Ebook: Low Vision: Principles and Applications Proceedings of the International Symposium on Low Vision, University of Waterloo, June 25–27, 1986

An International Symposium on Low Vision was sponsored by the Centre for Sight Enhancement of the School of Optometry, University of Waterloo in June 1986, bringing low vision researchers and clinicians together from a number of countries. The unique feature of the conference is the multi-disciplinary approach towards low vision care. A total of 44 papers were presented in the three day period by speakers of note from the fields of optometry, ophthalmology, psychophysics, special education, nursing and vision rehabilitation. The papers deal with issues in diagnostic science, low vision assessment and rehabilitation. The proceedings volume is ideal for clinicians and vision scientists to update their understanding of low vision research and clinical practice.
