However, few studies have examined the contribution of matrix metalloproteinases (MMP) to either diagnostic or prognostic potential in pterygium. In this study, we investigated the contribution of a polymorphism in the promoter region of MMP-8 (-799C/T) and two non-synonymous polymorphisms (Val436Ala and Lys460Thr) to pterygium. Materials and Methods: In this study, 134 patients with pterygium and 268 non-cancer controls patients were collected and the MMP-8 -799C/T, Val436Ala and Lys460Thr polymorphic genotypes of each subject were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The results showed that the three polymorphisms investigated were not significantly associated with risk of pterygium. In addition, the stratified analysis showed that there was no interaction between MMP-8 genotype with age or gender on pterygium risk determination. Conclusion: Polymorphisms at MMP-8 -799C/T, Val436Ala and Lys460Thr may not mainly contribute to determining personal susceptibility to pterygium in the Taiwanese examined.
