Objective:

To evaluate the diagnostic utility of pupil diameter (PD) difference under varying lighting conditions as a biomarker for assessing chronicity of diabetes and autonomic neuropathy, specifically focusing on its implications for clinical monitoring.

Approach:

Key Findings:

• The PD difference was significantly lower in the diabetic group (0.94 ± 0.44) compared to controls (1.21 ± 0.48), indicating a potential diagnostic marker.
• Patients with diabetes duration of >1 year showed a significant decline in PD difference compared to controls, highlighting the impact of disease duration.
• ROC analysis indicated that PD difference is a viable clinical endpoint for assessing diabetes chronicity, with implications for patient management.

Interpretation:

Quantitative pupillometry may serve as a useful tool for monitoring diabetic autonomic neuropathy and disease chronicity.

Limitations:

• The study was limited to a single center and may not be generalizable across diverse populations.
• Potential confounding factors, such as variations in medication use and lifestyle factors, were not fully accounted for in the analysis.

Conclusion:

Quantitative measurement of pupil diameter under varying light conditions can provide valuable insights into the autonomic status of diabetic patients, potentially guiding clinical management.
