据记载,乙胺丁醇大剂量或长时期服用可导致球后视神经炎,小剂量(15mg/kg/d)或与其它抗结核药联合应用时,则中毒少见。这就给人以小剂量似乎安全的印象。因此,在临床使用中缺乏警惕,不作详细的观察。同时,也可能有部分临床者对此药在眼部的毒性表现,尚缺乏认识。为了观察小剂量对眼部的损害,故对某院住院患者进行调查研究。 It has been reported that ethambutol may cause poisoning of the posterior optic neuritis at high or long-term doses and is less toxic when given in small doses (15 mg / kg / day) or in combination with other anti-TB drugs. This gives the impression that small doses seem safe. Therefore, lack of vigilance in clinical use, without making a detailed observation. At the same time, there may be some clinicians on the toxicity of the drug in the eye, there is a lack of understanding. In order to observe the damage of small doses of the eye, so a hospital inpatient investigation.
