Electrodo de lente de contacto en el ojo

La electroretinografía (ERG) es un examen que mide la actividad eléctrica de la retina ante la luz. Se realiza colocando un electrodo en la córnea del ojo después de que ésta ha sido anestesiada. Con este examen se pueden evaluar trastornos de la retina, tanto hereditarios como adquiridos. También es útil para determinar si es recomendable practicar una cirugía de retina.Electrodo de lente de contacto en el ojo
