本文回顾了１７８例屈光间质混浊的视网膜脱离超声诊断。不同病种，诊断准确率不同。对于角膜混浊、晶体混浊而无玻璃体严重混浊的病例，仅行Ａ超检查即能明确视网膜是否脱离。非外伤性玻璃体混浊，可先行Ａ超检查，当Ａ超不能明确诊断时再加用Ｂ超检查。外伤性玻璃体混浊，尤其是伴眼内异物或爆炸伤者，应同时行Ａ及Ｂ超检查，结合临床表现才能正确判断视网膜是否脱离，本文还显示，病程长也影响超声诊断的准确性。
This article reviews 178 cases of refractive retinal detachment ultrasound diagnosis. Different diseases, different diagnostic accuracy. For corneal opacity, crystal opacity without severe cases of vitreous opacity, just A-check that is clear whether the retinal detachment. Non-traumatic vitreous opacity, may be the first A-ultrasound, when A-can not be clearly diagnosed with B-ultrasound. Traumatic vitreous opacity, especially with intraocular foreign body or explosive injury, should be simultaneously A and B ultrasound examination, combined with clinical manifestations to correctly determine whether the retinal detachment, this article also shows that duration also affects the accuracy of ultrasonic diagnosis.
