Available in PDF, EPUB and Kindle. Book excerpt: Pathologic Myopia is a major cause of severe vision loss worldwide. The mechanisms for vision loss include cataract, glaucoma, retinal detachment, and above all, myopic maculopathy within the posterior staphyloma. The first edition of Pathologic Myopia is one of the only current books to specifically address this disease and discusses recent developments in imaging technologies and various approaches to treatments, such as laser photocoagulation, photodynamic therapy, pharmaco-therapeutic injections in the vitreous, and surgery. This new edition is a timely update to the standard reference in the field, with new chapters on advanced refractive error correction, genetics, developing a classification system, and special surgical approaches for pathologic myopia. Complete with even more high-quality color images and informative tables, this book is written and edited by leaders in the field and is geared towards ophthalmologists, including residents and fellows in training, glaucoma and cataract specialists, and vitreoretinal macula experts.
Download or read book The Repeatability of Peripheral Axial Length Measurements written by Andrew G. Noble and published by . This book was released on 2012 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research has focused on methods to stymie eye growth by inducing peripheral myopic defocus. It is therefore important to determine whether any change in peripheral eye length is greater than that which can be expected by measurement error alone. This study aims to determine the inter-occasion repeatability of peripheral axial length measurements using the IOLMaster in order to learn more about the growth of peripheral eye.
