Brief Summary

RETeval is a new handheld device intended to detect vision threatening diabetic retinopathy. The purpose of this study is to calibrate RETeval, and then measure its ability to detect vision threatening diabetic retinopathy. Early Treatment Diabetic Retinopathy Study (ETDRS) 7-field, dilated, stereo, color fundus photography, read according to the ETDRS protocol, will be used as the gold standard.

Outcome Measures

Primary Outcomes (1)

  • Per Patient Referral Accuracy

    Accuracy will be reported as count of participants with referral status correctly identified, sensitivity, and specificity, with ETDRS photography and reading as the gold standard.

    During a single visit, implicit time, measured by the RETeval device, and ETDRS photography, will be performed to support the analysis of the accuracy of the RETeval device.
