Par Panel on Passenger Screening. 1996
This book addresses new technologies being considered by the Federal Aviation Administration (FAA) for screening airport passengers for concealed weapons…
and explosives. The FAA is supporting the development of promising new technologies that can reveal the presence not only of metal-based weapons as with current screening technologies, but also detect plastic explosives and other non-metallic threat materials and objects, and is concerned that these new technologies may not be appropriate for use in airports for other than technical reasons. This book presents discussion of the health, legal, and public acceptance issues that are likely to be raised regarding implementation of improvements in the current electromagnetic screening technologies, implementation of screening systems that detect traces of explosive materials on passengers, and implementation of systems that generate images of passengers beneath their clothes for analysis by human screeners.Microgravity and Vision Impairments in Astronauts
Par Erik Seedhouse. 2015
Recent missions on board the International Space Station have revealed previously unreported physiological consequences of long duration space flight, particularly…
in eyesight, and in this Brief Dr. Seedhouse reviews the existing theories on what causes this degeneration and how long it will last. Notably, 60% of long-duration crews have reported subjective degradation in vision, a clear indication that further study is necessary before astronauts embark on even longer-term space missions. Decreased near-visual acuity was reported in 46% of ISS/Mir crewmembers, resulting in a change of up to 2 dioptres in their refractive correction. It is possible that ophthalmic changes have been present since the first days of spaceflight, but had been attributed to other causes; this approach to the issue as well as other hypotheses are all presented in full to give a broad foundation of the existing knowledge on the topic. The changes have occurred at various times during a mission with varying degrees of visual degradation. Some cases resolved on return to Earth, but several crewmembers have not regained pre-flight visual acuity, indicating the damage may be permanent. One explanation of the syndrome has been attributed to hyperopic shift due to aging, but onboard analysis techniques, including visual acuity assessments, retinal imagery, and ultrasound examination of the eye, has led to the acceptance of a wider syndrome. In addition to vision changes, studies have reported flattening of the globe, swelling of the optic disc (papilledema), choroidal folds in the retina, swelling of the optic nerve sheath, and visual field defects. It is widely hypothesized that this spectrum of symptoms may be explained by an elevation of intracranial pressure (ICP). Establishing the provenance of this medical problem, monitoring its occurrence and resolving the symptoms for future long term space missions is a key challenge for space medicine. With this book, readers have an entry point for understanding the full scope of the problem and its possible origins.Management of Complications in Refractive Surgery

Par Andreas Reichenbach, Andreas Bringmann. 2010
Müller cells may be used in the future for novel therapeutic strategies to protect neurons against apoptosis (for example, somatic…
gene therapy), or to differentiate retinal neurons from Müller/stem cells. Meanwhile, a proper understanding of the gliotic responses of Müller cells in the diseased retina, and of their protective vs. detrimental effects, is essential for the development of efficient therapeutic strategies that use and stimulate the neuron-supportive/-protective - and prevent the destructive - mechanisms of gliosis.Sjögren’s Syndrome

Par Parthopratim Dutta Majumder, J. Fernando Arevalo, Jay Chhablani. 2018
This book explains the underlying rationale for retinal and choroidal imaging in the context of systemic diseases. Various systemic diseases…
involve the eyes, and for some, the eyes could provide the first clue to their presence. Advances in posterior segment imaging have significantly improved our understanding of the pathophysiology and management of posterior segment diseases. However, imaging techniques like enhanced depth imaging, oximetry, adaptive optics, and retinal blood flowmetry have remained largely unexplored in connection with systemic diseases. Enhancing the available literature on the use of such imaging techniques for various systemic diseases, this handbook will help readers understand their pathomechanisms, supporting early diagnosis and more targeted therapeutic approaches. As such, it offers an essential resource for ophthalmologists, especially those with predominantly vitreo-retinal and uvea experience.Plasticity in Sensory Systems

systems. It covers a breadth of recent scientific study within the field including research on healthy systems and diseased models of sensory processing. Topics include visual and visuomotor learning, models of how the brain codes visual information, sensory adaptations in vision and hearing as a result of partial or complete visual loss in childhood, plasticity in the adult visual system, and plasticity across the senses, as well as new techniques in vision recovery, rehabilitation, and sensory substitution of other senses when one sense is lost. This unique edited volume, the fruit of an International Conference on Plastic Vision held at York University, Toronto, will provide students and scientists with an overview of the ongoing research related to sensory plasticity and perspectives on the direction of future work in the field.Binoculars
Par Philip F. Dimeo. 2015
For over 14 years, Philip DiMeo, a talented cartoonist and social worker, led a double life, masquerading as a fully…
sighted person, while becoming blind. What prompted him to hide his condition? Pride, and fear that if his impending blindness were discovered he would lose all that was important. He concealed his vision loss, a secret that he believed could potentially ruin his life, but in hindsight opened doors. At most social functions, fearful that he would trip, bump into someone, or knock something over, his wife propelled him around. Ignoring warnings from his ophthalmologist, he continued driving despite a series of auto accidents which included driving onto railroad tracks while an oncoming train approached. Philip reveals that, despite diagnoses by three ophthalmologists and three optometrists, he denied having retinitis pigmentosa, an inherited degenerative eye disease that causes severe vision impairment and often blindness. When Philip finally confronted his disability, he found that the challenges of his vision loss were the springboard to achievements to come. Binoculars is a sensitive, amazing, and astonishingly revealing first-hand account of a man who achieves incredible feats with his courage and talent, while finally coming to terms with his blindnessGlaucoma Surgery

Par Dominique Raynaud. 2017
This book clarifies the interrelationship between optics, vision and perspective before the Classical Age, examining binocularity in particular. The author…
shows how binocular vision was one of the key juncture points between the three concepts and readers will see how important it is to understand the approach that scholars once took. In the Middle Ages and the Renaissance, the concept of Perspectiva - the Latin word for optics - encompassed many areas of enquiry that had been viewed since antiquity as interconnected, but which afterwards were separated: optics was incorporated into the field of physics (i. e. , physical and geometrical optics), vision came to be regarded as the sum of various psycho-physiological mechanisms involved in the way the eye operates (i. e. , physiological optics and psychology of vision) and the word 'perspective' was reserved for the mathematical representation of the external world (i. e. , linear perspective). The author shows how this division, which emerged as a result of the spread of the sciences in classical Europe, turns out to be an anachronism if we confront certain facts from the immediately preceding periods. It is essential to take into account the way medieval scholars posed the problem - which included all facets of the Latin word perspectiva - when exploring the events of this period. This book will appeal to a broad readership, from philosophers and historians of science, to those working in geometry, optics, ophthalmology and architecture.Retinal and Choroidal Manifestations of Selected Systemic Diseases
