What you need to know about OCT Test

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section scans (pictures) of your retina. 

With OCT, your optometrist can see each of the retina’s distinctive layers. This allows us to map and measure their thickness. These measurements help with both diagnosis and disease monitoring. They also provide treatment guidance for diseases of the retina including age related macular degeneration and glaucoma. OCT can also be used to obtain detail images of the anterior structures of the eye. 

OCT is useful in diagnosing/monitoring a wide range of eye conditions, including: 

  • Glaucoma 

  • Age related macular degeneration 

  • Macular disease (oedema/hole/epiretinal membranes) 

  • Diabetic retinopathy 

  • Central serous retinopathy 

  • Drusen 

  • Retinal detachment/retinoschisis 

  • Disorders of the optic nerve (oedema/drusen) 

  • Vitreous traction 

  • Retinal lesions 

At Martin and Lobb OCT images are taken onsite using a Cirrus HD-OCT.  The test is non-invasive and painless; you simply rest your head against the forehead/chin rest and look at a target inside the machine while your scans are taken.  

There is an additional cost of $95 ($47.50 per eye) to have OCT images taken.  Your optometrist will advise you if this is recommended for your eyes.
