n.正视眼
Objective To study the characterstics of retinal detachment in emmetropia. 摘要目的对正视眼孔源性视网膜脱离临床特点进行分析。
Conclusion the corneal suface of children with emmetropia has toric shape. 角膜曲率计与角膜地形图仪对于中央区角膜曲率测量有很好的一致性；
This trend towards emmetropia has been described in many species,include human. 本研究对几种常用于近视研究的动物正视化过程做一综述并与人做了简单的对比。
The dioptric equivalent of the near point of emmetropia(or the ametropia corrected)is the amplitude of accommodation. 正视眼(或屈光不正矫正后)近点的等效焦度称为调节幅度。
Conclusion It is easier to suffer retinal detachment in emmetropia when they are over 50 years old. 结论正视眼孔源性视网膜脱离多见于50岁以上年龄患者，双眼发病较少。
ConclusionSclera of high myopia is more flexibly and its load bearing capacity is lower than emmetropia . 结论高度近视眼与正常眼相比更容易发生变形,具有较低的承载能力。
