Available in PDF, EPUB and Kindle. Book excerpt: The book provides a detailed description in color format of the optic nerve head changes that occur in glaucoma. It explains the normal and variant anatomy of an optic nerve head and why certain discs are more or less likely to develop glaucomatous changes. This book attempts to explain the anatomical basis of common and not so common signs seen in optic nerve head and retinal nerve fibre layer as captured by a digital fundus imaging system and optical coherence tomography. It also includes optic nerve head conditions mimicking glaucoma. The book is relevant for practicing ophthalmologists, vision science researchers, clinical optometrists, postgraduate residents in ophthalmology, sub-specialty fellows as well as general ophthalmologists, neurologists and neurosurgeons.

Available in PDF, EPUB and Kindle. Book excerpt: "No attainment is ever final" Vascular disorders of the optic disc and nerve are important not only to the ophthalmologist but also to the neurologist and the internist. To the first specialty group they represent one cause of blindness or severe visual impairment; to the second group the optic disc edema and optic atrophy seen in these disorders can pose serious problems of diagnosis, or give indica tions of the involvement of the cerebral circulation; while to the last group they are frequently indicative of systemic disease, particularly of the cardiovas cular system. Recent advances in our knowledge of the blood supply of the optic nerve head have shed a significant new light on the subject. With the recent advent of fluorescein fundus angiography, an extra dimension has been added to the study of the ocular and optic disc circulations, and we have entered into a new era in the understanding of ocular vascular disorders "in vivo". In the pre-angiography era, postmortem injection studies, although very valuable, did not completely reveal the vascular pattern of the optic disc in the living, in health, and disease. The ophthalmoscope, without doubt, has been valuable in assessing optic disc lesions, but could not give us informa tion on the circulation of the eye and optic disc "in vivo".

Download or read book Optic Nerve written by Felicia M. Ferreri and published by BoD – Books on Demand. This book was released on 2019-02-13 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The optic nerve is a primary reference for those ophthalmologists and researchers interested in its anatomy and physiology, in the most recent diagnostic techniques, as well as in the clinical management of optic nerve disorders. The book provides a detailed description of the structure and functioning of the optic nerve and attempts at clarifying how anomalies in its development are related with tumor development. The book surveys the most recent diagnostic techniques, such as spectral domain optical coherence tomography, and highlights how these techniques can be employed to evaluate optic nerve layers as well as lesions compressing the visual pathway. Practical references to optic nerve drusen and the changes in the optic nerve due to diabetic retinopathy are also presented. The book is written in a concise fashion and aims at being a major reference to a broad audience, including students, ophthalmologist consultants, neurologists, researchers, and surgeons concerned with optic nerve diseases.

Download or read book Myopia and Glaucoma written by Kazuhisa Sugiyama and published by Springer. This book was released on 2015-10-26 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as an introductory reference on clinical aspects of glaucoma and myopia, providing essential guidelines for diagnosis and monitoring of glaucoma progression in patients, especially those with high myopias. Many clinical studies are presented by leading experts in the field in an accessible style, making the content suitable not only for ophthalmologists but also for optometrists and certified orthoptists as well as for students. The relation between myopia and glaucoma has been the subject of many clinical trials and population-based studies. Most of the data has suggested that moderate to high myopia is associated with increased risk of primary open-angle glaucoma, normal tension glaucoma, and ocular hypertension. There are several factors involved in the diagnosis of glaucoma, but it is often difficult to determine the presence of glaucoma in myopic eyes. A myopic eye, especially in cases of moderate to high myopia, tends to have a thin retina and choroid and to appear thinner than normal. Even with new imaging technologies with improved sensitivity and specificity for detecting glaucoma, each technology presents some challenges when assessing myopic eyes. This book furnishes an overview of these diagnostic challenges with reference to the growing prevalence and severity of myopia in various parts of the world, providing many valuable hands-on reports and clinical studies by authoritative authors. This knowledge will help to do away with the vague area between high myopia and glaucoma faced by clinicians.

Download or read book The Human Eye in Health and Disease written by C. Bader and published by Forgotten Books. This book was released on 2018-08-17 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Human Eye in Health and Disease: As Seen With the Ophthalmoscope In persons with dark irides, the difference in the reflection from the pupil is still more striking, on account of the con trast of colour between the Optic disc and the tunics. Having thus obtained the reflection peculiar to the Optic disc, we place the convex lens (holding it between the fore finger and thumb of the left hand) before the eye under ex amination. The diffused image of the flame, which is thrown into the eye by the Ophthalmoscope, serves to illuminate those parts of the interior of the eye which lie within the area of that image. The rays of light which are reflected, eg. From the Optic disc thus illuminated, have to pass through the lens held in front of the patient's eye, and an inverted defined image of the Optic disc, &c., is formed in front of the lens, i.e. Between it and the observer, and is viewed by him.
