Book Description
Excerpt from The American Encyclopedia and Dictionary of Ophthalmology In adopting the strictly alphabetical sequence of subject-headings it has been necessary to review for the first volume practically the whole range of the literature of Ophthalmology and its related sciences. It will, as a consequence, easily be understood how difficult it has been to collect and treat with complete satisfaction all the subjects commencing with the first letter of the alphabet, that directly and indirectly relate to the eye and its diseases. However, it is the belief of the Editor and his collaborators that no topic of importance has been neglected. When a heading that quite evidently should have been noticed has been omitted or, more likely, if new topics of interest arise after the publication of the volume to which they belong, alphabetically, they will receive due attention in the appendix. In addition to the attempt to write and edit a comprehensive Encyclopedia of Ophthalmology the Editor has made an effort to combine with it a Dictionary of such English, Latin, French, German and Italian words and phrases as will be most useful to students of ophthalmology in general. This has been a heavy task, beset with many difficulties. In the first place, it is not an easy matter to decide whether a particular word or phrase is of ophthalmic interest, or not. Broadly speaking, the majority of medical and scientific subjects in the languages referred should be interesting and valuable to the educated ophthalmologist but, if most of the words and phrases utilized in general medicine and surgery were so included, the additions would pad this work to an unseemly degree. Even as it is, the inclusion of some of the terms already chosen (although they were all taken from ophthalmic text-books) may give rise to criticism and to the imputation of 0 mere "filling." It will, in this connection, be noticed that the array of German words is much larger than those in other languages. There are several reasons for this. In the first place, the German language occupies co a pre-eminent position in the world of science, and many Englishes speaking ophthalmologists have received a considerable portion of their foreign education in Germany and from Germans. Consequently, the excess of German words naturally represents the largest proportion of foreign literature accessible to the average English reader.

Book Description
When the eyeball is indented in total darkness, within less than 200 mil liseconds an oval or quarter-moon shaped spot of light is perceived in the part of the visual field corresponding to the indented region of the retina. In the seconds following, this phosphene extends across the whole visual field and alters in structure during further eyeball indentation. It is then seen as irregular large bright spots of light, finely structured moving light grains ('light nebula') and stationary bright stars. Regular geometrical patterns appear only when both eyes are indented simultaneously [1]. When the eyeball deformation is released, part of the retina again lights up for another one or two seconds and curved light lines are seen following the course of the larger retinal vessels (Fig. 1). In the following we will review the history of this phenomenon, which played an important role during the first 2200 years of vision theories and in the development of models to explain normal vision. 2. Pre-Socratic philosophers, Plato and Aristotle Alcmaeon of Croton (6-5th century B. C. ), who was a member of the Pythagoraean sect and one of the founders of Greek medicine, was the first to describe mechanical deformation of the eyeball leading to light sensa tions. According to Aristotle's pupil Theophrast of Eresos, Alcmaeon report ed that 'the eye obviously has fire within,for when the eye is struckfireflashes out' [2, p. 88].
