OCT - Optical Coherence Tomography - is an advanced eye scan for people of all ages and is part of the comprehensive eye examination. OCT uses light to photograph the different layers that make up the structures at the front and back of the eye, creating a 3D image of the eye.
The OCT allows both instant and early diagnosis of a number of common ocular conditions. The scan is non-invasive, painless, simple and quick. Regular OCT at every eye examination gives the Optometrists an ongoing record of the health and condition of your eyes.
Common conditions identified through regular OCT screening include:
Age-related Macular Degeneration
Age-related macular degeneration (AMD) is the leading cause of blindness in the UK. It causes gradual deterioration of the macular - the central portion of your retina which enables detailed vision. OCT can help to identify the earliest signs of AMD and monitor it's progress over time.
Diabetic Retinopathy is one of the leading causes of blindness in people of working age in the UK. OCT examination helps enable early detection of diabetic Retinopathy, allowing early referral and management which can improve the success rate of treatment.
Glaucoma is a condition which causes damage to the optic nerve, and causes gradual loss in peripheral vision. As early stages of glaucoma do not cause symptoms, regular eye examinations are essential to pick up glaucoma in its early stages. OCT examinations can measure numerous features at the back of the eye to facilitate early diagnosis of glaucoma.
