Book excerpt: Excerpt from Manual and Atlas of Medical Ophthalmoscopy The ophthalmoscope is of use to the physician because it gives information, often not otherwise obtainable, regarding the existence or nature of disease elsewhere than in the eye. This information depends upon the circumstance that we have under observation - 1. The termination of an artery and the commencement of a vein, with the blood circulating in each. 2. The termination of a nerve, which, from its close proximity to the brain, and from other circumstances, undergoes significant changes in various diseases of the brain, and in affections of other parts of the nervous system. 3. A nervous structure - the retina, and a vascular structure - the choroid - which also suffer in a peculiar way in many general diseases. For the efficient use of the ophthalmoscope in medical practice, the student must be familiar with the use of the instrument; he must also be familiar with the normal fundus oculi, with the changes in its appearance (congenital and other) that are of no clinical significance, and also with those that are ocular in origin, such as posterior staphyloma, glaucomatous excavation, and the like. An acquaintance with these must be gained from the ophthalmic surgeon before inferences can safely be drawn regarding the significance of other alterations met with in various diseases. The following pages assume the possession of a general knowledge of the use of the instrument, but a few words regarding some points which are of special importance may be of service. A first requisite in medical ophthalmoscopy is familiarity with the direct method of examination. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
