The vitreous in both normal eyes of 671 normal subjects was studied biomicroscopically. The results obtained were as follows: 1. In 618 cases of a refractive error less than -3D (group A) and 53 cases of refractive error over -3D (group B), the incidence of posterior vitreous detachment (PVD) in both eyes increased with age and the absence of PVD in both eyes decreased with age. The percentage of cases with PVD in one eye and no PVD in the other eye was less than 22% in all age groups. 2. There was no significant difference in the degree of vitreous liquefaction between the right and the left eyes. The degree of vitreous liquefaction was also age-related. 3. In the cases with PVD in one eye and no PVD in the other eye, a higher incidence of mild vitreous liquefaction was found in group A than in group B. 4. PVD without collapsed vitreous (simple PVD) in both eyes was observed only in group A. 5. Our results indicated that the vitreous findings in both eyes of an individual were almost identical, and PVD may occur with less vitreous liquefaction in group A than in group B.
对671名正常受试者的双眼玻璃体进行了生物显微镜研究。结果如下：1. 在618例屈光不正小于-3D的患者（A组）和53例屈光不正超过-3D的患者（B组）中，双眼后部玻璃体脱离（PVD）的发生率随年龄增加而升高，双眼无PVD的发生率随年龄降低。在所有年龄组中，一只眼有PVD而另一只眼无PVD的病例百分比均小于22%。2. 左右眼玻璃体液化程度无显著差异。玻璃体液化程度也与年龄相关。3. 在一只眼有PVD而另一只眼无PVD的病例中，A组轻度玻璃体液化的发生率高于B组。4. 仅在A组观察到双眼无玻璃体塌陷的PVD（单纯PVD）。5. 我们的结果表明，个体双眼的玻璃体表现几乎相同，且A组发生PVD时所需的玻璃体液化程度可能低于B组。
