回顾性研究了12年间诊断为后部玻璃体脱离(PVD)的700例818眼的发病年龄与屈光不正的关系。其中男性171例198眼,女性529例620眼。所有病例除屈光不正外,均排除其它视网膜玻璃体病患;结合病史,经间接眼底镜、三面镜及装有+90D透镜的裂隙灯检查而确诊。结果:后部玻璃体脱离的发病年龄与屈光不正有关;所得回归方程为:发病年龄=0.86×屈光度D+61.21,相关系数为0.400 A retrospective study of 12 patients diagnosed with posterior vitreous detachment (PVD) in 700 cases of 818 eyes the age of onset and refractive error relationship. Among them, 171 were male, 198 eyes, and 529 were 620 eyes. All cases except for refractive errors were excluded from other retinal vitreous diseases; combined with medical history, confirmed by indirect ophthalmoscope, three-mirror and slit lamp with + 90D lens. Results: The age of posterior vitreous detachment was related to refractive error. The regression equation was: onset age = 0.86 × diopter D + 61.21, correlation coefficient was 0.400
