What is OCT? Ocular Coherence Tomography is an advanced eye scan for people of all ages.
Similar to ultrasound, OCT uses light rather than sound waves to illustrate the different layers
that make up the back of the eye.
Optical coherence tomography (OCT) was developed in 1991 and was commercially introduced to ophthalmology in 1996.1 2 First-generation OCT instruments provided a 2D cross-sectional view of the human retina at a microscopic resolution (10 μm) in vivo. Because of its noncontact and noninvasive imaging capabilities, OCT quickly became an indispensable clinical tool for assessing retinal abnormalities, including the leading causes of blindness: age-related macular degeneration, diabetic retinopathy, and glaucoma.
This particular 3D OCT unit captures a digital photograph of the back of the eye at the same
time as scanning it. This can then be cross referenced across any areas of concern.
Never before has it been easier to find out the exact state and location of a particular eye
condition. Your optometrist can review the images on a PC screen and pin point areas of
concern by digitally peeling the layers back to find anything that may require further investigation.
