Enhanced Patient Management.
Understanding how your patient is responding to treatment is important. Is their visual function improving? Is their disease progressing? Diopsys® ffERG (full field electroretinography) vision tests provide you with objective information on retinal function. These test results may be used to indicate the level of functional loss and recovery on patients with retinopathies,1 and give you the added ability to measure the effect of retinopathies on vision through the presence of cataracts.2 3 This may be particularly helpful in managing patient expectations prior to IOL procedures.
- Objectively measure functional loss and recovery1
- Enhanced treatment tracking and disease management
- Clear, intuitive report interpretation
Full Field / Flicker Electroretinography (ffERG) Vision Testing
ffERG has been recognized as an effective test in helping doctors to diagnose and manage disease including diabetic retinopathy and central retinal vein occlusions, among others.4 5 It has also been shown to help in in cases of media opacities sufficiently dense to prevent a clear image being projected onto the retina.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.
