A numerical model of the human cornea accounting for the fiber-distributed collagen microstructure [PDF]

arXiv, 2023
We present a fiber-distributed model of the reinforcing collagen of the human cornea. The model describes the basic connections between the components of the tissue by defining an elementary block (cell) and upscaling it to the physical size of the cornea.

Changes in Intraocular Pressure After Exercise in Newly Diagnosed Glaucoma Patients and Normal Subjects – A Pilot Study [PDF]

, 2020
Glaucoma is a growing public health challenge and raised intraocular has been found to be the only modifiable risk factor. The aim of this study was to assess the effect of exercise on intraocular pressure.

Multifunctional Biomimetic Nanotherapeutics for Anti‐Oxidative and Anti‐Inflammatory Synergistic Therapy of Corneal Neovascularization

Aggregate, EarlyView.
An anti‐inflammatory and antioxidant metal‐organic framework (MOF) nanoplatform was prepared via one‐pot self‐assembly. In vitro and in vivo studies demonstrated that the prepared MVPC nanoparticles can effectively scavenge overproduced reactive oxygen species at diseased sites, enhance IL‐10 secretion, and suppress VEGFA expression, offering a novel ...

Needle detection and localisation for robot‐assisted subretinal injection using deep learning

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Subretinal injection is a complicated task for retinal surgeons to operate manually. In this paper we demonstrate a robust framework for needle detection and localisation in robot‐assisted subretinal injection using microscope‐integrated Optical Coherence Tomography with deep learning.

Modeling and FEM-based Simulations of Composite Membrane based Circular Capacitive Pressure Sensor [PDF]

arXiv, 2019
In Micro-electro-mechanical Systems (MEMS) based pressure sensors and acoustic devices, deflection of a membrane is utilized for pressure or sound measurements. Due to advantages of capacitive pressure sensor over piezoresistive pressure sensors (low power consumption, less sensitive to temperature drift, higher dynamic range, high sensitivity ...

Costello Syndrome and Ophthalmologic Issues: Unveiling the Unseen

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Costello syndrome (CS) is an ultra‐rare condition belonging to the RASopathies, a group of disorders characterized by aberrant RAS/MAPK pathway signaling, which is involved in ocular development and in some eye pathologies. However, only a few studies assessing the ophthalmic features of individuals with CS are available.
