Artificial intelligence begins diagnosing patients in Eastern Iowa

First of its kind device created by IDx to detect diabetic retinopathy

CORALVILLE — The University of Iowa Hospitals and Clinics has become the first to employ new technology — developed by a company rooted in the university’s research engine — that uses artificial intelligence to diagnose an eye disease.

On June 12, the Diabetes and Endocrinology Center at UI Health Care-Iowa River Landing in Coralville began using technology developed by IDx, the Coralville-based medical diagnostics company.

The device, which received approval from U.S. Food and Drug Administration in April, was developed to diagnose diabetic retinopathy, a diabetes complication that can cause blindness.

Called IDx-DR, the device uses software and a retinal camera to take images of a patient’s retina. From there, the AI analyzes the patient’s images “the same way I do as a clinician” to determine if the patient has the condition, said Dr. Michael Abramoff, president and director of IDx and UI Health Care ophthalmologist.

“It looks for different lesions like hemorrhages, microaneurysms, many other abnormalities you get from diabetes in the retina if it’s abnormal, which is what I do when I look for a patient,” he said.

“Then it analyzes the combination of all these different features and it gives you a clinical decision by itself.”

The Diabetes and Endocrinology Center has approximately 7,200 patient visits per year, according to UI officials in a news release on the device.

Diabetic retinopathy can affect anyone with Type 1 or Type 2 diabetes, and is one of the leading causes of blindness in the United States, according to the federal Centers for Disease Control and Prevention.

Early detection is key, Abramoff said. However, as diabetic retinopathy lacks early symptoms, individuals must undergo regular retinal exams to spot the condition.

Abramoff hopes his device can make that process easier by providing accessibility to this exam outside of an eye specialist. IDx-DR is used by provider staff during routine visits and can provide results within moments.

Then, if IDx-DR detects more than mild diabetic retinopathy, the patient is referred for follow-up examinations and treatment with an eye specialist.

According to his clinical trials with 900 patients before the FDA approval, Abramoff said the device had an 87 percent sensitivity to detecting the disease in all types of patients.

Any procedures or treatments to be conducted by an autonomous AI are far off, but Abramoff said he is hopeful the technology will expand to more clinics and other health care settings.

This, he believes, could be the future of detecting and diagnosing other diseases.

UI Health Care plans to expand use of this device across the system, university officials said in the news release.

“I see a great future,” Abramoff said.

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke...

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that th...

New ATM's: withdraw money with veins in your finger

New cash machines: withdraw money with veins in your finger Cash machine technology that reads the pattern of finger veins is already available in Japan and Poland   By Telegraph Reporters 6:59PM BST 15 May 2014 Cash machines could soon be installed with devices that identify customers by reading the veins in their fingers. The technology is already being rolled out in Poland, where 1,730 cash machines will this year be installed with readers, negating the need for a debit card and Pin. Developed by Hitachi, the Japanese electronics firm, the machines read the patterns of the veins just below the surface of the skin on your finger using infra-red sensors. The light is partially absorbed by haemoglobin in the veins to capture a unique finger vein pattern profile, which is matched to a profile. The technology is used by Japanese banks and also in Turkey, offering “groundbreaking levels of accuracy and speed of authentication”, Hitachi said, which in t...
