The magnification of the Zeiss type of fundus camera depends, except for the case of emmetropy, on the camera‐to‐eye distance. Its relative variation is equal to the product of the patient's ametropia and the difference in the camera‐to‐eye distance. Moreover, magnification is also affected by changing the diopter range scales on the camera.
