Keratoconus and corneal topography
Keratoconus is a condition whereby the cornea (the front surface of the eye) thins and warps into a "cone" shape leading to visual distortion. Using a specialised corneal topographer we can map out and monitor the progression of this eye dystrophy and use the parameters it provides to design a specialised contact lens that will help to minimise the visual distortions the patient perceives.
Anterior eye photography
Any unusual features of the front surface of the eye can be captured and stored using this technique. It is a vital tool in monitoring progression of certain eye problems. Our OCT 3D imaging device can also measure corneal thickness and dimensions, and allow us to view the anterior irido-corneal angle, which is useful in assessing for closed angle glaucoma.
Optical coherence tomography (OCT) is a non-invasive, non-contact, transpupillary imaging technique able to produce high-resolution images detailing the 3D structure of the eye, from the anterior segment to the posterior pole. OCT uses light waves to take cross-section pictures of the retina. With OCT, your optometrist can view all of the retina’s distinctive layers and they can map and measure the thickness of the retinal layers. Incredible detail of the retinal vasculature can be observed with the digital camera setting. Retinal diseases including age-related macular degeneration (AMD) and diabetic eye disease can be easily detected using this technology.
