在很多国家,医生将阿托品用于弱视治疗。阿托品可以麻痹眼肌,扩大瞳孔,使眼睛聚焦功能瘫痪,从而降低好眼视力。

阿托品的作用类似于眼罩,或者半透明眼镜。遮盖时,孩子可以把眼罩摘掉,但阿托品就不存在这个问题,也不会影响美观。虽然有研究表明,阿托品和全天遮盖疗效相同,可对我来说,阿托品危害更大。

这是因为,阿托品相当于“无法摘掉的眼罩”,而且需要长期使用,甚至可能会超过一年,即使停药后,阿托品对眼睛聚焦功能的损伤,还会持续很久。

而且就像其它作用于中枢神经的药物一样,阿托品也有许多副作用,如眼睛红肿、口干、排尿困难和便秘等。

根据普雷斯医生,阿托品之所以有效,是因为它利用了MFBF原理,即双眼视野下的单眼精细训练。换句话说,就是通过人为降低好眼视力,强迫大脑使用弱视眼。

相对于阿托品和全天遮盖,这些方法没有风险,也没有副作用。阿托品不应该是首选、或者唯一的弱视治疗方法。
