摘　　要：目的分析学龄前视力低常儿童散光眼分布特征,全面探究其散光类型、分布以及矫正情况,旨意为相关研究人员提供理论依据。方法选择2016年1月至2016年12月温州医科大学附属眼视光医院收治的912例学龄前视力低常者(1 730眼)为研究对象,实施散瞳验光,分析统计学结果。结果单眼散光者94例,占10.3%。双眼散光者818例,占89.7%。对称性散光者710例,占86.6%,不对称散光者108例,占13.2%。顺规散光1 646眼,占95.1%,逆规散光64眼,占3.7%,斜轴散光20眼,占1.2%。矫正视力在0.9以上者共计412眼,占23.8%。0.8以下共计1 318眼,占76.2%。在该部分群体中,远视性散光共计1 042眼,近视散光共计30眼。混合散光共计246眼。复性远视散光1188眼,占68.7%,复性近视散光38眼,占2.2%。单纯近视散光6眼,占0.4%,单纯远视散光204眼,占11.79%。混合散光294眼,占17.0%。0.50 D^1.00 D占31.7%,1.25 D^2.00 D占46.4%,2.25 D^3.00 D占15.6%,3.25 D^4.00 D占4.9%,4.25 D^5.00 D占1.3%。5.25 D以上占0.2%。结论在学龄前视力低常群体中,双眼散光为常见疾病类型,其中以复性远视散光为主。散光程度一般在3.00 D以下,轴向分布以顺规散光为主。重度散光为引发弱视的主要因素,因此对于视力低常学龄前儿童,应当做好早期视力筛查,以便尽早矫正散光,恢复正常视力。Objective To analyze preschool low vision children often astigmatism distribution characteristics, type, distribution, and fully explore the astigmatism correction, will provide theoretical basis for related researchers. Methods Between January 2016 and December 2016, our hospital 912 cases of preschool vision low often （1 730 eyes） as the research object, the implementation of specialized perspective, analysis of statistical results. Results 94 cases of monocular astigmatism, accounting for 10. 3%. Eyes astigmatism, 818 cases, accounting for 89.7%. Symmetry astigmatism, 710 cases, accounting for 86. 6% , 108 cases of asymmetric astigmatism, accounting for 13.2%. Shun gauge astigmatism, 1 646 eyes （95. 1% ） , and the inverse rule astigmatism 64 eyes, 3. 1% oblique astigmatism 20 eyes, accounting for 1.2%. Vision correction in 0. 9 more than a total of 412 eyes, accounting for 23. 8%. , 0. 8 following a total of 1318 eyes （76. 2% ）. In this part of the group, hyperopia astigmatism for a total of 1 042 eyes, a total of 30 eye myopic astigmatism. A total of 246 eyes mixed astigmatism. Compound hyperopic astigmatism, 1 188 eyes （68. 7% ） , and compound myopic astigmatism 38 eyes, accounting for 2. 2% , simple myopic astigmatism 6 eyes （0.4 % ） ,simple hyperopia astigmatism 204 eyes, accounted for 11. 79% , mixed astigmatism 294 eyes, accounting for 17. 0 % . 0. 50 D -1. 00 D accounted for 31. 7% , 1. 25 D -2. 00 D accounted for 46. 4% , 2. 25 D -3. 00 D accounted for 15. 6% , 3. 25 D -4. 00 D accounted for 4. 9% , 4. 25 D - 5. 00 D accounted for 1. 3% . 5. 25 D above 0. 2% . Conclusion In preschool in groups with low vision is always eyes astigmatism for common disease types, which is given priority to with irreversible hyperopic astigmatism. Astigmatism degree generally under 3. 00 D, axial distribution is given priority to with suitable gauge astigmatism. Severe astigmatism for the main factors that cause amblyopia, so for
