 The results of this study will provide the basis for patient self-monitoring of visual function with the myVisionTrack, and for reporting, storage, and maintenance of collected data. The myVisionTrack is intended to be used remotely by patients to monitor their disease. In the case of significant changes, patients will be prompted to visit their ophthalmologist. It is hypothesized that this can lead to earlier detection of disease progression, which, in turn, can lead to earlier treatment and better prevention against vision loss due to diabetic retinopathy DR.
