Summary: The study investigated corneal biomechanical response parameters in varying degrees of myopia and their correlation with corneal geometrical parameters and axial length. The results showed significant relationships between corneal biomechanical parameters with level of myopia, indicating a progressive reduction in corneal stiffness with increasing myopia, independent of IOP and CCT. Dynamic corneal response assessed by Corvis ST indicates biomechanical changes consistent with decreasing stiffness with increasing levels of myopia.

Summary: This study investigated the association between SNTB1 and ZFHX1B gene polymorphisms and high myopia in a Northern Han Chinese population. The results showed that the G-C-A-G haplotype in SNTB1 and the minor T allele of ZFHX1B rs13382811 were both associated with an increased risk of high myopia.

Summary: This study aimed to investigate the association between choroidal thickness and age, axial length, and refractive errors in Chinese adults. The results showed that choroidal thickness decreased with age after 50 years, and the thinning was more prominent in the central and parafoveal regions as axial length increased. The correlation between choroidal thickness and age and axial length varied among different groups with different refractive errors.

Summary: This study investigated the associations of SNPs in the MTOR and PDGFRA genes with different degrees of myopia severity. The results showed that rs1057079 and rs1064261 were associated with mild to moderate myopia. However, the association of rs1057079 could not withstand multiple correction. Patients carrying more adverse genotypes had a higher risk of myopia. The Zhuang population consistently had a higher frequency of myopia.

Summary: This study identified genetic variants of crucial ERK signaling pathway genes that were significantly correlated with myopia and ocular parameter alterations in Chinese children. A combination of gene and miRNA functional analyses with enrichment analyses highlights the regulatory effects associated with ocular development and dopamine biological functions. This study offers novel clues to understand the role of dopamine in the molecular mechanisms of myopia.

Summary: This study found that the changes in miRNAs, cytokines, and neutralizing activity in the saliva and plasma of COVID-19 patients are associated with disease severity. Compared to mild patients, severe patients showed significant differences in the expression of 8 miRNAs in their saliva and plasma, with increased expression of immune regulatory miRNAs and decreased expression of others.

Summary: This study found that SNPs in ZFHX1B, KCNQ5, and GJD2 are associated with myopia progression in children. Children with a high-risk PRS defined by GJD2 rs524952, KCNQ5 rs7744813, and ZFHX1B rs13382811 had a 2.26-fold increased risk of fast myopia progression.

Summary: This study explored the relationship between choroid vascular index (CVI) and best corrected visual acuity (BCVA) in patients with high myopia (HM). The results showed that CVI is significantly correlated with BCVA and is not affected by age, axial length, or spherical equivalent (SE), suggesting that CVI could be used as an adjunct tool for assessing visual acuity in patients with HM.

Summary: This study investigates the association between retinal sensitivity and microstructural features in optical coherence tomography (OCT) of highly myopic eyes. The results showed that retinal sensitivity was significantly associated with the integrity of the retinal pigment epithelium (RPE), ellipsoid zone (EZ), and external limiting membrane (ELM) based on OCT. The severity of myopic maculopathy and proximity to patchy atrophy lesion also affected retinal sensitivity and microstructure.

Summary: The COVID-19 pandemic caused by SARS-CoV-2 has had a significant impact worldwide. This study aimed to investigate the clinical characteristics of COVID-19 children with different severities and allergic status. The results showed that pediatric COVID-19 patients tend to have a mild clinical course, with pneumonia patients showing higher levels of fever, cough, and inflammatory biomarkers. Allergic and nonallergic COVID-19 children did not differ significantly in terms of disease incidence, clinical features, and laboratory and immunological findings.

Summary: The severity of COVID-19 is associated with dysregulation of immune response and metabolic reprogramming. Molecular pathophysiological heterogeneity was observed in moderate COVID-19 patients. Protein-level alterations during disease progression showed that proteins involved in complement activation, coagulation cascade, and cholesterol metabolism recovered at the convalescence stage, except for some proteins such as anti-angiogenesis protein PLGLB1.

Summary: The study aims to identify normative values and determinants for Bruch's membrane opening (BMO) and the minimum rim width of BMO (BMO-MRW) among healthy children. The results indicate that BMO-MRW increases with age among children and other factors such as the thickness of the optic nerve head and peripapillary retinal nerve fiber layer also have an impact on BMO parameters.

Summary: This study compared the prevalence of different types of astigmatism in Hong Kong children and adults and evaluated the role of internal astigmatism in compensating for total astigmatism and its association with myopic traits. The results showed that Chinese children in Hong Kong have a higher prevalence of refractive astigmatism and corneal astigmatism compared to other cities. Children also exhibited a greater compensation by internal astigmatism than adults, suggesting an age-related attenuation of internal astigmatism compensation. Internal astigmatism was found to be associated with myopic traits.

Summary: DIVE is a digital tool with an integrated eye tracker that automates the visual assessment process in preverbal children. This study evaluated the development of visual acuity and contrast sensitivity using DIVE in a large sample of children and found that both improved throughout childhood. The results also showed no significant differences between preterm and full-term children.

Summary: Our study aims to develop a deep learning system (DLS) that can identify children at risk of developing high myopia and predict its development by teenage years. We train and validate the DLS using a school-based cohort in Singapore and achieve clinically acceptable performance with image, clinical, and mixed models. The addition of a 1-year progression variable has minimal impact on the DLS performance.

Summary: This study aimed to evaluate the habitual reading distance among non-myopic children and also myopic children with undercorrection and with full correction. The results showed that undercorrected myopic children had the shortest reading distance, while there was no significant difference between non-myopic children and fully corrected myopic children. A shorter reading distance was associated with myopia, but this association did not hold after undercorrected myopic children were excluded.

Summary: This study evaluates the ability of GPT-4 to identify rare ophthalmic diseases in simulated scenarios. The results show that GPT-4's responses were considered appropriate in most cases, but it still has limitations in accurately diagnosing rare eye diseases. Despite its potential as a consultation assisting tool for patients, family physicians, and junior ophthalmologists, caution and verification are necessary in clinical settings.

Summary: This study conducted a systematic review to summarize the effects of physical exercise on mental health, cognitive function, and ADHD symptoms in children and adolescents with ADHD. The results showed a strong recommendation for the effectiveness of exercise in improving attention, inhibitory control, and cognitive flexibility, but weak evidence for emotional functioning, social functioning, and working memory.
