Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book gives an overview of Retinoscopy, which is a technique developed to measure the refractive error of the eye. Invented by the physician and scientist Herman von Helmholtz in 1851, this technique became more popular in the 1880s after the invention of the electric light bulb. The author, an adjunct professor at the Philadelphia Polyclinic and College for Graduates in Medicine, simplifies the method, making it more accessible for fellow ophthalmologists and students. However, Retinoscopy presents significant advantages over subjective methods of determining refractive errors, including its ability to be performed quickly and easily, with minimal patient participation. The author also discusses in detail the use of the plane and concave mirror, light-screen, and dark-room setup, as well as the significance of the position of the observer, the patient, and the light source. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781334256936_0
