Early Detection.
Enhanced Patient Management.

What if you could more accurately evaluate a patient's future vision?

Right now. In your practice.

Practice-based eye care specialists are now able to obtain objective, functional information to help detect disease earlier and enhance patient management1-3 using Diopsys® ERG and VEP Vision Testing Systems. Electroretinography (ERG) and visual evoked potential (VEP) results are not just for rare disorders, but also for the early diagnosis and management of more common diseases like glaucoma, AMD, and diabetic retinopathy.1-3

  • Easily integrated into practice flow
