title: [Electroretinographic problems in the diagnosis of diseases of the cones and macula].
abstract: From series of clinical cases, the authors expose how ERG is an essential element for the diagnosis of cone dysfunction with or without macular involvement. They show that to obtain an accurate diagnosis, precise proceedings must be chosen, using stimulation technics correctly selected. They study the advantage of focal or wide stimulations, of the level of the intensity of the stimulation and of the different colored filters. They propose a proceeding for adults examination. For young children, they discuss the advantages and limits of a particular proceeding.
