PURPOSE To determine the cellular distribution and activation of MMP-2 and MMP-9 in human pterygium. METHODS The expression and activation of MMP-2 and MMP-9 were determined by immunohistochemistry and quantitative gelatinase zymography from 27 pterygia (26 cases, 18 eyes in stationary pterygia and 9 eyes in progressive pterygia) and 6 normal conjunctival specimens. RESULTS MMP-2 was expressed in all pterygium examined, specifically localized to the epithelium. MMP-9 was the most abundant… CONTINUE READING
