为了解脉络膜上腔出血（脉络膜暴发性出血）的Ｂ超图像特征，对手术或外伤等所致的疑为脉络膜上腔出血病例应用Ｂ超检查进行诊断。使用眼科专用超声诊断仪，探头频率为１０兆赫。对眼内各个方位使用正常灵敏度进行探测。结果：４９例４５眼超声显像特征：显示向玻璃体腔暗区突起的边界清晰、光滑的半球形强回声区。光点的密与疏代表出血量的多少，出血范围的大小表现为一个至多个半球形或六个半球形强回声区。结论：应用Ｂ超检查可以明确脉络膜上腔出血的诊断，并随访治疗的效果。
To understand the characteristics of B-mode ultrasound in choroidal hemorrhage (choroidal fulminant haemorrhage), B-mode ultrasonography was used to diagnose cases of suspected suprachoroidal hemorrhage due to surgery or trauma. Using an ophthalmic ultrasound scanner, the probe frequency is 10 MHz. Use normal sensitivity to all directions in the eye. Results: Forty-five eyes of 45 patients underwent echographic imaging showing clear and smooth hemispherical hyperechoic regions protruding toward the dark area of the vitreous cavity. Spots of dense and sparse on behalf of the amount of bleeding table, the size of the bleeding showed the size of one or more hemispherical or hemispherical hyperechoic area. Conclusion: B-ultrasound can confirm the diagnosis of choroidal hemorrhage and follow-up treatment.
