Patients are instructed to test their prescribed eye(s) daily, and their responses are automatically transmitted to the Notal Vision Data Monitoring Center (DMC) at the end of each test. The wireless communication technology facilitates fast and reliable transmission of data, which is then made available to the physician through a secure website. Tests are continuously compared to a normative database threshold and the patient’s own baseline. When a statistically significant change of test patterns is detected, the DMC alerts the clinic so that they can schedule a prompt clinical examination with the patient.
In addition to monitoring test scores, the frequency of use is also tracked. To encourage patients to test at an adequate frequency (i.e., one that will allow timely detection in a conversion event), the DMC will contact the patient if no results are received for 7 consecutive days.
