间质混浊眼视网膜脱离的超声诊断

Ultrasonographic diagnosis of detachment of retina with the opacity of ocular media.

目的 本文总结了因间质浑浊而要求B超检查,并经临床最后诊断确认为视网膜脱离(包括手术及各种眼底镜、三面镜随访检查结果。其中有27例行巩膜透热电凝术。)的60只眼球,并对其超声图像特征进行了分析。方法 美国产RT—3600,BIOSOUN6D—AU4超声诊断仪,线阵探头,频率7.5～10.0MHz。病人取仰卧位,闭眼,探头涂耦合剂直接置于眼皮上,多切面、多角度动态扫查。结果 全组60只眼中,超声诊断为视网膜脱离的有59只眼,根据其声像图特点可分为三类:一、视网膜局部脱离(39只眼),二、视网膜全脱离(14只眼),三、视网膜全脱离伴脉络膜脱离(6只眼)。超声诊断与临床最后诊断的符合率为98.3％(59/60)。结论 根据超声图象中眼球玻璃体内线状回声光带的不同形态可大致判断视网膜脱离的程度,为视网膜脱离的临床诊断、手术方式、疗效观察等提供有用的信息。

Purpose 60 eyes with the opacity of ocular media were detected by ultrasonography and confirmed by operation and fundus oculi examinations.Methods High frequency ultrasonographic instrument, line probe, 7. 5 - 10. 0MHz. Results Ultrasound imaging patterns were obtained in 59 eyeballs with opacity of ocular media, including merodialysis of retina(39 cases), all retinal detachment(14cases), detachment of retina and choroid (6 cases) . The ultrasound diagnostic correct rate was 98.3%(59/60) .Conclusion Analysis of ultrasound imaging patterns can be helpful to judge the extent of detachment of retina.
