In subjects with no or mild DR, macular and foveal thickness is significantly thinner with longer duration of disease. This may reflect neurodegenerative changes in the diabetic retina.

Recommended follow-up from JVN imaging compared favorably to clinical examination by a retinal specialist. Nondiabetic ocular pathology was identified. JVN assessment of DR level compares favorably to clinical practice, potentially improving access to eye care and enhancing diabetes management.

Retinal thickness as measured by Stratus OCT in the fovea and macula is significantly thinner in blacks compared with age-matched whites. Larger multiracial prospective studies are needed to confirm these results and to evaluate the need for race-specific normative values.
