Successful gonioscopy is critical in the diagnosis of glaucoma and is an essential element of any thorough eye examination. It is also one of the most difficult ophthalmological techniques to learn and perform. The second edition is a comprehensive introduction to gonioscopic techniques and a vital manual for clinicians wishing to be proficient in examining the anterior segment of the eye. Highlights include new sections on selective laser trabeculoplasty, ultrasound biomicroscopy, and anterior segment ocular coherence tomography; updated text and references; and, nearly 400 drawings and photographs. To vividly illustrate key examination techniques, a supplemental DVD features video clips of 12 basic and advanced gonioscopic techniques.
