Book Description
Blindness or serious vision impairment is one of the most feared disabilities known to humankind. A 2016 report compiled by the National Eye Institute (NEI) of the National Institutes of Health (NIH) and Prevent Blindness America states that although half of all blindness can be prevented, the number of people who suffer vision loss continues to increase. The technique of dynamic light scattering (DLS) was developed by physicists in the late 1960s to early 1970s. DLS is now emerging as a potential ophthalmic tool, making possible studies of virtually every tissue and fluid comprising the eye, thus pushing the envelope for broader applications in ophthalmology. This book presents a comprehensive review of the application of light scattering in clinical use. It is the first of its kind, offering insight to how DLS can be applied to the human eye as well as animals. Chapters discuss DLS in neurological diseases, including protocols, informed consent, and patents. Dynamic Light Scattering Spectroscopy of the Human Eye is a must-have resource for physicians, engineers, and physicists interested in the clinical application of DLS to diagnose and potentially treat medical conditions in a non-invasive, quantitative and novel way.

Book Description
This open access book provides a comprehensive overview of the application of the newest laser and microscope/ophthalmoscope technology in the field of high resolution imaging in microscopy and ophthalmology. Starting by describing High-Resolution 3D Light Microscopy with STED and RESOLFT, the book goes on to cover retinal and anterior segment imaging and image-guided treatment and also discusses the development of adaptive optics in vision science and ophthalmology. Using an interdisciplinary approach, the reader will learn about the latest developments and most up to date technology in the field and how these translate to a medical setting. High Resolution Imaging in Microscopy and Ophthalmology – New Frontiers in Biomedical Optics has been written by leading experts in the field and offers insights on engineering, biology, and medicine, thus being a valuable addition for scientists, engineers, and clinicians with technical and medical interest who would like to understand the equipment, the applications and the medical/biological background. Lastly, this book is dedicated to the memory of Dr. Gerhard Zinser, co-founder of Heidelberg Engineering GmbH, a scientist, a husband, a brother, a colleague, and a friend.

Book Description
This book covers advances made since the 2004 Springer volume “Polarized Light in Animal Vision” edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopies; normal and anomalous polarization patterns of the skies; skylight polarization transmitted through Snell’s window and both linearly and circularly polarized signals produced by terrestrial and aquatic animals. This Part also examines polarized “light pollution” induced by anthropogenic factors such as reflection off asphalt surfaces, glass panes, car bodies, and other man-made structures that are now known to form ecological traps for polarotactic insects. Part III surveys some of the practical applications of polarization vision including polarization-based traps for biting insects, ground-based polarimetric cloud detectors and an historical examination of the navigational abilities of Viking seafarers using the sky polarization compass. The deterrent qualities of ungulate pelage to polarization-sensitive biting insects is also examined in this section.

Book Description
Noninvasive Diagnostic Techniques in Ophthalmology explores the special noninvasive tools developed to function as diagnostic indicators and to further our understanding of ocular function. The volume's focus is on new development in instrumentation and techniques for studying the cornea, lens, retina, vitreous, and aqueous dynamics; whereby special attention is given to how each technique has improved our understanding of basic processes and diagnostic capability. Theoretical aspects, possible sources of error, current problems and limitations, safety evaluation, and future applications and directions are considered. Topics examined include ophthalmic image processing; magnetic resonance imaging of the eye and orbit; diagnostic ocular ultrasound; corneal topography; holographic contour analysis of the cornea; wide field and color specular microscopy; use of the Fourier transform method for statistical evaluation of corneal endothelial morphology; confocal microscopy; in vivo corneal redox fluorometry; evaluation of cataract function with the Scheimp-flug camera; fluorescence and Raman spectroscopy of the crystallin lens; in vivo uses of quasi-elastic light scattering; fundus reflectometry; and clinical visual psychophysics measurements. The book offers discussions of fractal analysis of human retinal blood vessel patterns, scanning laser tomography of the living human eye, fundus imaging and diagnostic screening for public health, and digital image processing for ophthalmology, as well as a detailed appendix comprising additional topics and sources.

Book Description
The spectral transmittance of ultraviolet, visible, and near infrared light through the ocular media of humans has been measured. Using freshly enucleated eyes, the transmittances of each component part (cornea, aqueous humor, lens, vitreous humor) were determined for the wavelength range from 0.22 to 2.8 microns. To date 9 eyes have been measured, ranging in age from 4 weeks to 75 years. Two types of measurements were made: the first to measure the total light transmitted (direct and scattered) at each wavelength and the second to measure the percent transmittance of that light passing directly through the various media without absorption or scattering. The results show that: (a) the transmission of ultraviolet radiation decreases with the age of the eye; (b) the transmission of infrared radiation appears to be independent of the age; and (c) the maximum total transmittance of the whole eye, about 81 percent, is obtained in the region from 600 to 850 millimicrons.
