Glaucoma remains one of the leading causes of blindness. Laser scanning tomography has gained an indispensable role in the ophthalmologic diagnosis, especially in the long-term follow-up of glaucoma. Confocal laser scanning ophthalmoscopy provides key insights into the three-dimensional anatomy of the optic disc in vivo. This unique atlas contains superb images of all clinically relevant diseases diagnosed by current models of the Heidelberg Retina Tomograph. It correlates classical diagnostic tools like perimetry and fundus photography with state-of-the-art studies including digital retinal angiography, optical coherence tomography and laser scanning tomography. Special features include the illustrated coverage of:

Diseases of the optic nerve head; different types and stages of glaucoma, non-glaucomatous neuropathy and papilledema; automated classification procedures for the detection of glaucoma; strategies for the interpretation of follow-up results in optic disc monitoring.

Macular diseases: the shortly released Retina Module expands the diagnostic spectrum of laser scanning ophthalmoscopy significantly, adding measuring and monitoring of diabetic and cystoid macular edema.

This atlas is the most comprehensive up-to-date reference of laser scanning ophthalmoscopy available, ideal for residents and general ophthalmologists who want to enhance their diagnostic skills.

This book, a translation of the German volume n-Ecke, presents an elegant geometric theory which, starting from quite elementary geometrical observations, exhibits an interesting connection between geometry and fundamental ideas of modern algebra in a form that is easily accessible to the student who lacks a sophisticated background in mathematics. It stimulates geometrical thought by applying the tools of linear algebra and the algebra of polynomials to a concrete geometrical situation to reveal some rather surprising insights into the geometry of n-gons. The twelve chapters treat n-gons, classes of n-gons, and mapping of the set of n-gons into itself. Exercises are included throughout, and two appendixes, by Henner Kinder and Eckart Schmidt, provide background material on lattices and cyclotomic polynomials. (Mathematical Expositions No. 18)
