Abstract

The authors had recently experienced a case of optic nerve atrophy leading to blindness caused by acute carbon monoxide poisoning and reviewed the literatures of ocular changes secondary to the poisoning. The major findings were intraorbital bleeding, exophthalmos, ptosis, impairment of the ocular movement, superficial retinal hemorrhage and narrowing of the retinal vessels, the last two being thought to be degenerative changes leading to thrombosis of central retinal artery. At the 21th day after the accident exophthalmos, ptosis and ocular movement were recovered to normal but in the fundus retinal vessels could be found hardly and disc was pale.
