Normal Ultrasound

Living reference work entry


Ultrasound has become a standard diagnostic modality in almost all medical specialties. The 10 Mhz probe provides an excellent resolution of 940 microns with a restricted depth of 4 cm imaging the posterior segment of the eye quiet well. A thorough understanding of the ultrasound principles makes the diagnosis of a variety of intraocular pathologies easy and quick. It is a non-invasive imaging technique that can help a uveitis specialist in the diagnoses of intra as well as extra ocular diseases. The chapter describes normal appearance of structures on USG, relevant to uveitic pathology.
