THE PERIMETER OR CAMPIMETER. This instrument is for the purpose of mapping out the visual or retinal field. The essential principle is the same in every make of instrument. While the patient fixes a central fixation point, a small test-object is moved either from the periphery of an arc toward this central point or from the central point toward the periphery. The place where the test object, being thus moved, comes into the patient's indirect vision, or passes out of vision, marks the limit of the retinal field in that meridian. The test is repeated in every meridian, successively, thus giving a contour of the retinal field. The chief differences between campimeters is that, whereas the older forms are monocular, the later models are binocular or stereoscopic. Standard Registering Perimeter. f. Put the chart in place in the chart-holder behind the metal arc. 2. Seat the patient comfortably before the instrument so that his chin rests easily on the chin rest. Instruct him to fix the central fixation mark on the target. Blank the left eye. 3. Explore the visual field by moving the test object (fitted on to the long handle) from the center of the target out along the metal arc toward the periphery until the patient, who continues to fix the center, can no longer see the object. When this point is reached, indicate it on the chart by punching it through the perforation in the metal arc. 4. Revolve the metal arc to each meridian, successively, and repeat the test in each meridian. 5. When all meridians have been thus tested and marked, take out the chart and join up, with a pencil or pen, the punch marks in the chart. The result will show the visual field. 6. Repeat the process for the left eye. The Stereo-Campimeter. By means of...

Available in PDF, EPUB and Kindle. Book excerpt: Retinoscopy is an eye exam that determines the refractive error of the eye (long sighted, short sighted, astigmatism). A refraction test indicates the strength of the prescription needed for glasses or contact lenses. The new edition of this book provides a concise overview of clinical refraction. Presented in an easy to read format, it is divided into two main sections. The first part explains basic clinical procedures for routine refraction, beginning with an introduction to instruments and the procedure, followed by aspects of the test for different disorders including myopia (short sightedness), astigmatism, keratoconus and refraction in children. Section two provides in depth discussion on retinoscopy and correct use of the retinoscope. The second edition has been fully revised and updated to explain the latest advances in the field, and is further enhanced by clinical images and figures. Key points Practical guide to clinical refraction and retinoscopy Fully revised and updated second edition Explains basic procedures and instruments for refraction test and refraction in different ophthalmic disorders Previous edition (9789351520634) published in 2014
