B型超声检查在硅油填充眼硅油取出术前的应用价值

目的结合临床探讨玻璃体内硅油填充眼B型超声检查的声像学特征,以及对硅油取出的时机、手术方式和术后预后评估的参考价值。方法对30例（30只眼）玻璃体内硅油填充眼行B型超声检查,测量眼轴,观察晶状体、玻璃体腔、硅油及眼底回声情况。结果 30例玻璃体内硅油填充眼可分为：（1）视网膜脱离;（2）视网膜增生机化;（3）视网膜正常。超声检查和术中所见诊断符合率可达86.66%（26/30）。结论 B型超声检查眼部操作简便,可做出直观性图像诊断,对手术方式的选择及预后有客观的参考价值。

Application of ultrasonic examination before removal of silicone oil from silicone oil-filled human eyes

Objective By combining clinical data,the B-scan ultrasonographic features of silicone oil-filled human eyes are discussed to provide a reference for the timing of silicone oil removal,selection of surgical procedure,and prognostic evaluation.Methods Ultrasonic inspections were performed on thirty silicone oil-filled human eyes,with axial eye length measured and lens,intravitre,silicone oil,and ocular fundic echo observed.Results Thirty silicone oil-filled human eyes are accompanied by：①retinal detachment,②vitreous proliferation and organization,③retinal reattachment,and so on.The diagnostic coincidence rate reached 86.66%.（26/30）.Conclusion Ultrasonic scanning of eye examination plays an important role in the operative selection and prognostic evaluation because of its convenient Procedure match high quality picture of crystalline lens and direct figure diagnosis.
