AI Tool Detects Diabetes-Related Eye Condition Without Human Interpretation - AI Trends

#artificialintelligence

Last year, IDx-DR became the first-ever so-called "autonomous AI" system cleared by the FDA to provide a screening decision without the oversight of a doctor. Since then, IDx Technologies, the company behind the product, has begun to roll out this tool designed to detect diabetic retinopathy. Over 30 million people are living with diabetes in the US alone. "The disease itself is bad," said Michael Abramoff, a University of Iowa ophthalmologist and computer scientist, "but the complications make it even worse." One of those complications is diabetic retinopathy, the leading cause of blindness in American adults.


Automated Process Incorporating Machine Learning Segmentation and Correlation of Oral Diseases with Systemic Health

arXiv.org Machine Learning

Imaging fluorescent disease biomarkers in tissues and skin is a non-invasive method to screen for health conditions. We report an automated process that combines intraoral fluorescent porphyrin biomarker imaging, clinical examinations and machine learning for correlation of systemic health conditions with periodontal disease. 1215 intraoral fluorescent images, from 284 consenting adults aged 18-90, were analyzed using a machine learning classifier that can segment periodontal inflammation. The classifier achieved an AUC of 0.677 with precision and recall of 0.271 and 0.429, respectively, indicating a learned association between disease signatures in collected images. Periodontal diseases were more prevalent among males (p=0.0012) and older subjects (p=0.0224) in the screened population. Physicians independently examined the collected images, assigning localized modified gingival indices (MGIs). MGIs and periodontal disease were then cross-correlated with responses to a medical history questionnaire, blood pressure and body mass index measurements, and optic nerve, tympanic membrane, neurological, and cardiac rhythm imaging examinations. Gingivitis and early periodontal disease were associated with subjects diagnosed with optic nerve abnormalities (p <0.0001) in their retinal scans. We also report significant co-occurrences of periodontal disease in subjects reporting swollen joints (p=0.0422) and a family history of eye disease (p=0.0337). These results indicate cross-correlation of poor periodontal health with systemic health outcomes and stress the importance of oral health screenings at the primary care level. Our screening process and analysis method, using images and machine learning, can be generalized for automated diagnoses and systemic health screenings for other diseases.



FDA Approves Artificial Intelligence-Based Device to Detect Certain Diabetes-Related Eye Problems

#artificialintelligence

The FDA has permitted marketing of IDx-DR (IDx LLC)--the first medical device to use artificial intelligence to detect greater than a mild level of the eye disease diabetic retinopathy in adults who have diabetes. Diabetic retinopathy occurs when high levels of blood sugar lead to damage in the blood vessels of the retina, the light-sensitive tissue in the back of the eye. Diabetic retinopathy is the most common cause of vision loss among the more than 30 million Americans living with diabetes and the leading cause of vision impairment and blindness among working-age adults. "Early detection of retinopathy is an important part of managing care for the millions of people with diabetes, yet many patients with diabetes are not adequately screened for diabetic retinopathy since about 50% of them do not see their eye doctor on a yearly basis," said Malvina Eydelman, MD, Director of the Division of Ophthalmic, and Ear, Nose, and Throat Devices at the FDA's Center for Devices and Radiological Health. "Today's decision permits the marketing of a novel artificial intelligence technology that can be used in a primary care doctor's office.
