Download or read book Ultrasound Biomicroscopy of the Eye written by Charles J. Pavlin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of the use of ultrasound in medicine has been one of evolution of technology and innovative methods of applying this technology to imaging body structures. Many scientists and clinicians have contributed to this evolution. Ophthalmic ultrasound has become an indispensible tool in ophthalmic practice, with its own instrumentation and techniques. Ultrasound frequencies used in ophthalmology have generally been higher than those used in general medicine because of a requirement for higher resolution and a lesser need for deep penetration. Most ophthalmic diagnostic equipment uses frequencies in the 10 MHz range. The use of ultrasound frequencies in the 50-100 MHz range is a relatively new development in ultrasound imaging of the eye. This technique has been developed in our laboratories over the past several years. We have progressed from the theoretical description of the basic science required, past the first in-vitro experiments in eye bank eyes, to the construction of an instrument capable of clinical application. We have gained broad clinical experience with this instrument in normal patients and patients with ocular disease. A commercial instrument based on our original clinical scanner has recently become available, allowing other clinicians to apply this tool to ophthalmic research and clinical practice. We have applied the term ultrasound biomicroscopy to this new imaging technique because of similarities to optical biomicroscopy, i. e. , the observation of living tissue at microscopic resolution.

Download or read book Vascular Considerations in Glaucoma written by S. Fabián Lerner and published by Kugler Publications. This book was released on 2013-03-28 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Open angle glaucoma (OAG) is one of the leading causes of impaired vision worldwide. The pathogenesis of glaucomatous optic neuropathy remains poorly understood, and several pathogenic mechanisms are proposed to coexist. As the world population ages, OAG will become more prevalent and advances in the diagnosis and treatment of glaucomatous optic neuropathy are important to protect and improve the quality of life of our aging population. Treatment of OAG has been directed at lowering intraocular pressure (IOP) which is the only current therapeutic strategy available to patients with glaucoma. While a wide variety of studies have demonstrated that lowering IOP decreases the risk of glaucoma development and/or progression, many studies have also shown that some patients continue to lose vision despite significant lowering of IOP. There have been many attempts to elucidate the etiology for the deterioration in glaucomatous optic neuropathy despite low levels of IOP. Over the past several decades, deficits in the ocular circulation of patients with OAG have become well established and these may explain the continued progression of OAG patients despite lowered IOP. The purpose of the present publication is to provide an updated view of ocular blood flow and vascular dysregulation in OAG. The importance of the topic was demonstrated by the focus of the 2009 6th Consensus meeting of the World Glaucoma Association which focused entirely on blood flow deficits in patients with OAG. Although a great deal of knowledge on vascular risk factors in glaucoma has already been established, many questions remain. Do ocular blood flow deficits precede glaucoma progression? How does ocular perfusion pressure fit into the IOP and blood flow paradigm? What conclusions can be drawn from recent evidence showing the fluctuation of OAG risk factors including IOP, blood pressure and ocular perfusion pressure? We hope this update d current prospective will serve as a foundation for future investigations which will be designed to answer these and other important considerations in the management of glaucoma.

Download or read book Echography in Ocular Pathology written by Pedro Romero-Aroca and published by Bentham Science Publishers. This book was released on 2015-03-30 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph expands on the ultrasound exploration of the ocular globe (or, in other words, the human eye) with a review of the current knowledge about ocular ultrasound techniques and its indications in ophthalmic pathology. Ocular echography has only been recently studied in greater detail by ophthalmologists thanks to new imaging techniques such as optical coherence tomography [OCT] and scanning lasers, which have become the preference in ocular exploration, relegating ultrasound to cases with poor fundus visualization. New ultrasound equipment with multi-frequency linear probes between 15 to 18 MHz, also permits technicians to observe ocular structures with greater detail. A key aspect of ultrasound is its dynamic capability, which allows assessing the displacement of intraocular structures and their relation to the different eye layers. This is crucial in diagnosing retina pathologies that can affect the outcome of cataract surgery. Ocular echography is also an excellent option to determine retinal lesions in cases of ocular tumors (choroid melanoma) as it is also a differential diagnosis for other tumors (metastasic tumors or hemangiomas). The book also includes a chapter on the use of Color-Doppler ocular examinations in the diagnosis of ocular vasculopathies (arterial or venous occlusions). Echography in Ocular Pathology empowers readers – ophthalmologists and clinical technicians – with the knowledge to diagnose different eye pathologies and thus ameliorate ophthalmic patient management.
