目的 觀察魚腥草滴眼液治療急性卡他性結膜炎的臨床療效及安全性。方法 將100例急性卡他性結膜炎患者隨機分為治療組（50例）和對照組（50例），治療組給予魚腥草滴眼液，1滴/次，6次/d，對照組給予復方熊膽滴眼液，用法和用量同治療組，兩組均治療7 d。治療結束后，比較兩組患者的疾病西醫(yī)療效和中醫(yī)證候療效，同時觀察兩組患者有無不良反應發(fā)生。結果 治療組西醫(yī)臨床療效的總有效率為97.92%，對照組為86.96%，兩組比較差異有統(tǒng)計學意義（P＜0.05）。在中醫(yī)證候白睛紅赤、胞瞼紅腫、眵多膠結、怕熱畏光方面，治療組優(yōu)于對照組（P＜0.05），目癢、流淚、口苦、尿黃證候兩組差異無統(tǒng)計學意義（P＞0.05）。結論 魚腥草滴眼液治療急性卡他性結膜炎療效較好，臨床應用安全。
