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 ...

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.

Ultrasound biometry and fetal growth restriction
Fetal and Maternal Medicine Review, 2002With the ascendancy of biophysical assessment with Doppler velocimetry, and the establishment of routine scan dating in early pregnancy, there needs to be a radical re-think of the role of ultrasound biometry in the definition and assessment of fetal growth restriction (FGR).Doppler flow velocimetry of the umbilical artery has proven its value in ...

Ultrasound biometry in the diagnosis of amblyopia in keratoconus
Contact Lens and Anterior Eye, 2006Here, we describe a case in which A-scan ultrasound biometry was used to differentially diagnose the cause of reduced vision in a patient with keratoconus. A patient with keratoconus presented with reduced visual acuity in one eye, not improvable above 6/18 with specialist keratoconus contact lens fitting.

Biometry/Axial Length in Ophthalmic Ultrasound
Journal of Diagnostic Medical Sonography, 1999Biometry/axial length is an A-scan measurement from theeleading edge of cornea to the leading edge of the retina. This measurement is used to calculate the implant power of the intraocular lens (IOL). The biometry examination is a primary Wand essential part of cataract extraction and IOL surgery.

[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.

Submandibular gland biometry by high frequency ultrasound
Journal of the Anatomical Society of India, 2016Abstract Introduction Submandibular glands are involved in many disease processes. Acute viral and bacterial inflammatory diseases are the most common causes of submandibular gland enlargement. Reduction in their size is observed in chronic inflammation and after radiation therapy. Various benign and malignant neoplasms also affect them.

Axial Length Scanning: Laser Interferometry Versus Ultrasound Biometry
Annals Of Ophthalmology, 2004In cataractous patients, the authors measured the axial length (AL) using both partial coherence laser interferometry (PCLI) and ultrasound biometry (UB), the latter performed by both an experienced and inexperienced operator. Both sets of AL measurements were compared to theoretical (calculated) AL values.
