摘要

選擇13例單側高度近視，觀察其兩眼間高度屈光誤差時，屈光組成及眼底的變化。觀察結果：(1)單側眼軸過長是單側高度近視的主要原因。(2)單側高度近視者其兩眼間的角膜屈光力意義上並無差別。(3)生理性近視眼的中央眼底並無變化，然而病理性近視眼的中央眼底都有程度不一的視盤新月及鋪磚狀變化。(4)病理性近視眼眼軸的過長似乎不隨著年齡的增大而惡化，而徒極葡萄腫和地圖狀脈絡視網膜變性隨著年齡的增大而惡化。(5)周邊視網膜變性兩眼皆有可能發生，而與是否為生理性近視眼或者病理性近視眼無關。但是病理性近視眼過長的眼軸會使周邊變性程度更為嚴重。

13 cases of unilateral high myopia, cases of high anisometropia, were collected to evaluate refraction components and fundal changes. The clinical observation were:
1. The unilateral excessive prolongation of axial length is the principal cause of unilateral high myopia.
2. There is no significant difference of corneal refraction power between physiologic and pathologic myopic eye in the same patient.
3. There are no central fundal changes in any physiologic myopic eye. However in pathologic myopic eyes, they always have disc creascents and tessellation in different severity.
4. It seems that the excessive axial length of pathologic myopic eye does not get worse with age. Except the posterior staphyloma and the geographic chorioretinal degeneration.
5. The occurrence of peripheral fundal changes could happen in both eyes, independent of either physiologic or pathologic myopia. But the excessive axial length of pathologic myopia makes peripheral fundal changes more apparent.
