Company profile
researched Aug 2026IDx, later known as Digital Diagnostics, is a Coralville, Iowa-based artificial intelligence diagnostics company founded in 2010 by a team of clinician scientists. It develops clinically-aligned autonomous AI systems that detect disease in medical images, with the stated aim of enabling specialty-level diagnostic assessment in primary care settings and thereby broadening patient access to disease detection.
The company's first product, IDx-DR (later renamed LumineticsCore), is an AI-based diagnostic system intended for use by health care providers to automatically detect more than mild diabetic retinopathy in adults aged 22 or older who have been diagnosed with diabetes but not previously diagnosed with diabetic retinopathy. It is indicated for use with the Topcon NW400 robotic fundus camera. In April 2018 the system received FDA clearance, described as the first time the FDA cleared an autonomous AI diagnostic system that does not require a physician to interpret the images or results, allowing providers outside eye care to test for the condition during routine office visits.
Beyond diabetic retinopathy, IDx has said it is developing additional autonomous AI diagnostic platforms for macular degeneration, glaucoma, Alzheimer's disease, cardiovascular disease and stroke risk, as well as conditions outside the eye, and has explored partnerships with other autonomous AI companies using an ethics-based approach to algorithm development.
Founding story
IDx was founded in 2010 by a team of clinician scientists led by Dr. Michael Abramoff, who served as founder and CEO. The company operated in stealth mode for its first eight years before receiving public attention in April 2018 upon FDA clearance of its diabetic retinopathy detection system.
Business model
IDx develops and commercializes FDA-cleared autonomous AI diagnostic systems used by health care providers at the point of care, deployed together with compatible retinal imaging hardware.
Traction
The company more than doubled its staff during 2018, from 23 to 51 employees, obtained FDA clearance and began clinical use of its system in 2018, and expanded distribution via CarePortMD in November 2019.
Latest developments
In June 2020 the company filed paperwork indicating it had raised $12.5 million. It has also been developing further autonomous AI diagnostic platforms for macular degeneration, glaucoma and diseases outside the eye, and exploring partnerships with other autonomous AI companies.
▸Full profile — market position, technology, go-to-market, geography, history
Market position
IDx-DR was described as the first and only AI system cleared by the FDA to detect diabetic retinopathy without requiring a clinician to interpret the image or results, and the company's September 2018 Series A was reported as the largest investment round raised by an Iowa company in 2018.
Technology
The core technology is autonomous artificial intelligence that analyzes medical images and produces a diagnostic assessment without a clinician interpreting the image or the result. IDx-DR/LumineticsCore is designed for use with the Topcon NW400 robotic fundus camera. Founder Michael Abramoff was awarded U.S. Patent No. 9,924,867 covering systems that automatically measure cardiovascular health from the retina (March 2018) and U.S. Patent No. 10,140,699 covering AI systems, medical and non-medical, that use sample training data to detect objects in images (November 2018).
Go-to-market
Deployment through clinical care sites, beginning with the Diabetes and Endocrinology Center at University of Iowa Health Care, and through partnerships, including an exclusive AI partnership with device manufacturer Topcon and a 2019 launch within CarePortMD.
Health care providers, including primary care and other clinicians not normally involved in eye care, who treat adults with diabetes; care settings such as endocrinology and diabetes centers and rural practices.
Geography
Headquartered in Coralville, Iowa, United States, with early clinical deployment in Iowa.
History
After eight years of stealth-mode development following its 2010 founding, IDx received a FDA "Breakthrough Device" designation for IDx-DR in February 2018 and FDA clearance in April 2018. The product launched in patient care at the Diabetes and Endocrinology Center at University of Iowa Health Care in June 2018, and the pivotal trial supporting clearance was published in Nature Digital Medicine in August 2018. The company closed a $33 million Series A round in September 2018 and signed an exclusive AI partnership with ophthalmic device manufacturer Topcon in October 2018. In November 2019 it launched IDx-DR in CarePortMD, and in June 2020 filed paperwork indicating a $12.5 million raise. The company is also referred to as Digital Diagnostics.
