Exposure to repetitive head impacts (RHI), such as those experienced in American football, is linked to cognitive dysfunction later in life. Traumatic encephalopathy syndrome (TES) is a proposed clinical syndrome thought to be linked to neuropath-ology of chronic traumatic encephalopathy (CTE), a condition associated with RHI from football. Cognitive intra-individual variability (d-CIIV) measures test-score dispersion, indicating cognitive dysfunction.

Reproducing the microstructure of the natural cornea remains a significant challenge in achieving the mechanical and biological functionality of artificial corneas. Therefore, the development of cascade structures that mimic the natural extracellular matrix (ECM), achieving both macro-stability and micro-structure, is of critical importance. This study proposes a novel, efficient, and general photo-functionalization strategy for modifying natural biomaterials.

Introduction: Optic disc drusen (ODD) are believed to have a genetic predisposition, with autosomal dominant inheritance pattern with incomplete penetrance suggested through family pedigree analysis. ODD prevalence is higher in certain genetic disorders, such as pseudoxanthoma elasticum and retinitis pigmentosa. This study aimed to identify candidate genes potentially involved in the development of ODD.

Can fundus features tell us something about 3D eye shape?

Ophthalmic Physiol Opt

January 2025

Robert O Curle Ophthalmology Suite, Institute for Regeneration and Repair, The University of Edinburgh, Edinburgh, UK.

Purpose: To determine whether imaging features derived from fundus photographs contain 3D eye shape information beyond that available from spherical equivalent refraction (SER).

Methods: We analysed 99 eyes of 68 normal adults in the UK Biobank. An ellipsoid was fitted to the entire volume of each posterior eye (vitreous chamber without the lens)-segmented from magnetic resonance imaging of the brain.

Background: Studies regarding hypercoagulation in Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) patients have produced conflicting results. With a presumption that the early coagulation phase may affect the occurrence of NAION, this study aims to investigate the early coagulation markers, E-selectin and P-selectin, to determine whether these biomolecular changes play a significant role in NAION, thus potentially leading to a better clinical approach.

Methods: A cross-sectional study involving two groups of NAION subjects, a hypercoagulation group and a non-hypercoagulation group, was conducted in the Neuro-Ophthalmology Division, Department of Ophthalmology, FKUI-RSCM Kirana from October 2020 to April 2022.

Optimizing autonomous artificial intelligence diagnostics for neuro-ocular health in space missions.

Life Sci Space Res (Amst)

February 2025

Human-Machine Perception Laboratory, Department of Computer Science and Engineering, University of Nevada, Reno, Reno, NV, United States.

Spaceflight-Associated Neuro-Ocular Syndrome (SANS) presents a critical risk in long-duration missions, with microgravity-induced changes that threaten astronaut vision and mission outcomes. Current SANS monitoring, limited to pre- and post-flight exams, lacks in-flight diagnostics, highlighting an urgent need for autonomous tools capable of real-time assessment. Grok, an AI platform by xAI, offers promising potential as an advanced diagnostic tool for space-based health monitoring.

With increasing advancements and efforts towards space exploration, there is a pressing need to understand the impacts of spaceflight on astronauts' health. Astronauts have reported signs and symptoms of dry eye disease upon traveling to the International Space Station (ISS), thus necessitating an evaluation of the factors that contribute to the onset of spaceflight associated dry eye disease. Prior literature describes the hypercapnic environment of the ISS; however, the link between the high CO levels and astronauts' symptoms of dry eye disease remains unexplored.

Purpose: In this study, it was planned to compare the macular ganglion cell analysis (GCA) and peripapillary retinal nerve fiber layer (pRNFL) of the patients with preperimetric glaucoma (PPG), early stage glaucoma (EG) and the control group.

Methods: This retrospective study included a total of 103 eyes: 38 from EG patients, 30 from PPG patients, and 35 from healthy individuals at Ankara Bilkent City Hospital Glaucoma Unit between January 2018 and September 2021. Eyes were categorized into control, PPG, and EG groups based on visual field (VF) classification.

Baseline and outcome stereoacuity of children with anisometropic amblyopia undergoing dichoptic amblyopia treatment.

J AAPOS

January 2025

Pediatric Vision Laboratory, Retina Foundation of the Southwest, Dallas, Texas; Optometry & Vision Science, University of Waterloo, Waterloo, Ontario, Canada.

Background: One rationale for dichoptic amblyopia therapy is that it may promote recovery of binocular function. Yet data on binocular outcomes in anisometropic amblyopia following dichoptic therapy are sparse. We report factors associated with pre- and post-treatment binocular function in anisometropic amblyopia, and examine binocular function in children who recover normal visual acuity compared to those with residual amblyopia.

Neovascular age-related macular degeneration and diabetic macular edema are leading causes of vision-loss evoked by retinal neovascularization and vascular leakage. The glycoprotein microfibrillar-associated protein 4 (MFAP4) is an integrin αβ ligand present in the extracellular matrix. Single-cell transcriptomics reveal MFAP4 expression in cell-types in close proximity to vascular endothelial cells including choroidal vascular mural cells and retinal astrocytes and Müller cells.

A multicenter study of neurofibromatosis type 1 utilizing deep learning for whole body tumor identification.

NPJ Digit Med

January 2025

Neurofibromatosis Type 1 Center and Laboratory for Neurofibromatosis Type 1 Research, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, 200011, China.

Deep-learning models have shown promise in differentiating between benign and malignant lesions. Previous studies have primarily focused on specific anatomical regions, overlooking tumors occurring throughout the body with highly heterogeneous whole-body backgrounds. Using neurofibromatosis type 1 (NF1) as an example, this study developed highly accurate MRI-based deep-learning models for the early automated screening of malignant peripheral nerve sheath tumors (MPNSTs) against complex whole-body background.
