Abstract Details


In this study, we aimed to investigate the roles of mast cells in pterygium pathogenesis and to compare the number of mast cells in primary and recurrent pterygium.


Kagıthane State Hospital, Department of Ophthalmology


In this study, we evaluated 25 eyes of 25 outpatients with pterygium and the 2 eyes of 1 outpatient with pterygium. Twenty-two of pterygium tissues were primary type and twenty-two of them were recurrent type. Normal conjunctival tissues in the upper temporal quadrant of same eyes were included in the control group. The numbers of mast cells in the tissues of primary pterygium group, recurrent pterygium group and control group were compared.The mean mast cell number in the pterygium tissues (8.9±6.5) was statistically significantly higher than the mean mast cell number in the control tissues (6.0±4.7) (p=0.000). Even though the mean mast cell number in the recurrent pterygium tissues (8.3±6.4) was higher than that in the primary pterygium tissues (7.5±4.3), the difference was not statistically significant (p=0.58).


These results suggest that mast cells play an important role in pterygium pathogenesis; however, more studies are necessary to demonstrate the difference between primary pterygium and recurrent pterygium.
