Simvastatin-Induced Ferroptosis in Orbital Fibroblasts in Graves' Ophthalmopathy.

Purpose: Graves' ophthalmopathy (GO), the most common extrathyroidal manifestation of Graves' disease, is disabling and disfiguring. Recent studies have shown that statins have a protective effect on individuals with GO. Statins were reported to trigger ferroptosis in some disorders, but little is known about whether statins protect against GO via ferroptosis.

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation.

Corneal substitutes with structural and compositional characteristics resembling those of natural corneas have attracted considerable attention. However, biomimicking the complex hierarchical organization of corneal stroma is challenging. In this study, humanized corneal stroma-like adhesive patches (HCSPs) are prepared through a multi-step process.

A randomized sequential cross-over trial evaluating five purportedly ICP-lowering drugs in idiopathic intracranial hypertension.

Objective: To gain initial insight into the efficacy to lower intracranial pressure (ICP), side effects, and effects on cognition of five drugs commonly used to treat idiopathic intracranial hypertension (IIH).

Background: Limited clinical data exist for the treatment for IIH. Impaired cognition is recognized in IIH and can be exacerbated by medications.

Methods: This study involved a single-center, non-randomized clinical prospective cohort research design including 39 patients with myopic CNV and a control group of 10 patients with cataract.

Laminated Layer Extract from Echinococcus Granulosus cyst Attenuates Ocular Damages and Inflammatory Responses in an Experimental Autoimmune Uveitis Model.

Purpose: Since extract of the laminated layer (LL) from E. granulosus showed immuno-modulatory effects in vitro and in vivo, we sought to determine its effect on the onset, development, and evolution of experimental auto-immune uveitis (EAU). The latter is a model of some human diseases with ocular inflammation that can cause blindness.

The three-phase approach included: (1) removal of the epikeratophakia lenticule, (2) cataract extraction with intraocular lens implantation, and (3) transepithelial topography-guided photorefractive keratectomy (trans-PRK).

Five years comparation of efficacy and safety after ICL-V4c implantation for high and super high myopia correction.

Objectives: The objective of the investigation is to examine the long term efficacy, safety, and predictability of ICL-V4c implantation for high and super-high myopic patients in order to provide reliable guidance for the selection of refractive surgical procedures.

Methods: We reviewed 125 eyes from 64 patients who implanted ICL-V4c at the Refractive Surgery Center of West China Hospital in Chengdu, China, between May 2015 and January 2017. These eyes were divided into two groups based on their preoperative spherical equivalent (SE) degree: high myopia (≥ -10D) and super-high myopia groups (< -10D).

Factors Associated with Adherence to Diabetic Retinopathy Screening Among Patients Attending a Nurse-Led Community Clinic in Australia: A Qualitative Study.

Despite the availability of screening services, the rate of diabetic retinopathy (DR) screening continues to be suboptimal in Australia, necessitating improvement. However, improving DR screening rates requires a more comprehensive understanding of the factors influencing adherence to the screening recommendations. This study aimed to explore the factors that influence adherence to DR screening among people with diabetes attending a community screening clinic in Australia.

Molecular Findings Before Vision Loss in the Streptozotocin-Induced Rat Model of Diabetic Retinopathy.

The streptozotocin-induced rat model of diabetic retinopathy presents similarities to the disease observed in humans. After four weeks following the induction of diabetes, the rats experience vision impairment. During this crucial four-week period, significant changes occur, with vascular damage standing out as a clinically significant factor, alongside neovascularization.

Derivation and Characterization of Isogenic Mutant and Control Human Pluripotent Stem Cell Lines.

Dominant optic atrophy (DOA) is the most commonly inherited optic neuropathy. The majority of DOA is caused by mutations in the gene, which encodes a dynamin-related GTPase located to the mitochondrion. OPA1 has been shown to regulate mitochondrial dynamics and promote fusion.

ADAMTS13 Improves Endothelial Function and Reduces Inflammation in Diabetic Retinopathy.

The protease, a disintegrin and metalloproteinase with thrombospondin type 1 motif member 13 (ADAMTS13), known to cleave only the von Willebrand factor (VWF), has powerful regulatory effects on microvascular platelet adhesion, thrombosis, inflammation, and endothelial dysfunction. We study the protection against diabetes-induced retinal injury in experimental rats by supplementation with recombinant ADAMTS13. We compare human epiretinal membranes and vitreous samples from nondiabetic subjects and patients with proliferative diabetic retinopathy (PDR) and extend in vitro analyses with the use of various immunodetection and spectrofluorimetric methods on rat retina and human retinal glial and endothelial cell cultures.

Diagnostic Errors in the Acutely Dizzy Patient-Lessons Learned.

Acute vertigo or dizziness is a frequent presentation to the emergency department (ED), making up between 2.1% and 4.4% of all consultations.

The Application of Terahertz Technology in Corneas and Corneal Diseases: A Systematic Review.

Terahertz (THz) waves reside in the electromagnetic spectrum between the microwave and infrared bands. In recent decades, THz technology has demonstrated its potential for biomedical applications. With the highly unique characteristics of THz waves, such as the high sensitivity to water and optimal spatial resolution coupled with the characteristics of the human cornea, such as its high water content, THz technology has been explored as a potential modality to assess corneas and corneal diseases.

Spectral Analysis of Light-Adapted Electroretinograms in Neurodevelopmental Disorders: Classification with Machine Learning.

Electroretinograms (ERGs) show differences between typically developing populations and those with a diagnosis of autism spectrum disorder (ASD) or attention deficit/hyperactivity disorder (ADHD). In a series of ERGs collected in ASD ( = 77), ADHD ( = 43), ASD + ADHD ( = 21), and control ( = 137) groups, this analysis explores the use of machine learning and feature selection techniques to improve the classification between these clinically defined groups. Standard time domain and signal analysis features were evaluated in different machine learning models.

In this study, basic fibroblast growth factor (bFGF)-Chitosan gel is injected into the stroke cavity.

Injectable Fluorescent Bottlebrush Polymers for Interventional Procedures and Biomedical Imaging.

Injectable biomaterials play a vital role in modern medicine, offering tailored functionalities for diverse therapeutic and diagnostic applications. In ophthalmology, for instance, viscoelastic materials are crucial for procedures such as cataract surgery but often leave residues, increasing postoperative risks.
