OCT – or Optical Coherence Tomography – utilizes light waves to capture high-resolution images of eye tissue. It provides a cross-section view of the retina, allowing for non-invasive observation of each distinct layer of the retina. This method aids in the diagnosis of macular degeneration, diabetic eye disease, and numerous other retinal conditions. It can also measure the fibers of the optic nerve aiding in the diagnosis of glaucoma.
OCT allows us to see detail in the eye tissues that would normally only be observable under a microscope – but does not do any damage to the tissue. This technology has allowed for earlier detection and a better understanding of eye disease, which can both lead to better treatments and visual outcomes.
The testing is quick, taking less than 10 minutes from start to finish, does not require the eye to be dilated, and provides immediate results. It is also done to track the eye for changes over time, further enhancing the value and necessity of the technology.
