Elektroretinogram förkortas ofta ERG. Förberedelser. Inför en ERG-undersökning får du ögondroppar som förstorar pupillen. Det är för att hela näthinnan ska kunna ses genom ERG-apparaten. Ibland kan man också få ögondroppar som bedövar ögat. Pupillvidgande ögondroppar
An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes. These cells are known as rods and cones. They. Ögonundersökning optiker
Med hjälp av ett elektroretinogram (ERG) utreds den elektriska aktiviteten i ögats näthinna. Vid en ERG-undersökning mäter man den elektriska potentialen som en ljusstimulans får till stånd i näthinnans receptorer. Responsen i stav- och tappcellerna registreras separat.
