Background/Objectives: A novel, handheld, standalone device using shape discrimination hyperacuity has been developed to remotely monitor age-related macular degeneration (AMD). Methods: We clinically validated the device in an outpatient dry AMD population to evaluate its usability and comfort. A cross-sectional study was conducted with subjects aged 50 years or older with dry AMD at the University of Michigan Kellogg Eye Center outpatient clinic after approval from the UM IRB (HUM00187177). Subjects used the device and then completed a device survey and System Usability Scale (SUS). Results: Thirty-one subjects completed the study, and one subject withdrew post-study completion (mean age 77 years, STD 8 years). The mean testing time was 126 s (STD 56 s), and the median was 116 s. Most patients reported that the use of the device occurred for an acceptable duration (97%), was easy (97%), and was comfortable (90%). The mean SUS score was 77.7 (STD 11.9). Conclusions: A handheld, standalone device can provide a rapid, easy, and comfortable testing solution for patients with dry AMD. The usability of the device supports further clinical trials to demonstrate the device’s ability to reliably detect the progression of AMD.
