Can telemedicine help prevent blindness in diabetes patients?
NCT ID NCT05773495
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests a program called I-SITE that helps clinics use teleophthalmology—taking eye photos during regular doctor visits—to increase screening for diabetic retinopathy. Over 12,000 patients with diabetes from urban health systems are included. The goal is to see if this approach leads to more people getting their eyes checked regularly.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could show how to make diabetic eye screening more routine and accessible, potentially preventing vision loss in many patients.
- What could go wrong
- This is an implementation study, not a test of a new treatment. It may not change screening rates significantly, and results may not apply to all clinics.

Inclusion Criteria: * Eligible medical records will be identified using ICD-10 codes for diabetes type 1 or type 2 * Billing data will be identified using teleophthalmology (CPT codes 92228 or 92250) * Identification of eligible records will be performed by clinic personnel at each health system who already have full access to their patient data as part of their employment, and regularly gather and report this type of data to health insurers as part of their clinical role Exclusion Criteria: \-
