Optical Coherence Tomography (OCT) with our Brighton, Trenton, and Bellville Optometrists

Optical coherence tomography (OCT) is a test that uses light to take a picture of your retina. At Dr. Bruce Coward & Associates, our optometrists in Brighton, Trenton, and Belleville, use this to test for a variety of conditions. The test is non-invasive and provides the eye doctor cross-sectional images of your retina. The retina is an inner eye structure that serves the role similar to film in a camera; the eye creates a visual image on the retina, and the retina translates that image to the brain to create the perception of that image.

What happens during OCT?

OCT is a painless test that takes about 10 minutes. It may require for your doctor to dilate your eye to make your pupil bigger and get a better picture of the retina. During the test, patients are required to sit in front of the OCT machine and keep their head motionless. Patients look into a viewfinder and a camera in the OCT machine scans the eyes. Afterwards, your eyes may be sensitive to light if dilation was needed.

What Conditions can OCT diagnose?

Doctors use OCT to evaluate retinal conditions and optic nerve disorders. OCT is useful in diagnosing several types of eye conditions:

  • Macular degeneration
  • Macular disorders like a macular hole, pucker or edema
  • Glaucoma
  • Diabetic retinopathy and other types or retinopathy

Since OCT uses light waves to scan the eyes, it cannot be used to detect conditions like cataracts that prevent or impede light from passing through the eye.
