It is surprising that so many manufacturers are still stimulated to improve the quality of fundus pictures by improving the fundus camera design. The general tendency is to achieve a wider angle of view. With the wider field we have a larger area of the fundus in one shot, and we can take fewer pictures for mosaic fundus photographs. There is also a tendency to make better use of the 24 x 36 mm film format. The next step for better wide-angle pictures is a larger format camera. The distortion-free 90 degrees fundus fluorescein angiograms shown by the Canon and the Nikon company are excellent. Although it has the advantage of a wider view, we must not underestimate the great value of more detailed photographs of the fundus! Alcon and the American Optical fundus cameras make dilation almost unnecessary and are portable and easy for fundus photography on location, e.g. patients in bed or anaesthetized. The Alcon indirect ophthalmoscope/camera is especially useful for taking pictures of the extreme fundus periphery in neonates and infants. The permanent availability of two 35-mm cameras on the Topcon fundus camera has the advantage of less mounting/dismounting; this saves times and wear.
