查询词典 acuity

He syncopal signal symptom and physical sign of the induced and spontaneous VVS are similar in that both have the onset of nausea, cold sweat, pale complexion, the disappearance of posture tension, decrease of hearing acuity, lags in response, blurring in eyesight, sleepiness etc at the beginning.

Ort是VVS迄今为止的唯一确诊性技术。多年来，Ory是由受试者平卧于诊断床上，经过10～20ITtin休息后，受试者快速主动站立，然后测量其心率、血压并观察其临床表现，由此来评价VVS患者的自主神经反应。

Methods 11 cases loss UCVA or had optical aberration were undergone enhancement guided by corneal topograph , which included regression 5 cases、central island 3 cases、eccentric ablation 3 cases . Visual acuity and visual complication were followed for 6 months.

对11眼（11例）PRK术后出现视力不良者(其中偏心切削5例，角膜中央岛3例，屈光回退3例)在角膜地形图引导下进行个体化准分子激光切削，术后随访6月，观察视力和视觉症状。

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。

Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.

诊断/检测。对于皮肤色素沉着正常、中央凹发育不全、视敏度降低以及视径投射异常（VEP，表现为视觉诱发电位中皮层反应的交叉不对称）的男性患者，当存在先天眼球震颤、虹膜半透明以及显著的眼基底层边缘色素减退的症状时，可被疑似诊断为眼白化病。X连锁性遗传则以存在与X连锁遗传一致的家族病史，或在一个应当为携带者的女性中存在典型的携带者迹象（视网膜色素沉着不规则以及部分虹膜透射）而被确认。

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。

The hearing acuity recovered gradually and returned to normal 3 days later: The use of nitrous oxide during anesthesia was incriminated as the possible cause.

该病患之左侧耳听力逐渐恢复，手术三天后恢复正常。二氧化氮的使用为最可能的原因。

The AR200 group of laser measurement sensors is Acuity's most compact series of triangulating laser displacement sensors.

AR200激光位移传感器是一款最紧凑的三角法位移传感器系列。

The teacher likes the honeymouthed little girl very much.

老师很喜欢这个嘴甜的小姑娘。
