This book examines the fundamental physics of ultrasound, including the indications for and findings of the technique and how to accurately diagnose common and rare clinical entities of the eye and orbit. The chamber angle in the setting of narrow angle glaucoma, vitreo-retinal diseases and other posterior segment problems (choroid, sclera, posterior pole), trauma of the anterior and posterior segments intraocular tumors, orbital masses and lesions in both adults and children are discussed in detail throughout the book. This book is an essential resource for ophthalmologists, radiologists, sonographers, as well as for residents and fellows in ophthalmology seeking a comprehensive approach to ophthalmic echography.
