摘要

目的：為了評估高度近視視神經盤陷凹和視神經盤週邊地區的變化。
方法：我們回溯研究2123名高度近視患者（超過－6.0D）及261位近視低於－6.0D。測量其屈光度、眼軸長及視神經之立體相片。
結果：四類型的視神經盤陷凹，其陷凹程度在高度近視組及對照組並無統計上差異。然而視神經週邊半月斑的大小和屈光度及眼軸長及年齡均有相關。週邊硬式半月斑通常合併於更高度近視及長眼軸及較大年紀。
結論：視神經盤陷凹型態及程度均和近視度數無關，然而視神經盤週邊變化如半月斑大小及型態則和年齡、近視屈光度及眼軸長有關。

Purpose: To evaluate the cupping of the optic disc and changes of the parapapillary region in highly myopic eyes. Methods: We retrospectively studied 2123 highly myopic subjects with refractive errors greater than -6.0D and a control group of 261 subjects with myopia of less than -6.0D. Measurements included cycloplegic refraction, biometric axial length and optic disc stereo-photographs. Results: The incidence of cup/disc ratio and 4 types of disc cupping were not significantly different between highly myopic subjects and control subjects. However, the size of parapapillary crescent was correlated with refractive status, axial length and aging. Parapapillary hard crescent was also associated with more myopic, longer axial length and older subjects. Conclusions: Optic disc cupping did not show significant changes with myopic status. However, parapapillary changes of optic disc such as the size and type of parapapillary crescent correlated with the age, myopic refraction and axial length.
