Ultrasound biometry and deprivation myopia
1993Lid-suture has been demonstrated as a myopia-inducing mechanism in young experimental animals, and deprivation myopia is now considered a keyword in myopia pathogenesis. As human counterparts we might expect the development of many cases of axial myopia in patients with obstacles to clear retinal image formation in early life, although there have been ...

[Ultrasound biometry in childhood].
Klinische Monatsblatter fur Augenheilkunde, 1988Within the last 18 months the authors have measured, in cases of juvenile cataract seen by them, the axial length of the eye and other parameters. As a control group, children from the authors' squint clinic, with various refractive errors, were examined.

[The reliability of ultrasound biometry].
Klinische Monatsblatter fur Augenheilkunde, 1990Preoperative ultrasonic biometry is indispensible in cataract surgery in order to calculate the power of the intraocular lens to be implanted. Various authors have suggested that the accuracy of the measurements could be improved by performing biometry several times and basing the calculation of the lens on the mean value.

Clinical Evaluation of An Inexpensive Ultrasound Oculometer for Ocular Biometry
American Journal of Ophthalmology, 1979We 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 biometry of the fetal heart].
Zentralblatt fur Gynakologie, 1992We 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.

Assessment of Fetal Biometry Using Ultrasound Images
2020 IEEE International Conference on Advances and Developments in Electrical and Electronics Engineering (ICADEE), 2020Assessment of the fetal biometry is one of the important tasks during every phase of pregnancy. The fetal biometry obtained from the fetal Ultrasound images demands well trained and skilled sonographers for the accurate measurements. The fetal biometry are obtained by drawing circles and lines using cursor on the images which may lead to inaccurate ...
