目前对眼内非磁性异物的处理,意见尚不一致。或认为不论有无影响,一律取出;或认为应采用保守疗法。二者均有不利影响。手术摘出异物,即使技术和设备条件优越,对患者的视力均可造成损害。而有些异物并无化学毒性,可耐受很长时间而视力不受影响,因而有人建议用保疗法。目前尚无可靠方法能在异物对眼组织造成不可逆损害之前,即被发现。非磁性异物在眼内的主要危险是铜性异物的分解。过去对铜性异物的分解尚无一种直接测定的方法。晚近用X线能谱测定法能测出眼内金属异物分解出的微量元素,从而避免了眼内非磁性异不论对眼组织有无损害一律取出的弊病。作者将铜性异物植入于兔眼内,经一段时期后,用X线能能谱测定法、眼底镜检查法、及视 At present, the treatment of intraocular non-magnetic foreign bodies, opinions are not consistent. Or that with or without influence, be removed; or that should be conservative treatment. Both have adverse effects. Surgical removal of foreign body, even if the technical and equipment conditions are superior to the patient’s vision can cause damage. Some foreign body does not have chemical toxicity, can withstand a long time without affecting the visual acuity, so it is recommended to use therapies. There are currently no reliable methods to detect foreign bodies that cause irreversible damage to the eye tissue. The main danger of non-magnetic foreign bodies in the eye is the decomposition of copper foreign bodies. In the past there was no direct method for the determination of copper foreign matter. Recent X-ray spectrometry can be measured intraocular metal foreign body decomposition of trace elements, so as to avoid intraocular non-magnetic abnormalities regardless of whether the damage to the eye tissue all the shortcomings removed. The authors implanted copper foreign body in the rabbit eye, after a period of time, using X-ray spectrometry, funduscopic examination, and visual
