In this book Krause summarizes, correlates and critically discusses the results of biochemical research on the eye. The material covers nearly one thousand references scattered over a period of more than one hundred years. The data have been selected from works on physiology, anatomy, pathology, immunology, chemistry and ophthalmology. The material is arranged in eight chapters: "External Secretions and Conjunctiva" ; "The Sclera"; "The Cornea" ; "The Uveal Tract" ; "The Retina"; "The Aqueous Humor"; "The Vitreous Humor," and "The Lens."
