Objective: To develop and evaluate a Chinese version of the Symptom Questionnaire for Visual Dysfunctions (CSQVD) to quantify visual dysfunction symptoms in school-age children with various eye diseases, and to explore the relationship between ophthalmological disorders and visual dysfunction symptoms.

Methods: Following standard scale adaptation procedures, the Symptom Questionnaire for Visual Dysfunctions (SQVD) was translated into Chinese (CSQVD). We employed random sampling to survey 198 outpatients aged 7-18 to assess the psychometric properties of the CSQVD.

Purpose: To investigate gender disparities in the global burden of refractive disorders in children younger than 15 years by year, age, and national developmental status using disability-adjusted life years (DALYs).

Methods: Global, regional, and national gender-specific DALY numbers and rates of refractive disorders in children were obtained by year (from 1990 to 2019) and age group (0 to 4, 5 to 9, and 10 to 14 years) from the Global Burden of Disease Study 2019. Data from the Inequality-adjusted Human Development Index in 2019 as an indicator of national developmental status were extracted from the Human Development Report.

Fungal keratitis is one of the most common blindness-causing diseases, but clinical antifungal treatment remains a challenge. The fungal cell wall and biofilm matrix which severely confine the drug preparation are the critical obstructive factors to therapeutic effects. Herein, we report ethylenediaminetetraacetic acid (EDTA) modified AgCuO nanoparticles (AgCuE NPs) to disrupt the cell wall and then eradicate through the internal cascade synergistic effects of ion-released chemotherapy, chemodynamic therapy, photodynamic therapy, and mild photothermal therapy.

Background: Posterior capsule opacification (PCO) is the most common complication after cataract surgery, in which increased levels of transforming growth factor-beta 2 (TGF-β2) accelerate PCO formation; however, the pathological mechanisms are not fully understood. This study aims to explore the regulation mechanism of TGF-β2 in PCO formation via its autophagic functions.

Methods: The autophagic effect of TGF-β2 was detected by transmission electron microscopy (TEM), Western blotting, and immunofluorescence analysis.

In this study, we explored the role of necroptosis in the pathogenesis of ocular surface injury caused by airborne particulate matter (PM). Human corneal epithelial (HCE) cells and mouse ocular surface were treated with PM exposure and compared with non-exposed groups. The expression of necroptosis-related proteins was measured by immunoblotting in HCE cell groups.

Adherens junction remodeling regulated by apical polarity proteins constitutes a major driving force for tissue morphogenesis, although the precise mechanism remains inconclusive. Here, we report that, in zebrafish, the Crumbs complex component MPP5a interacts with small GTPase Rab11 in Golgi to transport cadherin and Crumbs components synergistically to the apical domain, thus establishing apical epithelial polarity and adherens junctions. In contrast, Par complex recruited by MPP5a is incapable of interacting with Rab11 but might assemble cytoskeleton to facilitate cadherin exocytosis.

Article Synopsis
  • The study aimed to identify a new gene mutation related to Waardenburg syndrome (WS), an inherited disorder causing hearing loss and pigmentation differences in the skin, hair, and eyes.
  • Genetic analysis of a Chinese family using whole-exome and Sanger sequencing revealed a novel mutation (c.638A>G) linked to WS type I characteristics, including significant hearing loss and distinct eye color.
  • This discovery adds to the genetic diversity associated with WS and highlights the necessity of recognizing ocular symptoms in all patients with the condition.

Oxidative stress-induced injury and apoptosis of human lens epithelial cells (HLECs) are early events in the development of age‑related cataracts (ARCs). Humanin (HN) is a mitochondrial‑related peptide that serves a cytoprotective role in various cell types and animal models. Following HN knockdown or overexpression, the level of reactive oxygen species (ROS), mitochondrial membrane potential and mitochondrial DNA copy number, cell viability, LDH activity and apoptosis of HLECs under oxidative stress were detected, and apoptosis and autophagy were detected via transmission electron microscopy.

Aim: To explore the susceptible association between the insulin-like growth factor-1 receptor (IGF1R) single nucleotide polymorphism (SNP) and age-related cataract (ARC), and investigate the underlying mechanisms in human lens epithelium (HLE) cells.

Methods: Totally 1190 unrelated participants, comprising 690 ARC patients and 500 healthy individuals in Han Chinese population were recruited and genotyped for target SNP. The -test was used to detect genotypic distribution between the patient and control groups and the logistic regression was performed to adjust the age and gender.

The gap junction protein alpha 8 (GJA8) gene has been widely studied in human congenital cataracts. However, little is known about its relationship with age-related cataract (ARC). In this study, three GJA8-tagged single nucleotide polymorphisms related to an increased ARC risk were identified: rs2132397 for general ARC under both dominant and additive models; rs7541950 for general ARC under both recessive and additive models; and rs6657114 for cortical cataract under the recessive model.

Background: We conducted this meta-analysis to compare the outcomes of coaxial microincision cataract surgery (C-MICS) and standard coaxial small incision cataract surgery (C-SICS).

Methods: The outcomes of randomized controlled trials (RCTs) reporting C-MICS and C-SICS were collected from PubMed, Web of Science, and The Cochrane Library in May 2015. The final meta-analysis was conducted on the following intraoperative and postoperative outcomes: ultrasound time (UST), effective phacoemulsification time (EPT), balanced salt solution use (BSS use), cumulative dissipated energy (CDE), mean surgery time, endothelial cell loss percentage (ECL%), best corrected visual acuity (BCVA), increased central corneal thickness (CCT), laser flare photometry values and surgically induced astigmatism (SIA).
