The vitreous humour is a clear gel positioned behind the iris (coloured part) and the lens, and in front of the retina (back of the eye). Vitrectomy is the surgical removal of the vitreous humour, a procedure needed to allow ophthalmic surgeons to diagnose and treat underlying disease in the eye. This new edition provides a step by step guide to vitrectomy surgeries. Beginning with a description of the anatomy and physiology, the role of optical coherence tomography and anaesthesia, the following chapters discuss vitrectomy procedures for different ocular diseases and disorders. Written by a recognised Spanish author and editor team, the second edition includes new chapters, more than 350 full colour images and illustrations, and a DVD demonstrating vitrectomy surgery.   Key points Step by step guide to vitrectomy surgery Includes new chapters Features more than 350 colour images and illustrations Includes DVD Spanish author and editor team Previous edition published in 2006
