PREDICT AND PROTECT WITH HANDHELD ERG
The Diabetic Retinopathy Test to Predict Your Patient’s Future
Give your patients the advantage of timely, actionable information with the only handheld ERG that delivers an objective diabetic retinopathy exam: the RETeval®.
As a clinician, you want to protect your patient’s vision – but diabetic retinopathy progression isn’t always predictable.
Traditional imaging may not reveal functional damage until it’s too late, especially in non-proliferative stages. That means missed opportunities for timely diabetic retinopathy treatment and better patient outcomes.
The RETeval Solution:
- Predictive DR Score – Stratify progression risk and determine which patients need more of your time and attention
- Non-invasive – No dilation, no corneal contact
- Efficient – Test in minutes, train staff quickly, integrate into any workflow
- Versatile – Ideal for primary and specialty care
Backed by science
Landmark Research
The RETeval handheld ERG’s objective DR Score has been validated by more than 20 peer-reviewed publications since 2016. Explore the full research library here.
2025: Waheed
RETeval DR Score ≥ 26.9 predicts 5.6x relative risk for progression from moderate to severe NPDR to vision-threatening complications in less than 1 year.

2020: Brigell
RETeval DR Score ≥ 23.5 predicts an 11-fold risk of requiring intervention in 3 years.

Why the DR Score Matters
Latest research confirms a RETeval DR Score ≥ 26.9 outperforms 55 diagnostic parameters on 4 testing modalities, including OCT-A, ultra-widefield fluorescein angiography, and fundus in predicting progression to vision-threatening complications within 1 year.
- Allows targeted referrals and/or resource prioritization, reducing overtreatment and missed progression
- Creates potential to improve DR staging systems and support value-based care models
- Supports evidence for inclusion of ERG in the American Academy of Ophthalmology’s updated Preferred Practice Pattern for detecting and managing DR
The relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. Together with risk difference and odds ratio, relative risk measures the association between the exposure and the outcome.
SCHEDULE A DEMORETeval: Making a Difference in Diabetic Retinopathy Care
ERG Named in Preferred Practice Pattern Guidelines for Diabetic Retinopathy
The American Academy of Ophthalmology’s inclusion of ERG demonstrates its valuable role in both diagnosing and managing diabetic retinopathy. This decision reflects the growing recognition that objective, functional testing, alongside structural imaging, is critical for a comprehensive DR assessment.

“The inclusion of ERG in the AAO’s Preferred Practice Pattern guidelines is a pivotal moment in eye care history. As diagnosticians and treating physicians, we need an objective, functional complement to structural imaging. ERG provides this, helping us detect early retinal dysfunction that may precede visible structural changes.”
