摘要：
A visual distortion test is disclosed using a sequence of binary interactions with a mobile device, in which segments of the grid having no distortions are eliminated, and the segments with distortions are divided into smaller segments for further analysis. The test can quantify the visual distortion using a decreased number of steps, compared to sequential analysis of all the segments of the grid. The binary interaction or input to the mobile device is also easier for patients than graphic interactions with a conventional Amsler Grid. Early detection of changes in the visual distortion can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.
