OCT: Interpreting the image

Optical coherence tomography (OCT) is used increasingly in optometric practice to identify retinal pathology, to improve referral accuracy and to monitor for progression of disease. It is vital that the optometrist understands the image in front of them and knows how to describe any abnormality to another professional. Brought to you with Heidelberg Engineering Ltd, this video shows a systematic approach to interpreting the OCT, use of terminology and when to refer. We use case examples and explore what happens in the hospital setting.
