Optical coherence tomography (OCT) is a noninvasive imaging technology used to obtain high resolution cross-sectional images of the retina. OCT is similar to ultrasound testing, except that imaging is performed by measuring light rather than sound. OCT measures the retinal nerve fiber layer thickness in glaucoma and other diseases of the optic nerve.

  • The advanced OCT technology provides detailed images of the retina not observable by any other means.
  • This non-contact, non-invasive tool can lead to earlier confirmation of damage so doctors can provide earlier treatment.
  • The scanner produces high-resolution (10 times greater resolution than any other technique available), cross-sectional images of the retina.
  • This equipment does not require injections or exposure to painful, high-intensity light, which means improved patient comfort and safety.
