护眼的十一大疑惑 这段时间比较忙。上个月的Zoom 分享,现在才整理出来了。很多家长对孩子近视很担心。这里做了一些解说和解惑。 我们以前10岁才近视,现在孩子6岁就近视了。一年长75度到一百度,到成人了,那不变成1000度?在那个度数,视网膜会更脆弱,容易脱落,也不能做激光手术了。 那近视发展,可以停止吗? 近视其实有三个原因,妈妈怀孕期营养影响/难产, 看近的小字和符号多/眼睛压力多,或者双眼不协调/视功能失调。 双眼视功能失调可以是因为集中不够,调节不够或两眼微小动作不同步。如果不治疗好,近视会快加深很多。双眼视功能失调可以做视觉训练矫正, 减少近视发展。视觉训练目前还可以做脑震荡眼脑康复治疗, 视觉上的学习障碍,和提高运动员的速度和反应能力 (耳聪目明)。视觉训练在美国开始,现在在广州中三眼科医院有提供。在美国可以在  上找,Boston Children’s Hospital 也开始做了。在加拿大可以在 上找。视觉训练通常由进修做眼脑发展和复建的视光眼科医生 (Developmental and Rehabilitative Optometrist) 和他的视觉训练员做。 如果近视是只是由用眼多的压力造成的,那视觉训练就不够效果。 要一直做下去才好。 这种情况,可以做OK 镜,效果会好很多。做OK 镜前,要找做眼脑发展和复建的视光眼科医生详细检查,确认没有双眼视功能失调才有效果。 下面是在家长群里的问题收集和我的回答: Q1. 青少年带隐形眼镜有什么危害吗?如果佩戴怎么选择? Dr. Liang, 我以前是常说隐形眼镜没什莫伤害,这主要是我的病人没有什么感染的情况。其实在青少年来说,普通白天戴的隐形是比成人的感染多一些。在中国,也比北美的情况严重些。在北美,风险是1-2%而已。我每个病人都要做个Contact Lens Fitting, 新手要做个 contact lens teach, 教会他们好的,规范的佩戴和清洁习惯,就减少了很多感染和不适。Contact lens fitting 是由视光医生做的,挑的隐形就比较适合孩子,以后再每年检查的就基本很少感染。OK 镜来说,是比较透气的,是晚上睡觉的时候戴的。洗的干净和规范,就减少很多感染。 Q2. 青少年戴远视眼镜,需要防止近视吗?远视眼如何注意保护眼睛,维持正常视力? Dr. Liang, 近视的人眼睛比较长,看到的都投影在眼睛视网膜的前面。 远视的人眼睛比较短,看到的都投影在视网膜的后面。和近视是相反的。远视的孩子需要每年验眼检查。 他们有些像有老花的人那样,看近的,会不清楚,或者逃避看书。做验眼检查就可以看到他们的眼睛视功能会不会也受到影响了。 Q3. OK镜的最佳佩戴年龄,激光手术针对近视者是一劳永逸的吗?术后会有什么副作用?20岁的女孩是佩戴OK镜适合还是激光手术更适合?...

Six Home Care Tips for Eye Fatigue

当医生说孩子近视了?你说该有什么反应?你会有什么反应? For every action, there is a reaction. For a bigger reaction, something even bigger follows. 每个大反应的人,都浪费了自己和孩子很多时间,和心情。 我看到的一些反应,有些是很奇妙的,有些是我以前没想到的。 先说我自己吧,我10岁 -0.75度近视,我妈没让我戴眼镜。她被人骗了,让我喝一些很贵的鱼骨, 还好没喝坏,然后按摩耳朵。我11岁了,才戴上,是最便宜的,我不喜欢。我那时候喜欢金丝眼镜。然后11-14岁,他没空理我。我带那很土的眼镜,都被人校园暴力了。15岁被我爸打了,眼镜坏了,才验眼,换了眼镜。后来,我自己去验眼,18岁配隐形,在视光眼科诊所打工,然后就成了现在的我,一名一直在成长的视光眼科医生。而且,现在还喜欢戴眼镜。 我见过验眼时怀疑孩子捣蛋,不喜欢认真看视力表的,结果花掉医生和她/他自己很多时间。 我见过验眼前就叮嘱孩子戴眼镜不好看的,结果孩子一进诊室就害怕,不合作。到最后,需要时,不想戴眼睛。有些孩子还造成紧张,瞳孔肌肉痉挛(accommodative spasm),和短暂的假性近视 (pseudo myopia), 也是花掉她/他自己很多时间。 也有当时来的家长接受了孩子近视,回家和家人说了,家人不接受,要多处重新测,也是浪费了一家人很多时间。 没有什么反应是应该的。 但是,比较轻松一点的活法就是,接受,然后看看有什么控制近视的方法。 这里也有人很纠结,有些在孩子9岁就800度的时候,还在考虑要不要控制近视。(要50-100度就考虑了)。 反正,现在70%的加拿大大学生都近视,90%的中国大学生都近视 (你没看到,他们可能戴隐形了,或做了OK镜。) 孩子读完书之前,不建议做激光手术。 但很多时候,家长们都很纠结。这,其中也有他们自己的儿童时期,父母也可能很纠结。但是,请意识到,不是戴眼镜就越带越深,是没有矫正下,用眼过多,近视会越来越深。 现在有很多好看的眼镜,也有很多控制近视的方法。这些,都不是问题。 还是想太多了?那请找视光眼科医生解惑。 这里先说近视的一大惑:近视怎么来的? 婴儿期近视:孩子一出生就高度近视。这可能是怀孕期的影响,或营养影响。 压力造成近视:孩子很早就开始读书,或看很小的字或符号。 双眼不协调造成的近视: 孩子眼睛视功能发展不好,读书造成高度的压力,眼睛轴度变长,近视加快。 这第三种情况,其中双眼不协调造成的近视是很容易用眼科视觉训练就能治好的。双眼不协调的孩子,他们的眼睛不合作,或调节不够,集中不够,就会造成很大的压力,造成近视快速加深。 他们的情况,每个都可能不一样。要做个人定制的眼科视觉训练才能治好眼睛的协调性,减少近视加深。 而第二种,压力造成的近视,做眼科视觉训练的效果不适合,效果少一些。 要一直做才有效。这种近视适合做OK镜(orthokeratology)。   OK镜是晚上睡觉时戴的,白天可以摘下来。运动的孩子也很方便。这控制近视的效果,和对的人,是挺好的。 更多资料, 请看眼科视觉训练。...
