Electroretinography, the measurement of the potential change across the eye under the influence of a light stimulus, may be performed as a noninvasive procedure. For this reason, it has clinical utility and is highly important in the early diagnosis of retinal degenerative disease, particularly retinitis pigmentosa.
Dr Armington has brought the subject up to date in the tradition of the books of Granit (1947) and Brindley (1960). The book deals with both the theory and practice of electroretinography. Whereas one could not record an electroretinogram with the help of the book alone, the extensive bibliography and the book itself would point a newcomer in the right direction. Among physicians, only the ophthalmologist, and among ophthalmologists, chiefly those with retinal interests are the intended readership. Visual psychologists and visual physiologists will profit from having this book available.
