What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to enhance eye care for people with diabetes by using artificial intelligence (AI) to make eye screenings faster and more accessible. The AI system, equipped with a special camera, analyzes eye images to help identify diabetic retinopathy, a condition that can impair vision. Participants will either receive an AI-based screening (Diabetic Retinopathy Screening Point-of-Care Artificial Intelligence) during a doctor's visit or follow the usual care process at a separate time and place. This trial suits individuals with diabetes who have not had a detailed eye exam in the past 11 months and are patients at San Ysidro Health. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could transform eye care for diabetic patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on eye screenings rather than medication changes.

What prior data suggests that this AI technology is safe for diabetic retinopathy screening?

Research has shown that using artificial intelligence (AI) to screen for diabetic retinopathy, an eye condition that can cause vision loss, is safe. The AI system, EyeArt®, has been used successfully in the past. It provided clear results for over 97% of eyes checked without needing to dilate the pupils, making the process less invasive and more convenient.

Additionally, the FDA has approved this AI technology for diabetic retinopathy screening, indicating it meets safety standards. The AI system is highly accurate, with 87% sensitivity (correctly identifying those with the condition) and 90% specificity (correctly identifying those without the condition). These findings ensure that the screening process is both effective and well-tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using artificial intelligence (AI) for diabetic retinopathy screening because it offers rapid, on-the-spot results. Unlike traditional screenings, which require scheduling separate appointments with specialists, this AI system—EyeArt®—enables patients to get screened and receive results during the same visit, even without eye dilation. This immediacy not only streamlines the process but also empowers patients with instant insights into their eye health, facilitating timely discussions with their healthcare providers.

What evidence suggests that this AI screening is effective for diabetic retinopathy?

This trial will compare the effectiveness of an AI system for diabetic retinopathy screening with usual care. Studies have shown that artificial intelligence (AI) systems effectively detect diabetic retinopathy, a condition that can harm the eyes of people with diabetes. These AI tools excel at identifying both those with and without the condition, often matching or surpassing the accuracy of human experts. For example, one study showed that an AI system correctly identified 92% of people with the disease and 88% of those without it, demonstrating its high success in detecting the disease. This technology enables quick and accurate eye exams, helping doctors find and treat problems earlier. AI screenings can make these important tests more accessible to those who need them, potentially improving overall eye health for people with diabetes. ^{1 2 4 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Diabetic Retinopathy Screening Point-of-Care Artificial Intelligence

Trial Overview

The intervention being tested is an artificial intelligence system that screens for diabetic retinopathy by analyzing digital images of the eyes. This study evaluates the effectiveness of AI in aiding diagnosis and treatment plans.

How Is the Trial Designed?

Group I: Diabetic Retinopathy Screening Experimental Treatment 1 Intervention

The intervention group will complete the DR screening using a special camera and the AI system (EyeArt®), the same day of the study visit. Participants assigned to the intervention group will also receive a retinal screening without dilation using the EyeArt® AI system; the DR screening will be completed before their medical provider visits. The results will be available immediately after the screening, allowing participants to learn about and discuss their eye health with their care provider.

Group II: Usual care Active Control 1 Intervention

The usual care group will complete the DR screening with an eye care provider on a different day and at a different location. The study staff will facilitate this process for participants in the usual care group by assisting them in scheduling appointments for their routine retinal screening.

Published Research Related to This Trial

The AI-based screening tool EyeWisdom®DSS demonstrated high sensitivity (91.0%) and good specificity (81.3%) for detecting diabetic retinopathy (DR) in a study of 549 type 2 diabetes patients, indicating its effectiveness as a screening method.

EyeWisdom®MCS was particularly effective at identifying patients without DR, with a specificity of 92.4%, suggesting that AI screening can be a valuable resource in areas with limited access to eye care.

The IDx autonomous diabetic retinopathy screening program demonstrated a perfect sensitivity of 100% in detecting referable diabetic retinopathy, but had a lower specificity of 82%, leading to a high rate of unnecessary referrals.

With a positive predictive value of only 19%, the program may overwhelm ophthalmologists and primary care clinics, suggesting a need for improved AI systems that can provide better specificity and detailed lesion annotations to enhance patient management and treatment adherence.
