Sponsor

University of Michigan

Enrollment

900 participants

Start Date

Dec 4, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

To compare eye disease detection rates at a Federally Qualified Health Center between a technology-enhanced protocol and standard optometric clinical examination for three of the leading causes of blindness: glaucoma, diabetic retinopathy, and visually significant cataract.


Eligibility

Min Age: 18 Years

Inclusion Criteria1

  • • Speak English, Spanish, Arabic, Chinese, French, Hindi, Finnish, Albanian, Russian or Tagalog

Exclusion Criteria6

  • significant eye pain
  • sudden decrease in vision within one week
  • binocular diplopia
  • cognitive impairment
  • pregnancy
  • previously declined participation

Interventions

OTHERStandard optometric examination

Participants will see the optometrist at the Federally Qualified Health Center. The guidelines define usual care as: an in-person comprehensive eye examination with assessment of patient history, visual acuity, pupil examination, ocular motility and alignment, intraocular pressure, and biomicroscopy with additional tests, as appropriate. A glasses prescription will be given to the participant if needed. Participants will complete surveys at baseline before their eye exam and 6 weeks after the eye exam.

OTHERTechnology enhanced eye disease detection protocol

Participants will receive a technology enhanced eye disease detection protocol from ophthalmic technicians that includes measurements of visual function such as visual acuity, refraction, intraocular pressure, pachymetry, external eye and fundus photography, and optical coherence tomography of the macula and retinal nerve fiber layer. The optometrist at the Federally. Qualified Health Center will then use a protocol to grade the testing and identify eye disease. The results of the grading will inform whether the person receives a brief appointment with the optometrist (no disease detected) or an in-depth appointment with the optometrist (disease detected). During the first visit, participants receive care navigation support to purchase low-cost glasses from an on-line retailer. When participants return for the optometrist exam, glasses will be fit. Participants will receive care navigation support to attend any recommended specialty follow-up appointments.
