眼药水滴眼科常用的治疗方法。一般认为:滴眼肘,将药液滴入眼内下穹窿部结膜内1～2滴,这种滴量是否合适?结膜囊内存在着一定量的液体,如果滴入药物较多,超过结膜囊容量就将溢出眼外。我国人结膜囊容量一般在20微升以下,也即是理想的滴量每次应在20微升以下。目前市售的普通塑料滴眼瓶和柱式细嘴玻璃滴眼瓶每滴滴量约在40.8～74.8微升之间,远远超过了结膜囊的药容量。因此,目前使用眼药水即使滴眼一滴后一般都有一半以上溢出眼外,造成浪费。 Eye drops eye treatment commonly used methods. Is generally believed that: eye drops elbow, the liquid drops into the intracoveal subfornix conjunctiva within 1 to 2 drops, the drop volume is appropriate? There is a certain amount of liquid conjunctival sac, if more drops into the drug, more than the conjunctiva Pouch capacity will overflow the outside world. My conjunctival sac capacity is generally below 20 microliters, which is the ideal volume should be below 20 microliters each time. At present, the average drop volume of the ordinary plastic eye drop bottle and the column slim drop glass eye drop bottle is between 40.8 and 74.8 microliters, far exceeding the drug capacity of the conjunctival sac. Therefore, the current use of eye drops, even after dropping a drop of eye drops are generally more than half, resulting in waste.
