The vitreous changes in 148 eyes with sudden onset of floaters were evaluated biomicroscopically and documented photographically using an El Bayadi-Kajiura aspherical preset lens mounted on a photo slit lamp. Posterior vitreous detachment (PVD) was found in 83% of the eyes. In those eyes, the primary causes of floaters were prepapillary glial tissue on the posterior hyaloid membrane and minimal vitreous hemorrhage. In eyes with no PVD, intravitreous fiber-like opacities corresponding to the patient's symptoms were present in the posterior vitreous cavity near the retina. These opacities were found on the plicated membranes of Cloquet's canal, or were associated with liquefaction of the gel. The symptoms of patients 50 years of age or older were related to the acute onset of PVD in 95% of the cases. The complaint of multiple small floaters was frequently associated with vitreous hemorrhage and retinal breaks.
对148例突然出现飞蚊症的患者的玻璃体变化进行了生物显微镜评估，并使用安装在照相裂隙灯上的El Bayadi-Kajiura非球面预设透镜进行了照相记录。83%的患者出现了玻璃体后脱离（PVD）。在这些患者中，飞蚊症的主要原因是后玻璃体膜上的视乳头前神经胶质组织和少量玻璃体出血。在没有PVD的患者中，视网膜附近的玻璃体后腔中存在与患者症状相对应的玻璃体内纤维状混浊物。这些混浊物出现在克洛凯管的褶皱膜上，或与凝胶液化有关。50岁及以上患者的症状在95%的病例中与PVD的急性发作有关。多发性小飞蚊症的主诉通常与玻璃体出血和视网膜裂孔有关。
