The desire to record on motion picture film the fundus image as seen when using indirect ophthalmoscopy has resulted in the apparatus here described. During the three years that this method of photography has been used in the Retina Service of the Massachusetts Eye and Ear Infirmary and the offices of the Retina Associates, it has proved to be of value in recording those changes of the posterior segment which could not be adequately photographed by the usual means. Lesions of considerable elevation can be recorded on film almost as clearly as they can be visualized by using modern indirect ophthalmoscopy, and this demonstrates the great depth of focus inherent to this system of photography (Fig 1). Areas anterior to the equator can be cinematographed by using scleral indentation and the dynamics of scleral palpation are clearly visible in the film.
