Diabetic retinopathy is increasingly prevalent, affecting an estimated 9.6 million individuals in the US, with nearly 2 million at the vision-threatening stage. As the need for effective risk management rises, electroretinography (ERG) emerges as a valuable tool to identify functional retinal changes before structural alterations. Current handheld ERG devices facilitate efficient, non-invasive testing. Recent studies highlight ERG's predictive capabilities, prompting a shift in diabetic eye care towards proactive intervention strategies focused on preserving vision.
- Diabetic retinopathy affected 9.6 million in the US in 2021.- Nearly 2 million are in vision-threatening stages.- Handheld ERG devices are efficient and non-invasive.- ERG detects functional changes before structural ones.- RETeval DR Score predicts progression to complications.- ERG is included in AAO guidelines for diabetic retinopathy.- Early intervention can preserve vision outcomes.
