Predicting Diabetic Retinopathy From Risk Factor Data and Digital Retinal Images

This study represents the third aim of a grant with five aims. The study will compare and
evaluate the predictive accuracy of: (a) machine learning models developed to grade diabetic
retinopathy and assess the presence or absence of diabetic macular edema and (b) the
assessments of optometrist readers, both from digital retinal images, against standard of
care dilated retinal examinations by board-certified ophthalmologists and/or
retinal-specialty fellows for 300 diabetic patients utilizing a Los Angeles County reading
center.

For the study, the investigators will recruit 300-500 eligible diabetic patients for
in-person eye examinations performed by board certified ophthalmologists and/or
retinal-specialty fellows at Los Angeles County reading centers. The study will take place
over the course of two visits: a teleretinal screening and an in-person eye examination.

The in-person dilated eye examinations that the study participants will participate in and be
compensated for follow the usual standard of care that patients receive in a setting that
does not utilize teleretinal screening. Yearly dilated eye examinations are standard of care
for all persons with diabetes.

Inclusion Criteria:

- Patients diagnosed with Type I or Type II Diabetes,

- Patients who are over the age of 18 years

- Patients who have not previously been seen in the current year by the LACDHS
Teleretinal Diabetic Retinopathy Screening Program and Reading Center

Exclusion Criteria:

- Patients under the age of 18 years

- Patients with gestational diabetes

- Patients who have previously been seen in the current year by LACDHS's Teleretinal
Diabetic Retinopathy Screening Program and Reading Center

- Previously eligible patients who do not return for an in-person eye exam within 3
months of receiving a teleretinal screening (In order for the results of the
teleretinal screening and in-person eye examinations to yield similar information,
patients who do not return for their in-person eye exam within 3 months of their
teleretinal screening will not be able to remain in the study. This is because
significant eye changes not documented by the teleretinal screening may occur after a
3-month period).
