Book Synopsis Diagnosis of Primary Open Angle Glaucoma by : R.N. Weinreb
Download or read book Diagnosis of Primary Open Angle Glaucoma written by R.N. Weinreb and published by Kugler Publications. This book was released on 2017-05-10 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary Open-Angle Glaucoma was the topic of the tenth World Glaucoma Association Consensus meeting. As with prior meetings, it was a daunting task to seek and obtain consensus on broad subject matter that ranges from diagnosis, risk profiling and screening of the disease. As it is unclear how each of us decides how we practice and the evidence to guide us often is sparse, this consensus, as well as the others, is based not only on the published literature, but also on expert opinion. Although consensus does not replace and is not a surrogate for scientific investigation, it does provide considerable value, especially when the desired evidence is lacking. The goal of this consensus is to provide a foundation for diagnosing and managing primary open-angle glaucoma and how it can be best done in clinical practice. Identification of those areas for which we have little evidence and, therefore, the need for additional research always is a high priority. We hope that this consensus report will serve as a benchmark of our understanding. However, this consensus report is intended to be fluid. It is expected that it will be revised and improved with the emergence of new evidence.

Book Synopsis Structure and Function in Early Glaucoma by : Carmen Balian
Download or read book Structure and Function in Early Glaucoma written by Carmen Balian and published by . This book was released on 2016 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glaucoma is a general term that includes an array of ocular conditions that cause a specific neuropathy of the optic nerve (Greenfield, Bagga, et al. 2003) of which abnormalities associated with this disorder are localized at the level of the retinal ganglion cell layer (Epstein 1997; Quigley & Broman 2006). This structure-function relationship is not clear as it relies on several factors such as variability from the structural and functional tests, differences in measurement scales between the two modalities (Greaney et al. 2002; Katz 1999; Drance 1985; Hood et al. 2007) and physiological variation amongst individuals (Pan & Swanson 2006). The global aim of this thesis was to relate visual function of the retinal ganglion cells to structure of the optic nerve head and retinal nerve fiber layer with respect to the following perimetry techniques: i) standard automated perimetry (SAP), ii) frequency doubling technology (FDT), iii) flicker defined form (FDF), and iv) the motion detection test (MDT), and the following imaging instruments: i) confocal scanning laser ophthalmoscopy (HRT), ii) optical coherence tomography (OCT), and iii) scanning laser polarimetry (GDx VCC). The specific purpose of this study was to i) compare the test-retest characteristics of the perimetry techniques, ii) determine which may be more sensitive for early detection, iii) evaluate the structure-function relationship between measures of retinal nerve fiber layer and visual function, and iv) perform a preliminary study to determine which techniques may be most suitable to monitor progression, in patients with early stage glaucoma. MDT showed little change in the 1-year follow-up study thus being unsuitable for monitoring change. FDT and FDF gave a similar performance and are likely optimal for the detection of early functional damage. Poor diagnostic agreement was seen between the HRT and each perimetry technique. Because no one perimetry test showed both high sensitivity and high specificity, it is recommended that a combination of FDF with either SAP, FDT or MDT be used as the functional component in the diagnosis and follow-up of patients with glaucoma. The strongest global structure-function correlations for OCT were seen with SAP, FDT and MDT; for GDx, the strongest association was seen with FDF. These results suggest that FDF and GDx used in combination are best to detect early glaucomatous changes.

Book Synopsis Primary Open Angle Glaucoma, Structure and Function by : Mohamed Mahdy
Download or read book Primary Open Angle Glaucoma, Structure and Function written by Mohamed Mahdy and published by LAP Lambert Academic Publishing. This book was released on 2011-10 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary open angle glaucoma is the second and leading cause for visual damage worldwide. What is lost because of glaucomatous damage cannot be restored by any mean. Its early detection is the most important factor in prevention of such a damage. The current book will highlight the different aspect of glaucomatous damage including; functional visual field damage, morphological optic nerve head and retinal nerve fiber layer damage and changes of the blood flow in the optic nerve head and retinal nerve fiber layer in definite and suspected glaucoma patients and ocular hypertensives as well. The relationship between different modalities of visual field testing (SAP, SWAP and FDT) will be described, in addition standard photography and OCT changes will be compared for the ability to detect early glaucoma. Blood flow changes at the optic nerve head will be compared in both POAG, OHT and glaucoma suspects. The book will clarify which aspect of glaucomatous damage precede the other in different stages of glaucoma and whether is it necessary to test the different aspects of glaucoma damage in order to reach a definite diagnosis.

Book Synopsis Childhood Glaucoma by : R.N. Weinreb
Download or read book Childhood Glaucoma written by R.N. Weinreb and published by Kugler Publications. This book was released on 2013-11-07 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Childhood is the topic of the ninth World Glaucoma Association Consensus. There has been only sparse attention to the diagnosis and treatment of childhood glaucoma. Both pediatric ophthalmologists and glaucoma specialists provide care for such children. In some instances, they manage these individuals alone and, in others, the management is shared. For this consensus, the participation of both groups was solicited. The global faculty, consisting of leading authorities on the clinical and scientific aspects of childhood glaucoma, met in Vancouver on July 16, 2013, just prior to the World Glaucoma Congress, to discuss the reports and refine the consensus statements. As with prior meetings, it was a daunting task to seek and obtain consensus on such a complicated and nuanced subject. It is unclear how each of us decides how we practice, and evidence to guide us often is sparse. It is remarkable how few high level studies have been conducted on the management of childhood glaucoma. Hence, this consensus, as with the others, is based not only on the published literature, but also on expert opinion. Although consensus does not replace and is not a surrogate for scientific investigation, it does provide considerable value, especially when the desired evidence is lacking. The goal of this consensus was to provide a foundation for diagnosing and treating childhood glaucoma and how it can be best done in clinical practice. Identification of those areas for which we have little evidence and, therefore, the need for additional research also was a high priority. We hope that this consensus report will serve as a benchmark of our understanding. However, this consensus report, as with each of the others, is intended to be just a beginning. It is expected that it will be revised and improved with the emergence of new evidence. Robert N. Weinreb, Chair

Available in PDF, EPUB and Kindle. Book excerpt: Introduction We mark the eighth consecutive year for the World Glaucoma Association Glaucoma Consensus with Consensus VIII. Our topic is the Progression of Glaucoma. Global experts were invited and assembled by our international co-Chairs beginning in January 2011, to participate in the Project Forum E-Room, a unique online opportunity to facilitate discussion of each of the consensus meetings. Participants then were engaged in the discussion of five topical areas to reach consensus on key issues that surround and permeate all aspects of the progression of glaucoma. The results of these thoughtful discussions then were summarized by each of the sections with preliminary consensus statements. The Draft of the Consensus Report, including the preliminary consensus statements, was distributed to the Societies and Partners for review and comments prior to the Consensus Meeting that took place in Paris on Tuesday, June 28, 2011. On this day, relevant stakeholders engaged in a stimulating, educational, and thought-provoking session that highlighted the review and revision of the consensus statements. The Consensus Report then was finalized by Consensus co- Chairs and Editors. Consensus statements were reviewed and finalized by the expert Consensus Panel. Robert N. Weinreb, Editor
