Description
Diabetic retinopathy harms the eye at different rates in different groups, and race may shape how the disease develops. The authors run a pilot study of retinal oxygen measures in 104 people: some without diabetes, some with diabetes but no eye disease, and some with mild disease. Using oximetry and a Doppler form of optical coherence tomography, they measure oxygen delivery, oxygen use, and the share of oxygen extracted by the inner retina. Participants are grouped as Asian, African American, Hispanic White, or non-Hispanic White.
Race and diagnosis interact in the results. Among Asian participants, oxygen use is lower in the diabetic group without eye disease than in the mild disease group. Other patterns differ by group as well, with no single trend across all races. The authors present these early findings as a reason to build race-specific baselines in larger studies before using such measures in clinic.
