Optical Coherence Tomography (OCT) is a standardised method of imaging cross-sections of the retina in a non-invasive procedure. It is one of the most widely used tools for detecting diseases and conditions affecting the retina and surroundings.

The Optometrist will ask you to situate your chin on the machine while a lens thoroughly scans each eye. You may require eye drops before the procedure to allow the pupils to remain dilated.

OCT works similarly to an ultrasound scan but uses light instead. It allows us to see the thickness of the retina and find out if you have any underlying conditions or diseases such as glaucoma, diabetes, swelling or other retina complications.
