de Souza Lima LCS, et al. – A comparative analysis was performed of the anisometropic hypermetropic amblyopic and strabismic amblyopic responses to pattern electroretinogram (PERG) and pattern visual evocated potential (PVEP). Although there existed clinical differences between anisometropic amblyopic and strabismic amblyopic patients, no variations were disclosed in the responses of PVEP and PERG. The abnormal components of the PVEP and PERG in amblyopic subjects possibly reflected a retinal dysfunction in the visual pathway.
