我们用美国ＡＬＬＥＲＧＡＮＨＵＭＰＨＲＥＹ公司生产的８３５型Ａ／Ｂ型超声诊断仪，观察６５只眼有膜状光带的声象图，判断视网膜和玻璃体的关系及视网膜本身的状态，并在术中或术后直接观察眼底验证Ｂ超诊断的准确性。结果显示：诊断正确的有５５只眼，诊断错误的有７只眼，无法证实的有３只眼，即确诊率为８４．６％。在Ｌｉｎ和Ｌｏｇ两种不同的声象图中玻璃体机化膜和视网膜脱离膜也有不同的显示特性，但还需结合临床，排除影响因素，对视网膜状态作出理想的超声诊断。伴有球内异物的屈光间质混浊对Ｂ超的诊断有一定的影响。
We use the United States ALLERGANHUMPHREY company produced 835 type A / B ultrasonic diagnostic apparatus to observe the 65 eyes with a film of light with the audio image to determine the relationship between the retina and the vitreous and the status of the retina itself and during or after surgery Direct observation of the fundus to verify the accuracy of B-ultrasound. The results showed that 55 eyes were correctly diagnosed, 7 eyes were wrongly diagnosed, and 3 eyes were unidentifiable. The diagnosis rate was 84.6%. Vitreous organotypic and retinal detachment membranes also have different display characteristics in Lin and Log two different sonograms, but also need to combine the clinical, exclude the influencing factors, to make the ideal ultrasound diagnosis of retinal state. Blepharoplasty with intraocular foreign bodies has a certain impact on the diagnosis of B-ultrasound.
