A review of non-strabismic accommodative-vergence anomalies in school-age children. Part 1: Vergence anomalies

African Vision and Eye Health, 2015
Comfortable reading and the performance of near point activities involve efficient accommodative and vergence systems. However, accommodative and vergence anomalies are associated with various symptoms that impair efficient near point tasks.

The Cuttlebone Blueprint for Multifunctional Metamaterials: Design Taxonomy, Functional Decoupling, and Future Horizons

Advanced Functional Materials, EarlyView.
Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

Post-traumatic Convergence Insufficiency with Associated Accommodative Disorders in a Patient after Blunt Head Trauma

Okulistyka
Blunt head trauma is often accompanied by visual disturbances that require comprehensive ophthalmological evaluation. These symptoms may be transient and sometimes resolve spontaneously, but they should not be ignored, as they may indicate significant ...

Complexation‐Mediated Diffusion‐Limited Crystal Growth: A General Framework for Anisotropic Crystal Growth in Cu‐Based Perovskites

Advanced Functional Materials, EarlyView.
A Complexation‐Mediated Diffusion‐Limited Growth (CMDLG) framework is established to rationalize the anisotropic growth of lead‐free perovskites. Integrating coordination chemistry with mass transport kinetics, this study theoretically derives and experimentally validates that stable iodocuprate complexes induce a diffusion‐limited regime.

The Correlation Between Eye Strain on Visual Acuity with Refractive Error Among Children

Journal of Pharmacy and Bioallied Sciences
Background: Visual impairment is a significant public health problem. Computer use by children especially school-aged children is growing rapidly. In these decades, therefore, extensive viewing of the computer screen can lead to eye discomfort, fatigue ...

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

Advanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

Dispensing Volumetric Additive Manufacturing

Advanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Algorithmic Design of Disordered Networks With Arbitrary Coordination: Application to Biophotonics

Advanced Functional Materials, EarlyView.
Predictive Design of Disordered Networks: Disordered network‐like morphologies are abundant in nature, from cytoskeletal networks to bone structures and chalcogenide glasses. These structures are naturally hard to characterize. A new algorithmic tool extends the established Wooten–Weaire–Winer (WWW) algorithm to valencies above 4.

The Near Point of Convergence in Patients with Vestibular Migraine

International Archives of Otorhinolaryngology
Introduction Vestibular migraine (VM) is one of the most common vestibular disorders and its diagnosis is based entirely on clinical features. A recent case series suggested a possible link between migraines and convergence insufficiency.
