GLIOMA OF THE RETINA. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1898
In the eye section of the Ninth International Medical Congress, an eminent specialist of Paris said: "I have seen but four cases of glioma of the retina." This struck me as being a very small number, and led me to look over my records of the years 1871 to 1898, inclusive. I shall, therefore, briefly report them as follows: Case 1. —Girl, aged 1 year,

Implantable Light‐Powered Human Designer Cells for Electrical Energy Generation

open access: yesAdvanced Materials, EarlyView.
Inspired by the eel's electric organ, a miniature implantable biohybrid device is developed to generate electricity under light activation. The device utilizes a light‐dependent ion gradient formation that induced by genetically engineered human designer cells that express light‐sensitive membrane ion channels and proton pumps, working in synergy with ...

Serous Macular Detachments

open access: yesTürk Oftalmoloji Dergisi, 2012
Serous macular detachment has only recently been recognized to occur in a significant number of eyes with macular pathology including diabetic retinopathy, retinal vein occlusion, Behçet disease, Irvine-Gass syndrome and pars planitis.

Reconstructing the retina [PDF]

open access: yesNature, 2018
The ways in which lost vision might be restored are coming into focus as researchers move closer to recreating the eye’s most complex structure — the retina — in the laboratory.

Interactions Between Active Matters and Endogenous Fields

open access: yesAdvanced Materials, EarlyView.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Microperimetry

open access: yesTürk Oftalmoloji Dergisi, 2011
Visual acuity is still considered the gold standard in clinical practice of vision testing, but it does not entirely reflect functional vision. Therefore, we need other functional tests to perform more detailed assessment of macular function in retinal ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...
