Advances in myopia research anatomical findings in highly myopic eyes

Eye and Vision, 2020
Background The goal of this review is to summarize structural and anatomical changes associated with high myopia. Main text Axial elongation in myopic eyes is associated with retinal thinning and a reduced density of retinal pigment epithelium (RPE ...

IN4MER Biomaterial Ink: A Phosphorescent Biosensing Biomaterial Ink for Multiple Analytes (Glucose, Lactate, Oxygen) Measurements and Temperature Sensing Applications

Advanced Functional Materials, EarlyView.
Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

Advanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

Measurements of axial length and radius of corneal curvature in the rabbit eye.

Acta medica Okayama, 1997
The axial length of the eye, the radius of the anterior corneal surface, and the diameter of the cornea were measured on 40 eyes of 20 New Zealand White rabbits. The ultrasonographic measurements of the axial length of the eye showed a mean value of 15.12 ± 0.51mm (15.33 ± 0.50mm in males, 14.96 ± 0.46mm in females).

Gene Therapy Restores Mfrp and Corrects Axial Eye Length [PDF]

Scientific Reports, 2017
AbstractHyperopia (farsightedness) is a common and significant cause of visual impairment, and extreme hyperopia (nanophthalmos) is a consequence of loss-of-function MFRP mutations. MFRP deficiency causes abnormal eye growth along the visual axis and significant visual comorbidities, such as angle closure glaucoma, cystic macular edema, and exudative ...

How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

Advanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Changes in optical axial length of the eye with accommodation

JAPANESE ORTHOPTIC JOURNAL, 2003
今回、我々は非接触型光学式眼軸長測定装置(IOLマスター)を用いて、調節時及び非調節時の眼軸長、瞳孔径、前房深度を測定し、それぞれ比較検討した。対象は眼疾患の無い正常者5名10眼、平均年齢23.5±1.5歳である。調節時及び非調節時の眼軸長を測定した結果、調節時眼軸長が長く測定された ...

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...
