查询词典 myopia

AbstractAIM: To study the changes of refractive status and axial length in chicken form deprivation myopia and its recovery model, to observe the metamorphism of posterior sclera and to lay foundation for investigation of axial myopia pathogenesisMETHODS: Twenty-five newly incubated chicken were selected. Their left eyes were covered with semi-translucent membrane to deprive form perception for 14 days (form-deprivation group), or covered for 11 days followed by uncovered for 3 days. Unoccluded eyes in either group served as control eyes respectively. Retinoscopy and A- ultrasound were conducted to collect the refraction and axial length data.

目的：研究雏鸡形觉剥夺性近视眼及形觉剥夺性近视眼恢复模型的屈光状态和眼轴长度的变化，并观察后极部巩膜的形态学改变，为探讨轴性近视的发病机制打下基矗方法：选用新孵出的普通肉食家鸡25只，采用半透明薄膜眼罩遮盖的方法对左眼进行形觉剥夺14d或遮盖11d后，去遮盖3d。

But in fact, vitamin A effects on vision has nothing to do with myopia, which mainly affects the eyes in the dark light, vision (so-called "dark adaptation"), vitamin A deficiency can lead to a reduced ability to dark-adapted (the worst case, can cause night blindness), but also will lead to eye conjunctiva (commonly known as "white eye" part) or the cornea (commonly known as "black eye" part) of the damage, but does not cause myopia.

但实际上，维生素A对视力的影响与近视无关，它主要影响眼睛在暗光下的视力，维生素A缺乏会导致暗适应能力下降，还会导致眼睛结膜或角膜的损害，但不会引起近视。

Results analysis of data indicated a significant positive correlation among the refraction dioptres of myopia and axis length,vitreous length of eye (standardized coefficients are 0.909 and 0.803,respectively). multiple linear regression analysis of the data showed that vitreous length was the main factor to affected the formation and development of myopia diopter.

结果 眼轴长度（标准化回归系数b'j =0.909）及玻璃体腔长度（标准化回归系数b'j =0.893）均与近视屈光度呈显著正相关；用逐步回归多元线性分析法分析玻璃体腔长度、晶体厚度及前房深度各屈光要素，其中玻璃体腔长度对眼轴长度的影响最大。

Results The experimental eyes quickly changed from pre-experimental hypermetropin to high myopia during the experimental period, and the severity of myopia and axial length increased relative to the period of form deprivation. The expression of VIPR2 mRNA and the levels decreased over time for both groups.

结果 实验组由实验前远视眼快速演变为高度近视眼，并随遮盖时间的延长、近视度数的加深，眼轴延长；两组眼球后壁均有VIPB2 mRNA的阳性表达；随着出生时间的延长，两组VIPR2 mRNA的表达均逐渐下降。

the growth of length of axis oculi was the most important factor for the formation and development of axial myopia ,especially in pathological myopia,which is basically the prolong of vitreous cavity.

眼轴增长是近视眼发生、发展的重要因素，尤其对中、高度近视眼作用更为显著；眼轴长度的增长基本为玻璃体腔的延长。

High accommodative lag in the nearwork may be one of the reasons leading to myopia progression.

近距离工作时高调节滞后可能是导致近视进展的原因之一。

Our study was to explore the relationship between high myopia of albino guinea pig and the expression of retinal dopamine.

目的 观察白化豚鼠视网膜多巴胺的表达，探讨其视网膜DA与高度近视的关联。

METHODS: LASIK with Allegretto excimer laser and Moria-M2 microkeratome were performed on 1 100 patients with myopia (2 151 eyes).

使用Allegretto准分子激光机和Moria-M2微型角膜板层刀，连续对1 100例近视者（2 151眼）实施常规LASIK手术矫正。

Myopia is a leading cause of ametropia throughout the world.

近视是目前全球发生率最高的屈光不正。

Myopia is the main cause of ametropia in students.

引起中小学生视力下降的主要原因是近视，做好近视防治工作，对控制中小学生视力不良有重要意义。

The network space is the typical form of abstract space when it comes to the digital stage.
