Early Detection.
Early detection and treatment is the key to maintaining a lifetime of healthy vision for your patients. Diopsys® ERG (electroretinography) vision tests provide you with objective, functional information on the performance of retinal ganglion cells. These test results help you identify “stressed” cells at a subclinical stage, when the cells have become dysfunctional but are still alive.1 By starting treatment at this early stage, before evident structural defects, you can help extend your patients’ sight.
- Objectively measure functional loss and recovery2
- Enhanced treatment tracking and disease management
- Clear, intuitive report interpretation
Pattern Electroretinography (ERG) Vision Testing
ERG has been recognized as an effective test in helping to diagnose and manage disease including, Glaucoma, Age-Related Macular Degeneration (AMD), and Diabetic Edema, among others.3 4 5 Clinical Support for pattern ERG testing comes from leading eye care institutions including the American Academy of Ophthalmology, Bascom Palmer Eye Institute, and Wills Eye Hospital.3 6 7

Pattern ERG is a technology that allows us to have earlier diagnosis or confirmation of glaucoma than anything else that we currently use.
