Automatic biometry of fetal brain MRIs using deep and machine learning techniques

Scientific Reports, 2023
Linear biometric measurements on magnetic resonance images are important for the assessment of fetal brain development, which is expert knowledge dependent and laborious.

Accuracy of newer intraocular lens power formulas in short and long eyes using sum-of-segments biometry

Journal of cataract and refractive surgery, 2022
The best overall results with the sum-of-segments biometry were noted with the B II, BTAL, EVO, Hoffer QST, K6, Kane, Olsen, and PEARL-DGS formulas. Purpose: To analyze the accuracy of newer intraocular lens power formulas in long and short eyes measured

Comparison of computed tomographic ocular biometry in brachycephalic and non-brachycephalic cats [PDF]

Veterinary World, 2021
Background and Aim: Ocular biometry has been used to evaluate ocular parameters; however, several factors need to be considered. In humans, age and sex have been shown to affect ocular biometry.

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

Eye, 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).

Refractive surprise after cataract surgery secondary to smeared optics of swept-source optical coherence tomography biometer: a case report

BMC Ophthalmology, 2020
Background Inaccurate biometry can lead to the wrong intraocular lens implantation and result in refractive surprise following cataract surgery. It is important to be sceptical of biometry results that do not match the refractive or clinical picture and ...

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

PLoS 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.

International standards for fetal brain structures based on serial ultrasound measurements from the Fetal Growth Longitudinal Study of the INTERGROWTH-21st Project. [PDF]

, 2020
OBJECTIVE: To create prescriptive growth standards for five fetal brain structures, measured by ultrasound, from healthy, well-nourished women, at low risk of impaired fetal growth and poor perinatal outcomes, taking part in the Fetal Growth Longitudinal

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

PLoS 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 ...
