Objective: The study aims to assess two refractive instrument-based methods of vision screening (SureSight and PlusoptiX) to detect refractive amblyopia risk factors (ARFs) and significant refractive errors in Chinese preschool children and to develop referral criteria according to the 2021 AAPOS guidelines.

Methods: Eye examinations were conducted in children aged 61 to 72 months ( = 1,173) using a PlusoptiX photoscreener, SureSight autorefractor, and cycloplegic retinoscopy (CR). The Vision Screening Committee of AAPOS's preschool vision screening guidelines from 2021 were adopted for comparison.

Objective: To explore the association between sleep disorders and subfoveal choroidal thickness (SFCT) in preschool children.

Methods: In this population-based cross-sectional study, children aged 60-72 months were measured for SFCT using spectral-domain optical coherence tomography (SD-OCT) and for sleep disorders using the Chinese version of Children's Sleep Habits Questionnaire (CSHQ). Multiple linear regression analyses were performed to assess the association between sleep disorders and SFCT.

Backgrounds: Aniso-astigmatism may hinder normal visual development in preschool children. Knowing its prevalence, biometric parameters and risk factors is fundamental to children eye care. The purpose of this study was to determine the biometric components of aniso-astigmatism and associated maternal risk factors in Chinese preschool children.

Aims: To evaluate the prevalence, incidence and their related risk factors of strabismus among preschool children in China.

Methods: Children born between September 2011 and August 2012 in Yuhuatai District of Nanjing were invited to participate in the Nanjing Eye Study for a comprehensive eye examination annually since 2015. The data presented in this paper were obtained from 2015 to 2017, when these children grew from the age of 3 to 5 years.

Aims: To determine prevalence, causes, and risk factors of reduced uncorrected visual acuity (UCVA), reduced presenting visual acuity (PVA), and persistent reduced visual acuity (VA) among Chinese preschool children.

Methods: The longitudinal, population-based Nanjing Eye Study (NES) was carried out. Children underwent baseline comprehensive ocular examinations in 2016 (at 48-60 months old) and the follow-up ocular examinations in 2017.

Purpose: To determine the risk factors for total astigmatism (TA), anterior corneal astigmatism (ACA), and internal compensation in Chinese preschool children.

Methods: In the population-based Nanjing Eye Study, children were measured for noncycloplegic refractive error and for biometric parameters. Data from questionnaires and measures from right eyes were analyzed for determining risk factors for TA, ACA, and internal compensation from multivariate logistic regression models.

Purpose: To evaluate the influence of maternal gestational hypertension (GH) on retinal thickness of 5-6-year-old children, including macular thickness, ganglion cell-inner plexiform layer (GC-IPL) thickness and peripapillary retinal nerve fibre layer (RNFL) thickness.

Methods: As part of Nanjing Eye Study, comprehensive ocular examinations were conducted in children aged 61-72 months, including noncycloplegic refraction, ocular biometric parameters and retinal parameters. Retinal thickness was measured by Spectral Domain-Optical Coherence Tomography.

: To assess the distribution of stereoacuity and related factors in healthy preschool children aged 48-60 months in eastern China. : This cross-sectional study was part of the Nanjing Eye Study, a longitudinal population-based cohort study. In 2016, preschool children without any neurological problems or ophthalmological abnormalities completed comprehensive eye examinations, including visual acuity, ocular alignment and movements, cycloplegic refraction, axial length, interpupillary distance, Titmus stereotest, anterior segment, and fundus examination.
