About this trial

This is a clinical trial to evaluate the effects of universal screening for diabetic retinopathy (DR) and diabetic macular edema (DME) using artificial intelligence (AI) in the interpretation of fundus photographs obtained by trained nursing assistant using a portable fundus camera in a primary care setting, compared with images obtained by the same method, but interpreted by ophthalmologists.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adults (> 18 years old) diagnosed with diabetes mellitus who agree to participate in the study.

Disqualifiers

Any contraindication for pharmacological mydriasis (such as knowledge of having closed-angle glaucoma, pregnancy).

Life expectancy less than 6 months

Trial design

Design model

Parallel

Treatments tested in this trial

  • Mobile retinography interpreted by artificial intelligence

    Diagnostic test

    All participants will undergo mobile retinal photography in primary care by a trained nursing assistant. If randomized to RDIA group, their photos will be analyzed by artificial intelligence.

  • Mobile retinography interpreted by ophthalmologists

    Diagnostic test

    All participants will undergo mobile retinal photography in primary care by a trained nursing assistant. If randomized to RDOF group, their photos will be interpreted remotely by ophthalmologists.

Treatment groups

922 Participants
are divided into 2 treatment groups

Trial outcomes

Primary outcomes

1

Number of appropriate referrals to ophthalmologist

Appropriate referrals: asymptomatic patients with moderate to severe nonproliferative DR, proliferative DR, significant macular edema, and uninterpretable exams. This data will be obtained by reviewing the medical records of ophthalmological in-person consults of included patients.

Time frame
Through study completion, an average of 1 year

Secondary outcomes

1

Number of patients referred for laser sessions

Considering only patients referred for argon laser sessions aiming retinal photocoagulation for the treatment of diabetic retinopathy. This data will be obtained through access to the medical records of patients referred for specialized care.

Time frame
Through study completion, an average of 1 year
2

Number of pharmacological intraocular treatment

Considering treatment with anti-VEGF drugs or intravitreal corticosteroids for the treatment of diabetic retinopathy and diabetic macular edema. This data will be obtained through access to the medical records of patients referred for specialized care.

Time frame
Through study completion, an average of 1 year
3

Referral failure

Screening with false negative result. This data will be obtained by an independent ophthalmologist review of all images of the not referred patients.

Time frame
After study completion, an average of 15 months
