“The RETeval has been a game changer for my practice and I use it on about 10-15 patients with general retinal diseases and glaucoma everyday across our 6 RETeval units in our 6 office sites. I cannot recommend the device more highly for your practice”

“We use the RETeval device to screen the patient as soon as they walk in the door, and then we test them every year to see what’s going on and see how the function of the retina is changing. This device is revolutionary and provides objective and easy to interpret information in a way that can’t be obtained from any other device”

“We have been very pleased with the RETeval. It has changed the way that we practice and has allowed us to significantly decrease the amount of EUAs with ERGs we perform. Furthermore, it has resulted in earlier diagnosis of patients with inherited retinal degenerations.”
