Diagnostic Ultrasonography of the Eye

Abstract

This book describe about A-scan & B-scan ultrasonography of Eye. A-scan is an amplitude modulation scan. It gives the information in the form of one dimensional. This book tells about ultrasound biometry, commonly referred to as A-scan, which is routine type of diagnostic test used in ophthalmology. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. There are several different formulas are given in this book that can be used depending on the actual characteristics of the eye. The other major use of the A-scan is to determine the size and ultrasound characteristics of masses in the eye, in order to determine the type of mass. This is often termed quantitative A-scan.
