title: The multifocal electroretinogram in age-related maculopathies.
abstract: To measure and compare the multifocal electroretinogram in control group and patients with age-related maculopathies, 17 eyes of control subjects, 9 eyes of wet-form ARMD, 8 eyes of dry-form ARMD and 14 eyes of idiopathic macular hole were tested with VERIS Sciences 4.0. The latencies and average response densities of 6 ring retinal regions in control eyes were compared with those in ARMD and macular hole. The amplitude depression and latency prolongation were found in age-related maculopathies. The changes of multifocal ERG were dramatic in wet-form ARMD and moderate in dry-form ARMD and IMH, which were correspondent with the pathological changes of the diseases. Our results suggest that the multifocal electroretinogram can be used to quantity the visual function in age-related maculopathies.
