Downregulation of miR-127-5p promotes idiopathic epiretinal membrane development via GLUL-mediated Müller cell activation.

Idiopathic epiretinal membrane (iERM) represents a fibrocellular proliferation on retinal surface associated with vision loss, with underlying molecular mechanisms that remain undefined. The current work aimed to assess miR-127-5p for its role in the regulation of retinal Müller cell activity in iERM. We analyzed miRNA expression profiles in vitreous samples from iERM patients and controls.

Deep learning-based quantitative assessment inflammatory response of hyperreflective foci in diabetic macular edema.

Purpose: To investigate the associations between inflammatory cytokines (IL-6, ICAM-1, and VEGF), and hyperreflective foci (HRF) on spectral-domain optical coherence tomography (SD-OCT) in diabetic macular edema (DME).

Methods: Thirty-nine eyes from 29 patients with DME and 19 eyes from 19 control subjects were studied. Aqueous humor samples were measured using ELISA before anti-vascular endothelial growth factor therapy or cataract surgery.

From Monotherapy to Combination Strategies: Redefining Treatment Approaches for Multiple-Cause Macular Edema.

Macular edema (ME) is a leading cause of visual impairment in various retinal disorders. Current treatment modalities, including anti-vascular endothelial growth factor (anti-VEGF) agents and corticosteroids, often require repeated applications, increasing both medical and economic burdens. ME is driven by chronic inflammation and VEGF overexpression, causing fluid accumulation in the macula.

Clinical features evaluation of myopic fundus tessellation from OCTA and MfERG.

Purpose: To evaluate the differences in fundus tessellation among various severities using multifocal visual electrophysiology (MfERG) and optical coherence tomography angiography (OCTA) for clinical grading and treatment.

Methods: This study included 52 patients totaling 87 eyes. The Early Treatment Diabetic Retinopathy Study (ETDRS) grid division method was utilized to assess Grade of fundus tessellation.

Impact of visual impairments on cognitive functions in older adults: insights from NHANES data.

Background: Visual impairments (VI) are common in the older adults and may affect cognitive functions through mechanisms such as reduced sensory input and increased social isolation. Although current understanding of this association is incomplete, evidence suggests a potential link between poor vision and cognitive decline. This study aims to investigate the relationship between Subjective Visual Impairment (SVI), Objective Visual Impairment (OVI), and cognitive decline in the older adults, and assess whether these associations remain significant after controlling for multiple confounding factors.

Effects of organophosphorus flame retardant EHDPP on mouse retinal photoreceptor cells: Oxidative stress, apoptosis, and proinflammatory response.

2-Ethylhexyl diphenyl phosphate (EHDPP) is a frequently utilized organophosphorus flame retardant (OPFR) and has been extensively detected in environmental media. Prolonged daily exposure to EHDPP has been linked to potential retinal damage, yet the adverse impacts on the retina are still generally underexplored. In this research, we explored oxidative stress, inflammation, and the activating mechanisms initiated by EHDPP in mouse retinal photoreceptor (661 W) cells following a 24 h exposure period.

Application and progress of artificial intelligence technology in the segmentation of hyperreflective foci in OCT images for ophthalmic disease research.

With the advancement of retinal imaging, hyperreflective foci (HRF) on optical coherence tomography (OCT) images have gained significant attention as potential biological biomarkers for retinal neuroinflammation. However, these biomarkers, represented by HRF, present pose challenges in terms of localization, quantification, and require substantial time and resources. In recent years, the progress and utilization of artificial intelligence (AI) have provided powerful tools for the analysis of biological markers.

Epigenetic mechanism of SET7/9-mediated histone methylation modification in high glucose-induced ferroptosis in retinal pigment epithelial cells.

Ferroptosis of the retinal pigment epithelial (RPE) cells leads to retinal neuron injury and even visual loss. Our study aims to investigate the role of the SET domain with lysine methyltransferase 7/9 (SET7/9) in regulating high glucose (HG)-induced ferroptosis in RPE cells. The cell model was established by HG treatment.

Integrating Single-cell and Bulk RNA-seq to Construct a Metastasis-related Model for Evaluating Immunotherapy and Chemotherapy in Uveal Melanoma.

Background: Metastasis is a major cause of death in UM, highlighting the need to use highly specific and sensitive prognostic markers to identify patients with a risk of developing metastasis.

Aims: The aim of this study was to improve the current precision treatment for patients with metastatic uveal melanoma (UM).

Objective: The objective of this work was to investigate the heterogeneity between primary human UM and metastatic UM at the single-cell level and to discover potential molecules regulating UM metastasis.

Automated evaluation of retinal hyperreflective foci changes in diabetic macular edema patients before and after intravitreal injection.

Purpose: Fast and automated reconstruction of retinal hyperreflective foci (HRF) is of great importance for many eye-related disease understanding. In this paper, we introduced a new automated framework, driven by recent advances in deep learning to automatically extract 12 three-dimensional parameters from the segmented hyperreflective foci in optical coherence tomography (OCT).

Methods: Unlike traditional convolutional neural networks, which struggle with long-range feature correlations, we introduce a spatial and channel attention module within the bottleneck layer, integrated into the nnU-Net architecture.

Single-string, closed-loop fixation modification to reposit a dislocated triple-looped haptic intraocular lens.

A technique using the single-string, closed-loop fixation method to reposit dislocated triple-looped haptic intraocular lens (IOL)-capsular bag complex is described. The long needle or curved needle with a 10-0/8-0 polypropylene suture and a 27/30-gauge needle were used as the guide needle to pass through the fenestrated haptics twice. The scleral interlaminar course was used as the fixed point.
