PURPOSE To report the sensitivity and specificity of B-scan ultrasonography to detect macular thickening. DESIGN Observational case series. METHODS Seventy-seven eyes of 40 consecutive patients (age range, 7-80 years) in a retinal specialty practice were examined. A single masked ultrasound operator performed B-scan ultrasonography on all eyes and graded macular thickening. The final assess...

Ultrasound imaging utilizes the interaction of sound waves with living tissue to produce an image of the tissue or, in Doppler-based modes, determine the velocity of a moving tissue, primarily blood. These dynamic, real time images can be analyzed to obtain quantitative structural and functional information from the target organ. This versatile, noninvasive diagnostic tool is widely used and ac...

PURPOSE To compare the precision of anterior chamber angle (ACA) and anterior chamber depth (ACD) measurements taken with ultrasound biomicroscopy (UBM) and the Artemis-2 Very High Frequency Ultrasound Scanner (VHFUS) in normal subjects. DESIGN Prospective study. METHODS We randomly selected one eye from each of 59 normal subjects in this study. Two subjects dropped out of the study; the as...
