先天性睑内翻与形觉剥夺的临床关系

Relationship between form deprivation and congenital entropion

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 investigate the relationship between form deprivation and congenital entropion.Methods In a retrospective study of 24 children (45 eyes) with congenital entropion, patients were divided into two groups. Patients in group A were 4~6 years old, those in group B were 7~15 years old. Refractive status, amblyopia and corrective ocular disorders were examined.Results The incidences of myopia were 63.64% (14/22) and 88.00% (22/25) respectively in group A and B. Both were higher than those of general children in the same age (P<0.01).The morbidities of myopia, high myopia, degeneration of ocular fundus in group A were higher than those in group B (P<0.05). Of total 45 eyes with congenital entropion,the incidence of amblyopia is higher than that of general children (P<0.01). Conclusion Congenital entropion may lead to form deprivation and increase the occurrence of myopia and amblyopia. It should be corrected by surgery soon after being diagnosed.
