目的：评估分析新疆地区14个地州6~18岁学龄儿童青少年屈光参差的患病率、空间分布特征和影响因素，为制定区域性眼健康干预策略提供科学依据。方法：采用横断面研究设计，纳入新疆地区14个地州的小学、初中及高中学生共64 277名，收集其人口学特征、屈光状态及地域分布数据。通过等效球镜度（spherical equivalent，SE）评估屈光状态，近视为SE ≤ -0.50 D，屈光参差为眼间SE差异≥1.0 D，采用Moran's I分析屈光参差患病率的空间分布，采用单因素及多因素回归分析探讨屈光参差的危险因素。结果：屈光参差的总体患病率为17.9%（95% CI：17.6%～18.2%），女性屈光参差患病率（18.8%）高于男性（16.9%），汉族（23.9%）高于维吾尔族（11.7%）和其他民族（18.4%）（P<0.001）。屈光参差患病率呈空间聚集分布(Moran's I = 0.450，P = 0.043，Z = 2.026)，并且存在地域差异，昌吉最高（24.1%），克孜勒苏柯尔克孜自治州最低（7.9%），城市（19.0%）高于农村（15.6%），北疆（19.9%）高于南疆（13.5%）（P<0.001）。屈光参差的患病率与年龄呈正相关，6岁为9.8%，18岁达22.4%。多因素回归分析显示，女性、北疆地区、近视和较高年龄是屈光参差的独立危险因素（P<0.05）。结论：新疆地区学龄儿童青少年屈光参差患病率较高，在空间上呈聚集分布，且存在显著的人口学及地域差异，女性、北疆地区、近视和较高年龄是屈光参差的独立危险因素，建议加强对高危人群的视力筛查及早期干预。  

Objective: To evaluate and analyze the prevalence, spatial distribution characteristics, and influencing factors of anisometropia among school-aged children and adolescents aged 6-18 across 14 prefectures in Xinjiang, thereby providing a scientific foundation for formulation of regional eye health intervention strategies. Methods: A cross-sectional study design was employed, including 64,277 students from primary, middle, and high schools in 14 prefectures of Xinjiang. Data on demographic characteristics, refractive status, and geographical distribution were collected. Refractive status was assessed using spherical equivalent (SE). Myopia was defined as SE ≤ -0.50 D, and anisometropia was defined as an interocular SE difference ≥ 1.0 D. Moran's I analysis was used to evaluate the spatial distribution of anisometropia prevalence. Additionally, univariate and multivariate regression analyses were conducted to identify risk factors for anisometropia. Results: The overall prevalence of anisometropia was 17.9% (95% CI: 17.6%-18.2%). The prevalence was higher among females (18.8%) compared to males (16.9%), and higher among Han Chinese (23.9%) than among Uyghurs (11.7%) and other ethnic groups (18.4%) (P<0.001). The prevalence of anisometropia showed a spatially clustered distribution (Moran's I = 0.450, P= 0.043, Z-score = 2.026) , with notable regional variations. Changji had the highest prevalence (24.1%), while Kizilsu Kirghiz Autonomous Prefecture had the lowest (7.9%). Urban areas (19.0%) had a higher prevalence than rural areas (15.6%), and northern Xinjiang (19.9%) had a higher prevalence than southern Xinjiang (13.5%) (P<0.001). The prevalence of anisometropia was positively correlated with age, increasing from 9.8% at age 6 to 22.4% at age 18. Multivariate regression analysis showed that female gender, residing in northern Xinjiang, myopia, and older age were independent risk factors for anisometropia. Conclusions: The prevalence of anisometropia among school-aged children and adolescents in Xinjiang is relatively high, showing a spatially clustered distribution with significant demographic and regional disparities. Female gender, residing in northern Xinjiang, myopia, and older age are independent risk factors for anisometropia. It is recommended to enhance vision screening and implement early intervention for high-risk populations.

目的：了解新疆喀什地区英吉沙县7~16岁儿童青少年弱视患病情况及其相关因素，为制定科学有效的眼健康防控策略提供依据。方法：选取新疆喀什地区英吉沙县3 261名在校儿童青少年，对其进行裸眼视力、最佳矫正视力、屈光度、眼位和眼底情况等检查，并通过问卷调查收集其基本人口学信息、近视家族史、用眼情况和睡眠情况，采用Logistic回归分析7~16岁儿童青少年弱视患病的相关因素。结果：英吉沙县儿童青少年弱视的患病率为1.99%（95%·CI: 1.51~2.47）。弱视患病率在学生类型、性别、近视家族史、主观睡眠质量、每天写作业时间、每天睡眠时间等方面比较差异无统计学意义（P＞0.05），在斜视、近视、远视、屈光参差、每天使用电子产品时间等方面比较差异有统计学意义（P＜0.05）。多因素回归分析结果显示，斜视、远视、屈光参差及每天使用电子产品时间与弱视相关，对应的OR值相应为3.82（95%CI: 1.93~7.58，P＜0.001）、10.88（95%CI: 4.85~24.40，P＜0.001）、13.54（95%CI:6.84~26.78，P＜0.001）和0.25（95%CI: 0.12~0.54, P＜0.001），合并斜视、远视或屈光参差的儿童青少年患弱视的风险增加。每天使用电子产品时间＞60 min的儿童青少年患弱视风险较使用时间≤60 min降低。弱视类型以屈光不正性弱视和屈光参差性弱视为主。结论：在新疆喀什地区英吉沙县7~16岁儿童青少年人群中，屈光不正和屈光参差是弱视患病的主要原因。斜视、远视、屈光参差、每天使用电子产品时间是弱视的影响因素。

Objective: To conduct a comprehensive investigation into the prevalence of amblyopia and its influencing factors among children and adolescents aged 7-16 in Yingjisha County, Kashgar Prefecture, Xinjiang. The ojective is to furnish a solid basis for formulating scientific and effective eye health prevention and control strategies. Methods: A total of 3,261 school-aged children and adolescents in Yingjisha County, Kashgar Prefecture, Xinjiang, were selected for this study. The examinations included uncorrected visual acuity, best-corrected visual acuity, refractive error, ocular alignment, and fundus condition. A questionnaire was used to collect demographic information, family history of myopia, daily eye-use habits, and sleep status. The data were analyzed using SPSS statistical software, and logistic regression was employed to explore factors associated with amblyopia in children and adolescents aged 7-16. Results: The study revealed that the prevalence of amblyopia among children and adolescents in Yingjisha County was 1.99% （95% CI: 1.51-2.47）. There were no significant differences (P > 0.05) in the prevalence of amblyopia across student type, sex, family history of myopia, subjective sleep quality, daily homework duration, or daily sleep duration. However, significant differences (P < 0.05) were observed in cases involving strabismus, myopia, hyperopia, anisometropia, and daily screen time. Multivariate regression analysis indicated that strabismus (OR = 3.82, 95% CI: 1.93-7.58, P < 0.001), hyperopia (OR = 10.88, 95% CI: 4.85-24.40, P < 0.001), and anisometropia (OR = 13.54, 95% CI: 6.84–26.78, P < 0.001) were positively correlated with amblyopia. Conversely, children and adolescents who used electronic devices for >60 minutes per day had a lower risk of amblyopia (OR = 0.25, 95% CI: 0.12-0.54, P < 0.001) compared to those with ≤60 minutes or less of daily screen time. The most common type of amblyopia was mixed amblyopia （60.00%）, followed by anisometropic amblyopia （23.08%）, refractive amblyopia （12.31%）, and strabismic amblyopia （4.62%）. Among mixed amblyopia cases, the combination of refractive amblyopia and anisometropic amblyopia was the predominant pattern （64.10%）. Conclusions: Refractive errors and anisometropia are the main causes of amblyopia. Strabismus, myopia, hyperopia, anisometropia and the duration of electronic device use are identified as influencing factors for amblyopia.

目的：比较轻、中、重度近视患儿之间的视觉功能的差异，探索虚拟现实下的短期可塑训练对近视视觉功能的改善效果。方法：选择2022年6月—2022年9月就诊于苏州大学附属儿童医院的6~16岁儿童102例，按照屈光度分为正常对照组、轻度近视组和中重度近视组，进行眼科常规检查和视知觉功能检查，并进行视觉短期可塑训练。结果：近视患儿存在立体视功能缺损，近视程度与精细立体视功能损害呈正相关，各组之间比较差异具有统计学意义(P<0.05)，部分患儿存在中心凹抑制。训练后，轻度近视组的中距离精细立体视功能得到改善，比较差异具有统计学意义(P<0.05)。结论：近视患儿存在立体视功能异常和中心凹抑制，且立体视功能的损害随着近视程度的增加而加重。轻度近视患儿部分精细立体视功能经过虚拟现实短期可塑训练可得到改善，而中重度近视患儿精细立体视功能改善不明显。

Objective: To compare the difference of visual function among children with myopia in different diopter, and explore the effect of short-term plastic training of virtual reality on visual function improvement. Methods: The 102 children aged 6-16 years who admitted to Children's Hospital of SoochowUniversity from June 2022 to September 2022 were recruited and divided into control group, mild myopia group and middle and high myopia group according to diopter. Routine ophthalmologic examination and visual perception function examination were carried out, and short-term plastic training was implemented. After the training, visual perception function examination was completed again. Results: There were significant differences in stereoscopic function defect at different distances among myopic children, a negative correlation between myopia and stereoscopic function was found. while there were several cases have foveal suppression. After training, the fine stereopsis at medium distance of the mild myopia group was significantly improved with significance statistical difference. Conclusions: Myopia can lead to the abnormality of stereopsis and foveal suppression in children. The defect of binocular visual function increases with the increase of myopia. Short term plastic training of virtual reality can partially improve the fine stereoscopic function of mild myopia children whileshowsnosigni ficanceimprovementof the fine stereoscopic function in middle and high myopia group.
