Foreword

When the authors proposed the realization of this book thought it might be useful for both ophthalmologists, and radiologists, and while ophthalmologists hubs tend to perform their scans, mostly other practices of ultrasound an performed only by radiologists. We intend, therefore, that this work will be useful for clinical practice and understanding of the images obtained by ultrasound, being directed to these various health professionals and to all those to whom it may concern the interpretation of ocular ultrasound. The introduction of the application of ultrasound in ocular exploration started in 1956 with the first publication of Mundt and Hughues on the usefulness of echography in the diagnosis of intraocular tumors from that time, till now, there have been several improvements, especially, since the introduction of ultrasound contact type B introduced by Bronson in 1972 then, the need to calculate the power of intraocular lenses in cataract surgery, added a new impetus with the emergence of biometrics. The latest changes in the ultrasound scan of the eye with ultrasound techniques including use of different frequencies, can sometimes confuse and complicate their proper use, we will guide the reader and provide as much information as possible. It is the intent of the authors to make an extensive review of ultrasound applied to the eye examination, and making the reader to understand that ultrasound, is helpful, especially to compare the images obtained with those achieved with other diagnostic eye as computed tomography, magnetic resonance, 18FDG-PET/CT scans, and other ophthalmic techniques as retinography or the optical coherence tomography.
