目的 了解先天性睑内翻与形觉剥夺的关系 ,并由此进一步探讨先天性睑内翻的手术时机。方法 回顾 2 5例47眼先天性睑内翻病例 ,将其分为学龄前组 (11例 2 2眼 ,4～ 6岁 )和学龄组 (14例 2 5眼 ,7～ 15岁 ) 2组 ,分析其屈光状态、弱视情况及相关眼部病变。结果 学龄前组和学龄组近视患病率分别为 6 3.6 4%和 88.0 0 % ,均高于相同年龄段我国儿童总体患病率 (0 .5 0 %～ 2 .0 7% ,11.0 0 %～ 36 .40 % )(P <0 .0 1)。且学龄组近视 (88.0 0 % )、高度近视 (4 8.0 0 % )、近视性眼底病变 (36 .0 0 % )的患病率高于学龄前组(6 3.6 4%、18.18%、9.0 9% ) (P <0 .0 5 )。 2组合计弱视患病率 (4 0 .43% )高于我国儿童总体患病率 (2 %～ 5 % ) (P <0 .0 1)。结论 先天性睑内翻可能会产生形觉剥夺并可能导致近视和弱视 ,发现后宜尽早手术根治。
Objective To understand the relationship between congenital ectropion and form deprivation, and to further explore the timing of congenital ectropion. Methods Twenty-five cases (47 eyes) of congenital ecchymosis were retrospectively divided into two groups: preschool group (11 cases, 22 eyes, 4 to 6 years old) and school-age group (14 cases, 25 eyes, 7 to 15 years old) , Analysis of refractive status, amblyopia and related ocular lesions. Results The prevalence of myopia in pre-school and school-age groups were respectively 6 3.6 4% and 88.0 0%, which were all higher than those in the same age group (0.50% -2.07%, 11.0% ~ 36 .40%) (P <0. 01). The prevalence of myopia (88.0%), high myopia (4.080%) and myopia in the school-age group (36.0%) were higher than those in the preschool age group (3.636%, 18.18%, 9.09 %) (P <0. 05). The combined prevalence of amblyopia (40.03%) was higher than the overall prevalence of children (2% -5%) in our country (P <0.01). Conclusions Congenital ectropion may result in deprivation of form and may result in myopia and amblyopia, and should be treated as soon as possible after operation.
