目的:寻找一种确实可行的B型超声波检查方法,便于观察玻璃体手术眼内气体、硅油、加压填充后的眼内变化。方法:采用法国产(BV I)A/B型两用超声诊断仪,对160例玻璃体视网膜手术后的患者采取仰卧位和低头位进行眼部超声波检查并比较分析。结果:对于硅胶环扎带、加压块采用仰卧位即可以查出它们的位置,而硅油或气体填充则需改变头位方能显示视网膜回声。结论:超声波通过改变患者体位可观察玻璃体视网膜手术后的眼内情况。
OBJECTIVE: To find a real feasible B-mode ultrasonic examination method to observe intraocular gas and silicone oil in vitreous surgery and to observe intraocular changes after filling with pressure. Methods: A total of 160 patients with vitreoretinal surgery were examined by ultrasound with BV I A / B dual-purpose ultrasound scanner. Results: For silicone banding, the pressure block in the supine position can be found in their position, and silicone oil or gas filling the head position can be changed to show retinal echo. Conclusion: Ultrasound can observe intraocular conditions after vitreoretinal surgery by changing the patient’s position.
