What is optical coherence tomography (OCT)? It is an imaging technology that lets your eye doctor see the back of your eye - without dilation - to discover vision-stealing diseases like glaucoma, macular degeneration and diabetic eye disease.

In a series of videos highlighting patients, doctors and scientists, learn how OCT moved from the lab to quietly revolutionizing eye care around the world.

OCT - the eye: a window to blood and brain diseases

With OCT, devastating diseases like Alzheimer's and Parkinson's can be detected earlier than ever before  enlarging the window of opportunity for future treatments.


OCT - bringing the eye doctor to you

New technologies like OCT could one day soon let you take an eye exam while sitting in a department store or with your smartphone.


OCT - a better view during surgery

To better guide surgeon's eyes, technologies like OCT are being brought into the operating room to help a surgeon decide where to operate, and just as importantly, when to stop.


OCT - staying ahead of preemie vision disease

Pioneering doctors and engineers are working to adapt existing medical technologies like OCT for use in neonatal intensive care units (NICUs). The result? An ability to see in the tiniest of eyes, monitor their fragile development and preserve vision for a long, healthy life.


OCT - government-funded discovery

Government funding around the world exists to support the first steps of a technology's development. OCT owes its success in part to taxpayers willing to invest in biomedical research.


OCT - detecting a stealthy disease - glaucoma

Glaucoma is a stealthy, vision-stealing disease that was very hard for doctors to detect  -  before OCT. But with this new technology, doctors can diagnose the disease and offer treatment even before a patient notices any vision loss.


OCT - taking the guesswork out of diabetic eye disease

With OCT, doctors no longer have to guess if the vision of a person with diabetes is getting better or worse, and patients can see for themselves images that show how effective they have been in managing their disease.


OCT - catching macular degeneration before vision loss

Thanks to the invention of OCT, doctors can catch age-related macular degeneration (AMD) before vision is lost. And with the aid of new drugs, AMD can be stopped in its tracks.
