To conduct a pilot study to explore the potential impact of visual feedback of personal retinal images on diabetes outcomes.
METHODS:
Twenty-five participants with non-proliferative diabetic retinopathy and suboptimal HbA1c (> 53 mmol/mol; > 7%) were randomized to receive visual feedback of their own retinal images or to a control group. At baseline and 3-month follow-up, HbA1c, standard measures of beliefs, diabetes-related distress and self-care activities were assessed.
RESULTS:
In unadjusted models, relative to controls, the intervention group showed significantly greater improvement in HbA1c at 3-month follow-up (–0.6% vs. +0.3%, P < 0.01), as well as enhanced motivation to improve blood glucose management (P < 0.05).
CONCLUSIONS:
This small pilot study provides preliminary evidence that visual feedback of personal retinal images may offer a practical educational strategy for clinicians in eye care services to improve diabetes outcomes in non-target compliant patients. A fully powered randomized controlled trial is required to confirm these findings and determine the optimal use of feedback to produce sustained effects.
