Michigan telemedicine screening for glaucoma and other sight‑threatening eye problems
Official title: Michigan Screening and Intervention for Glaucoma and Eye Health Through Telemedicine- SIGHT 2: A Pragmatic Randomized Trial
Run by University of Michigan · NCT06934577 · Data updated 2026-11-12
This program tests whether a technology-enhanced telemedicine screening finds glaucoma, diabetic eye disease, and visually significant cataracts more often than a standard optometric exam for patients at a community health center.

Is this trial a fit for you?
✓Likely a good fit
Adults receiving care at the participating Federally Qualified Health Center who speak one of the listed languages and do not have acute eye symptoms, recent severe vision loss, or cognitive impairment.
✕Probably not a fit
People with sudden severe eye pain, rapid vision loss within one week, new double vision, cognitive impairment, pregnancy, or who previously declined participation would not be eligible and are unlikely to benefit from enrolling.

What this trial studies
At a Federally Qualified Health Center in Flint, Michigan, patients eligible for routine eye care are assigned to either a standard optometric examination or a technology-enhanced screening protocol that uses digital imaging and telemedicine workflows. Imaging and measurements are reviewed remotely to identify glaucoma, diabetic retinopathy, and visually significant cataract. The study compares detection rates between the two approaches to see which method identifies more cases of these leading causes of blindness. Enrollment supports multiple languages and excludes patients with acute eye symptoms or cognitive impairment.
Why it matters
Potential benefit: If successful, the telemedicine protocol could detect more vision‑threatening conditions earlier and expand access to specialist-level screening at community clinics.
How similar studies have gone: Telemedicine screening programs have previously improved diabetic retinopathy detection in primary care settings, though combining glaucoma and cataract detection in a single technology-enhanced protocol is less well established.
