Description
Neha R Tandon and others tested the repeatability of a new photopic microperimetry approach in geographic atrophy, in 2026. Geographic atrophy damages central vision, and a test that targets the central one millimetre of the fovea could track function more sensitively than broader tests. Before such a test can serve trials, its repeatability must be proven.
Twelve people with non-subfoveal atrophy, seventeen eyes in total, performed focal photopic tests on a forty-five-point grid, twice up to four weeks apart, with other visual function assessments. Repeatability and links to lesion area were studied. Teams gain evidence on whether this focused test is stable enough to detect real change over time.
