Design outcomes

Primary

MeasureTime frame
1. Development of patient-relevant PerfOs based on smartphone usage and accelerometer data for use in chronic eye diseases that primarily affect central vision (e.g., AMD) or peripheral vision (e.g., glaucoma), with a focus on the domains of reading and mobility 2. Initial cross-sectional and longitudinal validation of the digital PerfOs using a clinical cohort (construct validity, criterion validity, sensitivity to change)

Secondary

MeasureTime frame
1. Stratification of the quality of endpoints and various PerfO endpoint categories (smartphone, accelerometer) compared to relevant PROMs (Vision Impairment in Low Luminance (VILL) questionnaire) 2. Generation of innovative, ophthalmologically relevant accelerometer-based endpoints obtained using the activPAL 3. Development of endpoints for the creation of a smartphone application for self-monitoring of digital behaviors as an ophthalmological study endpoint
