Clinical Evaluation of An Inexpensive Ultrasound Oculometer for Ocular Biometry

American Journal of Ophthalmology, 1979
We measured anterior chamber depth and axial length in 200 human eyes with the Echo-Oculometer and the Digital Biometric Ruler. There was good agreement between measurements with the two instruments. The echo-Oculometer is much less expensive than any other instrument available for measuring ocular axial length and satisfactorily provides information ...

Ultrasound fetal biometry charts for a North American caucasian population

Journal of Clinical Ultrasound, 1998
This study was done to produce enhanced fetal biometry charts and graphs presenting percentile values as a function of fetal age.The relationships between the ultrasound measurements of 10 fetal parameters and menstrual age were determined by a cross-sectional study. Data were obtained from 508 to 790 fetuses.

[Ultrasound biometry of the fetal heart].

Zentralblatt fur Gynakologie, 1992
We report on biometric measurements of the fetal heart with the TM-technique; these measurements were carried out between the 20th and 40th gestational week. The right and left endsystolic atrial and ventricular diameters were, measured, as well as the diameters of the large vessels, i.e.

Optical Biometry versus Applanation Ultrasound Biometry in Axial Eye Length Measurement in Pseudophakia

The Egyptian Journal of Hospital Medicine, 2017
Purpose: to compare axial eye length (AEL) measurement in pseudophakic eyes by optical biometry and applanation ultrasound (u/s) biometry. Methods: a prospective, case controlled and comparative study was performed at Al-Zahraa University Hospital clinic from (January 2016 – December 2016).
