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.

目的：研究佛山市禅城区五年级、六年级近视儿童的心理健康及其影响因素，为解决其因近视产生的心理问题及近视防治工作提供依据。方法：选择佛山市禅城区3所小学，在其五年级、六年级选择2个班作为调查对象开展近视筛查、并使用儿童社交焦虑量表、孤独量表以及儿童自尊量表进行心理健康测量。结果：佛山市禅城区近视患病率52.0%，女性(57.5%)较男性(47.4%)有较高患病率，六年级患病率(57.6%)高于五年级(46.3%)。近视儿童均比正常视力儿童存在明显的社交焦虑、孤独感以及低自尊度(得分分别为5.53±4.04 vs 4.66±3.59，30.15±11.72 vs 27.29±10.40，97.97±12.73 vs 100.87±12.21)，差异均具有统计学意义(均P<0.05)。进一步分析显示，初发近视社会焦虑、孤独以及自尊方面比中度近视明显。性别、年龄等社会因素对于近视儿童心理健康影响不明显。根据矫正的不同方式分类，近视儿童中，戴角膜塑形镜者社交焦虑感较低(F=4.21，P=0.01)，戴框架眼镜者则较容易产生较低的自尊度(F=5.67，P=0.02)。结论：小学生近视问题是全社会普遍关心的问题，近视与其心理健康关系密切，这需要全社会密切配合，采取综合措施，且近视矫正方式的选择影响近视儿童的心理。

Objective: By studying the mental health and its influencing factors of myopia children in grade 5 and grade 6 in Chancheng District, Foshan City, this paper provided the basis for solving the psychological problems caused by myopia and the prevention and treatment of myopia. Methods: Three primary schools in Chancheng District,Foshan City were chosen. Two classes in grade 5 and grade 6 were selected to carry out myopia screening followed  by evaluation of their mental health with children’s social anxiety scale, loneliness scale and children’s self-esteem scale. Results: The prevalence of myopia was 52.0% in Chancheng District, Foshan City. Females (57.5%) had a higher prevalence than males (47.4%). The prevalence in grade 6 (57.6%) was higher than that in grade 5 (46.3%).Children with myopia had obvious social anxiety, loneliness, and low self-esteem (scores of 5.53±4.04 vs 4.66±3.59,30.15±11.72 vs 27.29±10.40, 97.97±12.73 vs 100.87±12.21, respectively) than those with normal vision, whose difference was statistically significant (all P<0.05). Further analysis showed that social anxiety, loneliness, and self-esteem in children with primary myopia were more obvious than those with moderate myopia. Social factors such as gender and age had little effect on the mental health of myopic children. According to different correction methods, among myopic children, those who wore orthokeratology lenses had lower social anxiety (F=4.21, P=0.01), and those who wore spectacles were more likely to have lower self-esteem (F=5.67, P=0.02).Conclusion: The problem of myopia in primary school students, which is closely related to mental health, is of

general concern to the whole society. This requires the whole society to cooperate closely and take comprehensive measures. The choice of myopia correction methods affects the psychology of myopic children.
