[Iatrogenic central artery embolism].

This paper presented 3 cases of central retinal artery embolism (CRAE) caused by the drug injection at the head and neck. In two of the three cases, the emboli were formed by the suspended drug which entered CRA resulting in the occlusion. Another case was caused by the large amount of meglucamini diatrizoas which was injected too quickly during angiography. The CRA was filled up with fluorescein in a very short time, which lead to ischemia and hypoxia of the retina. This paper stressed the importance of early diagnosis and prompt treatment. The authors also Discussed the method of drug injection at the head and neck.
