目的：探讨高度近视眼球壁形态改变特征与视功能之关系。方法：对140例（280只眼）屈光度在一6．25～30．00D之间的近视患者，进行眼球拍长、角膜曲率等系列数据检测，经统计学处理。结果：①高度近视的矫正视力随屈光度增加而明显下降，差异有显著性意义（P＜0．01）。②96.1％的眼球前后内径轴长增长，其屈光度随之增高。③有27．l％的眼球突出度向前变突。④前表面角膜曲率与正视眼球相比无明显差异。⑤有80．7％的眼球发生后巩膜葡萄肿。⑥有82．3％的眼球发生视神经萎缩及视盘萎缩弧斑。⑦有5．3％的眼球发生眼内压升高。结论：由于高度近视眼球壁发生一系列病理性改变，因而导致临床上视功能严重受损，是视力不能矫正的主要原因。
Objective: To investigate the relationship between the morphological changes of the wall of the high myopia and visual function. Methods: One hundred and forty cases (280 eyes) of myopic patients with refraction between 6.25 and 30.00D were enrolled in this study. The data of eyeball racket length and corneal curvature were measured and statistically analyzed. Results: (1) The corrected visual acuity of high myopia decreased significantly with the increase of diopter, the difference was significant (P <0.01). 96.1% of the ocular diameter before and after the axial growth, the diopter increased. ③ There are 27. l% of the prominence of the sudden protrusion. ④ anterior corneal curvature and no significant difference compared with the normal eyeball. ⑤ 80.7% of the eye after the scleral staphyloma. ⑥ 82.3% of the optic nerve atrophy and optic disc atrophy arcuate. ⑦ 5.3% of the ocular hypertension occurs. Conclusion: Due to a series of pathological changes in the wall of high myopia, which lead to serious impairment of visual function, it is the main reason that vision can not be corrected.
