To examine whether vascular endothelial growth factor (VEGF) as one of the most important intraocular cytokines for angiogenesis and increased permeability is associated with Coats' disease.The clinical interventional study included 28 patients disease seven control congenital cataract. During surgery, we obtained aqueous humour samples in which VEGF concentration was measured by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). graded into four stages.The mean level...
BACKGROUND Hepatic artery infusion chemotherapy (HAIC) is a widely used local therapeutic approach for intermediate to advanced-stage hepatocellular carcinoma (HCC), exhibiting considerable efficacy. However, the prevalence of postoperative pain highlights importance management. Owing limitations inherent in existing management strategies, this study investigates and assesses analgesic effectiveness multimodal treatment protocol mitigating after HAIC procedures. AIM To provide patients with...
To find the potential relation between changes in retinal large vessels and terminal using colour Doppler flow imaging (CDFI) optical coherence tomography angiography (OCTA) to compare respective advantages of CDFI OCTA evaluating vascular retinitis pigmentosa (RP) patients.A prospective series case study was conducted enrol RP patients age-matched controls, who were, respectively, imaged by OCTA. Repeatability reproducibility both were performed among healthy volunteers. The central artery...
Purpose To examine whether an abnormally thin retinal nerve fiber layer (RNFL) is associated with cerebrovascular insufficiency. Design Community-based study. Methods The Asymptomatic Polyvascular Abnormalities in Community Study included Chinese aged 40+ years and without histories of incidents or coronary heart disease. Using transcranial Doppler carotid duplex ultrasound examination, we assessed presence degree intracranial arterial stenosis (ICAS) extracranial (ECAS) measured the RNFL...
In the present study, axial length (AL), corneal curvature, anterior chamber depth (ACD) and white‑to‑white (WTW) distance were assessed using Pentacam AXL (Oculus Optikgeraete GmbH), a novel Scheimpflug‑based optical biometer with standard partial coherence interferometry (PCI). The PCI (IOLMaster 500; Carl Zeiss AG) compared in terms of their intraocular lens (IOL) power calculations. medical records patients (eyes, n=190) who underwent cataract surgery retrospectively reviewed. Biometry...
Objective: To compare biometry with new biometers of Pentacam AXL and IOLMaster 700 the widely used biometer 500 in cataract patients. Methods: Cross-sectional study. A total 223 eyes 147 patients from Beijing Tongren Eye Center, Hospital, Capital Medical University during 4-8 December 2017 were recruited. There 67 males 80 females an age (64±11) years.The axial length (AL), mean keratometry (Km), anterior chamber depth (ACD) white-to-white corneal diameter (WTW) each device recorded. The...
In-line X-ray phase-contrast computed tomography (IL-PCCT) can reveal fine inner structures for low- Z materials ( e.g. biological soft tissues), and shows high potential to become clinically applicable. Typically, IL-PCCT utilizes filtered back-projection (FBP) as the standard reconstruction algorithm. However, FBP algorithm requires a large amount of projection data, subsequently radiation dose is needed reconstruct high-quality image, which hampers its clinical application in IL-PCCT. In...
Abstract Purpose To study the retrobulbar haemodynamics in patients with Coats’ disease. Methods The clinical included 43 Using colour Doppler imaging, we measured blood flow velocity ophthalmic artery ( OA ), central retinal CRA ) and posterior ciliary arteries PCA recorded peak systolic PSV end diastolic EDV time averaged maximum TAMX pulsatility index PI resistance indexes RI ). unaffected contralateral eyes served as control group. disease was graded into four stages. Results Compared to...
In-line X-ray phase-contrast computed tomography (IL-PCCT) is a valuable tool for revealing the internal detailed structures in weakly absorbing objects ( e.g. biological soft tissues), and has great potential to become clinically applicable. However, long scanning time IL-PCCT will result high radiation dose samples, thus impede wider use of clinical biomedical imaging. To alleviate this problem, new iterative CT reconstruction algorithm presented that aims decrease by reducing projection...
Background More recently, the swept-source OCT biometer-IOLMaster 700 has provided direct total corneal power measurement, named keratometry. This study aims to evaluate whether standard keratometry (SK) and (TK) with IOLMaster can accurately reflect changes induced by myopic refractive surgery. Methods In this study, biometric data measured biometer—IOLMaster before 3 months after surgery were recorded. The of biological parameters, including SK, posterior (PK), TK, difference between SK TK...

Abstract Gliomas are rich in blood vessels, and the generation of tumor‐associated vessels plays an important role glioma growth transfer. Histology can directly depict microvascular architecture tumor, but it just provides two‐dimensional (2D) images obtained by destroying three‐dimensional (3D) tissue specimens. There is a lack high‐resolution 3D imaging methods for observing microvasculature throughout entire X‐ray phase‐contrast computed tomography (PCCT) which emerging method has...
Objective: To compare the accuracy of different corneal curvature parameters in assessing refractive status and tracking power changes after small incision lenticule extraction (SMILE). Methods: This prospective cross-sectional study tracked recorded total measured by instruments before three months SMILE for myopia. These parameters, including keratometry (TK) from IOLMaster 700, (TCRP) Pentacam AXL, real (RK) CASIA 2, corrected calculated using Haigis, Shammas, Maloney methods, were...
Objective: To investigate the application value of Pentacam combined with Corvis ST in evaluation changes corneal biomechanics after femtosecond laser small incision lenticule extraction (SMILE) Chinese myopia an irregular cornea. Methods: The clinical records for 104 eyes 57 patients who received SMILE Refractive Center Beijing Tongren Hospital during January 2018 and May were collected. According to keratoconus severity index (KSI), they divided into two groups: regular group (KSI<15%)...

Abstract Clear and complete microstructural imaging of the root canal isthmus is an important part pathological investigations in research clinical practice. X‐ray micro‐computed tomography (μCT) a widely used non‐destructive technique, which allows for distortion‐free three‐dimensional (3D) visualisation. While absorption μCT typically has poor contrast resolution observing isthmus, especially weak‐absorbing tissues, propagation‐based phase‐contrast (PBI) powerful method, its combination...
