7. Pearse Keane Q&A: how open access AI is bringing ophthalmology into focus
  
  Explore Medical Device Network Oct 16 2019 Ophthalmology
  
  Since 2016, Moorfields Eye Hospital in London has been working with DeepMind, one of the worlds leading artificial intelligence companies. Through the partnership, researchers hope to use over one million anonymised retinal images to train artificial intelligence (AI) in the automated diagnosis of optical coherence tomography (OCT) images. OCT images are extremely complex and can take clinicians a long time to analyse, which can impact how quickly patients can receive ...

  Purpose To compare routine clinical examination with optical coherence tomography angiography (OCTA) for the assessment of limbal conjunctival ischemia following a chemical burn. Setting Validity analysis Methods We assessed ten participants (15 eyes) with an acute chemical injury. Clinical photographs were used to determine the extent of any limbal conjunctival epithelial defect and ischemia. These were compared with the extent of limbal ischemia identified on OCTA images of the ocular ...

13. Predicting optical coherence tomography-derived diabetic macular edema grades from fundus photographs using deep learning
  
  Explore arxiv.org Oct 31 2018 Ophthalmology
  
  Diabetic eye disease is one of the fastest growing causes of preventable blindness. With the advent of anti-VEGF (vascular endothelial growth factor) therapies, it has become increasingly important to detect center-involved diabetic macular edema. However, center-involved diabetic macular edema is diagnosed using optical coherence tomography (OCT), which is not generally available at screening sites because of cost and workflow constraints. Instead, screening programs rely on the detection of hard exudates ...

  The volume and complexity of diagnostic imaging is increasing at a pace faster than the availability of human expertise to interpret it. Artificial intelligence has shown great promise in classifying two-dimensional photographs of some common diseases and typically relies on databases of millions of annotated images. Until now, the challenge of reaching the performance of expert clinicians in a real-world clinical pathway with three-dimensional diagnostic scans has remained unsolved. Here ...

  When Pearse Keane started using optical coherence tomography (OCT) scanners to peer to the back of a person's eye in Los Angeles a decade ago, the machines were relatively crude. "The devices were lower resolution, they had much slower image acquisition speeds," says Keane, a consultant ophthalmic surgeon at Moorfields Eye Hospital and researcher at University College, London. From 2007, Keane spent two years studying scans from OCT machines ...
