This latest technology has revolutionised the examination of the most important features of the retina, namely the optic nerve (structure that carries information back to the brain), and macula (central part of the retina).
Scans captured using the OCT provide invaluable information for both the early detection, and diagnosis of various eye conditions that may have otherwise been missed until a later stage in the disease process. By investigating deeper layers of the retina in a 3-dimensional image, the device looks beneath the surface, much like an ultrasound scan. Images can be acquired within a few seconds, in a simple and comfortable manner, with the patient experiencing light flashes during the measurement.
Our optometrists have undertaken vigorous training to analyse scans precisely, working alongside local ophthalmologists to inform decision-making and referrals for further investigation. OCT scans can be carried out for patients of all ages, but we recommend in particular, the following groups:
Individuals aged over 40 years, as these persons are more at risk of conditions such as glaucoma and macular degeneration
Those with a family history of age-related macular degeneration, glaucoma, or diabetes
Where results of previous tests in the eye examination warrant more frequent monitoring of the retina (e.g. a mole at the back of the eye)
As a baseline measurement for any age group, so that there is a reference for us to compare against if any future symptoms or conditions arise
The prognosis for conditions such as glaucoma, diabetic macular oedema and macular degeneration is better when detected and treated at an early stage to prevent further loss of vision.
