Biomicroscopy and ultrasonography were used to examine the vitreous bodies of 22 unselected eyes with idiopathic detachment of the retina. In addition, the subretinal space was examined acoustically. Optical examination showed severe degeneration of the vitreous body in 17 cases, slight degeneration in four cases, while in one case optical examination was not possible. Acoustic examination yielded the same results. The subretinal space was acoustically heterogeneous in all the eyes examined. In two eyes, the subretinal fluid reflected rapidly moving echoes, in the other 20 the movements were slow. The echoes from the degeneration of the vitreous body were 5-10 dB higher in amplitude than those from the subretinal space. Both optical and acoustic methods should be used to ascertain the disposition of the other eye to detachment of the retina.
应用生物显微镜检查和超声检查对22例未经挑选的特发性视网膜脱离患眼的玻璃体进行了检查。此外，还对视网膜下间隙进行了声学检查。光学检查显示，17例玻璃体严重变性，4例轻度变性，1例无法进行光学检查。声学检查得出了相同的结果。在所有受检眼中，视网膜下间隙的声学表现均不均匀。2只眼中，视网膜下液反射出快速移动的回声，其他20只眼中则为缓慢移动。玻璃体变性产生的回声振幅比视网膜下间隙产生的回声高5 - 10分贝。应同时采用光学和声学方法来确定另一只眼发生视网膜脱离的倾向。
