Earlier representations of slit lamp findings by professional illustrators primarily pursued didactic purposes. Today, the practicing ophthalmologist primarily captures findings in images in order to be able to compare them later over time. This was systematically and exemplarily worked out impressively recently in the records of Arthur Gloor, an ophthalmologist who practiced in the first half of the twentieth century in the environment of the slit lamp pioneer Alfred Vogt. Vogt, Gloor, and the author of this atlas are united over a century by the idea of capturing what is seen in an image—each, of course, with the means of his environment and his time. However, a new field of application for image documentation in ophthalmic practice has been added: The patient’s own findings can be explained directly on the image. Of course, this only makes sense with significant changes, although this is a very flexible category in everyday life.
