This book became possible after much encouragement from colleagues and friends. For a long time, I wanted to write something similar for the main reason that some colleagues had difficulty understanding the details of the field. Some of them even minimizing its value, considering its usefulness superficial.

There is nothing very complicated in campimetry. Fortunately, it is a very visual matter, as are lesions of the neural fibers of the retina and the optic nerve head. Something similar to disciplines such as Anatomy, Histology, and Histopathology, among others.

The main purpose of this book is to intend to make interest in campimetry possible, encouraging the recall of what has been learned and forgotten, or the learning to use an underutilized resource, which can facilitate not only the daily work of each one but also allows improve the vision of patients, carriers of pathologies that can be resolved or mitigated, adding, at least, hope.
