Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina, the light-sensitive tissue lining the back of the eye. With OCT, each of the retina’s distinctive layers can be seen, allowing your optometrist to map and measure their thickness. These measurements help with early detection, diagnosis and treatment guidance for retinal diseases and conditions, including age-related macular degeneration and diabetic eye disease, among others. In addition, OCT is often used to evaluate disorders of the optic nerve. The optic nerve is made up of many nerve fibers and sends signals from your retina to your brain, where these signals are interpreted as the images you see. The OCT exam is helpful in determining changes to the fibers of the optic nerve, such as those caused by glaucoma.

Digital Retinal Photography (DRP) is a cutting-edge technology which enables eye doctors to discern even the most subtle changes in your retina. This technology helps optometrists with the early detection of eye disease and in monitoring the progression of a disease and when or if to consider a referral to a sub-specialist.
