Visual field defects in children with brain tumors

BMC Ophthalmology
Introduction Visual field defects (VFDs) are detected in up to 25% of children with brain tumors and early identification of VFDs is crucial for timely treatment and vision preservation.

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

Advanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

Visual Field Defects in Chiasmal Lesions

, 2021
Classic teaching states that compression of the optic chiasm impacts decussating nasal retinal axons producing a bitemporal hemianopia (BTH). In fact, visual field defects resulting from chiasmal lesions are quite variable1.

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

Advanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Comparison of the 24-2 and 10-2 SITA standard visual field strategies in patients with early-stage primary open-angle glaucoma and glaucoma suspects

The Pan-American Journal of Ophthalmology
Purpose: To compare the effectiveness of the 24-2 and 10-2 SITA Standard (SS) visual field strategies in detecting central defects in patients with early-stage primary open-angle glaucoma (POAG) and glaucoma suspects.

Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

Advanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Prognosis of Visual Field Defects in Stroke

, 2013
Stroke is the leading neurologic cause of visual impairment. Literature dealing with visual field recovery in cerebral strokes is surprisingly small. The aim of this study was to determine the prognosis of visual field defects due to strokes involving ...
