L’ophtalmologie est une spécialité assez technique, complexe, et pour laquelle les patients viennent souvent nous consulter. Ce travail de fin d’études aborde les problèmes ophtalmologiques rencontrés dans le quotidien du généraliste. Quel matériel de base se révèle utile dans notre pratique ? Que devons-nous savoir faire ? Quels diagnostics ne pouvons-nous pas rater ?

Fluorescein angiography is an indispensable tool in modern ophthalmology. It is founded on the evaluation of phenomena related to the behavior intravenously administered sodium fluorescein in the tissues of the ocular fundus. Commonly, texts on fluorescein angiography merely describe the typical pattern, quality, and quantity of the phenomena specific to a variety of vascular and other diseases of the retina and choroid. In contrast, the present book deals with the morphological prerequisites and structural changes on which the individual phenomena are based. This knowledge provides the retina specialist, the general ophthalmologist, and the basic scientist alike with valuable information toward understanding the nature and mechanism of the underlying disorders. The book represents a unique mixture of textbook and atlas, always combining concise statements in English, German, and Spanish on one page with didactically conceived explanatory illustrations on the facing page.

The technology of angiographic systems has been improved tremendously just within the past few years. This has allowed greatly increased levels of image resolution for both fluorescein and indocyanine green angiography. This new atlas by Dithmar and Holz covers the basic principles of the new methods for fluorescein- and indocyanine green-angiography, as well as the high resolution imaging of fundus autofluorescence. The angiographic signs of retinal and choroidal diseases are illustrated with images taken from a series of clinically relevant case examples that specifically illustrate the advantages of higher image resolution for the study of common retinochoroidal disorders. In so doing, this atlas offers an all-encompassing survey of the many angiographic signs in these disorders and their differential diagnoses. Clinicians in all subspecialties of ophthalmology can profit from a better understanding of these pathophysiological phenomena.

Bacterial nanocellulose (BNC), cellulose nanocrystals (CNCs), and cellulose nanofibers (CNFs) are three nanometric forms of the most abundant natural polymer (viz. cellulose), and are currently under the spotlight in numerous fields of modern science and technology. The eco-friendly connotations, peculiar features, and multiple functionalities of these nanoscale cellulosic substrates are being explored to engineer advanced nanocomposites and nanohybrid materials for application in manifold domains, such as mechanics, optics, electronics, energy, environment, biology, and medicine.The aim of this Special Issue titled “Advanced Nanocellulose-Based Materials: Production, Properties, and Applications” is to gather original research and review contributions from the world-leading scientists working with nanocellulose. Thus, research that is representative of the current developments dealing with the production methodologies, properties, and applications of nanocellulose-based materials (e.g., nanocomposites, hybrids, aerogels, hydrogels, films, and fibers) are presented in the Special Issue.
