What if your eye doctor was able to not only view your eye’s surface during an eye scan but examine all of the layers of your eye and examine your retina with full color 3D digital images?

With optical coherence tomography (OCT), we can!

OCT has revolutionized retinal imaging by making it possible for optometrists to detect the first stages of glaucoma, diabetes and macular degeneration early enough to prevent or minimize vision loss.

How Does Optical Coherence Tomography Work?

Optical coherence tomography operates like an ultrasound, except that it uses light waves instead of sound waves to take cross-sectional images of the retina, at the back of the eye.

The resulting images show all the layers of the retina in full color and 3 dimensional detail. This can reveal much more than traditional retinal photography, which captures only the top layer of the retina. These deeper, more detailed digital images can help your eye doctor in Concord diagnose many potentially serious eye problems early on, when treatment is typically more effective.


What Conditions Does Optical Coherence Tomography Detect?

OCT scanning can be used to detect many eye conditions. Here are the most common:

  • Macular degeneration
  • Glaucoma
  • Diabetic retinopathy
  • Macular edema
  • Retinal bleeding or occlusions
  • Retinal tear
  • Retinal detachment
  • Retinal/macular cysts or holes

What to Expect from an Optical Tomography Scan

Optical coherence tomography is non-invasive: it’s performed without making contact with the eye or retina. It feels like having an ultrasound, is comfortable and the procedure lasts just a few minutes. In some cases, your eye doctor may want to dilate your eyes first by putting special eye drops in your eyes in order to see your retina more clearly. The effects of dilation wear off in a few hours.

Who Should Get an Optical Coherence Tomography Scan?

Your optometrist will recommend imaging to check the health of your eyes, particularly if you are over 50, have diabetes or hypertension, or have a personal or family history of eye problems. Your Concord eye doctor may encourage an OCT scan rather than standard retinal imaging to get a more in-depth view of your retina to detect and treat problems before they permanently damage your vision.
