摘要

統計104位飛蚊症病例，共141隻眼睛，我們發現有85隻眼睛有後玻璃體剝離，占60.3%。其中四十歲以上的患眼發生比率更高達83.9%。在有後玻璃剝離的眼睛中，還發現9.4%併有視網膜裂孔，而沒有後玻璃體剝離的眼睛只有3.6%併有視網膜裂孔。另外在38隻沒有症狀的眼睛中也有12隻眼睛被發現有後玻璃體剝離。本文同時比較近視與後玻璃體剝離的關係，發現近視三百度以上的眼睛，發生後玻璃體剝離的年齡比正常人有極明顯的降低。

One hundred and forty-one eyes of myodesopsia were investigated for posterior vitreous detachemnt (PVD). The incidence of PVD was 60.3% in the entire group studied but it increased to 83.9% if only patients older than 40 years were included. Incidence of retinal break was significantly higher in the PVD eyes (9.4%) than of non-PVD eyes (3.6%). Those patients with myopia more than -3.0D developed PVD earlier. It implied that the incidence of PVD was affected by the degree of refractive error. For control study we studied 38 symptomless eyes and among them 12 eyes were found to have PVD without any break. In our study, majority of the patients with PVD complained of diffuse dots, lines, webs or shadows.
