Abstract : The effects of ultrasonic transducer manipulations on optical component depth and component interface amplitudes in the live primate eye were investigated. Statistical evidence is presented which suggests that as the ultrasound beam traverses the optical components of refraction, increased variability in depth and amplitude measures occur. Angular transducer displacement from the criterion 'standard trace' has a greater effect on depth and amplitude measures than did linear displacement from the 'standard trace.' The most sensitive amplitude measure was that of the front lens. Optical component depth meaures were much less sensitive to transducer movement than were component amplitude measures. (Author)
