Optical Coherence Tomography (OCT)
Optical Coherence Tomography, or OCT, is an advanced technology used for retinal imaging and analysis. This technology provides highly detailed images of the retina as well as the optic nerve. These cross-sectional images are viewable in 2D and 3D, allowing for topographical mapping of the eye including retinal layer and nerve fiber layer thickness.
The accuracy of the OCT means that repeatability of measurement is very high and serial scans are very sensitive to changes in the eye that may signify the very earliest signs of eye disease such as glaucoma, macular degeneration, etc.
At iSight, we recommend a routine OCT scan if you have migh myopia (more than -6.00 D), or if you have any family history of eye diseases, such as glaucoma, or macular degeneration.
Remember, the earlier we detect any signs of abnormality, and the earlier we implement treatments, the better the clinical outcome of preventing vision loss.
