This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition of Radiotherapy of Intraocular and Orbital Tumors in 1993 the treatment programs for cure have changed from the dominance of surgical resection to the utilization of radiation therapy with preservation of the eye intact and preservation of vision. In 2002 about 2,300 primary eye tumors will be diagnosed in the United states, 75% of which will be choroidal melanomas, 20% retinoblastomas, and the remainder a wide variety of tumors - malignant lymphoma, rhabdomyosarcomas, liposarcomas, meningiomas, malignant fibrous histiocytomas, etc. Even so, the majority of malignant tumors of the eye are metastatic, primarily from cancers of the lung or breast. The impact of newer imaging studies, including computed tomography, magnetic resonance imaging, and ultrasound with and without contrast medium, have allowed for better tumor definition, more precise treatment techniques, and major improvement in local control, with preservation of the eye intact and excellent survival. The better histologic definition of the tumor has selected more appropriately the cases suitable for adjuvant chemotherapy particularly demonstrated by the combined integrated multimodal treatment of rhabdomyosarcoma without enucleation. Surgical techniques are now being reserved for biopsy and for treatment failures, a dramatic change in treatment approaches since 1993. The second edition by Sagerman and Alberti clearly demonstrates this major change in treatment. The volume explores the impact of diagnostic workup, the role of surgery, the role of external beam radiation therapy, the use of radioactive plaques, photocoagulation, cryotherapy, and other less major surgical procedures.

Download or read book Transmission of the Ocular Media written by Edward A. Boettner and published by . This book was released on 1962 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Safety with Lasers and Other Optical Sources written by D. H. Sliney and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1042 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly a decade aga a general review article on the evaluation of optical radia tion hazards was published in Applied Optics (Sliney and Freasier, 1973). This arti cle received many favorable comments but also prompted many inquiries regarding specific optical hazard problems. From this it became evident that a monograph rather than a supplemental and expanded article was needed to fill this literature gap relating to laser and optical radiation hazards. The present work is designed to fill that gap, and is structured to permit either classroom or self-study use. Much of the material in this book was developed in eonnection with short courses on laser safety and radiometry in which we have participated, as weIl as from our previous articles. In particular, the sequenee of chapters is based upon the experiences which we have had in lecturing in courses with different schedules. One of the great difficulties in developing a text of this nature is that a broad, multidisciplinary background must be included in order that the reader can comprehend all of the subjeet matter readily. For this reason, the material presented on anatomy and physiology is orien ted toward the engineer or physical scientist, while the review material on basic optical physics is intended more for the physician or life scientist.
Download or read book Modern Ophthalmic Optics written by José Alonso and published by Cambridge University Press. This book was released on 2019-04-11 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive account of the most recent developments in modern ophthalmic optics. It makes use of the powerful matrix formalism to describe curvature and power, providing a unified view of the optical and geometrical properties of lenses. This unified approach is applicable to the design and properties of not only spectacle lenses, but also contact and intraocular lenses (IOL). The newest developments in lens design, manufacturing and testing are discussed, with an emphasis on the description of free-form technology, which has surpassed traditional manufacturing methods and allows digital lenses to be specifically designed with the unique requirements of the user. Other important topics which are covered include modern lens materials, up-to-date lens measuring techniques, contact and intraocular lenses, progressive power lenses, low vision aids, ocular protection and coatings. Providing a broad overview of recent developments in the field, it is ideal for researchers, manufacturers and practitioners involved in ophthalmic optics.
