Written by well-known leaders in ophthalmic ultrasonography, this volume is a complete guide to the use of ultrasound as a primary diagnostic tool in ophthalmology. This thoroughly revised Second Edition reflects the latest developments in three-dimensional ultrasound and other advanced technologies and the expanding clinical role of ultrasound, including its use in refractive surgery, post-LASIK evaluation, and neuro-ophthalmology. Coverage includes detailed chapters on ocular diagnosis, orbital diagnosis, and very high-frequency digital ultrasound scanning in LASIK and phakic intraocular len |
