OCT is an imaging technique that can be used to detect and diagnose many eye diseases.

OCT uses infrared light rays to measure the micro-anatomy of eye structures. Snapshots are taken at different depths and the lines then combine to create a cross-sectional image. The 3D imaging allows improved diagnosis of pathology and changes over time by providing vivid illustrations of retinal and optic nerve structures.

OCT is used for diagnosis and follow-up of the following conditions:

  • Macular degeneration (OCT is required urgently for this condition)
  • Glaucoma
  • Retinopathy in all diabetics
  • Post-operative cataract surgery
  • Optic nerve analysis in compression injuries and other pathologies, including Multiple Sclerosis (MS)
  • Other retinal abnormalities
