[2 cases of acute retrobulbar neuritis by thinner inhalation; detected methanol of high concentration in gas phase assay].

We encountered two cases of acute retrobulbar neuritis due to lacquer thinner vapor sniffing. Two men, aged 21 and 23, had been addicted to thinner sniffing for many years. After they became conscious of their symptoms of slight visual disturbance, they continued the sniffing for several days until they lost their vision.
