Optical coherence tomography

Cross sectional imaging that shows the layers beneath the surface.

OCT uses light waves to build a cross section of the eye at microscopic resolution, the way an ultrasound builds a cross section with sound. Where topography maps the surface, OCT shows what sits underneath it. That makes it the test that distinguishes a stable finding from a progressing one, because thickness can be measured today and compared against the same measurement next year.

What it finds

  • Corneal thickness and layer structure
  • Optic nerve fibre layer thinning in glaucoma
  • Macular swelling and fluid
  • Scleral lens vault and clearance
  • Progression tracking over time
