2、视知觉训练,2组均配合常规遮盖疗法,训练3个月.对比2组弱视眼最佳矫正视力(BCVA)及双眼的对比敏感度变化,相关数据采用方差分析和t检验.对比敏感度的比较进行Bonferroni校正检验。结果经过1个月的训练,2组弱视眼视力均有提高.B组提高优于A组,差异有统计学意义(一2.405,P<0.05)。训练3个月后,2组视力及对比敏感度均有提高.其中B组视力提高较A组更为明显,差异有统计学意义(=一2.883,P<0.05),并且B组中单眼弱视患者的相对“健眼”中频区的对比敏感度也有显著提高(=一3.580,P<0.00
3、83)。结论基于网络云计算的视知觉训练能快速有效地提高弱视患者的视功能,有望成为弱视治疗的一种新方法。【关键词】弱视;网络云计算;视知觉训练;对比敏感度ApplicationofthevisualperceptiontrainingsystembasedoncloudcomputingintreatmentofamblyopiaZhangJing,FengLixia.Departmentofophthalmology,theFirstAffiliatedHospitalofAnhuiMedicalUniversity,
