以前眼科医生经常对判断眼内或眶内异物的部位感到困难,CT检查则有很大助益。作者报告一例24岁男性患者,4年前有枪伤史,在常规眼科检查发现左眼瞳孔散大,右侧颅顶骨区有很多金属碎片。这次检查前5个月,患者曾治疗过左眼金属角膜擦伤。患者双眼视力为6/6,左眼瞳孔扩大为7mm,对光反应迟纯,虹膜异色,颞上方角膜有穿通瘢痕,双眼眼压正常。作者怀疑眼部为铁锈症,但房角镜检查、扩瞳后配合巩膜加压眼底检查都未发现球内异物。双眼视网膜电流图正常,眶部X线片未发 Ophthalmologists often find it difficult to determine the location of intraocular or intraorbital foreign bodies in the past, and CT examination can be very helpful. The authors report a 24-year-old male with a history of gunshot wounds 4 years earlier. There was a large left-eye mydriasis in the conventional eye exam and a large number of metal fragments in the right parietal region. Five months prior to this examination, the patient had been treated with a left-eye metallic corneal abrasion. Binocular vision in patients with 6/6, left pupil dilated to 7mm, the light response to pure, iris heterochromic, temporal corneal puncture through the sclera, normal intraocular pressure. The author suspected that the eye is rust disease, but gonioscopy, dilatation and sclera with fundus examination fundus examination have not found intraocular foreign bodies. Eyes normal retinal current pattern, orbital X-ray was not issued
