What is the purpose of this trial?

This trial tests NeoRetina, an AI tool designed to detect and assess the severity of diabetic retinopathy, an eye disease caused by diabetes. The trial aims to determine if this AI can match or outperform regular eye exams. Individuals with type 1 diabetes for at least five years or any type 2 diabetes, who receive care or are on a waiting list for eye evaluations at the Centre hospitalier de l'Université de Montréal, may qualify as candidates. The goal is to improve early detection and treatment planning for those at risk of vision problems due to diabetes. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could enhance future 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.

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

Research has shown that the NeoRetina AI tool is safe for checking diabetic retinopathy, an eye condition in people with diabetes. Studies have found this AI to be highly effective at examining eye images. Specifically, one study showed that NeoRetina correctly identified 91.4% of people with the disease and 95.4% of those without it.

Importantly, these studies did not report any negative effects from using the AI for screening. The process involves taking pictures of the eye, which is non-invasive and painless. Therefore, people using the NeoRetina AI can feel confident about its safety in detecting diabetes-related eye issues. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the NeoRetina algorithm for diabetic retinopathy because it leverages artificial intelligence to enhance early detection of this eye condition. Traditional screenings rely on manual evaluations by ophthalmologists, which can be time-consuming and subject to human error. NeoRetina stands out by using AI to quickly analyze retinal images, potentially increasing accuracy and efficiency in diagnosing diabetic retinopathy. This technology could make screenings more accessible and faster, leading to earlier treatment and better outcomes for patients.

What evidence suggests that the NeoRetina algorithm is effective for detecting diabetic retinopathy?

Research has shown that artificial intelligence (AI) systems, such as NeoRetina, which is being tested in this trial, effectively spot diabetic retinopathy (DR), a condition affecting the eyes. Studies have demonstrated that AI can accurately examine eye images to detect signs of DR, often matching or even surpassing the accuracy of human specialists. One study found that AI systems excel at correctly identifying both those with the disease and those without it. This suggests that NeoRetina is likely very effective at detecting DR from eye images, which is crucial for initiating early treatment. Overall, AI's ability to detect DR appears promising for improving screening methods for this condition. ^{1 4 6 7 8}
