Application of a new Scheimpflug camera (EAS-1000) to animal cataract models

A newly developed anterior eye segment system, EAS-1000, was applied to animal experiments. Since the device was developed to be used with human eyes, several minor changes were made to facilitate the use with animals. These changes included an animal-holding place instead of a chin rest, an additional monitor screen for help in alignment, a foot pedal for flushing and image cancellation and variable illumination for adjusting the volume of the retroillumination image. The examined animals were mice, rats, rabbits, dogs and monkeys. The image quality of this camera was almost always satisfactory. One advantage of this device is that the quality of the images can be checked instantly, making it possible to store only images of superior quality. The mean of the repeatability test had a coefficient of variation of 6%.
