如何防止弱视复发?

     

       弱视的根本病因——双眼竞争,大脑视觉抑制。弱视的治疗,也要针对病因治疗。

 

       行之有效的弱视治疗,分三个阶段。

 

         Monocular Therapy单眼训练阶段


        Monocular Training in a Binocular Field双眼视野下的单眼精细训练阶段


        Binocular Therapy双眼训练阶段

 

       有的宝妈很苦恼,我家孩子也遮盖,为什么弱视眼视力提升这么慢呢?为什么提升之后还会出现弱视复发呢?怎样防止弱视复发呢?

 

When only a patch is used to cover the good eye, it is like putting the brothers in separate rooms. When we do this, the acuity of the amblyopic eye often improves, but then after the patch is removed the visual acuity in the amblyopic eye goes back to its lower level. Why? Because the bully brother never learned to cooperate with his less assertive brother so he again reverts back to his old ways and prevents the less assertive brother from speaking.

只用眼罩遮盖好眼,就好像把两个兄弟放在不同的房间。这样可以提高弱视眼的视力,但停止遮盖后,弱视眼的视力又发生回退。为什么会这样?因为霸道哥哥没有学会和弟弟和平相处,会继续阻止弱小的弟弟说话。

In the program of optometric vision therapy when the eye is patched, we do monocular exercises to make the less assertive eye more like Rambo. Then,when the eyes are put together, it is more likely that the bully will accept him. Once this occurs we teach them to work effectively together, like brothers should, in their communication with mom. We make each of the eyes work well separately, and most importantly, we teach them to work together! This takes time and training, but if done well, the results will last for a lifetime. It makes perfect sense, doesn’t it?

在行为视觉训练过程中,遮盖住好眼,我们对弱视眼进行训练,让它变得更强壮。这样,当双眼重新在一起之后,霸道的哥哥更容易接受弱小的弟弟。只要霸道的哥哥接受了弟弟,我们就教他们一起工作,就像哥哥和妈妈交流一样。这样,不仅增强了每只眼睛的功能,最重要的是,我们教会双眼同时工作!这一过程需要时间,需要进行视觉训练,如果效果良好,那么这种治疗效果会伴随一生,造福一生。这非常有意义,不是吗?

A scientific study by Drs. Firzgerald and Krumholtz at the State University of New York, State College of Optometry illustrates this point. They studied how well visual acuity gains from treatment were maitained 1-2 years after the treatment was concluded. What they found was quite dramatic. In patients who received optical correction (glasses) only, 50% lost some or all of their visual acuity improvement. In the group that received optical correction, occlusion, and optometric vision therapy, 100% maintained their visual acuity improvement!

Firzgerald博士和 Krumholtz博士,在美国纽约州立大学眼视光学院发表的研究,就说明了这一点。在治疗结束后,通过治疗获得的良好视力,能维持12年。他们的研究结果,治疗差异非常大。只进行光学矫正(佩戴眼镜)的患者中,50%的患者出现视力回退现象。而进行光学矫正、遮盖和视觉训练的患者,所有患者视力都没有回退!

They concluded, “ Maintenance of visual acuity gains were best if vision training is an integral part of the treatment plan and there was a strong relationship between improvements in stereopsis (good binocular vision) and the maintenance of visual acuity gains over time.”

他们的研究结论是,在治疗过程加入视觉训练,可以防止视力回退。并且,立体视的提高(良好的双眼视),和训练后提高的视力的维持,两者之间有很强的关系。

To summarize, the problem in amblyopia is not the eye, but the inability of the two eyes to co-exist together. This is why we say amblyopia is a problem of binocular competition. This is not a concept; it has been known for some time. Dr. Kenneth. J. Ciuffreda in his book, Amblyopia: Basic and Clinical Aspects, wrote about binocular competition being the major contributor to amblyopia more than 20 years ago!

总之,弱视不是眼睛的问题,而是两只眼睛不能同时使用。所有,我们说弱视是双眼竞争的问题。这不是新的概念,早在20多年前,《弱视:基础和临床应用》这本书里,Kenneth. J. Ciuffreda博士就写过,双眼竞争是引起弱视的主要原因
