Clinical Report: Bidirectional Relationship Between Diabetic Retinopathy and Anxiety/Depression
Overview
This meta-analysis of 34 studies involving 383,195 patients demonstrates a significant bidirectional association between diabetic retinopathy (DR) and depression, as well as a positive correlation between DR and anxiety. The findings highlight the importance of addressing psychological health in patients with DR to improve outcomes.
Background
Diabetic retinopathy is a common microvascular complication of diabetes mellitus and a leading cause of vision impairment and blindness in working-age adults. Its pathological features include microvascular damage leading to retinal ischemia and neovascularization. The global prevalence of DR is rising alongside diabetes, affecting over 100 million adults worldwide. Patients with DR often experience anxiety and depression, which may worsen glycemic control and treatment adherence, creating a complex interplay between ocular and psychological health.

Key Findings
A significant positive correlation exists between diabetic retinopathy and depression (OR=1.58; 95% CI: 1.24-2.02; p<0.001).
Depression significantly increases the risk of developing diabetic retinopathy (OR=2.13; 95% CI: 1.53-2.98; p<0.001), indicating a bidirectional relationship.
Diabetic retinopathy is also positively correlated with anxiety (OR=2.23; 95% CI: 1.07-4.68; p=0.033).
The prevalence of depression and anxiety among patients with DR is notably high, at 34.3% and 41.1% respectively.
Psychological distress in DR patients may contribute to poorer glycemic control and lower treatment compliance, exacerbating disease progression.
Clinical Implications
Clinicians should incorporate routine psychological screening and personalized mental health care into the management of patients with diabetic retinopathy. Addressing anxiety and depression may improve treatment adherence and glycemic control, potentially mitigating DR progression and enhancing patient quality of life.
Conclusion
This comprehensive meta-analysis confirms a bidirectional relationship between diabetic retinopathy and depression, as well as a positive association with anxiety. Integrating psychological care into DR management is essential to break this vicious cycle and improve clinical outcomes.
In a target-trial emulation of more than 600,000 veterans, GLP-1 RA initiators saw fewer new substance use disorders—and patients with existing SUDs had fewer overdoses, hospitalizations, and deaths.
