Optometry technology is continually improving. As an optometry practice that strives to remain at the forefront of the industry, Abernethy Owens is proud to offer a wide range of professional optical services and cutting-edge, advanced diagnostic equipment to diagnose and treat eye conditions in their earliest stages. Read on to discover more about some of the latest innovations in optical imaging.
Digital Retinal Photography / Ocular Fundus Photography
Also referred to as Digital Retinal Scanning, this uses a digital camera to take and record high resolution, full-colour images of the retina. This two-dimensional form of retinal imaging provides important documentation on the condition of your eyes at the time of each examination. Assessing the optic nerves, blood vessels, retina, and macula, it is essential for early detection, and monitoring of many retinal conditions and diseases, including macular degeneration and glaucoma. Additionally, as this form of photography provides a unique view of your vasculature without the need for a biopsy, making it valuable monitoring tool for patients with diabetes, high blood pressure, or cholesterol.
Optical Coherence Tomography (OCT)
Used to describe a series of scans which are taken to visualise and determine the thickness of a structure in your eye, OCT is currently the most advanced method of imaging the eye. Similar to an ultrasound, except it uses light instead, the result is a 3D model with an incredible level of detail. Non-invasive, fast, and comfortable to perform, it can effectively detect, diagnose, and monitor various eye conditions and diseases including glaucoma and retinal diseases.
Corneal Topography
Corneal topography precisely maps the cornea. Creating a 3D profile of the corneal shape, it can accurately show all of the contours and unique topographical features of the eye at an incredible level of detail. Essential in the fitting of soft and hard contact lenses, it is especially useful for high astigmatism, keratoconus, post graft/corneal transplant and orthokeratology. OCT is also very useful for diagnosing and managing complex eye diseases such as keratoconus as well as allowing optometrists to manage and treat severe dry eye disease.
Wavefront Aberrometry
Wavefront aberrometry revolutionises the management of hyperopia, myopia, astigmatism, keratoconus, and contact lens design. Measuring many rays of light to create a collective wavefront, this wavefront can then be broken down mathematically into a series of known orders of shape into what is known as a ‘Zernike polynomial’1. This technology allows for the correction of all aberrations, creating a perfect optical system for a singular point of focus.
