The present invention is an aqueous ophthalmic composition including two kinds of methyl cellulose, polyethylene glycol, polyvinyl pyrrolidone, and citric acid or a pharmaceutically acceptable salt thereof. The composition of the present invention maintains a low viscosity at around room temperature, but its viscosity rapidly increases due to the heat near body temperature, while it has thixotropy even when it has gelated.本發明是一種眼科用水性組成物，其係含有2種類的甲基纖維素、聚乙二醇、聚乙烯吡咯酮、及檸檬酸或其藥學上可容許的鹽。本發明的組成物在室溫附近維持低黏度，且其黏度因體溫附近的熱而急速增加，即使凝膠化也具有搖變性。
