目的探讨学龄前儿童Suresight视力筛查仪检查柱镜呈±9.99D的屈光意义。方法 Suresight视力筛查仪检查柱镜呈±9.99D的学龄前儿童,采用1%阿托品散瞳后检影验光,分析检影验光结果。结果 Suresight视力筛查仪检查柱镜呈±9.99D32例36眼,屈光状态分布以混合散光最多,27眼,占75.00%;远视性屈光9眼,占25.00%,近视性屈光0眼;散光绝对值分布,柱镜绝对值为3.50D-4.75D,平均为4.00D。结论学龄前儿童Sure-sight视力筛查仪检查柱镜呈±9.99D都是大散光眼,绝对值为3.50D-4.75D,平均为4.00D,以混合散光为主。
Objective To investigate the significance of refraction of presbyopic Suresight preschoolers to ± 9.99D in cylinder. Methods Suresight vision screening instrument to check the cylinder was ± 9.99D pre-school children, using 1% atropine mydriasis retinoscopy optometry, analysis retinoscopy results. Results Suresight vision screening instrument showed that the cylinder was ± 9.99D32 and 36 eyes. The refractive state distribution was as mixed astigmatism, 27 eyes, 75.00%, hyperopia 9 eyes, 25.00%, myopia 0 eyes ; The absolute value of astigmatism distribution, cylinder absolute value of 3.50D-4.75D, with an average of 4.00D. Conclusion Preschoolers Sure-sight vision screening instrument examination cylinder was ± 9.99D are astigmatism, the absolute value of 3.50D-4.75D, with an average of 4.00D, mainly to mixed astigmatism.
