Ocular Coherence Tomography (OCT)

What is it?
This is a scanning technique used to capture detailed images of the cornea at the front of the eye and the retina at the back of the eye. It captures micrometer-resolution, 3-D images from different tissue layers within the eye and can be used to detect subtle changes of structures such as the optic nerve and macula before these would be visible with traditional imaging methods. OCT scanning is a useful tool to monitor the progression of conditions such as macular degeneration and glaucoma.


How is it done?
This is a non-invasive test performed with your chin on the instrument chin rest and fixating on a green target in the instrument lens. Several scans can be taken within a few minutes usually without pupil dilation.
