Taschenbuch. Zustand: Neu. Neuware - 'The Stereoscope in Ophthalmology' is a specialized clinical manual detailing the diagnostic and therapeutic applications of the stereoscope in eye care. Written by David W. Wells, this work explores the evolution and practical utility of stereoscopic vision tests and exercises designed to treat visual impairments such as strabismus and heterophoria. The text provides a comprehensive look at the physiological principles of binocular vision and the developmental techniques used to strengthen ocular muscles and improve fusion faculty. Through detailed instructions and clinical observations, Wells outlines various methods for using the phoro-optometer and the stereoscope as primary tools for orthoptic training. The book covers essential topics including the measurement of fusion power, the correction of squints, and the psychological aspects of depth perception. It serves as a significant historical reference for the development of non-surgical interventions in ophthalmology and optometry during the early twentieth century. This work remains a valuable resource for those interested in the history of medical instrumentation and the foundational practices of visual rehabilitation. Its focus on the mechanics of the human eye and the innovative use of early optical technology provides deep insights into the clinical landscape of the era.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
