查询词典 visual acuity

The macular micropathology was the main factor in infecting visual functions after cataract phacoemulsification. OCT is a new technique of retinal tomography with sensitive resolving power, It is very valuable in the early diagnosis of macular micropathology with low visual acuity, follow-up and futher treatment after cataract phacoemulsification.

手术前视力1只眼为光感，1只眼为眼前手动，1只眼为数指/10 cm，1只眼为0.02，12只眼不能配合视力检查，对强光刺激反应不明显。13只眼行晶状体切除和前段玻璃体切割，1只眼1期植入人工晶状体， 3只合并视网膜脱离眼行晶状体切除、玻璃体切割、眼内激光光凝、注气、巩膜环扎手术。

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。

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。

On the basis of theories of high-level visual processing subsystems and by following Sternberg's element-adding study pattern, serial studies were made to investigate the plasticity of visual cognitive ability in space. The results show that different degrees of plasticity and stability do exist in the cognition processing of visual space. Moreover, plasticity and flexibility in judgments of appearance swirl and quantitative spatial relationship and in command of visual characteristics are found greater in these studies than those obtained by means of appearance scanning, movement inference and judgment of categorical space relation.

视觉空间能力认知可塑性系列研究以高水平视觉加工子系统理论为基础，以斯滕伯格的加因素法为研究范式，通过对视觉空间任务的练习效应与年龄效应的检验表明，视觉空间认知加工中存在着的不同程度的可塑性与稳定性，结果显示出表象旋转、数量空间关系判断和视觉特征提取任务明显要比表象扫描、运动推断以及类别空间关系判断表现出较强的可塑性和易变性特点。

The system consists of two modules: visual clustering analysis and visual data classifying, with respect to clustering algorithms and classifying algorithms, in which the visual technology of parallel coordinates is combined to obtain better visual data mining effects.

将聚类算法和分类算法与平行坐标的可视化技术结合起来，达到更好的可视化数据挖掘效果。

In order to develop visual mechanical design software with the functions of design computing , database management and automatic graph plotting, this paper studies the multi-platform technologies such as Visual Basic 6.0, Visual FoxPro 6.0, Visual LISP and AutoCAD, in which interface programming, directory structure design and rational use of platforms areincluded.

为开发具有设计计算、数据库管理和自动制图功能的可视化机械设计软件，对Visual Basic6.0、Visual FoxPro6.0、Visual LISP和Auto CAD多平台开发技术进行了研究。该技术主要包括接口程序设计、目录结构设计和平台的合理使用。

Based on physical and psychological theories of driver's dynamic vision, combined related research methods and conclusions in home and abroad, the basic modes and characteristic parameters of driver's visual behavior were discussed systemically. Several indexes were determined as basic characteristic parameters of dynamic visual search mode, including fixation duration, visual angle, visual search scope, saccade amplitude and saccade velocity.

在驾驶员动态视觉生理学和心理学理论的基础上，结合国内外相关领域的研究方法和研究结论，对驾驶员视觉行为的基本形式和表征参数进行了系统的论述和分析，确定以注视持续时间、视角、视觉搜索广度、扫视幅度和扫视速度几个指标作为动态视觉搜索模式的基本表征参数。

This essay used semeiology and metaphor theory as well as real examples, to discuss the problem of how the meaning raised from the visual language in the information design, which including two different angles: the structure of visual language, and the pedigree of the visual language itself; and then to discuss the receivability of visual language in the view of language deciphering.
