title: Imaging in Diabetic Retinopathy: A Review of Current and Future Techniques.
abstract: BACKGROUND
  Diabetic eye disease is the most common cause of blindness worldwide in the population under 65 years of age. The prevalence of sight-threatening diabetic eye disease continues to rise rapidly, resulting in an increasing burden on health systems worldwide. This highlights the need to develop new tools to help in the screening, diagnosis and management of diabetic eye disease.
  
  
  OBJECTIVE
  This review aims to provide a brief overview of the current standard in care for diabetic eye disease, before providing an up to date overview of newer imaging modalities, with potential application in the management of diabetic eye care.
  
  
  METHODS
  A literature search for the terms "enhanced depth imaging OCT", "swept source OCT", "retinal oximetry", "OCT angiography", "fundus autofluorescence" with the term "diabetes" was performed using the pubmed and google scholar databases. Only articles published within the last two years were selected for use in this article.
  
  
  CONCLUSIONS
  There has been a rapid increase in the available imaging techniques used to manage diabetic eye disease. To date there has been variable use of these next generation imaging techniques. A greater understanding of how phenotypic findings link to the risk of sight loss is required before there is more widespread adoption by mainstream diabetic eye services.
