Evaluation of inner retinal function in myopia using oscillatory potentials of the multifocal electroretinogram [PDF]

, 2006
PurposeOscillatory potentials have been suggested to arise from the inner retina at the level of amacrine cells and inner plexiform layer and they are thought to provide a non-invasive assessment of inner retinal function.
