Echography (also ultrasound) is a clinical, non-invasive imaging module that is used for the measurement of the axial length of the eye and for the investigation of pathologic entities of the chamber angle, the iris and the ciliary body. Furthermore, its role in the management of vitreoretinal pathologies and the differentiation of intraocular tumors is indisputable. Echography remains the first-choice imaging tool in case of insufficient visualization of the posterior segment due to opacity or obstruction of the optical media of the eye. In addition, it can contribute to a more precise diagnostic characterization of lesions in all eye segments. Patients with corneal opacities, abnormalities of the iris, the chamber angle and the ciliary body, as well as patients with dense cataract, vitreous hemorrhage or inflammatory opacities can be properly diagnosed via ultrasound and be treated accordingly.

Differences in Ocular Biometry Between Short-Axial and Normal-Axial Eyes in the Elderly Japanese.
Clin Ophthalmol
January 2025
Department of Ophthalmology, Saitama Medical Center, Saitama Medical University, Kawagoe-shi, Saitama, Japan.
Purpose: Among patients with angle-closure glaucoma, it is common to have a short-axial eye, which also makes it difficult to select an appropriate intraocular lens. Previous studies have focused on the ocular biometry of the long-axial eye, whereas only a few reports have focused on the short-axial eye. This study aimed to clarify the characteristics of the short-axial eye on ocular biometry among the elderly Japanese.

Ophthalmic Physiol Opt
January 2025
Robert O Curle Ophthalmology Suite, Institute for Regeneration and Repair, The University of Edinburgh, Edinburgh, UK.
Purpose: To determine whether imaging features derived from fundus photographs contain 3D eye shape information beyond that available from spherical equivalent refraction (SER).
Methods: We analysed 99 eyes of 68 normal adults in the UK Biobank. An ellipsoid was fitted to the entire volume of each posterior eye (vitreous chamber without the lens)-segmented from magnetic resonance imaging of the brain.
A characterization study of the anterior segment morphology of patients with and without long-term silicone oil following vitrectomy.
Int Ophthalmol
January 2025
The University of Adelaide, North Terrace, Adelaide, SA, 5000, Australia.
Purpose: To characterize the anterior segment (AS) morphology of patients with long-term silicone oil (SiO) in situ (> 12 months) following pars plana vitrectomy (PPV).
Methods: This prospective, comparative characterization study was conducted between January 2022 and July 2023. Patients were included and sorted based on if they had undergone PPV without long-term SiO or had SiO in situ for at least 12 months at the time of review and image collection.
Lattice Boltzmann Modeling of Additive Manufacturing of Functionally Graded Materials.
Entropy (Basel)
December 2024
AGH University of Krakow, Faculty of Metals Engineering and Industrial Computer Science, al. Mickiewicza 30, 30-059 Kraków, Poland.
Functionally graded materials (FGMs) show continuous variations in properties and offer unique multifunctional capabilities. This study presents a simulation of the powder bed fusion (PBF) process for FGM fabrication using a combination of Unity-based deposition and lattice Boltzmann method (LBM)-based process models. The study introduces a diffusion model that allows for the simulation of material mixtures, in particular AISI 316L austenitic steel and 18Ni maraging 300 martensitic steel.

Eur J Ophthalmol
January 2025
Ophthalmology Department, ULS São José, Lisboa, Portugal.
Purpose: To compare changes in angle morphology, anterior chamber depth (ACD) and refractive prediction error (PE) after phacoemulsification between pseudoexfoliative (PEX) and non-PEX eyes.
Methods: Prospective case-control study of eyes submitted to cataract surgery. Biometric data and angle parameters - Anterior Chamber Angle (ACA), Angle Opening Distance (AOD), Scleral Spur Angles (SSA) and Trabecular Iris Space Area (TISA) - were measured preoperatively and 1-month postoperatively through swept-source anterior segment optical coherence tomography.
