OCT is Optical Coherence Tomography.

This is the next generation in imaging the internal structures of the eye.

The OCT is a special scanner that creates a sort of optical ultrasound three dimensional image of the inside of the eye.

The unique way the image is formed means that we can see below the surface of the retina and view the microscopic layers beneath.

This is of profound importance in determining the precise diagnosis of visual problems and in helping us guide patients on the treatment options possible.

Typical conditions requiring OCT:

  • Macular degeneration or drusen
  • Macular hole or epiretinal membrane
  • At risk glaucoma
  • Vitreous Floaters
  • Diabetic retinopathy
  • Optic nerve disease

Taking a ‘baseline’ OCT image is helpful for future comparison and detecting early signs of eye disease.

We recommend all patients over 50 have a baseline  OCT image taken, and then repeated according to clinical need.
