Oksalus(1957)开始用超声波检查诊断视网膜脱离和鉴别各种类型的视网膜脱离。Ossoinings(1971)系统地介绍了超声波检查技术。在超声波检查时,脱离的视网膜在眼球后节呈现尖而高的波形,与眼球后壁的高波之间为一平段,在临床上相当于视网膜下积液部份,平段的长度相当于视网膜脱离的高度。Ossoinings(1972)报导,视网膜脱离的高度超过0.7mm、宽度超过0.2～0.5mm就可用超声波诊断出来。本文作者所用超声波探头的频率是12MHz,这样检查的精确度可达0.07～0.1mm。超声检查还可发现视网膜皱襞、玻璃体膜及条索与已脱离的视网膜
Oksalus (1957) started using sonography to diagnose retinal detachment and to identify various types of retinal detachment. Ossoinings (1971) systematically introduced ultrasound examination techniques. In the ultrasound examination, the detachment of the retina showed sharp and high waveform in the posterior segment of the eye, and the posterior wall of the high wave between a flat section, equivalent to the clinical part of the subretinal fluid, flat segment length equivalent to the retina Detach from the height. Ossoinings (1972) reported that retinal detachment height more than 0.7mm, width of more than 0.2 ~ 0.5mm can be diagnosed by ultrasound. The frequency of the ultrasonic probe used by this author is 12MHz, so the accuracy of checking can reach 0.07 ~ 0.1mm. Ultrasonography can also be found in the retina fold, vitreous membrane and cords and detachment of the retina
