屈光正常

In the anisometropic amblyopia group, the theoretic figure and the actual figure is different (P0.05); and the aniseikonia after being corrected is different(P=0.0040.05); the stereopsis is different obviously P=0.008

立体视与正常组和屈光不正性弱视组差别有显著统计学意义(P0.05)；立体视与屈光参差性弱视组和对照组差别有显著统计学意义P

Methods The optical calculation was taken as the following by using the parameter of Gullstrand model eye:①The refraction of silicone filled eye in non-accommodative status;②The refraction of silicone filled eye in non-accommodative status;③The aniseikonia analysis when one eye filled with the silicone oil;④The IOL power re-calculation.

采用Gullstrand模型眼参数进行以下分析：①非调节状态下正常眼球与硅油填充后眼球的屈光状态；②调节状态下正常眼球与硅油填充后眼球的屈光状态；③无晶状体眼玻璃体腔填充后的屈光状态；④正常眼球与填充硅油后视网膜像放大率变化；⑤硅油填充后的白内障人工晶状体植入术人工晶状体度数的变化。

ABSTRACT Objective The purpose of this paper is to investigate the ef fects of ametropia and anisometropia on visual development. Methods Animal models were made by binocular and monocular chronic atropinization.

用幼猫双眼或单眼慢性阿托品化的方法，造成屈光不正或屈光参差的弱视动物模型，在整个视觉发育期，连续检测其条栅视力和对比敏感度函数，并与正常幼猫相比较。

The "emmetropia" in geometrical optics and "the normal eye of refraction" in biomedicine were two different concepts, and should be differentiated.

几何光学的"正视眼"与生物医学角度的屈光"正常眼"是两个不同概念，应予以区分

The experiment objects are 15 age-related cataract patients (28 target eyes). Furthermore, this study makes an Age-related Cataract Image Blurring Program which can blur the digital eye chart for the second experiment -"Blurry Image Recognition Experiment". The purpose of the second experiment is to decrease the visual acuity of young healthy eyes (vision with correction, 1.0) and to gather statistics for recognition critical point. These statistics represent different blurry degree of visual degeneration and are used to construct the simulation function of testbed.

透过本研究撰写之老年性白内障影像模糊化程式，将电子式视力检查表进行模糊影像处理，并由视觉屈光正常之受测者(或矫正视力为1.0之受测者)进行模糊影像辨识实验，完成每行视标之可辨识临界点之统计，再将统计数据应用於平台制作，以模拟不同视力退化程度之功能。

The condition of the normal eye when parallel rays are focused exactly on the retina and vision is perfect.

屈光正常当平行光线恰好聚焦于视网膜并形成清晰视觉时正常眼睛的状态

The CSF of ametropic group a nd of anisometropic group is below normal.

屈光不正组和屈光参差组猫CSF均低于正常，且以屈光参差组更明显。

We investigated the characteristics of visual evoked potentialsof the eyes with normal visual acuity in 84 children of whom 20 were normal,28 of anisometropic amblyopia,8 of ani-sometropic amblyopia already cured, 8 pairs of monozygotic and 6 pairs of dizygotic twins with ambly-opia.

对84例儿童正常视力限的视觉诱发电位（visualevokedpotential，VEP）进行了分析，其中正常儿童20人，屈光参差性弱视儿童28人，治愈的屈光参差性弱视儿童8人，单卵双生子8对，双卵双生子6对。

Results:1. In the central region the N_1-P and P-N_2 amplitudes of mfVEP of the strabismic amblyopic and anisometropic amblyopic eyes were reduced compared with the fellow eyes and the normal eyes.

结果： 1。斜视性弱视和屈光参差性弱视mfVFP的N_1-P振幅和P-N_2振幅在中央区较对侧眼和正常对照组降低；屈光不正性弱视N_1-P振幅和P-N_2振幅在中央区较正常对照眼降低，其差异均有统计学意义。

In the central region the N_1-P and P-N_2 amplitudes of mfVEP of the inisometropic amblyopic eyes were reduced compared with the normal eyes.2. In strabismic amblyopia eyes and anisometropic amblyopic eyes the latencies of mfVEP were markedly prolonged.

斜视性弱视和屈光参差性弱视的mfVFP特征峰潜时在各环都较对侧眼和正常对照组延长；屈光不正性弱视患者的特征峰潜时在各环较正常对照组延长，其差异均有统计学意义。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
