While a lack of clutter is always nice, you almost suffer "snow blindness" from the amount of white on the site.

You might have him tested for word blindness.

你可能要让他检查一下是否是字盲。

Well, I was born with a rare visual condition called achromatopsia, which is total color blindness, so I've never seen color, and I don't know what color looks like, because I come from a grayscale world.

我出生在一个色彩极少的世界，世界只有明暗之分，这叫做全色盲所以我不知道什么是颜色，也不知道颜色是什么样的，因为我来自一个灰色的国度。

Methods 31 patients with total blindness were treated by transfrontal craniotomy decompression of optic nerve, which allowed complete decompression of the optic canal, incision of optic sheath, and removal of apical orbital bone fragments.

方法应用额部开颅视神经减压开放术治疗术治疗术前完全失明（无光感）患者31例，全程开放视神经管及视神经鞘膜，并取出眶尖的碎骨片。

Currently around 10 million people worldwide each year require surgery to prevent corneal blindness, and another five million already suffer total blindness from corneal scarring caused by burns, lacerations, abrasion or disease.

目前全球每年有大约1000万人需要移植角膜来防止角膜盲。还有500万人由于烧伤、撕裂、擦伤或疾病导致角膜瘢痕而完全失明。

But even if half-hearted, it was a change that pushed Hut 8 off the knife-edge and into almost total blindness.

但即便是虚张声势，也是进行了改变，而且这项改变几乎导致8号营房完全失明。

The illness will result in total blindness if ( it is) left untreated.

如果不治疗的话，这病将导致完全失明。

It does not affect peripheral vision, but the loss of clear central vision can rob a person of the ability to read, drive and recognise people's faces even without causing total blindness.

这种病不影响外周视力，但是明显的中心视力的丧失会剥夺患者阅读、驾驶的能力，甚至即使没有出现全盲的情况下也会是患者不能认出别人的脸。

A clinical trial is being launched in three African countries of a drug that could eliminate onchocerciasis, or river blindness, one of the leading infectious causes of blindness across Africa.

盘尾丝虫病或者河盲症是整个非洲存在的一个主要致盲性传染病，一种可以用来消灭该病的新药目前在3个非洲国家进入临床试验。

The findings suggest that it could be possible to develop a vaccine that protects people against river blindness using a similar approach, though the scientists point out that more research is needed.

这项发现表明，用类似的手段或许可能开发出人用盘尾丝虫病疫苗，不过科学家指出这还需要进行更多的研究。

The campaign to eliminate river blindness began as the most vertical programme imaginable: helicopters dropping insecticides out of the sky.

根除河盲症运动开始时是可以想象的最纵向的规划：直升飞机从空中投撒杀虫剂。

The current treatment for river blindness is the drug ivermectin, which kills larval parasites but not the adult worms.

目前治疗盘尾丝虫病的手段是使用一种叫做伊维菌素（ivermectin）的药物，它杀死幼虫，但是对成虫无效。

Another one is called trachoma, or river blindness.

另外一种疾病是沙眼，也叫做河盲。

For example, the river blindness control programme began as a vertical programme, but eventually developed the community-directed approach for drug distribution.

例如，河盲症控制规划一开始是纵向规划，但最后发展成为以社区为方向的药物分配办法。

Dramatically reduced the scourge of river blindness ( onchocerciasis);

大大减轻了河盲症（盘尾丝虫病）祸害；

A study has identified a gene responsible for Leber Congenital Amaurosis ( LCA), the most common cause of congenital blindness in infants and small children.

最新的一项研究确定了一个与先天性黑朦（LCA），一种婴儿和低龄儿童最常见先天性失明的原因，相关的基因。

Objective: To detect gene mutations associated with autosomal dominant congenital stationary night blindness ( ADCSNB) in a large Chinese family.

目的：检测中国一常染色体显性先天性静止性夜盲（ADCSNB）大家系相关基因的致病性突变位点及此病临床表型特征。

Congenital colour-blindness and deficiency of glucose-6-phosphate dehydrogenase

先天性色盲与红细胞葡萄糖6-磷酸脱氢酶缺乏

The congenital cause of blindness ( 3) makes up 4% of the total.

引起盲的原因主要是先天性致盲3例，占4%。
