Finite Element Analysis of Ocular Impact Forces and Potential Complications in Pickleball-Related Eye Injuries.

Pickleball, the fastest-growing sport in the United States, has seen a rapid increase in participation across all age groups, particularly among older adults. However, the sport introduces specific risks for ocular injuries due to the unique dynamics of gameplay and the physical properties of the pickleball. This study aims to explore the mechanisms of pickleball-related eye injuries, utilizing finite element modeling (FEM) to simulate ocular trauma and better understand injury mechanisms.

Finite element analysis of asymmetrical retinal hemorrhages in shaken baby syndrome.

Background: Despite the common association between bilateral retinal hemorrhage and shaken baby syndrome (SBS), unilateral retinal hemorrhage does not necessarily exclude this diagnosis. This study used computational simulations to elucidate the biomechanical phenomena within the eye under asymmetrical shaking forces.

Methods: Finite element analysis (FEA) incorporating the vitreous, vitreoretinal interface, retinal layers, and retinal vessels was performed under asymmetrical shaking conditions.

Evaluating the Influence of Morphological Features on the Vulnerability of Lipid-Rich Plaques During Stenting.

Lipid-rich atheromas are linked to plaque rupture in stented atherosclerotic arteries. While fibrous cap thickness is acknowledged as a critical indicator of vulnerability, it is likely that other morphological features also exert influence. However, detailed quantifications of their contributions and intertwined effects in stenting are lacking.

Finite Element Analysis of Mechanical Ocular Sequelae from Badminton Shuttlecock Projectile Impact.

Purpose: With the growing popularity of badminton worldwide, the incidence of badminton-related ocular injuries is expected to rise. The high velocity of shuttlecocks renders ocular traumas particularly devastating, especially with the possibility of permanent vision loss. This study investigated the mechanism behind ocular complications through simulation analyses of mechanical stresses and pressures upon shuttlecock impact.

The role of intrapartum fetal head compression in neonatal retinal hemorrhage.

Purpose: Neonatal retinal hemorrhage is a common finding in newborns, but the underlying mechanisms are not fully understood. A computational simulation was designed to study the events taking place in the eye and orbit when the head is compressed as the neonate passes through the birth canal.

Methods: A finite element model of the eye, optic nerve sheath, and orbit was simulated and subjected to forces mimicking rises in intracranial pressure (ICP) associated with maternal contractions during normal vaginal delivery.
