Optical coherence tomography (OCT) is a non-invasive diagnostic imaging test similar to a computed tomography (CT) scan that allows your retina specialist to clearly see the retina and carefully map and measure the thickness of each of its layers. One of the most common tests we perform at Texas Retina Associates, OCT is used to help diagnose and monitor a number of retinal diseases and conditions, including age-related macular degeneration (AMD), macular edema, diabetic retinopathy, macular hole, macular pucker, and central serous retinopathy.
How Does it Work?
OCT uses light waves to take high-resolution, cross-section pictures of your retina. Your physician may put dilating drops in your eyes before performing the OCT to make it easier to see the retina. During the test, you will sit in front of the OCT scanner and rest your head on a support to keep it still. You will then look into the lens of the machine, and it will scan your eyes without touching them. The test only takes a few minutes.
OCT testing is available at all of our Texas Retina Associates offices.
