Abstract. We studied tissues from 2 eyes of pterygium regarding hyaluronan,hyaluronic synthases,and CD44. Tissues were surgically obtained from females aged 70 and 76 years. Hyaluronan is a composite of extracellular matrix and is involved in maintaining the three-dimensional tissue structure. It is produced by hyaluronic synthases with CD44 acting as the receptor. These three substances are involved in various biological processes including cell migration and proliferation. Hyaluronan was quantitated using an ELISA. Expression of hyaluronic synthase 2 and CD44 was evaluated by RT-PCR method. One specimen contained 1.0μg/ml of hyaluronan. Both specimens showed expression of hyaluronic synthase 2 and CD44. These findings show that pterygium contains the three substances and that the system composed of them is involved in the pathogenesis of pterygium.
