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

Book excerpt: To the best of our knowledge, the 1st Global AIGS Consensus Meeting on ""Structure and Function in the Management of Glaucoma"" was also the first global consensus meeting in ophthalmology. The goal was to reach an evidence-based consensus for both clinical practice and research through the use of information obtained from peer-reviewed literature describing functional and structural diagnostic testing in glaucoma. The faculty and review group consisted of leading global authorities on glaucoma diagnostic testing. The preparation for the Consensus was unique in its format (see page xii). Repor.
Download or read book Glaucoma Imaging written by Antonio Ferreras and published by Springer. This book was released on 2015-10-21 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This atlas offers a truly comprehensive update on the use of imaging technologies for the diagnosis and follow-up of glaucoma. In addition to standard automated perimetry, gonioscopy, fundus photography, and stereophotography, other advanced, high-resolution methods for imaging the eye in glaucoma are explained in detail, including ultrasound biomicroscopy, confocal scanning laser ophthalmoscopy, scanning laser polarimetry, and spectral domain optical coherence tomography. The role of the various tests and the keys to optimizing their use in clinical practice are detailed with the aid of high-quality figures in order to enable the reader to achieve the best possible performance when applying these tools. The risk of developing visual disability and blindness as a consequence of glaucoma varies widely among affected individuals. Personalized testing strategies and tailored therapeutic interventions are required to effectively reduce visual impairment due to glaucoma. Glaucoma Imaging will assist residents, researchers, and clinicians in improving their ability to understand and integrate the information obtained using traditional techniques with the reports provided by computer-assisted image instruments.

Download or read book Optical Coherence Tomography in Glaucoma written by Ahmet Akman and published by Springer. This book was released on 2018-09-17 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the practical aspects of Optical Coherence Tomography (OCT) in glaucoma diagnostics offering important theoretical information along with many original cases. OCT is a non-invasive imaging technique that acquires high-resolution images of the ocular structures. It enables clinicians to detect glaucoma in the early stages and efficiently monitor the disease. Optical Coherence Tomography in Glaucoma features updated information on technical applications of OCT in glaucoma, reviews recently published literature and provides clinical cases based on Cirrus and Spectralis OCT platforms. In addition, newer techniques like event and trend analyses for progression, macular ganglion cell analysis, and OCT angiography are discussed. This book will serve as a reference for ophthalmologists and optometrists worldwide with a special interest in OCT imaging providing essential guidance on the application of OCT in glaucoma.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Purpose: Standard automated perimetry (SAP) is one of the most widely used functional tests in glaucoma management, and as such, it serves as the benchmark for comparison to all other forms of glaucomatous testing. Optical coherence tomography (OCT) is also a commonly used technology in glaucoma management and allows for a quantifiable structural measurement. One of the more relevant OCT-based measurement for glaucoma is the peripapillary retinal nerve fiber layer (RNFL) thickness; however, investigations comparing OCT RNFL thickness measurements to the actual histology measurements of the RNFL have been rather limited, especially pertaining to measurements in the presence of glaucomatous disease. Flicker-defined form perimetry is a new addition to perimetric testing, and its use in glaucoma testing remains largely unexplored. The purpose of this dissertation is to investigate each of these structural and functional measurements of glaucoma as they relate to each other (SAP and OCT, OCT and histology, SAP and FDF) in order to provide a framework for understanding the optimal stage of glaucoma at which each test is valuable. Methods: In experiment 1, SAP and OCT measurements were obtained from healthy and glaucoma participants. Retinal ganglion cell estimates were calculated from the two different regions and matched to corresponding regions to determine agreement. In experiment 2, health and experimental glaucoma eyes from macaque monkeys were measured with OCT RNFL thickness protocols. The retinal tissue was then processed and imaged with confocal microscopy so that histological RNFL thickness measurements could be obtained. Comparison between similar regions were made and examined for agreement in normal and glaucomatous retina. In experiment 3, SAP and FDF measurements were obtained from healthy and individuals with early and moderate glaucomatous visual field loss. The distributions of thresholds were determined and test-retest characteristics of each form of perimetry were compared. Results: The first experiment showed with age-modification alone, RGC estimates derived from SAP and RNFL thickness values were in agreement in subjects with no visual field loss and in subjects with early to moderate glaucomatous visual field loss. Subjects with end-stage glaucomatous field loss demonstrated a systematic discordance between the perimetric and thickness-derived RGC estimates that showed a high correlation to stage of disease. Application of a stage-of-disease factor in the model produced agreement between OCT and SAP-based RGC estimates across the entire spectrum of glaucoma subjects. RNFL thickness reductions were observed in all eyes with experimental glaucoma. The limits of agreement between OCT- and histology-derived thickness measurements were quite large (95% limits of agreement: untreated = -51.17 ℗æm to 35.15 ℗æm and treated eyes -54.50 ℗æm to 43.43 ℗æm). Percent differences between measurements were much larger for the treated group than the untreated group (untreated = 11.18% ℗ł 33.92% and treated = 40.95% ℗ł 83.97%). Percent differences showed the highest differences when RGC counts per confocal segment (1 confocal segment = 225 ℗æm) fell below 20 RGC/segment. The third experiment revealed different zones of visual sensitivity in glaucomatous disease between SAP and FDF perimetry. The distribution of threshold scores was less for FDF (18.53℗ł4.32 dB) when compared to SAP (30.39℗ł2.55), and showed considerably lower thresholds with FDF scores in glaucoma subjects (14.09℗ł6.04 dB) when compared to the SAP scores (28.70℗ł4.78 dB) for this group. Comparison of test-retest threshold scores reveals better repeatability in FDF perimetry than SAP for scores that fall within the middle (95% limits of agreement for SAP = -10.7 to 9.7; FDF = -6.7 to 6.5) and lower (SAP = -10.3 to 16.8 ; FDF = -8.7 to 7.9) threshold ranges for each instrument. Conclusions: Significant correlations between individuals with no glaucomatous disease and early to moderate glaucomatous disease suggest that the model is applicable to estimating ganglion cell populations from both SAP visual sensitivity values and OCT derived ganglion cell populations. Discordance between the estimates in the later stage of glaucomatous disease suggests that an additional change in the composition of the RNFL or a limitation in the measurement of the RNFL thickness may falsely inflate RGC estimates in this model. Agreement between OCT measurements of the peripapillary RNFL and histological measurements showed substantial variation. The greatest differences in measurements occurred in non-temporal segments when RGC counts fell below a critical value in eyes with glaucoma. Flicker-defined form and standard automated perimetry differ in the range of visual sensitivities that each instrument is able to measure, with FDF perimetry showing overall less sensitivity to both normal and glaucoma participants. Clinically, test-retest repeatability is improved for FDF when compared to SAP with threshold sensitivity observed in the lower- to mid- loss ranges, however this may be a product of the differences in the stimulus properties, testing strategy, dynamic range and of the each instrument, differences in the measurement scale, or a combination of one or more of these factors.

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

Book excerpt: This text provides a practical and expert problem-solving approach to the diagnosis and management of the glaucoma patient. The authors place emphasis on an approach to chronic, year-in, year-out care of the glaucoma patient - one of the most challenging management issues of the general ophthalmologists' practice. The first section of the book reviews the differential diagnosis of the patients who present with signs and symptoms suggestive of glaucoma, such as elevated pressure, abnormal optic nerve head, abnormal visual field and abnormal anterior chamber angle. The second section focuses on the chronic management of glaucoma. The authors describe the thought process/clinical decisions used to formulate and monitor treatment. In particular, they describe: how to determine the vigour with which to treat and monitor the individual patient; and how to determine if treatment is adequate and/or successful.
