目的:了解儿童眼散光的主要类型、分布规律、视力矫正情况及影响弱视程度的因素。方法:对983例3～7岁视力低常儿童1767眼散瞳验光所得散光情况进行统计分析。结果:复性远视散光占64.35%,混合散光占15.90%,复性近视散光占9.39%,单纯远视散光占9.05%,单纯近视散光占1.30%。散光程度在0.5～1.00DC者占43.41%,1.25～2.00DC者占34.35%,2.25～3.00DC者占14.88%,3.00DC以上者占7.36%。双眼散光占79.76%,单眼散光占20.24%。矫正视力≥0.9者占44.93%,矫正视力(0.9者占55.07%,确诊弱视649眼,占36.73%。结论:儿童屈光不正以散瞳状态为主,复性远视散光是儿童眼散光的主要类型,散光程度以轻度为主,中、重度散光是弱视形成的主要原因,应早期筛查视力低常儿童的屈光状态,合理矫治儿童眼散光。
Objective: To understand the main types of children’s astigmatism, distribution, vision correction and the impact of the degree of amblyopia factors. Methods: A total of 983 children aged 3 to 7 years old with visual acuity 1767 eyes were collected cycloplegic optometry astigmatism statistical analysis. Results: Refractive hyperopic astigmatism accounted for 64.35%, mixed astigmatism accounted for 15.90%, reflex myopic astigmatism accounted for 9.39%, hyperopia astigmatism accounted for 9.05%, simple myopia astigmatism accounted for 1.30%. Degree of astigmatism in 0.5 ~ 1.00DC accounted for 43.41%, 1.25 ~ 2.00DC accounted for 34.35%, 2.25 ~ 3.00DC accounted for 14.88%, 3.00DC and above accounted for 7.36%. Eyes 79.76% astigmatism, monocular astigmatism accounted for 20.24%. Corrected visual acuity ≥0.9 accounted for 44.93%, corrected visual acuity (0.9 accounted for 55.07%, 649 eyes were diagnosed amblyopia, accounting for 36.73% .Conclusion: Amblyopia in children with mydriasis, reflex hyperopicosis astigmatism is the main Type, degree of astigmatism with mild, moderate and severe astigmatism is the main reason for the formation of amblyopia, early vision screening of children with low refractive status, reasonable correction of children with astigmatism.
