屈光不正性、屈光参差性及斜视性弱视儿童轮廓察觉比较

Comparison of contour integration among the children with ametropic amblyopia,anisometropic amblyopia and strabismic amblyopia

目的:探讨屈光不正性、屈光参差性及斜视性弱视儿童轮廓察觉特征及三者之间的差异。方法:选取在广西视光中心就诊的139例(237眼)弱视患者,按弱视类型分为屈光不正性弱视组40例(80眼)、屈光参差性弱视组61例(82眼)、斜视性弱视组38例(75眼),检测最佳矫正视力、轮廓察觉并对结果进行比较。结果:三组患儿弱视年龄构成无统计学差异(F=0.021,P=0.979),性别构成无统计学差异(χ2=3.229,P=0.199),最佳矫正视力比较无统计学差异(F=1.697,P=0.185),等效球镜无统计学差异(F=0.545,P=0.580),说明三组基线一致。三组患儿弱视轮廓察觉检测结果均集中在3级及3级以下,三组轮廓察觉结果比较,差异无统计学意义(Hc=4.416,P>0.05)。结论:屈光不正性、屈光参差性及斜视性弱视儿童均存在轮廓察觉功能缺陷。

Objective：To explore the characteristics of contour integration in children with ametropic amblyopia,anisometropic amblyopia and strabismic amblyopia,compare the differences.Methods：139 patients with amblyopia（237 eyes） were selected from Optometry Center of Guangxi Zhuang Autonomous Region,then they were divided into ametropic amblyopia group（40 cases,80 eyes）,strabismic amblyopia group（61 cases,82 eyes） and anisometropic amblyopia group（38 cases,75 eyes） according to the types of amblyopia,their best corrected visual acuity and contour integration were detected,and the results were compared.Results：There was no significant difference in the proportions of age and gender of children among the three groups（F=0.021,P=0.979）（χ2=3.229,P=0.199）.There was no significant difference in the best corrected visual acuity and spherical equivalent refraction of children among the three groups（F=1.697,P=0.185）（F=0.545,P=0.580）.The baselines of the three groups were the same.In the three groups,the detection results of contour integration of amblyopia were mainly at level three or below,there was no significant difference in the result of contour integration（Hc=4.416,P0.05）.Conclusion：Contour integration deficit are found in the children with ametropic amblyopia,anisometropic amblyopia and strabismic amblyopia.
