Colloidal self-assembly of soft neural interfaces from injectable photovoltaic microdevices

Mahmut Selman Sakar, Zhangjun Huang, Murat Kaynak, Haiyan Jia

Biomimetic retinas with a wide field of view and high resolution are in demand for neuroprosthetics and robot vision. Conventional neural prostheses are manufactured outside the application area and implanted as a complete device using invasive surgery. He ...

Photovoltaic stimulation of retinal microcircuit for vision restoration

Naïg Aurelia Ludmilla Chenais

Sight restoration through retinal prostheses was still a mere dream a century ago. Current challenges are even greater: providing a quantitatively and qualitatively useful artificial vision to late blind patients. Existing approaches all face engineering a ...

En face retinal imaging

Dino Carpentras

Retinal imaging is routinely used to provide information about vision health. Recent studies showed that retinal images can also provide information on general health (e.g. stress level), brain pathologies and attention. Depending on the target information ...

Enhanced Compressed Look-up-Table Based Real-Time Rectification Hardware

Alexandre Schmid, Yusuf Leblebici, Abdulkadir Akin, Halima Najibi, Luis Manuel Gaemperle

Real-time disparity estimation requires real-time rectification which involves solving the models of lens distortions, image translations and rotations. Low complexity look-up-table based rectification algorithms usually require an external memory to store ...

Enrichment of pathogenic alleles in the brittle cornea gene, ZNF469, in keratoconus

Keratoconus, a common inherited ocular disorder resulting in progressive corneal thinning, is the leading indication for corneal transplantation in the developed world. Genome-wide association studies have identified common SNPs 100 kb upstream of ZNF469 s ...

Innovative strategy of corneal epithelium regeneration using fabricated soft contact lens containing cavities for stem cells transplantation

Julien Graber

Transplantation of donor cornea is widely performed with a high success rate to treat patients with impaired corneal transparency. However the limited number of donors has led scientists to search for new technologies and treatments, including stem cell th ...

Wireless contact lens sensor for intra ocular pressure monitoring: assessment on enucleated pig eyes

Philippe Renaud, Arnaud Bertsch, Matteo Leonardi, André Mermoud

Purpose: Assessment on enucleated pig eyes of a novel and minimally invasive method for the continuous monitoring of intraocular pressure (IOP), based on a novel wireless contact lens sensor (CLS). Methods: The wireless CLS is a disposable silicone soft co ...

Second harmonic generating (SHG) Nanoprobes: A new tool for biomedical imaging

Demetri Psaltis, Ye Pu, Ye Pu

Cornea functions as an outermost lens and plays an important role in vision. For cornea diagnosis and treatment, a microscopic imaging system with cellular resolution and high eye safety is strongly desired. Recently, the cell morphology of corneal epithel ...

NR2E3 Mutations in Enhanced S-Cone Sensitivity Syndrome (ESCS), Goldmann-Favre Syndrome (GFS), Clumped Pigmentary Retinal Degeneration (CPRD), and Retinitis Pigmentosa (RP)

Pascal Escher

NR2E3, also called photoreceptor-specific nuclear receptor (PNR), is a transcription factor of the nuclear hormone receptor superfamily whose expression is uniquely restricted to photoreceptors. There, its physiological activity is essential for proper rod ...

A colloidal approach to eye lens protein mixtures : relevance for cataract formation

Nicolas Dorsaz

A broad and constantly growing class of diseases, such as Alzheimer's disease, sickle-cell or cataract, involves protein association phenomena as an essential aspect. The common denominator of all the members of this class of molecular condensation disease ...
