Showing retinal images improves diabetes

Researchers from the Royal Victorian Eye and Ear Hospital in Melbourne compared glycaemic control in 25 patients three months after they were shown their own retinal images, those of healthy retinas and eyes with varying degrees of progressive retinopathy.

HbA1c in patients who had seen their retinal images decreased by 0.6%, compared with an increase of 0.3% in the control group who saw no images.

Motivation to improve glycaemic control was higher, and concern about retinopathy lower, in the intervention group compared with controls.
