Biophysical Properties in Glaucoma: Diagnostic Technologies: summary, description and annotation

We offer to read an annotation, description, summary or preface (depends on what the author of the book "Biophysical Properties in Glaucoma: Diagnostic Technologies" wrote himself). If you haven't found the necessary information about the book — write in the comments, we will try to find it.

This book provides an overview on new insights in glaucoma, the latest technological developments, scientific achievements, and novel research leading to new paradigms in glaucoma diagnosis. Readers will discover a broad picture starting from theoretical perspectives in diagnostic criteria followed by practical examination and clinical interpretations while highlighting potential pitfalls and limitations in analysis. Non-invasive, modern technologies allowing visualization and quantification of various parts of the human eye are fast evolving and improving interpretation of modern diagnostic possibilities are essential to fill the gap between sophisticated equipment, complex clinical data, and the need for precision-medicine based interpretation. Issues such as the importance of intraocular, intracranial, and ocular perfusion pressures (IOP, ICP, OPP) in the pathogenesis of glaucoma; and imaging modalities for examination of the optic nerve head, retinal fiber layer, and visual field assessment in glaucoma are explored in these chapters. The problem-based learning approach presented herein offers a succinct go-to-guide to read and discover answers.

Intraocular pressure Open-angle glaucoma

Intraocular pressure (IOP) is considered the main risk factor for the prevalence, incidence and progression of glaucoma [].

Large population-based studies showed that the level of IOP is a risk factor for glaucoma progression. (Table ].

Table 1.1

Studies investigating relationship between intraocular pressure and glaucoma progression

	Study	Results
Treatment vs. no treatment	CNTGS []	A 30% reduction in IOP reduces the risk of visual field progression from 80 to 40% in NTG subjects
EMGT []	A 25% reduction in baseline IOP reduces the risk of progression by 50% in OAG 1 mmHg reduction in IOP reduces risk of progression by 10%
OHTS []	>90% of untreated OHT patients had not converted to glaucoma after 5 years IOP lowering drops decrease OHT conversion to glaucoma rate from 10 to 5%
EGPS []	With IOP lowering drops OHT conversion to glaucoma rate is 7% In OHT placebo group the conversion rate is 15%
Different treatments	CIGTS []	Reducing IOP to 14 mmHg instead of 18 mmHg decreases by a third the proportion with >3 dB loss of visual field mean deviation
AGIS []	No progression only in eyes with IOP <18 mmHg

In ocular hypertension (OHT) conversions to glaucoma occurs in only a small number of patients despite elevated IOP. The Ocular Hypertension Treatment Study (OHTS) compared treatment versus no treatment in OHT [].

IOP fluctuations also play an important role in glaucoma progression. The diurnal IOP fluctuation is defined as difference between the highest and lowest IOP in a single day. Short-term fluctuations are defined as periods of days to weeks, while long-term IOP fluctuationsperiods of months to years. Diurnal IOP fluctuations up to 5 mmHg can occur in healthy subjects, while fluctuations 1030 mmHg have been detected in untreated glaucoma patients [].
