It is occasionally difficult to ascertain postoperatively whether a Molteno implant is functioning or not. We have found that ultrasonography (B-scan) is a useful diagnostic tool in assessing tube patency. Polaroid images of 29 ultrasound pictures, 8 with occluded tubes, were taken postoperatively and presented independently to a radiologist and a retinal specialist, who were asked to determine the functioning state of the Molteno implant. In all cases the observers were able to correctly identify whether the tube was patent or not.
术后有时很难确定莫尔滕诺植入物是否在发挥作用。我们发现超声检查（B超扫描）是评估引流管通畅情况的一种有用的诊断工具。术后拍摄了29张超声图像的宝丽来照片，其中8张显示引流管堵塞，这些照片分别交给一位放射科医生和一位视网膜专家，要求他们确定莫尔滕诺植入物的功能状态。在所有病例中，观察者都能够正确识别引流管是否通畅。
