Physiology of the Eye: An Introduction to the Vegetative Functions, Second Edition discusses the fundamental concept of the operating process of the visual system. The book is comprised 10 chapters that cover the functions and properties of the parts of the ocular system. The text first provides a review of ocular anatomy, and then proceeds to covering parts, including aqueous humor, vitreous body, and lens. The next two chapters deal with various concerns in cornea, such as swelling pressure and metabolism. Chapter 8 discusses the sclera, while Chapter 9 tackles the retina. The last chapter talks about the tears and the lids. The book will be most useful to both optometrists and ophthalmologists. Readers who are curious about the operating process of the eye will find this text interesting.
