Yes: artificial intelligence can detect diabetic eye disease from photographs of the retina, and in the United States several systems are cleared to do it without a doctor reviewing the images first. That makes diabetic retinopathy one of the few areas of medicine where AI is already used as an autonomous diagnostic test, not just a second opinion.
The more useful question is how well it works, for whom and where. This article explains what these systems actually detect, what the trial numbers mean, why real-world results can differ, and what a patient should do with a positive, negative or ungradable result.
Quick Answer
Why Diabetic Eye Disease Is a Natural Target for AI
Diabetic retinopathy is damage to the small blood vessels of the retina, the light-sensitive layer at the back of the eye, caused by long-term high blood sugar. It can also cause diabetic macular edema, a swelling of the central retina. In the early stages there are usually no symptoms, and by the time vision changes the disease may already be advanced. That is why people with diabetes are advised to have regular retinal screening.
The problem is not a lack of effective treatment; it is that many people never get screened. AEYE Health, one of the companies in this field, cites estimates that only 15% to 50% of people with diabetes in the U.S. follow screening guidelines. Needing a separate appointment with an eye specialist is one of the main barriers.
Retinal screening also suits AI unusually well. The test is based on a photograph, the signs of disease (tiny bleeds, fluid leaks, abnormal vessels) are visible patterns, and large collections of graded images exist to train and test algorithms. Placing an AI system in a family doctor’s office removes the extra appointment.
How AI Screening Works in Practice
The process is short and, in most systems, takes place during a routine visit:
- Retinal photographs: a trained staff member, not necessarily an eye specialist, takes one or more photos of each eye with a fundus camera. Some systems work without dilating the pupils.
- Image quality check: the software first decides whether the images are good enough to analyze. If not, it asks for new photos or returns an “insufficient quality” result.
- Analysis: the algorithm looks for signs of disease and classifies the result, typically as positive or negative for “more than mild” diabetic retinopathy.
- Result and referral: a positive result means the patient should see an eye care professional. A negative result usually means rescreening at the next recommended interval.
The FDA-Cleared Systems and What Their Studies Showed
Three systems are frequently cited as cleared by the FDA for autonomous diabetic retinopathy screening. Where a peer-reviewed publication exists, the figures below come from it rather than from company announcements.
| System | FDA authorization | Performance reported in pivotal trials | Points to note |
|---|---|---|---|
| LumineticsCore (formerly IDx-DR), Digital Diagnostics | April 2018 | Sensitivity 87.2% (95% CI 81.8–91.2%), specificity 90.7% (95% CI 88.3–92.7%) and imageability 96.1% for more than mild DR, in 900 patients at 10 U.S. primary care sites | The first autonomous AI diagnostic system authorized by the FDA in any field of medicine. Renamed LumineticsCore in 2023; the indications for use did not change. |
| EyeArt, Eyenuk | August 2020 | More than mild DR without dilation: sensitivity 95.5% (95% CI 92.4–98.5%), specificity 85.0% (95% CI 82.6–87.4%). Vision-threatening DR: sensitivity 95.1%, specificity 89.0%. 893 patients analyzed | Reports vision-threatening disease separately. Specificity rose to 87.8% after statistical correction for the study’s enriched sample. |
| AEYE-DS, AEYE Health | November 2022 (desktop camera); April 2024 (handheld camera added) | Sensitivity 93% and specificity 91.4% with a desktop camera; 91.9% and 93.6% with a handheld camera, according to the company’s phase 3 results | Uses one image per eye. Confidence intervals were not available in the sources reviewed for this article. |
Reported sensitivity for more than mild diabetic retinopathy (pivotal trials)
What Happens Outside Clinical Trials
Pivotal trials take place under controlled conditions. Three well-known studies show what can change once AI meets everyday clinics. They looked at different questions, so their results should not be mixed.
Seven algorithms on the same real-world images
Researchers at the University of Washington tested seven AI screening algorithms from five companies on more than 311,000 retinal images from nearly 24,000 veterans screened at VA centers in Seattle and Atlanta between 2006 and 2018. The results, published in Diabetes Care in 2021, showed significant differences between algorithms. Several performed worse than the human graders already working in the VA’s screening program, and performance also varied between the two sites.
The authors concluded that every algorithm should be tested rigorously on real-world data before clinical use. The study population is also worth noting: almost all patients were men with type 2 diabetes, which limits how far the findings can be generalized.
Google’s workflow study in Thai clinics
In a study presented at the CHI conference in 2020, Google Health researchers observed how a deep learning system worked in daily practice across 11 clinics in Thailand. The system had shown high accuracy on research datasets, but in the clinics more than a fifth of images were rejected as too low quality to grade, often because of lighting in the screening rooms. Slow internet connections also delayed uploads, and nurses had to manage patients whose images were rejected.
A large prospective study in Thailand’s screening program
A separate prospective study, published in The Lancet Digital Health in 2022, evaluated a deep learning system within Thailand’s national screening program in 7,651 patients. For vision-threatening diabetic retinopathy it reported a sensitivity of 91.3% and a specificity of 96.3%. This is a different evaluation from the workflow study above: one measured accuracy in a large patient group, the other described how the tool fitted into clinic routines.
Together, these studies illustrate a lesson that applies across medical AI: an accurate algorithm is only one part of a working screening service. Cameras, lighting, staff training, connectivity and referral pathways matter just as much.
What Your Result Means
| Result | What it means | What to do |
|---|---|---|
| Positive | Signs of diabetic retinopathy above the referral threshold were detected. It is not a diagnosis of severity. | Book the referral with an eye care professional promptly. The benefit of screening depends on this follow-up. |
| Negative | No referable diabetic retinopathy was detected in these images. | Keep to your recommended screening interval. It does not rule out other eye conditions. |
| Ungradable / insufficient quality | The images could not be analyzed. This is not a negative result. | Ask how and when you will be examined instead, for example with new photos, dilation or an eye clinic appointment. |
What AI Screening Does Not Do
- It screens for one disease. These systems are designed to detect diabetic retinopathy. A negative result does not rule out glaucoma, cataract, age-related macular degeneration or other conditions a full eye exam can find.
- It has a defined intended use. FDA clearances typically cover adults with diabetes who have not already been diagnosed with more than mild diabetic retinopathy. People already under follow-up for retinopathy should continue with their eye specialist.
- It depends on the approved equipment. Each clearance is tied to specific cameras. Results with other devices are not covered by the same evidence.
- It is not a treatment decision. A positive result means “see a specialist”, not a decision about what treatment is needed.
- It does not replace symptoms. Sudden vision changes, new floaters, flashes or loss of vision need prompt medical attention whatever a recent screening showed.
Is AI Diabetic Eye Screening Available in Europe?
FDA clearance in the United States does not by itself establish that a system is authorized or used in the same way in Europe. Availability depends on each device’s European regulatory status and intended use, and on how national and regional health services organize screening. EyeArt, for example, reports CE marking as a class IIa medical device in the European Union.
For patients in Spain and other European countries, AI should be seen as a possible way to support diabetic retinopathy screening, not as a replacement for the eye examinations and follow-up recommended by their healthcare team. The practical step is to ask your diabetes care team or local ophthalmology service which screening pathway is used where you live.
Lesson for Patients: Using AI Screening Well
If you are offered AI retinal screening, these checks help you get real value from it:
- Ask what the test looks for: diabetic retinopathy only, or other conditions too.
- If the result is positive, make sure the referral appointment is booked.
- If the images were of insufficient quality, ask what happens next rather than assuming all is well.
- If the result is negative, ask when you should be screened again.
- Tell the clinician if you already have a retinopathy diagnosis, are pregnant, or have other eye conditions, since these may change whether AI screening is appropriate.
- Report any change in vision immediately, even soon after a normal result.

The Bottom Line
Frequently Asked Questions
How does AI screening compare with an eye exam by an ophthalmologist?
For one specific task, detecting more than mild diabetic retinopathy in retinal photographs, FDA-cleared systems showed high sensitivity and specificity in their pivotal studies. An ophthalmologist’s examination covers much more: other diseases, the severity of retinopathy and treatment decisions. Real-world studies also show that performance varies between algorithms and settings.
Do I need eye drops for an AI screening?
Not always. Several systems are designed to work without dilating the pupils, although dilation may be needed if the images are not clear enough. In the EyeArt pivotal study, for example, dilating eyes with ungradable images raised the share of gradable eyes from 87.4% to 97.4%.
Can AI screening detect glaucoma or macular degeneration?
The FDA-cleared autonomous systems described here are indicated for diabetic retinopathy. AI research is exploring other eye diseases, but a negative diabetic retinopathy screening should not be taken as a check for other conditions.
What should I do if my images could not be analyzed?
Treat it as an incomplete test, not as a normal result. Ask the clinic whether new photos, pupil dilation or a referral to an eye service is the next step.
