We present the results obtained after studying two groups of patients with dynamic register techniques, using A-scan, standardised A-scan following Ossoinig's procedure and B-scan. One group comprised 50 patients with retinal detachment and proliferative vitreoretinopathy while the other consisted of 15 patients with choroidal melanoma. In the group of patients with retinal detachment and proliferative vitreoretinopathy 90% of cases demonstrated waves with 100% amplitude on A-scan when the ultrasound beam was directed perpendicularly over the detached retina. Likewise in these same 90% of cases we observed a small split in the wave peak during the after movements. Conversely on B-scan 80% of these patients with retinal detachment and proliferative retinopathy showed retinal mobility. In the group of patients with choroidal melanoma rapid spontaneous movements were detected in the internal echoes on A-scan and standardised A-scan. Moreover in 3 of the 15 cases (those of greatest size) movement could also be detected on B-scan.
我们展示了运用动态记录技术对两组患者进行研究后所获得的结果，这些技术包括A扫描、遵循奥索伊尼格程序的标准化A扫描以及B扫描。一组由50例视网膜脱离和增殖性玻璃体视网膜病变患者组成，另一组由15例脉络膜黑色素瘤患者组成。在视网膜脱离和增殖性玻璃体视网膜病变患者组中，当超声束垂直指向脱离的视网膜时，90%的病例在A扫描上显示出振幅为100%的波。同样，在这90%的病例中，我们在后续运动期间观察到波峰出现小的分裂。相反，在B扫描中，这些视网膜脱离和增殖性视网膜病变患者中有80%显示出视网膜活动。在脉络膜黑色素瘤患者组中，在A扫描和标准化A扫描中检测到内部回声有快速的自发运动。此外，在15例病例中的3例（最大尺寸的那些病例）中，在B扫描上也能检测到运动。
