近视

Methods. PSF 1000 analyzer was used to measure retinal image quality for eye of 26 subjects (spherical ranged from –3.00 ~-6.00Ds, astigmatism ranged from –0.75~-3.00Dc) fitted with three forms of full correction in random order : unaided eye, with rigid gas permeable contact lenses and toric soft contact lenses. The modulation transfer function curve was observed, 12 points of the MTF curve ( equivalent 12 points of LogMar VA) was used for analysis. Results.

利用人眼点扩散函数分析系统（PSF-1000）检查和评估26例近视散光患者（年龄18~28岁，球镜–3.00DS~-6.00 DS，角膜散光-0.75DC ~-3.00DC）在裸眼、配戴散光软性角膜接触镜和透氧性硬性角膜接触镜三种全矫状态的光学成像质量，采用26眼屈光介质MTF曲线中的12个点（即分别等同于对数视力表4.0~5.1的12个点）进行比较和统计学分析，为了避免主观误差，三种矫正方式的先后顺序随机选择。

The associated factors, clinical signs, treatment and prognosis were discussed. Result: Nine patients (6 female and 3 male) were included in this study. All of the patients were associated with myopia, ranging from -0.5 diopters to -5.0D. Gonioscopy revealed a dense homogeneous pigmented band seen over the entire circumference of the trabecular meshwork in all patients; however, no patients with iris transillumination defects were detected. Two of the patients developed pigmentary glaucoma and were treated with β-blocker, miotics and argon laser trabeculoplasty.

结果：九病例中有六位女性及三位男性，所有的病例皆有近视，分布於负零点五至负五点零屈光度，所有的病例在隅角镜检查皆可观察到浓厚的色素沈积在小梁组织，然而在这些病例并没有发现到有典型之虹膜透光缺损：其中有两例后来发展成色素性青光眼，以乙型阻断剂、缩瞳剂和氩氮雷射小梁整形术治疗后，病情控制稳定。

Undoubtably myopia is a serious problem among the teenagers.

毫无疑问，在我国年青人当中近视是一个很严重的问题。

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。

If a person is short-sighted,images are focused in front of their retina,and if a person is long-sighted,images are focused beyond their retina.

人如果近视的话，图像就会聚焦在视网膜前方，如果远视的话，图像就会聚焦在视网膜之后。

Are you short-sighted or long-sighted?

你是近视还是远视？
