A Tale of Two Patients: How ERG Uncovered Hidden Differences

Explore how Dr. Kelly MacDonald treated two patients that visited her office in the same day and presented very similarly, until ERG uncovered their hidden differences.

ERG Supports Treatment Decision in Diabetic Retinopathy

For some patients with DR, the decision to initiate laser treatment can be difficult. In some cases, favorable RETeval results may support monitoring the patient over time instead of treating immediately.

ERG Demonstrates Stable Function Despite Severe Structural Damage

Explore how the RETeval provided an objective, non-invasive way to monitor progression of ganglion cell function.

Study Identifies RET<i>eval</i> DR Score as the Strongest Predictor of Diabetic Retinopathy Progression

Differential Diagnosis of Glaucoma-Like Lesions Using Photopic Negative Response 

Explore how photopic negative response (PhNR) testing helped differentiate glaucoma-like lesions from normal anatomical variants in an adult patient. Case study by Bartłomiej Kocurek & Prof. Adrian Smedowski, Medical University of Silesia.

Photopic Negative Response as a Reliable Method for Glaucoma Follow up in Children 

Using PhNR for pediatric glaucoma monitoring when OCT and perimetry aren’t possible.
This case study from the Medical University of Silesia demonstrates how the Photopic Negative Response (PhNR) test using the RETeval® ERG device supported diagnosis and treatment monitoring in a 7-year-old girl with congenital glaucoma.

Vision Complaints Reflected on ERG

Faced with a diabetic patient reluctant to change his habits despite bothersome vision loss, Dr. Nate Lighthizer used the RETeval DR Score to demonstrate risk and motivate him to begin nutritional supplementation.

The Predictive Value of Combining Diagnostic Technologies

Explore this case as Dr. Paul Chous leverages his RETeval to determine an appropriate follow-up schedule.

ERG Provides Clarity When Fields and OCT are Inconclusive

Explore this case by Dr. Michael Cymbor that represents the complexity and overlap between diabetic retinopathy and hypertensive retinopathy.

ERG Raises Red Flag, Changing Management Trajectory

A complaint of difficulty driving at night is not uncommon for an optometrist to hear, but when one patient mentioned this during his routine exam, his visual acuity of 20/20 signaled Dr. Frances Bynum, OD, FAAO, to look further.

ERG Provides Confidence to Monitor or Treat
