查询词典 acuity

Oculocutaneous albinism type 4 (OCA4) is characterized by hypopigmentation of the skin and hair plus the characteristic ocular changes found in all other types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual acuity; and misrouting of the optic nerves at the chiasm associated with alternating strabismus, reduced stereoscopic vision, and an altered visual evoked potential.

疾病特征： 4型眼皮肤白化病（OCA4）的特点是皮肤和头发的色素减退以及所有白化病类型都有的典型的眼部改变，包括眼球震颤、虹膜色素减少而使其呈半透明状、视网膜色素减少而使得脉络膜血管在眼底镜检时可见、与中央凹发育不全导致的视敏度降低以及视神经交叉处路径错误引起的交替性斜视、立体感降低和视觉诱发电位改变。

The value of polar resources,scientific research and environmental is meaningful to human future.Above all,huge number of mineral and biological resources as well as the channel resources which would change the framework of the world.All of this,come into notice to the worl.Along with increasing acuity issue of the scarcity of resources and the energy crisis etc.Many countries adopt active polar policy to advance native political status and protect polar rights and interests,Which contains from politics,law,diplomatic,science expedition and environmentalism and etc.

极地的资源价值、科研价值和环境价值对人类的未来发展有重大意义，尤其是数量庞大的矿物和生物资源，以及能够改变世界政治经济格局的航道资源，这些资源近年来引起了世界各国的强烈关注。20世纪以来，随着资源紧缺、能源危机等问题日益尖锐，各国纷纷采取积极的极地政策，从政治、法律、政策、外交、等方面入手，提升本国的极地政治地位、保护在极地的权益、扩大影响力。

Methods:The visual acuity of 1146 children(2291 eyes,1 month～3 years) were determined with retinoscopy after tropicamide cycloplegia.

用托品酰胺眼液麻痹睫状肌后，对 1146名 1月～ 3岁婴幼儿的 2 2 91眼进行视网膜检影验光，并对其中的 5 6 0眼散光进行统计学分析。

The baseline examination included visual acuity, subjective refraction, Maddox Wing test (Clement Clarke International Ltd, Harlow, UK), partial coherence interferometry, slit lamp examination, automated refraction in cycloplegia, an oral questionnaire, and a cycle ergometer test.

基本检查包括视力、主观验光、马多克斯翼检查（英国Harlow Clement Clarke国际公司）、部分相干干涉测量法、裂隙灯检查、睫状肌麻痹后自动验光、一份口头调查问卷以及蹬车运动试验。

For monitoring the quality of the study, agreement test for visual acuity and cycloplegic auto-refraction between the two teams during the pilot study and the formal field study.

因为1998研究结果提示自动验光结果与视网膜检影一致性良好，因此2000年纵向研究中取消了睫状肌麻痹后的视网膜检影。

Methods Sixty students(120 eyes)with myopia(within-2.50D)were selected.visival acuity,cycloplegic refraction,keratometer,ocular axis,stereoscopic vision,and phoria strabismus were observed before and after 1～1.5 years wearing Anti-myopia Glasses.

近视的发生和发展与环境的影响密切相关[2]，特别在青少年时期，过分的和不适当的阅读、书写、观看电脑屏幕及其他近工作，是促成近视的重要因素[3]。

After 1-month treatment, his best corrected visual acuity improved from 0.05 initially to 1.2, and the corneal thickness was not different between eyes. Nevertheless, at the injured sites, cornea was apparently thicker and corneal endothelial densities were lower than those in the fellow eye. This cornea might decompensate after any other ocular trauma or intraocular surgery.

经过一个月的治疗后，视力、眼压、中央角膜厚度、角膜上皮、前房、视网膜等皆恢復正常，但角膜內皮细胞密度明显减少，受伤部位的角膜亦明显较厚，日后恐有角膜失偿的危险，而这种情况无法藉测量中央角膜厚度显示出来。

Cornea is a component of the ocular dipotric system, it is the main reflecting interface of the eye, its high diaphaneity is the basis for good visual acuity and inhibiting light from scattering.

作为眼球的屈光系统成分之一，角膜是眼的主要反射界面。角膜的高透明度是抑制光线散射、保持健康视力的重要基础。

Objective: To investigate clinical significance of heterophoria dimensionality in pilots with normal visual acuity.

目的：探讨正常视力飞行员隐斜度数的临床意义。

The best corrected visual acuity, diopter and complications after the operation were observed.

术后观察患者最佳矫正视力、屈光度数和手术并发症。

Continuously improve the production mechanism, to provide customers with better quality products and services.

不断的完善生产机制，给客户提供更优质的产品及服务。
