fundus camera

camera, fundus 

A camera attached to an indirect ophthalmoscope aimed at photographing the image of the fundus of the eye. This image is produced by the objective of the ophthalmoscope at the first focal point of the objective of the viewing microscope (and of the camera), which forms an image on the film. A flip mirror within the optical path of the viewing microscope allows the observer to view the image of the fundus and focus it, thus ensuring that the image being photographed is as clear as that being viewed. Fundus cameras usually require a dilated pupil of about 4 mm and their fields of view extend up to 45º. They provide an objective photographic record of any condition in the fundus. They can also be used to take photographs of the anterior segment of the eye. See ocular fundus; indirect ophthalmoscope; scanning laser ophthalmoscope.
