Have you ever been referred to an eye specialist’s office for additional testing? One of these tests may have been an OCT. Have you ever wondered why your eye doctor has recommended this test and what it is for?
OCT, or Ocular Coherence Tomography, is a non-invasive and painless diagnostic instrument used to create an image of your retina and optic nerve. While similar to a CT scan in the way that it produces images of your internal body structures, the OCT uses light—instead of radiation—to rapidly scan the layers of your retina and create a 3D cross-section of the area. What that scan reveals about the condition of your retina can be interpreted by an Optometrist or Ophthalmologist.
