Optical Coherence Tomography

ENLARGE TEXT

Optical Coherence Tomography, or OCT, is a laser-based, noncontact, noninvasive imaging technique that is capable of obtaining high-resolution images of the retina and its components.

 

OCT is analogous to ultrasound imaging except that light rather than sound waves is used, resulting in a much higher resolution of approximately 10µm in the retina. OCT provides direct, real-time, cross-sectional images of retinal tissue layers, allowing improved resolution and diagnostic capabilities of a variety of eye diseases.

Optical Coherence Tomography

  • NFL: Nerve Fiber Layer
  • RPE: Retinal Pigment Epithelium
  • ILM: Inner Limiting Membrane
  • CC: Choriocapillaris

  • GCL: Ganglion Cell Layer
  • IPL: Inner Plexiform Layer
  • IS/IOS: Inner & Outer Photoreceptor Segment Junction
  • OPL: Outer Plexiform LayerLorem Ipsum

OCT has the capability of measuring the retinal nerve fiber layer thickness in glaucoma, making it possible to detect glaucoma damage at an earlier stage than was previously possible. In addition, objective measurements can be monitored, aiding in better control of disease progression.
