结果：手术后1个月时，4只眼（占27%）获得了20/10以上的超常视力。

The superolateral near limbus incision would effectively minimize the wound - stretching forces and result in earlier lesser degree of corneal astigmatism and better uncorrected visual acuity postoperatively.

The albinism is characterized by hypopigmentation of the skin and hair and the ocular findings of reduced iris pigment with iris transillumination, reduced retinal pigment, foveal hypoplasia with significant reduction in visual acuity (usually in the range of 20/50 to 20/400), nystagmus, and increased crossing of the optic nerve fibers.

白化的特征有：皮肤与头发的色素减退以及一些眼科症状，包括虹膜透照显示出的虹膜着色减弱、视网膜着色减弱、中央凹发育不良且视觉灵敏度显著减弱（通常在20/50至20/400的范围）、眼球震颤和视神经纤维交叉增加。

The outcome of visual acuity was poorer in patients with the following conditions:no light perception after trauma（P=0.0069）,loss of consciousness（P=0.003）,fracture of the opticcanal,and absence of VEP.Conclusion Traumatic optic neuropathy included diˉrect and undirect injury type.

伤后视力无光感比有光感以上视力（P=0.0069）、伤后有昏迷比伤后无昏迷（P=0.0030）、伤后视神经管骨折比无骨折、视觉诱发电位检查熄灭型比非熄灭型最终视力的恢复危险度增加。

And they were visual acuity, contrast sensitivity function, accommodation and vergence ocular optical aberration and cortical topography.② From the general data collection, the volume of refractive surgery was in the development curve from sharp up to flat up trend, LASIK was the domain one.

结果 从以不同角度设计的临床基础研究中总结出与视觉功能有关的参数，主要有视敏度和对比敏感度视力、调节和辐辏功能参数、眼球像差、角膜形态参数。

Extracellularly recording the responses of dLGN neurons to sinusoidal gratings with different orientations showed that optimum orientations of dLGN neurons in trained cats, compared with that in untrained cats, did not shift in favour of the trained orientation. For cells with receptive fields located within 15°visual acuity away from the foveae, there are no difference in orientation bias and firing rate at trained orientation between the trained cats and untrained cats.

细胞外记录外膝体背核神经元对不同方位正弦光栅刺激的反应显示，垂直或水平方位正弦光栅信号训练的猫，与正常猫相比，其外膝体细胞的最优方位并未向着训练方位发生明显改变，对于感受野位于中央区15 度视角以内的细胞来说，其方位选择性强度以及在训练方位的发放强度与正常猫无明显差异。

The postoperative stimulated symptoms, uncorrected visual acuity, refractive power, time of epithelial healing and corneal hazes were observed and analyzed.

比较两组术后刺激症状、角膜瓣或角膜上皮瓣制作及愈合情况、术后视力变化、术后屈光度变化、术后散光度变化以及并发症。

Results The average onset age of moyamoya disease was very young. Female was dominant in our studied. Younger patients with moyamoya disease mainly suffered cerebral ischemia (87.5%). Adult patients suffered more cerebral hemorrhage (41.2%). Among clinical manifestations, headache, vertigo, paralysis, hemiplegia or alternative hemiplegia were common symptoms. Sometimes aphasia, dementia, visual acuity were decreasing, epilepsy and chorea minor might occur. 14 cases had received CT examination, but none was diagnosed moyamoya disease by CT. All patients received MRI and MRA examinations were diagnosed as moyatnoya disease.

结果 烟雾病发病平均年龄较轻，女性多于男性；少儿烟雾病患者以缺血改变为主(87.5%)，成年烟雾病患者缺血改变(58.8%)与出血改变(41.2%)相当；临床以头痛、头晕、肢体无力或偏瘫或交替性瘫痪为主要表现，同时可伴失语、智能下降、视力下降、癫痫发作、小舞蹈发作等表现。14例行头CT检查仅示颅内病灶，均未提示烟雾病；25例均行MRI和MRA检查发现颅内病灶，显示颈内动脉虹吸末段和大脑前或中动脉近段狭窄或闭塞，并有脑基底部异常血管网及侧支循环形成，均被诊断为烟雾病。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
