History of Optical Coherence Tomography Use In Eye Care

When you have vision concerns or it is time for your yearly eye exam, Optical Coherence Tomography, or OCT for short, is one of the top and most widely used ways to take an image of the human eye. This incredible piece of technology is a key factor for early detection of, and correctly diagnosing, many different vision impairments. Thanks to OCT, a variety of vision disorders and diseases can be detected early on, allowing more people the opportunity to restore and preserve their eyesight. Let’s take a look at Optical Coherence Tomography and it’s historic development for vision care.

An Overview of Historic Optical Coherence Tomography

Simply put, Optical Coherence Tomography is widely used due to its ability to take high resolution images of the eye through the reflection of light.

Early on in optometry, eye doctors were only able to take a cross section image of the eye. but in 1990 German Professor Adolf Friedrich Fercher was the first to create a 2-dimensional image of the eye, which laid all the groundwork for the development of OCT. Once he was able to complete his scan, it was sent to his colleagues in Massachusetts to take his initial imaging and create the final 2D image which was proof of the huge potential of this technology and its ability to detect abnormalities of the tissues within the eye. By 1996, this technology was on the market commercially for purchase by optometry clinics.

Unbeknownst to them at the time, this breakthrough would contribute greatly to the better understanding of many diseases across multiple health disciplines, including cardiology, cancer, and neurological diseases such as MS and and Alzheimers.

Medical professionals have been using this type of technology to create other types of diagnostic images such as X-rays, MRI’s and CT Scans, but the benefit of an OCT scan is that the light is reflected a very short distance, allowing for very high quality images.

OCT is used to detect many vision conditions of the retina such as:

  • Age Related Macular degeneration
  • Macular hole
  • Macular pucker
  • Macular edema
  • Diabetic retinopathy
  • Central serous retinopathy
  • Glaucoma
  • Vitreous traction
  • Changes to the optic nerve
