Global metrics on ocular biometry: representative averages and standard deviations across ten countries from four continents

open access: yesEye, 2022
Background/Objectives We provide global averages and standard deviations for ocular biometry—axial length (AL), corneal radius of curvature (CR), anterior chamber depth (ACD), lens thickness (LT), white to white (WTW), and central corneal thickness (CT).

No sonographer, no radiologist: New system for automatic prenatal detection of fetal biometry, fetal presentation, and placental location

open access: yesPLoS ONE, 2022
Ultrasound imaging is a vital component of high-quality Obstetric care. In rural and under-resourced communities, the scarcity of ultrasound imaging results in a considerable gap in the healthcare of pregnant mothers.

Similarity of eyes in a cataractous population—How reliable is the biometry of the fellow eye for lens power calculation?

open access: yesPLoS ONE, 2022
Background In some situations it is necessary to use biometry from the fellow eye for lens power calculation prior to cataract surgery. The purpose of this study was to analyse the lateral differences in biometric measurements and their impact on the ...

ISUOG Practice Guidelines: ultrasound assessment of fetal biometry and growth

open access: yesUltrasound in Obstetrics and Gynecology, 2019
These Guidelines aim to describe appropriate assessment of fetal biometry and diagnosis of fetal growth disorders. These disorders consist mainly of fetal growth restriction (FGR), also referred to as intrauterine growth restriction (IUGR) and often ...

Comparison of Intraocular Lens Power Estimation by Optical Biometry and Ultrasound Biometry in Cataract Surgery [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2022
Introduction: The evolution of modern technologies for cataract surgery has made it crucial for aiming emmetropia with highly defined vision. The key factor responsible for postoperative emmetropia is an accurate biometry, along with various other ...

Postoperative Refractive Prediction Error Measured by Optical and Acoustic Biometry after Phacovitrectomy for Rhegmatogenous Retinal Detachment without Macular Involvement

open access: yesJournal of Ophthalmology, 2019
Introduction. The aim of this study was to investigate the postoperative prediction error measured by optical biometry and acoustic biometry in eyes after phacovitrectomy for rhegmatogenous retinal detachment (RRD) with no macular involvement.

Comparison of ultrasonic pachymetry, with a new optical biometry and tono-pachymetry

open access: yesMedicine Science, 2017
The aim of this study was to compare the measurements of central corneal thickness (CCT) using the CT-1P tonopachymetry and AL-Scan optical biometry with those obtained with ultrasound (US) pachymetry. In this prospective study, CCTs were measured in 100

Using microelectrode models for real time cell-culture monitoring [PDF]

open access: yes, 2011
This paper proposes a cell-microelectrode model for cell biometry applications, based on the area overlap as main parameter. The model can be applied to cell size identification, cell count, and their extension to cell growth and dosimetry protocols ...
