Maziade is confident that electroretinography will soon enter the clinic. In 2015, he co-founded diaMentis, a personalized-medicine company in Quebec City that is developing software for electroretinography-signal analysis. Within three years, Maziade says, the company’s software should be advanced enough to help clinicians to make accurate diagnoses of schizophrenia.
