This book examines the contrast sensitivity of the human visual system - concerning the eye's ability to distinguish objects from each other or from the background - and its effects on the imageforming process. The text provides equations for determining various aspects of contrast sensitivity, in addition to models that easily can be used for practical applications.
Visual Fields: Examination and Interpretation, 3rd edition contains revisions and updates of earlier material as well as a discussion of newer techniques for assessing visual field disorders. The book begins with a short history of the field of perimetry and goes on to present basic clinical aspects of examination and diagnosis of visual field defects in the optic nerve, optic disc, chorioretina, optic chiasm, optic tract, lateral geniculate field bodies, and the calcarine complex. Additional aspects of visual field examination are explored including those of monocular, binocular, and junctional field defects, congruity vs. incongruity, macular sparing vs. macular splitting, density, wedge-shaped homonymous field loss, and monocular temporal crescent. Various new techniques of automated perimetry are also considered including SITA, FASTPAC, and SWAP. This volume provides a very useful overview of the techniques of visual field examination in a number of eye disorders and will be of interest to all ophthalmologists, neuro-opthalmologists, retina specialists, and optometrists.
Optical Devices in Ophthalmology and Optometry Medical technology is a fast growing field. Optical Devices in Ophthalmology and Optometry gives a comprehensive review of modern optical technologies in ophthalmology and optometry alongside their clinical deployment. It bridges the technology and clinical domains and will be suitable in both technical and clinical environments. The book introduces and develops basic physical methods (in optics, photonics, and metrology) and their applications in the design of optical systems for use in ophthalmic medical technology. Medical applications described in detail demonstrate the advantage of utilizing optical-photonic methods. Exercises and solutions for each chapter help understand and apply basic principles and methods.
