ABSTRACT

Purpose: Microphthalmia is a rare developmental eye disease that affects 1 in 7000 births. Currently, there is no cure for this condition. This study aimed to construct a stable mouse model of microphthalmia, thus providing a new tool for the study of the etiology of microphthalmia. Methods: The Hedgehog signaling pathway plays a crucial role in eye development. One of the key mechanisms of the Sonic Hedgehog signaling is the strong transcriptional activation ability of GLI3, a major mediator of this pathway. This study used CRISPR/Cas9 system to construct a novel TgGli3Ki/Ki lens-specific over-expression mouse line. To identify the ocular characteristics of this line, quantitative PCR, Western blot, hematoxylin and eosin staining, immunofluorescent staining, and RNA-seq were performed on the ocular tissues of this line and normal mice. Results: The TgGli3Ki/Ki lens-specific over-expression mouse model exhibits the ocular phenotype of microphthalmia. In the TgGli3Ki/Ki mouse, Gli3 is over-expressed in the lens, and the size of the eyeball and lens is significantly smaller than the normal one. RNA-seq analysis using the lens and the retina samples from TgGli3Ki/Ki and normal mice indicates that the phototransduction pathway is ectopically activated in the lens. Immunofluorescent staining of the lens samples confirmed this activation. Conclusions: The TgGli3Ki/Ki mouse model consistently manifests the stereotypical microphthalmia phenotype across generations, making it an excellent tool for studying this severe eye disease. Translational Relevance: This study developed a novel animal model to facilitate clinical research on microphthalmia.

ABSTRACT

There is a knowledge gap concerning the proper timing for COVID-19 vaccination in cancer patients undergoing chemotherapy. We aimed to evaluate the suitability of the guidelines that recommend waiting at least three months after undergoing chemotherapy before receiving a COVID-19 vaccine. This retrospective cohort study used aggregated data from the TriNetX US Collaboratory network. Participants were grouped into two groups based on the interval between chemotherapy and vaccination. The primary outcome assessed was infection risks, including COVID-19; skin, intra-abdominal, and urinary tract infections; pneumonia; and sepsis. Secondary measures included healthcare utilization and all causes of mortality. Kaplan-Meier analysis and the Cox proportional hazard model were used to calculate the cumulative incidence and hazard ratio (HR) and 95% confidence intervals for the outcomes. The proportional hazard assumption was tested with the generalized Schoenfeld approach. Four subgroup analyses (cancer type, vaccine brand, sex, age) were conducted. Sensitivity analyses were performed to account for competing risks and explore three distinct time intervals. Patients receiving a vaccine within three months after chemotherapy had a higher risk of COVID-19 infection (HR: 1.428, 95% CI: 1.035-1.970), urinary tract infection (HR: 1.477, 95% CI: 1.083-2.014), and sepsis (HR: 1.854, 95% CI: 1.091-3.152) compared to those who adhered to the recommendations. Hospital inpatient service utilization risk was also significantly elevated for the within three months group (HR: 1.692, 95% CI: 1.354-2.115). Adhering to a three-month post-chemotherapy waiting period reduces infection and healthcare utilization risks for cancer patients receiving a COVID-19 vaccine.

ABSTRACT

The human PLAA gene encodes Phospholipase-A2-Activating-Protein (PLAA) involved in trafficking of membrane proteins. Through its PUL domain (PLAP, Ufd3p, and Lub1p), PLAA interacts with p97/VCP modulating synaptic vesicles recycling. Although few families carrying biallelic PLAA variants were reported with progressive neurodegeneration, consequences of monoallelic PLAA variants have not been elucidated. Using exome or genome sequencing we identified PLAA de-novo missense variants, affecting conserved residues within the PUL domain, in children affected with neurodevelopmental disorders (NDDs), including psychomotor regression, intellectual disability (ID) and autism spectrum disorders (ASDs). Computational and in-vitro studies of the identified variants revealed abnormal chain arrangements at C-terminal and reduced PLAA-p97/VCP interaction, respectively. These findings expand both allelic and phenotypic heterogeneity associated to PLAA-related neurological disorders, highlighting perturbed vesicle recycling as a potential disease mechanism in NDDs due to genetic defects of PLAA.

ABSTRACT

Drug abuse is a severe social problem worldwide. Particularly, the issue of new psychoactive substances (NPSs) have increasingly emerged. NPSs are structural or functional analogs of traditional illicit drugs, such as cocaine, cannabis, and amphetamine; these molecules provide the same or more severe neurological effects. Usually, immunoassays are utilized in the preliminary screening method. However, NPSs have poor detectability in commercially available immunoassay kits. Meanwhile, various chromatography combined with the mass spectrometry platform have been developed to quantify NPSs. Still, a significant amount of time and resources are required during these procedures. Therefore, we established a rapid analytical platform for NPSs employing paper-loaded direct analysis in real time triple quadrupole mass spectrometry (pDART-QqQ-MS). We implemented this platform for the semiquantitative analysis of forensic drug tests in urine. This platform significantly shrinks the analytical time of a single sample within 30 s and requires a low volume of the specimen. The platform can detect 21 NPSs in urine mixtures at a lower limit of qualification of concentration ranging from 20 to 75 nanograms per milliliter (ng mL-1) and is lower than the cutoff value of currently available immune-based devices for detecting multiple drugs (1000 ng mL-1). Urine samples from drug addicts have been collected to verify the platform's effectiveness. By combining efficiency and accuracy, our platform offers a promising solution for addressing the challenges posed by NPSs in drug abuse detection.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: The Compendium of Materia Medica and the Classic of Materia Medica, the two most prominent records of traditional Chinese medicine, documented the therapeutic benefits of Ganoderma sinense particularly in addressing pulmonary-related ailments. Ganoderma formosanum, an indigenous subspecies of G. sinense from Taiwan, has demonstrated the same therapeutic properties. AIM OF THE STUDY: The aim of this study is to identify bioactive compounds and evaluate the potential of G. formosanum extracts as a novel treatment to alleviate pulmonary fibrosis (PF). Using an in-house drug screening platform, two-stage screening was performed to determine their anti-fibrotic efficacy. METHODS AND MATERIALS: G. formosanum was fractionated into four partitions by solvents of different polarities. To determine their antifibrotic and pro-apoptotic properties, the fractions were analyzed using two TGF-ß1-induced pulmonary fibrosis cell models (NIH-3T3) and human pulmonary fibroblast cell lines, immunoblot, qRT-PCR, and annexin V assays. Subsequently, transcriptomic analysis was conducted to validate the findings and explore possible molecular pathways. The identification of potential bioactive compounds was achieved through UHPLC-MS/MS analysis, while molecular interaction study was investigated by multiple ligands docking and molecular dynamic simulations. RESULTS: The ethyl acetate fraction (EAF) extracted from G. formosanum demonstrated substantial anti-fibrotic and pro-apoptotic effects on TGF-ß1-induced fibrotic models. Moreover, the EAF exhibited no discernible cytotoxicity. Untargeted UHPLC-MS/MS analysis identified potential bioactive compounds in EAF, including stearic acid, palmitic acid, and pentadecanoic acid. Multiple ligands docking and molecular dynamic simulations further confirmed that those bioactive compounds possess the ability to inhibit TGF-ß receptor 1. CONCLUSION: Potential bioactive compounds in G. formosanum were successfully extracted and identified in the EAF, whose anti-fibrotic and pro-apoptotic properties could potentially modulate pulmonary fibrosis. This finding not only highlights the EAF's potential as a promising therapeutic candidate to treat pulmonary fibrosis, but it also elucidates how Ganoderma confers pulmonary health benefits as described in the ancient texts.

ABSTRACT

INTRODUCTION: While retail sales and retailer inspection studies generally indicate high compliance with state sales restrictions on Nicotine Vaping Products (NVPs) within the restricted area, studies using survey data generally indicate that most users could readily continue gaining access to restricted NVPs. Our study bridges a gap in the current literature and investigates the potential role of cross-state border purchases to evade state emergency NVP sales restrictions in 2019. METHODS: The study sample was restricted to NVP sales from the states neighboring Massachusetts (MA), Rhode Island (RI), and Washington (WA), three states that implemented all NVP or flavored NVP sales restrictions in 2019. Among these neighboring states, the 2019 weekly county-level NVP sales by flavors (tobacco, mint/menthol, and other flavors) were compiled using Nielsen Scanner data. A quasi-experimental, comparison group pre-post study design was used to study the impacts of NVP sales restrictions on cross-state border NVP purchases. RESULTS: Weekly NVP sales for border counties significantly increased in response to the MA, RI, and WA bans for tobacco flavored (56%, 45%, 14%, respectively), menthol/mint flavored (51%, 2%, 41%, respectively), and other flavored (79%, 3%, 4%, respectively) products, compared to sales for non-border counties (all p-values <0.01). CONCLUSIONS: Our study identified significant cross-state border NVP purchases in all studied states to circumvent NVP emergency sales restrictions in response to the EVALI outbreak. Policymakers should factor in these purchasing behaviors to evade sales restrictions when evaluating any future potential policies at the state or local levels. IMPLICATIONS: While retail sales data and retailer inspections indicate high compliance with Nicotine Vaping Product (NVP) flavor sales restrictions from major retail outlets, survey data obtain mixed findings on the effects of sales restrictions on vaping behaviors. Our study identified a significant increase in cross-state border NVP purchases to circumvent NVP sales restrictions in 2019, consistent across all three settings of Massachusetts, Rhode Island, and Washington. Policymakers should factor in these cross-state border NVP purchases in response to sales restrictions when evaluating any future potential NVP sales restrictions.

ABSTRACT

PURPOSE: To investigate the efficacy of combined application of B-scan ultrasonography (US) and ultrawide field imaging (UWFI) in detecting retinal tears before cataract surgery. METHODS: Of 1,277 cataract patients, 2,552 eyes were enrolled and received both B-scan US and UWFI examinations preoperatively. Three types of combination were applied: type 1 (union, B-scan US or centered UWFI), type 2 (intersection, B-scan US and centered UWFI), and type 3 (B-scan US and eye-steering UWFI). Sensitivity and specificity of detecting retinal tears by different methods were assessed. RESULTS: Totally 4.55% (116/2,552) of eyes were presented with retinal tears. The sensitivity of B-scan US and UWFI was 87.93% and 84.48%, and specificity was 95.16% and 99.79%, respectively. By applying type 1 and type 2 combination, the sensitivity was 98.28% and 74.14%, and specificity was 95.03% and 99.92%, respectively. By type 3 combination, the sensitivity increased to 95.69% and specificity to 99.88%, both of which were comparable to indirect ophthalmoscopy regardless of the number, type, and location of tears ( P > 0.05). In eyes with any cataract type or axial length, type 3 combination also gained comparable performance to indirect ophthalmoscopy. CONCLUSION: Combined application of B-scan US and eye-steering UWFI presented satisfactory performance in detecting retinal tears before cataract surgery.

ABSTRACT

Tumor metastasis and cancer recurrence are often a result of cell heterogeneity, where specific subpopulations of tumor cells may be resistant to radio- or chemotherapy. To investigate this physiological and phenotypic diversity, single-cell metabolomics provides a powerful approach at the chemical level, where distinct lipid profiles can be found in different tumor cells. Here, we established a highly sensitive platform using nanoflow liquid chromatography (nLC) combined with multinozzle emitter electrospray ionization mass spectrometry for more in-depth metabolomics profiling. Our platform identified 15 and 17 lipids from individual osteosarcoma (U2OS) and glioblastoma (GBM) cells when analyzing single-cell samples. Additionally, we used the functional single-cell selection (fSCS) pipeline to analyze the subpopulations of cells with a DNA damage response (DDR) in U2OS cells and fast migration in GBM cells. Specifically, we observed a down-regulation of polyunsaturated fatty acids (PUFAs) in U2OS cells undergoing DDR, such as fatty acids FA 20:3; O2 and FA 17:4; O3. Furthermore, ceramides (Cer 38:0; O3) and triglycerides (TG 36:0) were found to be down-regulated in fast-migrating GBM cells compared to the slow-migrating subpopulation. These findings suggest the potential roles of these metabolites and/or lipids in the cellular behavior of the subpopulations.

ABSTRACT

OBJECTIVE: Telemedicine can facilitate social distancing during an infectious disease pandemic and reduce the burden on health-care resources. Moreover, telemedicine can be utilized for medical care in remote island regions, in home health care, and during isolated major disasters such as regional earthquakes. However, the effectiveness of telemedicine for emergency consultation remains unclear. This study introduced and analyzed the national emergency medical teleconsultation (NEMTC) established in Taiwan in 2022 during the COVID-19 pandemic. METHODS: In response to the COVID-19 pandemic, Taiwan's Centers for Disease Control established a temporary 24-h NEMTC contingency system. Patient information was collected from consultations through the NEMTC from April 28 to June 28, 2022. After successful consultation, physicians made recommendations for home observation, emergency department (ED) visit, or outpatient follow-up. ED visits were divided into two categories, namely self-transport and transport, by the emergency medical service system (EMSS). RESULTS: During the aforementioned period, 20,902 consultation requests were made through the NEMTC, and 11,804 consultations (56.5% of 20,902) were successful. Consultation success rates were significantly higher for those who had a consultation between 08:00 and 16:00, had a waiting time of less than 10 min, and were not aged between 18 and 45 years. Moreover, 8.2% of the analyzed patients were advised to visit the ED, and only 0.4% required ambulance transportation. Children and older individuals and patients with cardiovascular symptoms, shortness of breath, or neurological or abdominal symptoms had a significantly higher chance of being referred to the ED than did other individuals. CONCLUSIONS: The NEMTC response system can enhance the efficiency of the EMSS and can reduce the burden of patients with mild conditions overloading the EMSS and EDs. The NEMTC could serve as an effective rapid response system during future pandemics.

ABSTRACT

The effect of physical activity (PA) on academic achievement has long been a hot research issue in physical education, but few studies have been conducted using machine learning methods for analyzing activity behavior. In this paper, we collected the data on both physical activity and academic performance from 2,219 undergraduate students (Mean = 19 years) over a continuous period of 12 weeks within one academic semester. Based on students' behavioral indicators transformed from a running APP interface and the average academic course scores, two models were constructed and processed by CHAID decision tree for regression analysis and significance detection. It was found that first, to attain higher academic performance, it is imperative for students to not only exhibit exceptional activity regularity, but also sustain a reduced average step frequency; second, the students completing running exercise with an average frequency of 1 time/week and the duration of 16-25 min excelled over approximately 88 percentage of other students on academic performance; third, the processing validity and reliability of physical observation data in complex systems can be improved by utilizing decision tree as a leveraging machine learning tool and statistical method. These findings provide insights for educational practitioners and policymakers who will seek to enhance college students' academic performance through physical education programs, combined with data mining methods.

ABSTRACT

Decoding brain activity is conducive to the breakthrough of brain-computer interface (BCI) technology. The development of artificial intelligence (AI) continually promotes the progress of brain language decoding technology. Existent research has mainly focused on a single modality and paid insufficient attention to AI methods. Therefore, our objective is to provide an overview of relevant decoding research from the perspective of different modalities and methodologies. The modalities involve text, speech, image, and video, whereas the core method is using AI-built decoders to translate brain signals induced by multimodal stimuli into text or vocal language. The semantic information of brain activity can be successfully decoded into a language at various levels, ranging from words through sentences to discourses. However, the decoding effect is affected by various factors, such as the decoding model, vector representation model, and brain regions. Challenges and future directions are also discussed. The advances in brain language decoding and BCI technology will potentially assist patients with clinical aphasia in regaining the ability to communicate.

ABSTRACT

The sterilisation of surgical instruments is a major factor in infection control in the operating room (OR). All items used in the OR must be sterile for patient safety. Therefore, the present study evaluated the effect of far-infrared radiation (FIR) on the inhibition of colonies on packaging surface during the long-term storage of sterilised surgical instruments. From September 2021 to July 2022, 68.2% of 85 packages without FIR treatment showed microbial growth after incubation at 35 °C for 30 days and at room temperature for 5 days. A total of 34 bacterial species were identified, with the number of colonies increasing over time. In total, 130 colony-forming units were observed. The main microorganisms detected were Staphylococcus spp. (35%) and Bacillus spp. (21%) , Kocuria marina and Lactobacillus spp. (14%), and mould (5%). No colonies were found in 72 packages treated with FIR in the OR. Even after sterilisation, microbial growth can occur due to movement of the packages by staff, sweeping of floors, lack of high-efficiency particulate air filtration, high humidity, and inadequate hand hygiene. Thus, safe and simple far-infrared devices that allow continuous disinfection for storage spaces, as well as temperature and humidity control, help to reduce microorganisms in the OR.

ABSTRACT

INTRODUCTION: The purpose of this study was to evaluate the long-term outcomes of posterior capsular opacification (PCO) in highly myopic eyes and its influencing factors. METHODS: Patients undergoing phacoemulsification with intraocular lens implantation and followed up for 1-5 years were included in this prospective cohort study. The severity of PCO was evaluated using EPCO2000 software system, with the area of central 3.0 mm (PCO-3 mm) and within the capsulorhexis (PCO-C) both being analyzed. Percentage of eyes after Nd:YAG capsulotomy, as well as clinically significant PCO (defined as eyes with visual-impairing PCO or after capsulotomy), were also included as outcome variables. RESULTS: A total of 673 highly myopic eyes [axial length (AL) ≥ 26 mm] and 224 control eyes (AL < 26 mm) were analyzed. The mean follow-up time was 34.0 ± 9.0 months. PCO was more severe in highly myopic eyes compared with controls with regard to higher EPCO scores (P < 0.001 for both PCO-3 mm and PCO-C), higher capsulotomy rate (P = 0.001), higher clinically significant PCO rate (P < 0.001) and shorter PCO-free survival time (P < 0.001). Extreme myopia (AL ≥ 28 mm) would further aggravate PCO in terms of higher EPCO scores (PCO-3 mm: P = 0.017; PCO-C: P = 0.013) and higher clinically significant PCO rate (P = 0.024) compared with other myopic eyes. In highly myopic eyes, AL [odds ratio (OR) 1.124, P = 0.004] and follow-up duration (OR 1.082, P < 0.001) were independent risk factors for clinically significant PCO after cataract surgery. CONCLUSION: Highly myopic eyes had more severe PCO in the long term. Longer AL and follow-up duration were associated with higher risk of PCO. CLINICAL TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (NCT03062085).

ABSTRACT

The study utilized fresh fourth-day Chenopodium formosanum sprouts as the substrate for Rhizopus oligosporus fermentation. The resultant products showed higher antioxidant capacity than those from C. formosanum grains. Compared to traditional plate fermentation (PF), fermentation in a bioreactor (BF) (35 °C, 0.4 vvm aeration at 5 rpm) led to higher free peptide content (99.56 ± 7.77 mg casein tryptone/g) and enzyme activity (amylase, glucosidase, and proteinase are 2.21 ± 0.01, 54.57 ± 10.88, and 40.81 ± 6.52 U/g, respectively) than traditional plate fermentation (PF). Using mass spectrometry analysis, two peptides TDEYGGSIENRFMN and DNSMLTFEGAPVQGAAAITEK were predicted to possess high bioactive properties as DPP IV and ACE inhibitors. Additionally, over twenty new metabolites (aromatics, amines, fatty acids, and carboxylic acids) were discovered in the BF system compared to its PF counterpart. Results suggest that using a BF system to ferment C. formosanum sprouts is an appropriate method to scale-up fermentation and enhance nutritional values as well as bioactivities.

ABSTRACT

PURPOSE: To evaluate the long-term progression pattern of myopic tractional maculopathy and the risk factors. METHODS: The prevalence and grade of myopic tractional maculopathy were assessed with optical coherence tomography at enrollment and at the 2-year follow-up. The severity of posterior staphyloma and the presence of dome-shaped macula were also evaluated. RESULTS: In total, 610 highly myopic eyes of 610 patients were analyzed. The prevalence of epiretinal membrane, myopic retinoschisis, and macular hole increased from 26.7%, 12.1%, and 4.4% at enrollment to 41.1%, 18.2%, and 9.5% at the 2-year follow-up, respectively. Epiretinal membrane progressed in 21.8% of eyes, but visual acuity did not decline significantly in these eyes. Myopic retinoschisis progressed in 6.8% of eyes, and macular hole progressed in 14.8% of eyes. Significantly greater best-corrected visual acuity reduction was detected in the eyes with myopic retinoschisis or macular hole progression than the rest ( P < 0.05). Multivariate analysis showed that longer axial length, more-severe posterior staphyloma, and absence of dome-shaped macula were associated with myopic tractional maculopathy progression. CONCLUSION: In highly myopic eyes, long-term visual acuity was relatively stable in those with epiretinal membrane, but was significantly affected by myopic retinoschisis or macular hole progression. Longer axial length, more-severe posterior staphyloma, and absence of dome-shaped macula were risk factors for myopic tractional maculopathy progression.

ABSTRACT

Cell adhesion plays essential roles in almost every aspect of metazoan biology. LINKIN (Human: ITFG1, Caenorhabditis elegans: lnkn-1) is a conserved transmembrane protein that has been identified to be necessary for tissue integrity during migration. In C. elegans, loss of lnkn-1 results in the detachment of the lead migratory cell from the rest of the developing male gonad. Previously, three interactors of ITFG1/lnkn-1 - RUVBL1/ruvb-1, RUVBL2/ruvb-2, and alpha-tubulin - were identified by immunoprecipitation-mass spectrometry (IP-MS) analysis using human HEK293T cells and then validated in the nematode male gonad. The ITFG1-RUVBL1 interaction has since been independently validated in a breast cancer cell line model that also implicates the involvement of the pair in metastasis. Here, we showed that epitope-tagged ITFG1 localized to the cell surface of MDA-MB-231 breast cancer cells. Using IP-MS analysis, we identified a new list of potential interactors of ITFG1. Loss-of-function analysis of their C. elegans orthologs found that three of the interactors - ATP9A/tat-5, NME1/ndk-1, and ANAPC2/apc-2 - displayed migratory detachment phenotypes similar to that of lnkn-1. Taken together with the other genes whose reduction-of-function phenotype is similar to that of lnkn-1 (notably cohesion and condensin), suggests the involvement of membrane remodeling and chromosome biology in LINKIN-dependent cell adhesion and supports the hypothesis for a structural role of chromosomes in post-mitotic cells.

ABSTRACT

AIMS: To estimate whether and to what extent extending indoor smoking restrictions to include electronic cigarettes (ECs) impact the use of ECs and cigarette smoking among adults in the United States. DESIGN: Observational study using a linear probability model and applying a difference-in-differences analysis. SETTING: United States. PARTICIPANTS: People aged 18-54 who lived in US counties where comprehensive indoor smoking laws in bars, restaurants and private work-places have been in place prior to 2010 (n = 45 111 for EC use analysis, n = 75 959 for cigarette use analysis). MEASUREMENTS: Data on cigarette smoking, use of ECs and place of residence from the Tobacco Use Supplement of the Current Population Survey (TUS-CPS 2010-11, 2014-15 and 2018-19) were combined with the American Nonsmokers' Rights Foundation (ANRF) database of state and local indoor smoking and vaping restriction laws. FINDINGS: Indoor vaping restriction (IVR) coverage was not significantly associated with the likelihood of adult EC use [coefficient estimate = 0.001; 95% confidence interval (CI) = -0.009, 0.013, P-value = 0.783]. In addition, IVR coverage was not significantly associated with adult cigarette smoking (coefficient estimate = -0.00; 95% CI = -0.016, 0.015, P-value = 0.954). The non-significant results appeared in different socio-demographic subgroups. CONCLUSIONS: IVRs do not appear to decrease electronic cigarette use among US adults. There is no evidence that IVRs increase or decrease cigarette smoking among US adults.

ABSTRACT

Purpose: This study aims to explore the relationships between lens diameter (LD) measured with ultrasound biomicroscopy (UBM) and ocular biometric parameters. Methods: Ocular biometric parameters including axial length (AL), white-to-white distance (WTW), anterior chamber depth (ACD), lens thickness (LT) and anterior segment length (ASL) were measured with IOL-Master 700, and the direct measurement of LD was conducted through UBM (ArcScan Insight 100). Relationships between LD and ocular biometric parameters were then investigated. Eyes with AL ≥ 28 mm were defined as eyes with extreme myopia, and eyes with AL < 28 mm were defined as eyes without extreme myopia. Results: A total of 194 eyes from 194 subjects were included. The mean LD was 9.58 ± 0.49 mm, ranging from 8.60 to 10.96 mm. According to univariate analysis, larger LD was associated with elder age, male gender, larger WTW, ACD and ASL (all p < 0.05). Meanwhile, the LD was positively correlated with AL in eyes without extreme myopia (p < 0.05), but not in eyes with extreme myopia (p > 0.05). Backward stepwise regressions revealed that a larger LD was associated with larger WTW, ASL and AL in eyes without extreme myopia (all p < 0.05), while ASL was the only significant variable in eyes with extreme myopia (p < 0.05). Conclusion: Larger WTW, ASL and AL in eyes without extreme myopia, as well as longer ASL in eyes with extreme myopia indicated a larger LD, which provides guidance in personalized surgical choice and promises ideal visual outcomes.

ABSTRACT

Purpose: To assess the benefits of the cilioretinal artery on macular function in high myopia using the quantitative contrast sensitivity function (qCSF) method. Methods: This cross-sectional study was conducted at the Eye and Ear, Nose, and Throat Hospital of Fudan University. In total, 137 highly myopic patients (with axial length [AL] ≥ 26.00 mm) were enrolled and divided into cilioretinal artery absent and present groups based on their fundus photographs. One eye in each patient was randomly selected. Choroid thickness was measured using macular optical coherence tomography. The best-corrected visual acuity (BCVA) was evaluated by Early Treatment Diabetic Retinopathy Study charts, and the area under the log CSF (AULCSF), CSF acuity, and CS at six spatial frequencies were evaluated with the qCSF method. Results: Although no significant BCVA difference was found between the cilioretinal artery absent (97 patients) and present (40 patients) groups, choroid thickness, AULCSF, CSF acuity, and CSF at low and intermediate spatial frequencies (1-6 cycles per degree) were all significantly higher in the cilioretinal artery present group than in the absent group (all P < 0.05). In addition, eyes with temporal cilioretinal arteries exhibited significantly higher AULCSF, CSF acuity, and CSFs at 3 and 6 cycles per degree (all P < 0.05) than those with a nasal one (all P < 0.05). Multivariate analysis showed that better AULCSF was associated with the presence of cilioretinal artery and the interaction of AL and choroid thickness. Conclusions: The cilioretinal artery may associate with the larger choroid thickness in highly myopic eyes and may play a role in preserving qCSF outcomes, which are more sensitive than chart-based acuity tests.
