Mixed methods study shows high usability and diagnostic sensitivity in patients with macular disease, suggesting potential for home use.
The GridMacuScan application demonstrated diagnostic sensitivity comparable to that of the traditional Amsler grid and received high user ratings for usability. Furthermore, it provided quantitative distortion metrics that could facilitate longitudinal disease surveillance. Future research must be conducted to validate performance in unsupervised home environments and investigate whether sustained use improves time-to-disease-progression detection and treatment outcomes.
