This third Glaucoma volume of the Essentials in Ophthalmology series, as in the first and the second, provides a picture of recent progress in the field of glaucoma, in both basic clinical research and applied clinical science. Its intention is not to replace textbooks on glaucoma, but to serve as a conceptual bridge between original research and textbook presentation. The editors have set out to provide the reader with diverse and interesting topics reflective of the evidence-based, modern approach to the field of glaucoma. The book’s well-structured text and new design is quick and easy to read.
