Purpose: To assess the clinical value of reporting full-field electroretinogram (eg, flicker ERG) findings graphically to determine the severity of diabetic retinopathy (DR) within an office-based setting.
Methods: Patients with type 2 diabetes mellitus were included and classified into varying degrees of DR based on presence and severity. Flicker ERG responses were recorded and compared between groups.
Results: Between the varying disease stages, significant differences in the mean magnitude and phase values were found. There was also a significant difference between the proportions of the magnitude and phase color-coded frequencies between groups of severity and threat to vision.
Conclusion: Magnitude and phase parameters of the flicker ERG test may be used to stage disease severity in patients with ongoing DR and determine risk of worsening. With utilization of these values organized into a visual diagram, interpretation of the recording may be more efficient and facilitate appropriate management of DR within the primary care setting.
