A condition of “dark adaptation” that is used in retinal testing such as the electroretinogram. Dark adaptation is accomplished by placing black goggles over the patient’s eyes for a predetermined period of time (usually about 30 minutes). This can be useful for determining health of “rods,” or the dim light-detecting cells in the retina.
