Objective Look at Localized Retinal Dysfunction.
As eye care specialists, you frequently co-manage patients with other health care providers such as primary care physicians, rheumatologists, and neurologists. This often makes you the first line of detection when certain medications prescribed by those physicians start negatively impacting the patient’s retina. In some cases, retinal dysfunction may occur without structural abnormalities, requiring a robust functional testing method to detect retinal toxicity early.1-3 Diopsys® mfERG (multifocal electroretinography) vision tests provide you with the objective, functional information you need to help recognize the first signs of drug-induced retinopathy, and work with the other providers to make the best clinical decisions for each patient.
- Objectively monitor function loss and recovery with objective, quantitative metrics1-2
- Co-manage patients more efficiently for more timely changes to treatment
- Clear, intuitive report interpretation
Multifocal Electroretinography (mfERG) Vision Testing
Multifocal ERG has been recognized as an effective test in helping doctors to diagnose and manage diseases affecting the retina, most notably retinal toxicities.1-3 This visual electrophysiology technique is a test of localized retinal function through quasi-simultaneous stimulation of different areas of the retina.4 The American Academy of Ophthalmology (AAO) recommends the use of multifocal electroretinography for chloroquine (CQ) and hydroxychloroquine (HCQ) retinopathy screening.3

Diopsys provides an in-office ERG platform that allows clinicians to establish a functional baseline in diabetic retinopathy, and then follow disease in a way that we can’t otherwise.
In my 40 some years in this business, this is the first time that we’ve been able to get real, objective evidence of how the retina’s doing in a host of conditions.
Now I have a reliable, objective test of retinal function that I can perform pre-operatively to give me an idea of what's going on behind the cataract. Flicker ERG has helped me ensure that these patients are accurately prepared for the outcome of their surgery.
