A British company is exploitation Microsoft’s cloud technology to help eyecare specialists diagnose major diseases much earlier.
Visulytix has created a program called Pegasus that sends the 2D and 3D eye scans that people have had taken in practice stores, screening centres and doctors’ surgeries to the Azure cloud, and uses artificial intelligence to spot early signs of eye disease, diabetic retinopathy and macular degeneration in seconds.
The health care professional conducting the scan then looks at the regions of the image the AI has highlighted as possibly showing signs of those diseases, and decides whether to refer the patient to see a specialist.
Visulytix believes that exploitation Pegasus in practice and screening would improve early detection of these conditions, which can lead to sightlessness, by reducing false positive and false negative diagnoses. It would besides save the UK economy billions of pounds in associated health care reimbursement, the company added.
Jay Lakhani, Chief Executive of Visulytix, aforesaid the key to preventing sightlessness was catching conditions early, and AI is portion health care professionals do that.
“The problem with galore blazing eye diseases so much as eye disease and diabetic retinopathy is that they can develop slowly, with patients often unaware they have a condition,” he aforesaid. “There’s no abrupt impact on your vision, which means people may not notice them for quite a long time, piece quietly, losing sight. The diseases can not yet be quite advanced by the time patients present to eye employment, at which point the conditions could be irreversible.”
“We see our solution as ‘decision support’ – AI and doctor working together. What Pegasus does is upskill the user, so they can operate with a specialist’s level of accuracy. AI-provided decision support inevitably to be used to counter the fact that there simply aren’t enough ophthalmologists. Pegasus can fill that void by upskilling non-specialists so they make better referrals, leading to better use of health care resources. at the same time , by reducing false negatives, Pegasus can help to identify patients who would have otherwise gone blind in time thereby reducing the pressure on the NHS, as well as the patient’s family and friends.”
Glaucoma is one of the most common ophthalmic conditions. According to the BMJ, the management of patients with eye disease constitutes a major part of ophthalmologists’ employment, accounting for 23 per cent of all follow-up attendances to specialists in the UK. There are more than one million eye disease-related NHS visits per year.
The speed at which Pegasus can work, with results in seconds, is helped by the service being hosted on Azure. Microsoft’s cloud platform is stable, secure and flexible, so it can cope with abrupt spikes in demand.
“In certain emerging markets, so much as environment of Asia, not everybody has a good net connection
,” Lakhani added. “We see that our customers take a lot of images in low property areas, go back to an area of high property and transfer all those images at the same time. This results in some users transfering thousands of images at a time because they want to do the analysis of these images in one go. Because of that, we see a lot of random spikes in web traffic but Azure can handle it. I think it’s great.”
Visulytix is about to start a pilot in India that will see the company use Pegasus as they give eye exams to tens of thousands of people in remote villages. With polygenic disorder reaching epidemic levels in the country, according to The International Agency for the bar of sightlessness, cases of diabetic retinopathy are rising. Of the estimated 425 million people diagnosed with polygenic disorder globally, 82 million are in India. “We can decidedly add value in environment of India where people have little to no access to eye screening,” Lakhani aforesaid. “These are areas where we can make the biggest impact. People in those villages would not receive eye screening without help from AI employment so much as Pegasus.”
The NHS recommends that most people should get their opinion tested every two years, but this should be more frequent if you have polygenic disorder, are aged 40 or over and have a family history of eye disease, or aged over 70.
