Vessel Density and Structural Measurements in Primary Angle-Closure Suspect Glaucoma Using Optical Coherence Tomography Angiography.

Purpose: To measure the macular retinal vessel density (VD) and peripapillary retinal nerve fiber layer (RNFL) in primary angle-closure suspects (PACS) by Angio-OCT to be compared with normal subjects.

Methods: Primary angle-closure suspect patients and normal subjects were enrolled in this study. The demographic and clinical characteristics of all subjects, such as RNFL thickness, retinal vessel density, and ocular perfusion pressure, were compared.

Longitudinal Changes in Diffusion Tensor Imaging Following Mild Traumatic Brain Injury and Correlation With Outcome.

The chronic consequences of traumatic brain injury (TBI) may contribute to the increased risk for early cognitive decline and dementia, primarily due to diffusion axonal injury. Previous studies in mild TBI (mTBI) have been controversial in describing the white matter tract integrity changes occurring at acute and subacute post-injury. In this prospective longitudinal study, we aim to investigate the longitudinal changes of white matter (WM) using diffusion tensor imaging (DTI) and their correlations with neuropsychological tests.

Lower Posttraumatic α-Synuclein Level Associated With Altered Default Mode Network Connectivity Following Acute Mild Traumatic Brain Injury.

This study aimed to investigate the changes of α-synuclein in serum and its relationship with default mode network (DMN) connectivity after acute mild traumatic brain injury (mild TBI). Fifty-two patients with mild TBI at the acute phase and 47 matched healthy controls were enrolled in the study. All participants received resting-state functional magnetic resonance imaging (fMRI) and neuropsychological assessments.

Evaluation of choroidal thickness in amblyopia using optical coherence tomography.

Objective: To investigate the choroidal thickness in children with amblyopia through spectral-domain optical coherence tomography.

Methods: A total of 31 children with unilateral amblyopia and 31 right eyes of controls with normal vision were enrolled in the study. The choroidal thickness was measured directly below the fovea and at 12 other locations: 1, 2 and 3 mm superior, temporal, inferior, and nasal to the fovea.

Posterior pole asymmetry analysis and retinal nerve fibre layer thickness measurements in primary angle-closure suspect patients.

Purpose: To measure peripapillary retinal nerve fiber layer (RNFL) thickness and posterior pole retinal thickness in primary angle-closure suspects (PACS) by Spectral domain optical coherence tomography (SD-OCT) and to be compared with normal subjects.

Methods: Thirty five primary angle-closure suspect patients and thirty normal subjects were enrolled in this study. Peripapillary RNFL and posterior pole retinal thickness by posterior pole asymmetry analysis (PPAA) in SD-OCT were measured.

Sex differences in cerebral perfusion changes after mild traumatic brain injury: Longitudinal investigation and correlation with outcome.

Cerebral blood flow (CBF) is known to have marked developmental sex differences. We investigated whether gender differences exert modulatory effect on mild traumatic brain injury (mTBI) from both neuropsychological testing and brain CBF changes using a longitudinal design from acute stage to subacute 1 month post-injury. Our results supported that cognitive information processing speed (IPS), as one of core cognitive impairments following mTBI, were at least partially independent from other self-reported syndromes, such as post concussive symptom and posttraumatic stress disorder, and that it can be selectively impaired in specific male mTBI individuals.

Evaluation of peripapillary choroidal distribution in children by enhanced depth imaging optical coherence tomography.

Background: To evaluate the peripapillary choroidal thickness (PPCT) in Chinese children aged 6 to 12 years old and to analyze correlative factors.

Methods: PPCT was measured with enhanced depth imaging optical coherence tomography (EDI-OCT) in 154 children (76 myopes and 78 emmetropia) aged 6 to 12 years, with spherical equivalent refractive errors between + 0.50 and - 5.

[Moderate and severe persistent allergic rhinitis treated with acupoint application therapy of the different intensity: a randomized controlled trial].

Objective: To evaluate the clinical therapeutic effects and safety on moderate and severe persistent allergic rhinitis treated with acupoint application therapy of the different intensity during the dog days.

Methods: One hundred and sixty patients of moderate and severe persistent allergic rhinitis were randomized into a No.1 treatment group, a No.

Axial Length and Ocular Development of Premature Infants without ROP.

Purpose: To investigate the ocular parameters of premature infants without ROP at gestational age (GA) more than 28 weeks and their relationship with growth parameters.

Methods: 76 preterm infants without ROP and 65 term infants were involved to undergo portable slit lamp, RetCam3, ultrasonic A-scan biometry, and cycloplegic streak examination at their 40 weeks' postconceptional ages (PCA). Ocular parameters of infants' right eye and growth parameters were used for analysis.

Evaluation of myopia on retinal nerve fiber layer thickness measured by Spectralis optical coherence tomography.

The aim of the present study was to evaluate the retinal nerve fiber layer (RNFL) thickness of myopic subjects using Spectralis optical coherence tomography (OCT) and to determine variations with age and sex. A total of 271 Chinese participants with a spherical equivalent <+0.50 diopters were enrolled in the research.
