眶深部植物性异物用常规X 线摄片不易发现,B 型超声检查虽有时能显示异物,但不易确定其全貌。利用CT 扫描对临床上怀疑有眶内植物性异物的4例患者进行检查。并通过手术验证,表明CT 扫描具有定性定位诊断价值。例1 黄××男34岁左眼被芦根戳伤8年,流脓2个月,于1990年10月11日入院,住院号347789。左眼被芦苇残根刺伤后,次日昏迷,怀疑颅内血肿,在当地县医院开颅探查,未获得阳性结果而转上海某医院保守治疗3个月。近2个月来。左上睑从原创口经常流脓、流血,考虑为眶骨髓炎,入院治疗。左眼视力60cm 指数。上眶睑沟内侧有一长约4cm 疤痕,其中部有一0.4cm 直径瘘口,深约2cm。视乳头苍白。眼球突出度为14,19(103)。视 Orbital deep plant foreign body with conventional radiography is not easy to find, B-mode ultrasound can sometimes show foreign body, but not easy to determine the whole picture.

And through the surgical verification, indicating that CT scan with qualitative localization diagnostic value.
