Association of accommodation and convergence with axial length elongation in children with basic intermittent exotropia: a 12-month observational study.

INTRODUCTION: To investigate the association of parameters related to accommodation and convergence and axial elongation in basic intermittent exotropia (IXT) patients and the potential clinical predictors of axial length (AL) growth. METHODS: A total of 140 basic IXT patients were recruited in this study. The medians of AL growth in different age brackets were chosen to divide the subjects into Group A (slower axial elongation group, n=69) and Group B (faster axial elongation group, n=71). Parameters of dominant and nondominant eyes were compared and analyzed during the 12-month follow-up period. The parameters, including baseline refraction, angle of deviation, Newcastle score (NCS), accommodative amplitude (AMP), accommodative facility (AMF), accommodative response, positive or negative relative accommodation (PRA/NRA), and near point of convergence (NPC), were analyzed via univariate and multivariate regression. RESULTS: Subjects in faster axial elongation group tended to have more myopic spherical equivalents (t=3.956, P<.001), greater accommodative amplitudes of dominant eyes (t=-2.238, P=.027) and less near points of convergence (t=2.347, P=.020) than in slower axial elongation group. For dominant eyes, logistic and linear regression analysis revealed that more negative spherical equivalents (OR=0.603, P<.001; ß=-0.045, P<.001), greater accommodative amplitudes (OR=1.201, P=.027; ß=0.023, P=.010) and less near points of convergence (OR=0.883, P=.021; ß=-0.012, P=.019) were correlated with the faster axial elongation. For nondominant eyes, more myopic spherical equivalent (OR=0.682; P=.001; ß=-0.029, P=.005) was the only parameter correlated with faster axial elongation through regression analysis. CONCLUSION: In children with basic intermittent exotropia, faster axial elongation in the dominant eyes were associated with more myopic spherical equivalents, greater accommodative amplitudes, and lower near points of convergence. These accommodative parameters can serve as potential clinical indicators for monitoring myopia progression in addition to axial length.

The role and regulatory mechanism of FSCN1 in breast tumorigenesis and progression.

FSCN1, an actin-bundling protein, is highly expressed in almost all metastatic tumors and is associated with the poor prognosis. In breast cancer FSCN1 is highly expressed in basal-like and triple negative subgroups. There is significant progress in understanding the role of fascin in breast cancer. Studies on FSCN1 in recent years have revealed that FSCN1 not only promotes tumor migration, invasion, metastic colonization, cancer cell self-renewal and drug resistance, but also regulates glucose and lipid metabolism and mitochondrial remodeling in tumor cells. In this review, we focus on the structure and regulatory mechanism of FSCN1 in breast tumorigenesis and metastasis, and discuss the clinical value of FSCN1 with the aim to provide a direction for further research in this field.

Platycodin D ameliorates hyperglycaemia and liver metabolic disturbance in HFD/STZ-induced type 2 diabetic mice.

In this work, we investigated the ameliorative effects of platycodin D (PD), a major active chemical ingredient isolated from the roots of Platycodon grandiflorum (PG), on high-fat diet (HFD)/streptozotocin (STZ)-induced type 2 diabetes (T2D) mice. PD treatment (2.5 and 5.0 mg kg-1) improved HFD-induced body weight gain. PD administration also decreased the fasting blood glucose (FBG) level and improved glucose and insulin tolerance levels. These data collectively showed that PD could maintain glucose homeostasis. In addition, the diabetic mice with PD treatment also showed fewer pathological changes in liver tissues and improved hepatic functional indexes with respect to the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and recovery of abnormal liver function caused by T2D. Except for these, PD decreased the decomposition of hepatic glycogen. The results from western blot analysis showed that PD treatment might regulate the hepatic gluconeogenesis pathway with the increased phosphorylation/expression of AMPK and decreased expressions of PCK1 and G6Pase. In the aspect of lipid metabolism, PD decreased the whole-body lipid levels, including total cholesterol (TC), triglycerides (TG), and high-density lipoprotein (HDL), and reduced the hepatic fat accumulation induced by T2D through the AMPK/ACC/CPT-1 fatty acid anabolism pathway. In addition, the results of molecular docking showed that PD may have a potential direct effect on AMPK and other key glycolipid metabolism proteins. To summarize, PD modulation of hepatic glycolipid metabolism abnormalities is promising for T2D therapy in the future.

Saponins From Platycodon grandiflorum Reduces Cisplatin-Induced Intestinal Toxicity in Mice through Endoplasmic Reticulum Stress-Activated Apoptosis.

Saponins from the roots of Platycodon grandiflorum, an edible medicinal plant, have shown a wide range of beneficial effects on various biological processes. In this study, an animal model was established by a single intraperitoneal injection of cisplatin (20[Formula: see text]mg/kg) for evaluating the protective effects of saponins from the roots of P. grandiflorum (PGS, 15[Formula: see text]mg/kg and 30[Formula: see text]mg/kg) in mice. The results indicated that PGS treatment for 10 days restored the destroyed intestinal mucosal oxidative system, and the loosened junctions of small intestinal villi was significantly improved. In addition, a significant mitigation of apoptotic effects deteriorated by cisplatin exposure in small intestinal villi was observed by immunohischemical staining. Also, western blot showed that PGS could effectively prevent endoplasmic reticulum (ER) stress-induced apoptosis caused by cisplatin in mice by restoring the activity of PERK (an ER kinase)-eIF2[Formula: see text]-ATF4 signal transduction pathway. Furthermore, molecular docking results of main saponins in PGS suggested a better binding ability with target proteins. In summary, the present work revealed the underlying protective mechanisms of PGS on intestinal injury induced by cisplatin in mice.

The association of child neglect with lifestyles, depression, and self-esteem: Cross-lagged analyses in Chinese primary schoolchildren.

Child neglect robustly predicts many behavioral problems and adulthood mental disorders, but little is known about its association with daily lifestyles and psychological development during childhood, particularly in the longitudinal study. We aimed to examine the association of child neglect with physical activity (PA), screen time (ST), eating habits (EHs), and depression/self-esteem using a two-wave follow-up study of primary schoolchildren in Wuhan, China. Data of 1085 schoolchildren aged 8-10 years (boys: 53.5%) were analyzed. Child neglect, lifestyles, and depression/self-esteem were collected in 2018 (T1) and 2019 (T2). Autoregressive cross-lagged models (ARCLMs) were fitted to explore the interrelationships among these variables. In ARCLM including child neglect and lifestyles, higher child neglect at T1 was significantly associated with higher ST and more risky EHs at T2, while insignificantly associated with PA. In ARCLM including child neglect and depression/self-esteem, lower T1 child neglect significantly predicted a higher T2 depression, but insignificantly for T2 self-esteem. In ARCLM including all variables, child neglect still significantly predicted later ST and depression, but insignificantly predicted EHs. Our study underscores that child neglect is strongly intertwined with ST, EHs, and depression during childhood. The prevention of child neglect may promote some healthy lifestyles and depression in children.

The PI3K/Akt and NF-κB signaling pathways are involved in the protective effects of Lithocarpus polystachyus (sweet tea) on APAP-induced oxidative stress injury in mice.

Acetaminophen (APAP)-induced acute liver injury (ALI) is a health issue that has gradually attracted attention, and is often regarded as a model of drug-induced hepatotoxicity. The leaves of Lithocarpus polystachyus Rehd. (named as "sweet tea", ST) usually serve as tea drink and folk medicine for healthcare in the southwest part of China. In previous reports, it has been proven to protect various animal models, except for APAP-induced liver injury model. Therefore, this study initially explored the protective effect of ST leaf extract (STL-E) on hepatotoxicity induced by APAP in ICR mice. STL-E of 50 and 100 mg kg-1 were given to each group for 7 days. ALI was intraperitoneally induced by APAP treatment (i.p. 250 mg per kg body weight). Biochemical markers, levels of inflammatory factors, histopathological staining and western blotting were used to analyze the inflammation and apoptosis of liver tissues. Interestingly, the treatment with STL-E significantly attenuated APAP-induced liver injury (p < 0.05). Moreover, STL-E partially mitigated APAP-induced liver injury by effectively activating the PI3K/Akt pathway and inhibiting the NF-κB pathway. In a word, STL-E protected liver against APAP-induced hepatotoxicity by inhibiting the PI3K/Akt-mediated apoptosis signal pathway and inhibiting the NF-κB-mediated signaling pathway.

MiR-142-3p functions as a tumor suppressor by targeting RAC1/PAK1 pathway in breast cancer.

MicroRNA-142-3p (miR-142-3p) was previously investigated in various cancers, whereas, it's role in breast cancer (BC) remains far from understood. In this study, we found that miR-142-3p was markedly decreased both in cell lines and BC tumor tissues. Elevated miR-142-3p expression suppressed growth and metastasis of BC cell lines via gain-of-function assay in vitro and in vivo. Mechanistically, miR-142-3p could regulate the ras-related C3 botulinum toxin substrate 1 (RAC1) expression in protein level, which simultaneously suppressed the epithelial-to-mesenchymal transition related protein levels and the activity of PAK1 phosphorylation, respectively. In addition, rescue experiments revealed RAC1 overexpression could reverse tumor-suppressive role of miR-142-3p. Our results showed miR-142-3p could function as a tumor suppressor via targeting RAC1/PAK1 pathway in BC, suggesting a potent therapeutic target for BC treatment.

[MiR-30b Regulates the Cisplatin-Resistance of Human NK/T Cell Lypnphoma Cell Lines SNK-6 and YTS by Targeting the CCL22].

OBJECTIVE: To explore the effect and mechanism of miR-30b on cisplatin-resistance of human NK/T cell lymphoma lines SNK-6 and YTS cells. METHODS: Normal NK cells, SNK-6 and YTS cells were cultured, the expression levels of miR-30b and macrophage-derived chemokine (CCL22) were detected by real-time PCR assay, and the CCL22 expression was detected by Western blot. The SNK-6 and YTS cells were transfected with miR-30b mimics and inhibitor respectively, then the effect of cisplatin resistance in SNK-6 and YTS cells was measured by MTT assay, the activity of caspase-3 was detected by caspase-3 assay kit, and the cell apoptosis was analyzed by flow cytometry. Dual-luciferase reporter gene assay was used to determine the targeting relationship between miR-30b and CCL22. Furthermore, the effect of CCL22 on cisplatin-resistance and caspase-3 actirity was also evaluated. RESULTS: Compared with the normal NK cells, the expression levels of miR-30b significantly decreased in both SNK-6 and YTS cells (P＜0.01), but CCL22 mRNA expression increase in both cells (P＜0.01). MiR-30b mimics decreased the cell activity (P＜0.05), down-regulated the cisplatin-resistance (P＜0.05), and increased cell apoptosis and caspase-3 activity (P＜0.05). The effects of miR-30b inhibitor were contrary to the mimics. Up-regulation of miR-30b expression significantly decreased the luciferase activity in CCL22 3'-UTR-transfected NK cells, but not in Mut-CCL22 3'UTR group, suggesting that CCL22 could act as a direct target of miR-30b. The expressions of CCL22 pathway proteins were down-regulated after SNK-6 cells transfected with miR-30b mimics (P＜0.05), while this effect was restored by overexpression of CCL22. Moreover, CCL22 overexpression also increased the cell activity and decreased caspase-3 activity when SNK-6 cells were transfected with miR-30b mimics. CONCLUSION: MiR-30b inhibits cisplatin-resistance of human NK/TCL SNK-6 and YTS cells by targeting CCL22.

Maltol Mitigates Thioacetamide-induced Liver Fibrosis through TGF-ß1-mediated Activation of PI3K/Akt Signaling Pathway.

Our previous study has confirmed that maltol can attenuate alcohol-induced acute hepatic damage and prevent oxidative stress in mice. Therefore, maltol might have the capacity to improve thioacetamide (TAA)-induced liver fibrosis. The purpose of this work was to explore the antifibrotic efficacy and underlying mechanisms of maltol for TAA-treated mice. Progressive liver fibrosis was established with a dose-escalating protocol in which the mice received TAA intraperitoneal three times a week for a total duration of 9 weeks. The injection doses of TAA were 50 mg/kg for the first week, 100 mg/kg for the second and third weeks, and 150 mg/kg for the rest of the injections. Maltol with doses of 50 and 100 mg/kg was given by gavage after 4 weeks of intraperitoneal injection of TAA, respectively, once daily for 5 weeks. Results indicated that TAA intraperitoneal injection significantly increased serum activities of alanine aminotransferase (ALT) (52.93 ± 13.21 U/L vs 10.22 ± 3.36 U/L) and aspartate aminotransferase (AST) (67.58 ± 25.84 U/L vs 39.34 ± 3.89 U/L); these elevations were significantly diminished by pretreatment with maltol. Additionally, maltol ameliorated TAA-induced oxidative stress with attenuation in MDA ( p < 0.05 or p < 0.01) content; evident elevation in the GSH levels, GSH/GSSG ratio ( p < 0.05 or p < 0.01), and superoxide dismutase (SOD) ( p < 0.01); and restored liver histology accompanied by a decrease of α-smooth muscle actin (α-SMA) expression. Furthermore, maltol significantly suppressed the transforming growth factor-ß1 (TGF-ß1) expression and the PI3K/Akt pathway. This study suggested that maltol alleviated experimental liver fibrosis by suppressing the activation of HSCs and inducing apoptosis of activated HSCs through TGF-ß1-mediated PI3K/Akt signaling pathway. These findings further clearly suggested that maltol is a potent therapeutic candidate for the alleviation of liver fibrosis.

Healthy aging: A bibliometric analysis of the literature.

Due to dramatic growth of the aging population worldwide, there has been an urgent call for a public health strategy to manage healthy aging, with the ultimate goal being advancement of aging research. Considerable progress has been made in uncovering the mystery of aging process using multidisciplinary methods. There is a growing consensus in the field that aging traits which were originally thought to be disparate are likely to be interconnected. Thus, emerging research is needed to incorporate current findings of aging by building multiscale network models. This study reported the network of healthy aging research using bibliometric approaches. Based on the results, aging of the brain and muscle is a primary research focus which is a critical part of the multiscale network regulating the aging process. Among aging-associated diseases, Alzheimer's disease and frailty are among the main research focuses, and emerging work has focused on developing diagnostic tools for these diseases. For research on anti-aging interventions, calorie restriction, physical activity, and anti-aging pharmacology are the main interventions, of which the underlying mechanisms have been comprehensively studied in animal models.

Kidney Protection Effect of Ginsenoside Re and Its Underlying Mechanisms on Cisplatin-Induced Kidney Injury.

BACKGROUND/AIMS: Cisplatin (CDDP) was the first platinum-containing anti-cancer drug. However, CDDP causes nephrotoxicity as a side effect, which limits its clinic application. The aim of this study was to investigate the renoprotective effect of ginsenoside Re (G-Re) in a murine model of CDDP-induced acute kidney injury. METHODS: Male ICR mice were divided into 4 groups. G-Re was administered to the mice by oral gavage once a day at a dose of 25 mg/kg for 10 days. On the 7th day, a single injection of CDDP (25 mg/kg) was given at 1 h after G-Re treatment. RESULTS: CDDP administration resulted in renal dysfunction, as evidenced by an increase in the serum levels of creatinine and urea nitrogen. Oxidative stress in the CDDP group was reflected by an increase of malondialdehyde and a depletion of reduced glutathione and catalase in renal tissue. These findings were supported by increased 4-hydroxynonenal expression, which was significantly reduced by G-Re. Simultaneously, the overexpression of cytochrome P450 E1 was inhibited. G-Re inhibited the inflammatory response by the reduction of the protein expression of cyclooxygenase-2 and inducible nitric oxide synthase. Furthermore, CDDP increased the expression of Bax and decreased Bcl-2 expression in renal tissue. Hematoxylin and eosin, Hoechst 33258, and TUNEL staining also confirmed the presence of acute tubular necrosis and apoptosis. G-Re significantly decreased the levels of indicators of renal dysfunction, inflammatory cytokines, apoptosis, and malondialdehyde in the kidney and also significantly attenuated the histopathological changes associated with acute renal failure. CONCLUSIONS: Collectively, the results of this study suggest that the nephroprotective potential of G-Re may, in part, be related to its anti-oxidant, anti-inflammatory, and anti-apoptotic effects.

microRNA-485-5p Functions as a Tumor Suppressor in Colorectal Cancer Cells by Targeting CD147.

Colorectal cancer(CRC) is a prevalent malignancy in the world. There is growing evidence that microRNAs (miRNAs) as crucial modulator are in connection with many tumor-related diseases including CRC. Though miR-485-5p has been reported as an anti-oncogene in certain cancers, it remains unclear in CRC. In this research, we found that miR-485-5p was at lower level expression in CRC tissues and cell lines compared to the paired paracancerous tissues and the normal colon epithelial cell line FHC, correspondingly. Furthermore, Experimental up-regulation miR-485-5p in DLD-1 and SW480 cells with mimic could inhibit the ability of proliferation, migration, invasion of CRC cell lines and facilitate cells apoptosis. Also, we confirmed that CD147 existed typically negative regulation by miR-485-5p through binding a conserved sequence specifically within the CD147 3'-untranslated region (3'UTR) and reintroduction of CD147 could rescue the phenotypic changes caused by miR-485-5p. The findings provide evidence to demonstrate the role of miR-485-5p/CD147 interaction in CRC and indicate that miR-485-5p might be exploited therapeutically in CRC.

[Protective effect of Polygonum orientale flower extract on H2O2-induced oxidative damage of HUVEC cells].

To investigate the protective effects and mechanism of Polygonum orientale flower extract on H2O2-induced oxidative damage of human umbilical vein endothelial cells (HUVEC), H2O2 was used to induce the oxidativestress damage on HUVEC cells and efforts were made to screen the low, medium and high drug concentrations of P.orientale flower extract. Cell viability was detected by the MTS assay. The content of lactate dehydrogenase (LDH) and malondialdehyde (MDA), and the activities of superoxidedimutase (SOD) and catalase (CAT) were detected by biochemical kits. The mRNA and protein levels of Bax, Bcl-2 were detected respectively by quantitative real time polymerase chain reaction (qRT-PCR) and Western blot. The protein level of cleaved caspase-3 was detected by Western blot. According to the results, the viability of HUVEC cells was reduced to around 55% after being treated with 120 µmol·L⁻¹ H2O2 for 0.5 h. Treatment of H2O2 also could increase LDH leakage rate and MDA content and attenuate the activities of SOD and CAT, up-regulate the expression level of Bax and cleaved caspase-3, and down-regulate the expression level of Bcl-2. As compared with H2O2 model group, P.orientale flower extract of 50-200 mg·L⁻¹ could increase the viability of HUVEC cells, reduce LDH release and MDA content, enhance the activities of SOD and CAT, down-regulate pro-apoptotic protein cleaved caspase-3 and Bax, and up-regulate apoptosis inhibitory protein Bcl-2. In summary, P.orientale flower extract showed a protective effect on H2O2-induced HUVEC cells injury, which may result from enhancing the cell capability of clearing the oxygen free radial, decreasing the production of lipid peroxidation and inhibiting apoptosis.

High quality and high performance adsorption of Congo red using as-grown MWCNTs synthesized over a Co-MOF as a catalyst precursor via the CVD method.

A Co(ii) metal-organic framework (MOF) based on the pyridyl-amide-carboxylate-3-(2-pyridinecarboxylic acid)amido pyridine (HPCAP) ligand, namely [Co(PCAP)2]·2H2O (1), has been hydrothermally synthesized and structurally characterized, which was firstly used as a combined catalyst precursor to synthesize multi-walled carbon nanotubes (MWCNTs). The decomposition of ethylene in the presence of the Co-MOF by the chemical vapor deposition (CVD) method at 800 °C led to successful production of high quality as-grown MWCNT products. Interestingly, the as-grown MWCNTs exhibit high performance in the selective adsorption of Congo red (CR) with an adsorption capacity of 1639 mg g-1.

The Predictive and Prognostic Role of Stromal Tumor-infiltrating Lymphocytes in HER2-positive Breast Cancer with Trastuzumab-based Treatment: a Meta-analysis and Systematic Review.

Background Tumor-infiltrating lymphocytes (TILs) are white blood cells that have left the bloodstream and migrated into a tumor, involving in the prognosis of breast cancer (BC) patients. Published studies reported the value of TILs in patients with HER2-positive receiving trastuzumab-based treatment. However, the results obtained remain controversial. Here, we conducted this study to explore the predictive and prognostic role of TILs for HER2-positive BC patients receiving trastuzumab therapies. Method To identify the related published studies, a comprehensive literature search dating up to July 2017 was performed in the databases of PubMed, PMC, Web of Science and China National Knowledge Infrastructure (CNKI) according to predefined selection criteria. The pathologic complete response (pCR) and survival outcome of patients were measured by odds ratio (OR) and hazard ratio (HR) with corresponding 95% confidence interval (95% CI), respectively. The association between TILs and trastuzumab benefit was analyzed by using STATA version 11.0. Result Eleven eligible studies comprising 3228 patients were identified in the present study. The pooled results showed that high level of TILs was associated with a significantly improved pCR rate (OR = 1.32; 95% CI = 1.10-1.60) and longer survival (HR = 0.97; 95% CI = 0.96-0.99), particularly in the subgroups of retrospective study design and 10% INC cut-off value. Moreover, stratified analysis revealed that elevated TILs was a predictor of higher pCR rate in the Asian population and improved survival in the subgroups of Caucasian population and multivariate analysis. Conclusion This meta-analysis indicated that the level of stromal TILs was an independent predictive and prognostic marker for better outcome in HER2-positive BC patients receiving trastuzumab-based treatment. High level of TILs was significantly associated with trastuzumab benefit.

Association between SNPs in Long Non-coding RNAs and the Risk of Female Breast Cancer in a Chinese Population.

Long non-coding RNAs (LncRNAs) have been reported to be involved in tumorigenesis and tumor progression. Single nucleotide polymorphisms (SNPs) in the lncRNAs also play a vital role in carcinogenesis. The aim of this study was to assess the relationships between the four selected tagSNPs (rs944289, rs3787016, rs1456315, rs7463708) in the lncRNAs and the risk of female breast cancer in a Chinese population. A case-control study was carried out involving in a total of 439 breast cancer patients and 439 age-matched healthy controls. The genotyping was performed with Sequenom MassARRAY and the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) in tumor tissues was measured by the immunohistochemistry (IHC) assay. We found that rs3787016 TT genotype (adjusted odds ratio (OR) = 1.62, 95% confidence interval (CI) = 1.09-2.41, P = 0.018) was associated with an increased risk of female breast cancer, especially among the patients with premenopausal status (adjusted OR = 2.55, 95% CI = 1.30-4.97, P = 0.006). Moreover, a statistically significant increased risk of the rs3787016 TT genotype was observed among the patients with advanced tumor stage (Ⅲ and Ⅳ), poor histological grade (G3-G4), positive lymph node involvement, positive expression of ER and PR and negative expression of HER-2; rs7463708 GT and GT/GG genotype were associated with decreased risk of breast cancer in the subgroup of patients with postmenopausal status (GT versus (vs.) TT: adjusted OR = 0.67, 95% CI = 0.46-0.99, P = 0.043; GT/GG vs. TT: adjusted OR = 0.68, 95% CI = 0.47-0.98, P = 0.041) and tumor late-stage (GT vs. TT: adjusted OR = 0.65, 95% CI = 0.43-0.97, P = 0.037; GT/GG vs. TT: adjusted OR = 0.65, 95% CI = 0.44-0.96, P = 0.029). In short, rs3787016 TT genotype was associated with increased breast cancer risk and clinicopathologic features of the tumor, especially among premenopausal women.

Reproducibility of Perfusion Parameters of Optic Disc and Macula in Rhesus Monkeys by Optical Coherence Tomography Angiography.

BACKGROUND: Optical coherence tomography (OCT) angiography is a novel technique by which we can detect the local perfusion of fundus directly. The aim of this study was to evaluate the reproducibility of optic disc and macular flow perfusion parameters in rhesus monkeys using OCT angiography. METHODS: Eighteen healthy monkeys (18 eyes) were subjected to optic disc and macula flow index measurements via a high-speed and high-resolution spectral-domain OCT XR Avanti with a split-spectrum amplitude de-correlation angiography algorithm. Right eye was imaged 3 times during the first examination and once during each of the two following examinations. The intra-visit and inter-visit intraclass correlation coefficients (ICCs) were both determined. RESULTS: The average flow indices of the four optic disc area layers were 0.171 ± 0.009 (optic nerve head), 0.015 ± 0.004 (vitreous), 0.052 ± 0.009 (radial peripapillary capillary), and 0.167 ± 0.011 (choroid). Average flow indices of the four macula area layers were 0.044 ± 0.011 (superficial retina), 0.036 ± 0.011 (deep retina), 0.016 ± 0.009 (outer retina), and 0.155 ± 0.013 (choroid). Intra-visit (ICC value: 0.821-0.954) and inter-visit (ICC value: 0.844-0.899) repeatability were both high. CONCLUSIONS: The study is about the reproducibility of optic disc and macular perfusion parameters as measured by OCT angiography in healthy rhesus monkeys. Flow index measurement reproducibility is high for both the optic disc and macula of normal monkey eyes. OCT angiography might be a useful technique to assess changes when examining monkeys with experimental ocular diseases.
