目的:对传统弱视定义的缺陷进行研究与修订。方法:1通过对已被确诊为弱视的病人进行鉴别诊断及进一步神经学检查,验证其是否确为弱视.2对大样本幼儿视力进行连续追踪调查,探讨视力发育与年龄的关系。3对大样本弱视病人的眼部其他疾病进行检查.结果:1确诊弱视的前提条件是鉴别诊断,排除神经系统疾病.2视力标准应考虑被检对象的年龄因素.不同年龄阶段应采用不同标准.3弱视并非“眼本身无器质性病变”.远视、近视、斜视、屈光间质混浊等都属于器质性病变,恰恰是这些器质性病变属于弱视的成因.结论:Bangcrter弱视定义应予修订。本文提出定义如下:弱视是视觉发育过程中受到某些因素的干扰、剥夺与抑制而未能得到适宜的视觉刺激,在微观水平与分子水平深刻变化基础上形成的发育障碍。
Objective: To study and revise the defects of the traditional definition of amblyopia. Methods: 1 Through the differential diagnosis of patients who have been diagnosed with amblyopia and further neurological examination to verify whether it is indeed amblyopia.2 A large sample of children underwent continuous follow-up vision survey to explore the relationship between visual acuity and age. 3 A large sample of amblyopia patients with other eye diseases were examined.Results: 1 amblyopia diagnosed as a prerequisite for the differential diagnosis, excluding neurological disease.2 Vision standards should be considered the age of the object to be seized.At the different ages should adopt different standards .3 Amblyopia is not “the eye itself is no organic disease.” Hyperopia, myopia, strabismus, refractive mesenchymal opacity are organic disease, it is precisely these organic diseases are the causes of amblyopia.Conclusion: The definition of amblyopia Bangcrter Should be revised. This article proposes the following definitions: Amblyopia is a developmental disorder caused by the interference, deprivation and suppression during visual development which can not get appropriate visual stimuli and is formed on the basis of profound changes at the micro and molecular levels.
