deepest layers of the eye in just a few seconds. During the scan, your Optometrist can visualize not only the retina but also the vitreous, choroid, sclera, macula, and optic nerve. It provides a comprehensive view of the internal structures of the eye.

To better understand the benefits of an OCT scan, let’s use an analogy. Traditional two-dimensional fundus photography allows us to see the top of a cake and the icing. However, with the three-dimensional imagery produced by the OCT scan, we can slice the cake in half and examine all the layers inside. This level of detail allows us to differentiate between the layers within the retina and measure retinal thickness.

By utilising this remarkable technology, our Optometrists can detect and diagnose various retinal diseases and conditions at an early stage. Examples include Glaucoma, Diabetic Retinopathy, Detached Retina, Age-Related Macular Degeneration, and Macular Holes. In fact, OCT scans have the potential to detect Glaucoma up to four years earlier than other methods. Detecting these conditions early allows for effective management and can help prevent potential sight loss.

An OCT scan is similar to a CAT or MRI scan you may encounter in a hospital, but it focuses solely on the eyes. It utilizes an invisible wavelength of light to capture an impressive number of scans per second, up to 100,000. These scans are then compiled into a highly accurate layered image, providing your Optometrist with a comprehensive view of the structures at the back of your eye.

At New Vision Opticians, we embrace the capabilities of OCT technology to ensure a thorough assessment of your eye health and early detection of any potential issues.
