目的：探讨新疆和田县4-14岁维吾尔族学生远视储备现状与眼部生物学参数的关系，为近视预防提供科学依据。

方法：采用分层随机整群抽样法选取2023年9月1日至2023年10月31日和田县6所学校的学生3 264名3 264眼，进行裸眼远视力、睫状肌麻痹后电脑验光及眼部生物学测量。通过多元线性回归分析非近视学生等效球镜度(SE)与眼部生物学参数的相关性。

结果：最终纳入1 998名1 998眼非近视学生，其中1 354人远视储备不足，检出率为67.77%。远视储备不足的检出率随着年龄增大而降低，从4岁的94.12%降至14岁的18.13%(P<0.001)。多元线性回归分析显示，远视储备充足组中，年龄、性别、裸眼远视力、眼轴(AL)和平均角膜曲率(K)共同解释了66.5%的SE变异； 而远视储备不足组中，这些因素仅解释了28.0%的SE变异。

结论：新疆4-14岁维吾尔族非近视学生中，远视储备不足的检出率为67.77%。在远视储备不足的群体中，年龄、性别、AL和平均K值仅能解释少部分的SE变异，表明该人群屈光状态可能受到更多复杂因素的影响。

METHODS: From September 1 to October 31, 2023, a stratified random cluster sampling method was used to select 3 264 students(3 264 eyes)from 6 schools in Hotan County. Participants underwent uncorrected distance visual acuity testing, cycloplegic refraction, and ocular biometric measurements. The correlation between spherical equivalent(SE)and ocular biometric parameters was analyzed by multiple linear regression.

RESULTS: A total of 1 998 non-myopic students(1 998 eyes)were included in the study, with 1 354 students(67.77%)showing insufficient hyperopia reserve. The detection rate of insufficient hyperopia reserve decreased with age, from 94.12% at age 4 to 18.13% at age 14(P<0.001). Multiple linear regression analysis showed that in the group with sufficient hyperopia reserve, age, gender, uncorrected distance visual acuity, axial length(AL), and keratometry(K)explained 66.5% of the variance in SE; while in the group with insufficient hyperopia reserve, these factors explained only 28.0% of the SE variance.

CONCLUSION: In non-myopic Uyghur students aged 4-14 in Hotan County, Xinjiang, the detection rate of insufficient hyperopia reserve was 67.77%. In the group with insufficient hyperopia reserve, age, gender, AL, and K explained only a small portion of the SE variance, suggesting that the refractive status of this population may be influenced by more complex factors.
