A motion picture technique has been developed for recording on color film the magnified direct image of the ocular fundus and the anterior chamber angle. This method employs the Zeiss operating microscope, a motion picture camera specifically designed for use with this instrument, a special power supply which permits high intensity illumination and a corneal contact lens. With this equipment, faithful color reproduction of a clear image is possible at high frame speeds.
The applications of motion picture photography of the inner eye are manifold. Recording of intraocular vessel pulsations,1 observation of the end point of ophthalmodynamometry, and appraisal of retinal coagulation,2 are only a few of the practical uses of this type of photography in research and teaching.3 However, methods previously utilized for motion picture photography of the inner eye have generally had distinct limitations. Usually, the patient had to be photographed in the erect position,
