Objective:

To assess the progression of diabetic retinopathy (DR) in a patient with type 2 diabetes using electroretinography (ERG), highlighting the significance of ERG in monitoring retinal health.

Key Findings:

• Initial retinal findings indicated unilateral DR, which progressed to bilateral DR over time, particularly after the introduction of GLP-1 treatment.
• The patient's HbA1c improved with GLP-1 treatment, but retinal health deteriorated, suggesting a potential adverse effect of the medication.
• ERG scores indicated a significant risk of requiring intervention due to DR, highlighting the importance of monitoring.

Interpretation:

The case highlights the importance of monitoring retinal health in diabetic patients, especially those on GLP-1 agonists, as they may have adverse effects on DR progression.

Limitations:

• The patient's delayed follow-up may have contributed to the progression of DR, emphasizing the need for timely monitoring.
• The study is based on a single case, limiting generalizability and necessitating further research.

Conclusion:

Regular monitoring and early intervention are crucial in managing diabetic retinopathy, particularly in patients undergoing treatment for diabetes, as GLP-1 agonists may pose risks to retinal health.
